On the re-assessment of inequality in Indonesia: household survey or national account?
Yusuf, Arief Anshory
C80 - General
D63 - Equity, Justice, Inequality, and Other Normative Criteria and Measurement
This paper is motivated by the inconsistency between food and non-food ex-penditure estimated from household survey data (SUSENAS) and from nationalaccount (I-O table) and its connection on the issue of inequality in Indonesia.Since non-food expenditure tend to be under-estimated when compared withnational account data, it imply the under-representation of the rich in the cal-culation of inequality in Indonesia. This paper, then applies an approach toreconciling household survey and national accounts data, by re-estimating thesampling weight through minimization of entropy distance of information takinghousehold survey weight as prior, while satisfying some aggregation constraints.The estimated weight then is used to calculate standard indicator of inequalityin Indonesia. The results suggests that while inequality in rural Indonesia doesnot change much, due to possible under-representation of the rich in the survey, inequality in urban Indonesia is highly under-estimated. The "Jakarta factor"seems to account mostly to this discrepancy.

I apply the Beveridge-Nelson business cycle decomposition method to the time series of murder in the state of New York. (1933-2005). Separating out “permanent” from “cyclical” murder, I hypothesize that the cyclical part coincides with documented waves of organized crime, internal tensions, breakdowns in social order, crime legislation, social, and political unrest, and recently with the periodic terrorist attacks in the state. The estimated cyclical terrorist murder component warns that terrorist attacks in the state of New York from 1962 to 2005, historically occur in the estimated turning point dates, of whether a declining, or ascending cycle, and so, it must be used in future research to construct a model for explaining the causal reasons for its movement across time, and for forecasting terrorist murder and attacks for New York.

Paic, Peter
J23 - Labor Demand
C80 - General
Grundlage für die empirische Analyse freiberuflicher Existenzgründungen ist eine möglichst
umfassende Datenbasis, welche relevante Informationen zur Existenzgründung der Freiberufler
beinhaltet und ein realistisches Abbild der Wirklichkeit (Repräsentativität) wiedergeben
kann.
In diesem Kontext vergleicht der Autor sieben informationelle Zugänge auf ihre Eignung im
freiberuflichen Existenzgründungsumfeld. Zu den ausgewählten Datenbasen der Untersuchung
gehören der Mikrozensus des Statistischen Bundesamtes, die Umsatzsteuerstatistik, das
Sozio-oekonomische Panel (SOEP) des Deutschen Instituts für Wirtschaftsforschung (DIW),
das ZEW-Gründungspanel West und das ZEW-Gründungspanel Ost vom Zentrum für Europäische
Wirtschaftsforschung (ZEW), die Beschäftigtenstatistik der Bundesagentur für Arbeit
(IAB-Panel), die Erhebungen des Instituts für Freie Berufe (IFB) und die Allgemeine Bevölkerungsumfrage
der Sozialwissenschaften (ALLBUS) der Gesellschaft Sozialwissenschaftlicher
Infrastruktureinrichtungen (GESIS).
Die Datenbasen werden in Bezug auf ihre Fallzahlen, Repräsentativität, Struktur sowie ihren
gründungsbezogenen Informationsgehalt gegenübergestellt. Der Beitrag schließt mit einem
Fazit zur Eignung der untersuchten Datenbasen ab und gibt einen Ausblick auf das Unternehmensregister
sowie weitere Handlungsoptionen.

In this paper we present a real-life application of a fuzzy expert system aimed at rating and ranking firms. Unlike standard DCF models, it integrates financial, strategic and business determinants and processes both quantitative and qualitative variables. Twenty-one value drivers are defined, concerning the target firm (strategic assets in place and expected financial performance), the acquisition (synergies, quality of management) and the sector (intensity of competition, entry barriers). Their combination via “if-then” rules leads to the definition of an output represented by a real number in the interval [0,1]. Such a number expresses the valuegenerating power of the target firm inclusive of synergies with the bidder (Strategic Enterprise Value). The system may be used for rating and ranking firms operating in the same sector. A
regression analysis using hostile takeovers multiples may be employed to translate the score into price. The real-life case refers to Camuzzi (a natural gas distributor), acquired by Enel, the Italian ex monopolist of electric energy.

The April 21, 2005 issue of the LONDON REVIEW OF BOOKS carried a lead article titled ‘Blood for Oil?’ The paper is attributed to a group of writers and activists – Iain Boal, T.J. Clark, Joseph Matthews and Michael Watts – who identify themselves by the collective name ‘Retort.’ In their article, the authors advance a supposedly new explanation for the wars in the Middle East.
Much of their explanation – including both theory and fact – is plagiarized. It is cut and pasted, almost ‘as is,’ from our own work. The primary source is ‘The Weapondollar-Petrodollar Coalition,’ a 71 page chapter in our book THE GLOBAL POLITICAL ECONOMY OF ISRAEL (Pluto 2002). The authors also seem inspired, incognito, by our more recent papers, including ‘It’s All About Oil’ (2003), ‘Clash of Civilization or Capital Accumulation?’ (2004), ‘Beyond Neoliberalism’ (2004) and ‘Dominant Capital and the New Wars’ (2004).
In their paper, the Retort group credits us for having coined the term ‘Weapondollar-Petrodollar Coalition’ – but dismiss our ‘precise calibration of the oil/war nexus’ as ‘perfunctory.’ This dismissal does not prevent them from freely appropriating, wholesale fashion, our concepts, ideas and theories – including, among others, the ‘era of free flow,’ the ‘era of limited flow,’ ‘energy conflicts,’ the ‘commercialization of arms exports,’ the ‘politicization of oil’ and the critique of the ‘scarcity thesis.’ Nowhere in their article do the authors mention the source of these concepts, ideas and theories; occasionally, they even introduce them with the prefix ‘Our view is. . . .’ Their treatment of facts is not very different. They freely use (sometimes without understanding) research methods, statistics and data that took us years to conceive, estimate and measure – again, never mentioning the source.
These concepts, theories and facts are far from trivial. Until recently, they were greeted with strategic silence, from both right and left. Their publication has been repeatedly denied and censored by mainstream as well as progressive journals (including, it must be said, by the LONDON REVIEW OF BOOKS, that turned down our paper on the subject). They cannot be found anywhere else in the literature, conservative or radical. To treat them as ‘common knowledge’ is deceitful. To cut and paste them without due attribution is blatant plagiarism. The first part of our paper illustrates this process of ‘intellectual accumulation-by-dispossession’ with selected examples.
The issue, though, goes well beyond personal vanity and self-aggrandizement. At the core, we are dealing here with the clash of science and church, with the constant attempt of organized faith – whether religious or academic – to disable, block and, if necessary, appropriate creativity and novelty. Creativity and novelty are dangerous. They defy dogma and undermine the conventional creed; they challenge the dominant ideology and threaten those in power; occasionally, they cause the entire edifice of power to crumble.
For these reasons, the latent purpose of intellectual accumulation-by-dispossession – like the accumulation of private property – is primarily negative. The word ‘private’ comes from the Latin ‘privatus,’ meaning ‘restricted,’ and from ‘privare,’ which means ‘to deprive.’ And, indeed, the most important feature of private ownership is not to enable those who own, but to disable those who do not. It is only through the threat of prevention – or ‘strategic sabotage’ as Thorsein Veblen called it – that accumulation can take place. It is only by restricting the free creativity of society that society itself can be controlled. The second section of the paper explains how the appropriators of ‘Blood for Oil?’ fit this pattern.
The final section of the paper is an epilogue. It describes our failed attempts to get this paper published with The LONDON REVIEW OF BOOKS; Retort’s efforts to mislead us; and some additional insight from their AFFLICTED POWERS, a 2005 Verso book that contains the same plagiarism and more. The epilogue concludes with a few observations on the nature of academic dialectics.

What makes the Difference between Unsuccessful and Successful Firms in the German Mechanical Engineering Industry?

Against a background of rising costs and increasing competition, it is besoming more and more difficult for the small
and medium-sized firms of the German mechanical engineering industry to be economically successful. The thesis
that rapidly changing markets, products and production processes cause serious economic problems for these firms is,
however, a proposition on an average trend. A substantial number of firms are not only capable of coping with these
conditions and challenges, but are even able to expand their business activities, including employment. We may
hypothesize that their product and market strategies as well as their internal mode of operation and organization
differs significantly from those firms doing economically less well.
In order to test the significance of factors which could lead to different levels of success, operationalized with data of
the NIFA panel the method of static microsimulation is applied using the program MICSIM. This particular method
offers the possibility of reweighting the information contained in micro datasets according to restrictions given by
aggregated data (i.e. marginal distributions). The latter will be chosen in such a way that the number of firms with
properties (strategies), hypothetically leading to success in terms of lower excess capacity, are 'artificially', increased
in the sample. The research goal is to find out whether such hypothetical strategies are supported by the data.
The basic finding that certain complex strategies are more often successful demonstrates that unidimensional
approaches to modernize production are of less value. Only in those strategies wehere organization of production,
technical equipment, degree of vertical integration, products and customers are part of an intergrated innovational
strategy, is success most likely to be fuelled.

Microdata Adjustment by the Minimum Information Loss Principle
Merz, Joachim
C81 - Methodology for Collecting, Estimating, and Organizing Microeconomic Data ; Data Access
C80 - General
Microdata have become increasingly important for economic and social analyses. One striking problem with almost
any practical analysis of microdata, microdata as a singular cross or longitudinal sample or within (static)
microsimulation, is to achieve representative results.
In this study a consistent solution of the microdata adjustment problem - that is to achieve representative results by
re-weighting microdata to fit aggregate control data - is presented based on the Minimum Information Loss (MIL)
principle. Based on information theory this principle satisfies the desired positivity constraint on the weighting
factors to be computed. For the consistent solution which simultaneously adjusts hierarchical microdata (e.g.
household and personal information), a fast numerical solution by a specific modified Newton-Raphson (MN)
procedure with a global exponential approximation is proposed.
Practical experiences for large microdata sets in a pension reform analysis with e.g. more than 60.000 households and
240 restrictions simultaneously to be achieved within the Sfb 3 microsimulation model show that this MN procedure
was able to rather largely reduce the computional expenses by 75%. The available efficient PC-computer program
ADJUST is also succesfully applied in a described microsimulation analyses of the recent 1990 German tax reform
investigating the impacts on market and non-market labour supply within the formal and informal economy, and in a
recent firm microsimulation analysion explaining factors of successful firms in the German engineering industry.

and past developments of microsimulation models and their areas of application are
reviewed, focusing on the US, Europe and Australia. Based on general requirements and
components of microsimulation models a microsimulation model's actual working
mechanism are discussed by a concrete example: the concept and realization of
MICSIM, a PC microsimulation model based on a relational database system, an
offspring of the Sfb 3 Statitic Microsimulation Model. Common issues of
microsimulation modeling are regarded: micro/macro link, behavioural response and the
important question of evaluating microsimulation results. The concluding remarks
accentuate the increasing use of microcomputers for microsimulation models also for
teaching purposes

This study on market and non-market labor supply and taxes is based on a theoretical
microeconomic model with multiple labor supply in the formal and informal economy.
This multiple time allocation model, which explicitly takes into account taxes, transfer
payments, socioeconomic characteristics of the individual and the household, is
specified in a multiple three-stage approach explaining the participation probability, the
relevant wages and the hours of work in different activities. Uncompensated and
compensated elasticities on market and non-market labor supply are computed. The
estimates are based on data from the enlarged Sfb 3-Secondary Occupation Survey
1984, enlarged by tax and regional information for the economic situation and labor
demand consideration. This microanalysis will follow the substantial question whether
incentive or disincentive labor supply effects of the 1990 German tax reform are to be
expected. The recent German Tax reform impacts are quantified by a combined
dynamic and static microsimulation approach based on microeconometric estimated
behavioral pattern representative for the Federal Republic of Germany.

Microsimulation as an Instrument to Evaluate Economic and Social Programmes

C80 - General
In recent years microsimulation models (MSMs) have been increasingly applied in quantitative analyses
of the individual impacts of economic and social programme policies.
The suitability of using microsimulation as an instrument to analyze main and side policy impacts at the
individual level will be discussed in this paper by characterizing: the general approach and principles of
the two general microsimulation approaches: static and dynamic (cross-section and lifecycle)
microsimulation, the structure of MSMs with institutional regulations and behavioural response,
panel data and behavioural change, deterministic and stochastic microsimulation, the 4M-strategy to
combine microtheory, microdata, microestimation and microsimulation, and pinpointing applications and
recent developments.
To demonstrate the evaluation of economic and social programmes by microsimulation, two examples
concerning a dynamic (cross-section and life-cycle) microsimulation of the German retirement pension
reform and a combined static/dynamic microsimulation of the recent German tax reform with its
behavioural impacts on formal and informal economic activities of private households are briefly
described. Evaluating the evaluation of economic and social programmes with microsimulation models
finally is followed by concluding remarks about some future developments.

In meiner Antrittsvorlesung versuche ich, meine Forschungs- und Lehrvorhaben in drei Themenkomplexen zu umschreiben. Der erste Themenbereich 'Statistik und Freie Berufe', zugleich Denomination meiner Professur, beschreibt nach den Charakteristika Freier Berufe Möglichkeiten und Grenzen der amtlichen Statistik am Beispiel der längerfristigen Entwicklung der Freien Berufe und der Selbständigen in der Bundesrepublik Deutschland. Neue Erkenntnismöglichkeiten mit eigenen Mikroanalysen und der Unterstützung von Kammern und Verbänden der Freien Berufe verdeutlichen dann die ersten Ergebnisse zu Existenzgrundlagen und Gründungshemmnissen aus unserer Umfrage zur aktuellen Situation in den neuen Bundesländern. Freie Berufe und Europa: Neue Fragestellungen und Analysemöglichkeiten runden den ersten Bereich ab.
Der zweite Bereich thematisiert die empirische Wirtschafts- und Sozialforschung und umschreibt zunächst die wirtschaftliche und gesellschaftliche Bedeutung quantitativer, empirisch fundierter Wirtschafts- und Sozialforschung. An einem Beispiel mikroanalytischer Forschung, einer individuellen Wirkungsanalyse der Steuerreform 1990, charakterisiere ich das, was nach meinem Verständnis zentral für eine empirische Wirtschafts- und Sozialforschung ist: die problemorientierte kombinierte theoretische, datenmäßige, methodengerechte Fundierung einschließlich der Simulation von Alternativen - hier mit der Verbindung von Mikroökonomie, Mikrodaten, Mikroökonometrie und Mikrosimulation.
Der dritte Bereich schließlich bringt die Dinge zusammen: Statistik und Freie Berufe im Rahmen einer empirischen Wirtschafts- und Sozialforschung. Vor dem Hintergrund einer in diesem Sinne angewandten Statistik auf der Mikro- und Makroebene stelle ich meine und unsere zehn aktuellen und zukünftigen Forschungsschwerpunkte dar und verknüpfe sie mit meinen Lehrangeboten und der Anregung, ein neues Schwerpunktfach 'Empirische Wirtschafts- und Sozialforschung' an unserem Fachbereich einzurichten.

Assessment of income distribution and a hypothetical flat tax reform in Hungary

C80 - General
The paper presents evidence on the effects of taxes and benefits on household incomes in Hungary referring to the 2006 system and a hypothetical flat tax reform. For this, a microsimulation model is used, which is based on a matched sample of an income and a consumption survey and administrative tax records. The Hungarian budget receives more revenues from VAT than from PIT. This has major implications on equity, as while PIT is progressive, VAT is regressive, imposing a higher tax burden on low-income households. We highlight the importance of tax allowances. The absolute amount of total tax allowances tends to increase with income, and the share of allowances within total incomes is around 5-7% in all income groups, except the top fifth, where it declines. Targeting is thus inadequate, and it is especially so in case of child support. Family tax allowance reaches the bottom decile only to a limited extent. This is in sharp contrast with the universal child benefit, which is well targeted to the poorest. The second part explores the likely impact of the introduction of a flat tax, where VAT and PIT rates are set at 20%, and a tax free bracket for low incomes is kept. We show that a budget neutral solution would have a largely regressive effect, where 70% of the population would lose, with a minority on the top of the distribution gaining.

Methods for Scenario-building: it’s importance for policy analysis

C80 - General
A scenario is a policy analysis tool that describes a possible set of future conditions. The most useful scenarios (for corporations, for policy decision makers) are those that display the conditions of important variables over time. In this approach, the quantitative underpinning enriches the narrative evolution of conditions or evolution of the variables; narratives describe the important events and developments that shape the variables. In terms of innovative methods for policy analysis, the foresight and scenario building methods can be an interesting reference for social sciences. Some examples of these exercises will be present in this paper, either related to vision in science and technology developments, social and technological futures, or related to aggregated indicators on human development. Two cases (Japan and Germany) are held on behalf the ministries of science and education (respectively, MEXT and BMBF), and another with the support of United Nations.

This paper aims to provide a review on key methodological issues regarding two major international statistical approaches, which characterize the statistics on Child Labour, especially in poor countries. In the first section, we summarises and analyse some key concepts about the international definition on Child Labour. In the second section we analyze the methodology “Statistical Information and Monitoring Programme on Child Labour” (SIMPOC) by International Labour Organization (ILO). In the third section, we describe an alternative methodology promoted by World Bank (WB) identified through the “Living Standard Measurement Survey” (LSMS). In conclusion, in the fourth section, we briefly describe the Italian experience, reporting the major methodological implications emerged during the experimentation of the statistical research project “Children and Work” carried out in Italy by ISTAT (Italian National Institute of Statistics).

The paradigm of NPM, like its forerunners, has been trying to answer the same question for almost twenty years: how to implement policies, strategies, programs and projects, using the market-type mechanisms, so that the institutions of the state could achieve the desired results.
The praises and criticism that have accompanied this paradigm along its evolution are fully justified. Indeed, the NPM has strengths and weaknesses as well, and one purpose of this paper is to identify them and to find answers to the following questions.
Which components of the mechanism named NPM generate negative results? Why? What can be done? It is not easy to answer these questions, taking into consideration the multitude of factors influencing the public management, and especially the tremendous impacts of the accelerated process of globalization. The global problems of nowadays make any unilateral action of a government unconceivable, and this brings us to the concept of global public management (GPM). Nevertheless, the way forward will be the subject of another paper.
The paper is structured in two main sections, as follows:
The first section provides a conceptual framework, examining the multifaceted structure of the NPM and its mechanisms (the “state-of-the-art” of the “art of the state”).
The second section suggests a theoretical framework on “measuring” the aggregate attribute of the NPM – the QoG – illustrated by practical cases, in a twofold perspective: longitudinal (variation in time) and cross-sectional (variation among countries).

There is an ostensible relationship between whether or not a nation is developed and the interpretation and collection of data in this nation. For instance, if a country is developing, it is difficult to collect figures, though much simpler to interpret them. The opposite is the case in a developed nation: the gathering of data is undemanding, however, the explanation for this data is difficult. Such a relationship has a quite pressing effect on economic performance, and this will be examined using a model assuming Rational Expectations, Adaptive Expectations and certain postulates of Price Theory.

Revisiting the Derivative: Implications on the Rate of Change Analysis
Khumalo, Bhekuzulu
C53 - Forecasting and Prediction Methods ; Simulation Methods
C02 - Mathematical Methods
C80 - General
The aim of this paper is to raise concerns with the mathematical concept of the derivative as we know it. It raises concerns of accuracy. The paper is kept as simple as possible, solutions are always meant to be as simple as possible to be easily understood. The paper looks at linear and polynomial functions to illustrate that the derivative is not as precise as it should be, and in some instances can be considered almost a relic, though the solutions that are derived consider the simple derivative. It is the nature of polynomial functions that lead to the derivative not to be accurate and this paper clearly shows the shortcomings. The paper ends with a derivative that is accurate and precise, a derivative that when broken down is so simple. The main lesson/ conclusion is that it is all in the function, complex derivatives are not always necessary. This has important implications to all researchers, scientists who use the derivative to predict.

Fruitfulnes of contemporary companies rests on new business model development, elimination of communication obstacles, simplification of industrial processes, possibilities of responding in real-time and above all meeting the floating custom needs. Quite a number of company activities and transactions are realized within the framework of e-business. Business transactions are supported by e-commerce systems. One of the e-commerce system part is web interface (web sites). Present trend is putting the accent on security. E-commerce system security and web sites security is the most overlooked aspect of securing data. E-commerce system security depends on technologies and its correct exploitation and proceedings. If we want e-commerce system and e-shops web sites with all services to be safety, it is necessary to know all possible risks, use up to date technologies, follow conventions of web sites development and have good security management system. The article deals with definition and description of risk areas refer to e-commerce systems and e-shop web sites and show fundamental principles of e-commerce systems and e-shop web sites security.

At present, the world economy is at a cross road. The Nigerian economy is therefore undergoing it most severe economic crisis since the Biafra war of the sixties. Currently, she is experiencing a staggering rate of inflation (well up to the double digit) as well as experiencing a severe recession (as the unemployment rate has risen astronomically). Consequently, a basic thesis of this proposal is that stagflation has caused and will continue to cause considerable hardship for many Nigerian families and poses a serious threat to the mental health of a substantial proportion of the population. It is therefore the aim of this research to document in a systematic way how families that have experienced varying degrees of “inflation crunch” have adjusted to or tried to adapt to this pressure. In other words, this phased research project proposes to provide information that will be useful to policy makers (government) who must weigh the costs and benefits of the current inflationary pressures as well as severe recession. Essentially, the result will be an emergence and evolution of corrective policy measures and strategies (as adequate and functional).

It is the growing societal interest about the individual and its behaviour in our and 'modern'
societies which is asking for microanalyses about the individual situation. In order to allow
these microanalyses on a quantitative and empirically based level microsimulation models were
developed and increasingly used for economic and social policy impact analyses. Though
microsimulation is known and applied (mainly by experts), an easy to use and powerful PC
microsimulation model is hard to find.
The overall aim of this study and of MICSIM - A PC Microsimulation Model is to describe and
offer such a user-friendly and powerful general microsimulation model for (almost) any PC, to
support the impact microanalyses both in applied research and teaching. Above all, MICSIM is
a general microdata handler for a wide range of typical microanalysis requirements. This paper
presents the concept, developments and applications of MICSIM. After some brief remarks on
microsimulation characteristics in general, the concept and substantive domains of MICSIM: the
simulation, the adjustment and aging, and the evaluation of microdata, are described by its mode
of operation in principle. The realisations and developments of MICSIM then are portrayed by
the different versions of the computer program. Some MICSIM applications and experiences in
research and teaching are following with concluding remarks.

The possibilities of time use research approaches for the analysis of the use of media is the
focus of this study. After describing previous studies of media analyses time use research is
characterised and the particular suitability of its central surveying instruments – stylised
survey information and time use diaries – is investigated for media use analyses. The various
new surveying instruments will be newly systematized according to survey principles and
survey features/attributes and illustrated by numerous product examples. The critical
appraisal yields recommendations for a method mix of time use diaries and new technology
based surveying instruments.

Massively Parallel Computation Using Graphics Processors with Application to Optimal Experimentation in Dynamic Control
Mathur, Sudhanshu
Morozov, Sergei
C63 - Computational Techniques ; Simulation Modeling
C80 - General
The rapid increase in the performance of graphics hardware, coupled
with recent improvements in its programmability has lead to its adoption in many
non-graphics applications, including wide variety of scientific computing fields.
At the same time, a number of important dynamic optimal policy problems in economics
are athirst of computing power to help overcome dual curses of complexity
and dimensionality. We investigate if computational economics may benefit from
new tools on a case study of imperfect information dynamic programming problem
with learning and experimentation trade-off that is, a choice between controlling
the policy target and learning system parameters. Specifically, we use a
model of active learning and control of linear autoregression with unknown slope
that appeared in a variety of macroeconomic policy and other contexts. The endogeneity
of posterior beliefs makes the problem difficult in that the value function
need not be convex and policy function need not be continuous. This complication
makes the problem a suitable target for massively-parallel computation using
graphics processors. Our findings are cautiously optimistic in that new tools let
us easily achieve a factor of 15 performance gain relative to an implementation
targeting single-core processors and thus establish a better reference point on the
computational speed vs. coding complexity trade-off frontier. While further gains
and wider applicability may lie behind steep learning barrier, we argue that the
future of many computations belong to parallel algorithms anyway.

Contrary to claims by Gul and Pesendorfer (2008), I show that standard economics makes use of non-choice evidence in a meaningful way. This is because standard economics solely grounded in the theory of choice is "incomplete". That is, it has content that can not be revealed with any general choice procedure.

Das Problem der Spezifikation einer Konsumfunktion im Rahmen der VGR 2005
Quaas, Georg
C50 - General
E21 - Consumption ; Saving ; Wealth
C80 - General
In 2005, Germany’s national income accounting system was altered from fixed prices to previous year’s prices as basis for macroeconomic time series measured in real terms. Among other consequences, the new system offers a wider range of possibilities to interpret theoretically relevant variables empirically. Some of these different interpretations and specifications of both, the habit persistence hypothesis and an corresponding error correction model, are applied to the relationship between private consumption and income and estimated empirically. Compared to the estimators yielded in the framework of the former national account system with constant prices, the values of the marginal propensity to consume differ, but fall in the theoretically expected and by now empirically observed boundaries. Applying the theory of co-integration and a non-reduced error correction model lead to a slightly better explanation of the private consumption.

This paper revisits Grunfeld's well-known investment data, one of the most widely used data sets in all of applied econometrics, on the occasion of their
50th anniversary. It presents, apparently for the first time after the publication of the original Chicago Ph.D. thesis, the full data set, points out errors and inconsistencies in several currently available versions, and also revisits a number of empirical studies from the literature of the last five decades. Our findings provide a cautionary tale on the use of widely known data and underline the need for mandatory data and code archives.

This article describes the R package DEoptim which implements the differential evolution algorithm for the global optimization of a real-valued function of a real-valued parameter vector. The implementation of differential evolution in DEoptim interfaces with C code for efficiency. The utility of the package is illustrated via case studies in fitting a Parratt model for X-ray reflectometry data and a Markov-Switching Generalized
AutoRegressive Conditional Heteroskedasticity (MSGARCH) model for the returns of the Swiss Market Index.

Is inflation targeting preferred by Filipinos?

C80 - General
Analysis of World Values Survey 2000 data for the Philippines finds that lower income Filipinos are more likely than the upper income ones to support inflation targeting. The same can be said of older, healthier, and employed Filipinos but not of the educated and financially satisfied ones. Given the profile of people who preferred inflation targeting, the shift from monetary targeting to inflation targeting is deemed a pro-poor policy shift. Further analyses find that, in 2000, at least 53.1% of Filipino households preferred inflation targeting; in other words, the preference of Filipino society in 2000 was in line with the preference of the Bangko Sentral ng Pilipinas for inflation targeting.

The Interpretation of Unit Value Indices - Unit Value Indices as Proxies for Price Indices

C43 - Index Numbers and Aggregation

E01 - Measurement and Data on National Income and Product Accounts and Wealth ; Environmental Accounts
C80 - General
The unit value index (UVI) as compiled in Germany for exports and imports is compared with two other indices, viz. an index of Drobisch which unfortunately is likewise known as "unit value index" and the "normal" Laspeyres price index (PI) of exports and imports. The UVI may be viewed as a Paasche index compiled in two stages where unit values instead of prices are used in the low level aggregation stage. Unit values are average prices referring to an ag-gregate of (more or less homogeneous) commodities. The focus of the paper is on the decom-position of the discrepancy between UVIs and PIs (the "unit value bias") into a (well known) Laspeyres (or substitution) effect or "L-effect" and a structural component or "S-effect" due to substituting unit values for prices. It is shown that amount and sign of S depends on the corre-lation between the change of quantities of those goods that are included in the aggregate and their respective base period prices. By contrast to L the correlation between quantity and price movement is not relevant for S.

This study examined monthly KSE-100 index trading volume response to announcements about Consumer price index (CPI) in the period of January 2004 to august 2009. Regression results supported the hypothesis that change in CPI has significant association with the change in KSE 100 index trading volume and regression was statistically significant and has shown that there is a negative relationship between CPI “Consumer price index” and KSE-100 index trading volume. More over the Presence of endogeneity has also been discussed via applying heckman's correction in the data.

In this article results of the two experiments, aimed at the development of the instrument (test) that would enable construction of the comprehensive measure of individual overconfidence for the use in economic overconfidence experiments, are presented. Instrument was obtained in a two-stage procedure. In the first experimental phase, a pilot test, consisting of fifty general-knowledge questions of the unknown difficulty, was conducted to divide the items into three difficulty levels: hard, average-difficulty and easy questions. The second phase was aimed at verification of the replicability of results. Statistical tests supported the existence of the hard-easy effect, verified the success of categorization of questions into three levels of difficulty, and showed that gender was not associated with overconfidence in the developed instrument. The average group overconfidence measures obtained from both experimental phases did not differ from each other significantly. Instrument’s internal consistency was found to be good and acceptable for the use in social research. Compared to the tests used in the foregoing economic experiments, the obtained test is believed to result in the improvement of the overconfidence measurement quality.

TradeProd, the CEPII trade, production and bilateral protection database, provides an updated version of the worldwide data used in Mayer and Zignago (2005), and available on CEPII's website. The database contains three groups of information covering 28 industrial sectors in the ISIC (International Standard Industrial Classication) classication Revision 2. The first group is bilateral trade for the 1980-2004 period, based on BACI, one of the most exhaustive worldwide dataset publicly available. The second is an extension of industrial production figures from the Trade, Production and Protection database by Nicita and Olarreaga (2001). The third group is bilateral data on trade policy at the industry level (taris and NTBs) taken from TRAINS and from CEPII's MAcMap databasee, which both cover the 1989-2001 period.

ABSTRACT
This research paper focused on the corporate restructuring of Nippon Telegraph Telecommunication (NTT Group) under the pure holding company structure in 1999 and its
implications. In order to understand the holding company structure, we introduced the concept of "internal capital markets" and explained its application within the framework of NTT Group.
Next, we gave an account of the background events leading to NTT Group's corporate restructuring in order to understand the reason for choosing and keeping the
holding company structure. Our research methodologies include interviews with NTT Group's management and data from public sources.
Finally, to analyze the effect of the holding company structure to NTT Group, we conducted a hypothetical valuation analysis using the free cash flow model. Comparing the market value of NTT Group with our valuation results, it appeared that the market has undervalued NTT Group. We concluded our report with some suggestions on how NTT Group might be able to increase their market value.

This article describes the R package DEoptim which implements the differential evolution algorithm for the global optimization of a real-valued function of a real-valued parameter vector. The implementation of differential evolution in DEoptim interfaces with C code for efficiency. The utility of the package is illustrated via case studies in fitting a Parratt model for X-ray reflectometry data and a Markov-Switching Generalized
AutoRegressive Conditional Heteroskedasticity (MSGARCH) model for the returns of the Swiss Market Index.

This study examined monthly KSE-100 index trading volume response to announcements about Consumer price index (CPI) in the period of January 2004 to august 2009. Regression results supported the hypothesis that change in CPI has significant association with the change in KSE 100 index trading volume and regression was statistically significant and has shown that there is a negative relationship between CPI “Consumer price index” and KSE-100 index trading volume. More over the Presence of endogeneity has also been discussed via applying heckman's correction in the data.

Massively parallel computation using graphics processors with application to optimal experimentation in dynamic control
Morozov, Sergei
Mathur, Sudhanshu
C63 - Computational Techniques ; Simulation Modeling
C80 - General
The rapid growth in the performance of graphics hardware, coupled with recent improvements in its programmability has lead to its adoption in many non-graphics applications, including a wide variety of scientific computing fields. At the same time, a number of important dynamic optimal policy problems in economics are athirst of computing power to help overcome dual curses of complexity and dimensionality. We investigate if computational economics may benefit from new tools on a case study of imperfect information dynamic programming problem with learning and experimentation trade-off, that is, a choice between controlling the policy target and learning system parameters. Specifically, we use a model of active learning and control of a linear autoregression with the unknown slope that appeared in a variety of macroeconomic policy and other contexts. The endogeneity of posterior beliefs makes the problem difficult in that the value function need not be convex and the policy function need not be continuous. This complication makes the problem a suitable target for massively-parallel computation using graphics processors (GPUs). Our findings are cautiously optimistic in that new tools let us easily achieve a factor of 15 performance gain relative to an implementation targeting single-core processors. Further gains up to a factor of 26 are also achievable but lie behind a learning and experimentation barrier of their own. Drawing upon experience with CUDA programming architecture and GPUs provides general lessons on how to best exploit future trends in parallel computation in economics.

The effect of microaggregation on regression results: an application to Spanish innovation data
López, Alberto
O30 - General
C80 - General
Microaggregation is a technique for masking confidential data by aggregation. The aim of this paper is to analyze the extent to which microaggregated data can be used for rigorous empirical research. In doing this, I adopt an empirical perspective. I use data from the Technological Innovation Panel (PITEC) and compare regression results using both original and anonymized data. PITEC is a new firm-level panel data base for innovative activities of Spanish firms based on CIS data. I find that the microaggregation procedure used has a slight effect on the coefficient estimates and their estimated standard errors, especially when estimating linear models.

In this article results of the two experiments, aimed at the development of the instrument (test) that would enable construction of the comprehensive measure of individual overconfidence for the use in economic overconfidence experiments, are presented. Instrument was obtained in a two-stage procedure. In the first experimental phase, a pilot test, consisting of fifty general-knowledge questions of the unknown difficulty, was conducted to divide the items into three difficulty levels: hard, average-difficulty and easy questions. The second phase was aimed at verification of the replicability of results. Statistical tests supported the existence of the hard-easy effect, verified the success of categorization of questions into three levels of difficulty, and showed that gender was not associated with overconfidence in the developed instrument. The average group overconfidence measures obtained from both experimental phases did not differ from each other significantly. Instrument’s internal consistency was found to be good and acceptable for the use in social research. Compared to the tests used in the foregoing economic experiments, the obtained test is believed to result in the improvement of the overconfidence measurement quality.

We discuss the way of hoax spreading as gossip and rumor throughout the social media, i.e.: Twitter, by observing an empirical case in Indonesia. We discuss the spreading factor of the gossip in the social media and see the epidemiology of the propagation hoax before and after the hoax being clarified in the conventional mass media. The discussions brought us to the open enrchiment analysis of the sociology of gossip and rumors within the online services like Twitter for future observation of human behavior.

C80 - General
We document BACI, our international trade database covering more than 200 countries and 5,000 products,
between 1994 and 2006. Original procedures have been developed to reconcile data reported by almost
150 countries to the United Nations Statistics Division, which disseminate them via COMTRADE.
When both exporting and importing countries do report, we have two different figures for the same flow,
which is useful to reconcile in a single figure. Firstly, as import values are reported CIF (cost, insurance
and freight) and the exports are reported FOB (free on board), CIF costs have to be estimated and removed
from imports values to compute FOB import values. We regress the unit-values ratios reported
for a given elementary flow by gravity variables and for years, and world median unit-value for each
product category . The second step is an evaluation of the reliability of country reporting, based on the
reporting distances among partners. We decompose the absolute value of the ratios of mirror flows using
a (weighted) variance analysis, and an index is build for each country. These reporting qualities are used
as weights in the reconciliation of each bilateral trade flow twice reported. Taking advantage of this double
information on each flow, we end up with a large coverage of countries not reporting at a given level
of the product classification with a special care in the treatment of unit-values. BACI is freely available

Water reservoirs are large pools of water created stream or river catchment's areas and torrential rains and for storing water for use in many ways, and perhaps electric power generation is one of the most important uses of these reservoirs and for agriculture. That is extremely beneficial considering a rare and limited economic resources. Applied stochastic processes model has been applied in the work of Roseires dam, in order to develop a system to generate the highest possible power in the resources available. The current paper aims to apply another model, which is a dynamic programming model to verify the possibility of developing the same system and thus generate the highest possible electricity from the reservoir.
Data collected from the Ministry of Irrigation and the National Electricity Cooperation and international information network during the years 2006-2007.

This paper document the construction of BACI, our international trade database covering more than 200
countries and 5,000 products, between 1995 and 2004. Original procedures have been developed to reconcile
data reported by almost 150 countries to the United Nations Statistics Division, which disseminate them via
COMTRADE. When both exporting and importing countries do report, we have two different figures for the
same flow. In order to have a single coherent figure for each bilateral flow, we have need to reconcile them.
Firstly, as import values are reported CIF (cost, insurance and freight) and the exports are reported FOB (free
on board), CIF costs have to be estimated and removed from imports values to compute FOB import values.
We regress the unit-values ratios reported for a given elementary flow by gravity variables: bilateral distance,
dummies for adjacent or landlocked countries and for years, and world median unit-value for each product
category (we consider a non-linear relationship between CIF costs and distance by introducing also the square
distance). As expected, we find that CIF costs increase with distance and decrease with unit value. The second
step is an evaluation of the reliability of country reporting, based on the declaration distances among partners.
In order to evaluate this quality of countries reporting (as exporters or importers) we decompose the absolute
value of the ratios of mirror flows using a (weighted) variance analysis, and an index is build for every country.
Finally, the qualities of declaration are used as weights in the reconciliation of each bilateral trade flow twice
reported. Taking advantage of this double information on each flow, we end up en plus?? with a large coverage
of countries not reporting at a given level of the product classification. BACI provides the most disaggregated
international reconciled values of bilateral flows, for the largest possible number of countries and years, with a
special care in the treatment of unit-values. BACI is freely available to users of COMTRADE database in our

This dissertation takes on some important issues related with national accounts of Pakistan including (a) re-estimation of past series of national accounts (prior to the year 1999-00) to make it consistent with the new official series for years 1999-00 onward at new base year prices; (b) quarterisation of annual series of national accounts to remove one of the major stumbling block in research by making available high frequency data, (c) estimation of provincial accounts with new base year prices, and (d) estimation the contribution of total factor productivity (TFP) to economic growth with the new series of gross domestic product and its sub-sectors.
Thus by embarking upon the above mentioned issues, the dissertation contributes to the economic literature in the following respects:
• It provides a new set of national accounts at 1999-00 prices as well as at current prices for a period from 1970-71 to date consistent with the new official estimates for recent years.
• It gives quarterly data of GDP and all its sectors/sub-sectors both at constant prices of 1999-00 and at current prices.1 A by-product of this exercise is quarterly GDP deflator (with 1999-00=100) which was earlier not available in Pakistan.
• It presents estimates of provincial GDP and all its sectors/sub-sectors covering all the provinces in a consistent framework.2
• It provides series of gross fixed capital formation and capital stock estimated at disaggregated level and at prices of 1999-00.
• It estimates contribution of TFP, capital and labour to the growth of GDP and its sectors/sub-sectors (growth rates of new series at 1999-00 prices).

BACI draws on United Nations COMTRADE data and covers more than 200 countries and 5,000 products, between 1994 and 2004. Imports and exports flows are reported annually by 130 countries to United Nations in values and quantities. When both exporting and importing countries report, we have two figures for the same flow, which have to be harmonised given the huge discrepancies between them: at the 6-digit level of the Harmonised System, the gap between mirror declarations exceeds 100 % for half of the observations in COMTRADE. Original procedures are developed aiming at providing the more disaggregated and rigorous trade database for the largest possible number of countries and years, with a special care in the treatment of unit values.

This paper comes in two parts, this being the first. Part 1 is not a research paper in the sense of the Scientific Method; it is rather unsophisticated data mining - a cheap data mining exercise for that matter, because it does not follow any received economic, or other, theory. In the sense of Ed E. Leamer, it is “data without theory,” and data without theory does not speak for itself, despite the common cliché of “letting the data speak for itself.” The objective here is to adjust the money value of the Nobel Prize to include the values of the Nobel Prize medal and diploma. It is an arithmetic exercise that reveals that Alfred Nobel’s monetary contribution to humanity is huge. More importantly, the calculations generate data that make it possible to focus on the economic implications of Nobel’s bequest for human capital accumulation, technological progress, and long-run economic growth, which are subjects of a separate effort in Part 2. In this “paper” I indicate some basic relationships among and between key variables in Section 4, and remark in the last section that the Nobel Prize is a massive contribution, even without taking into account the time value of money. For instance, the unadjusted value of the Economics Nobel Prize in 1969 awarded to Ragnar Frisch and Jan Tinbergen was only 2.92 million SEK (US$0.57 million), but adjusted for the medal and diploma values the award was 5.85 million SEK (US$1.14 million).

[This paper seeks to measure the magnitude of inter temporal and spatial variations in the prices of flower crop between same type of marketing institutions as well as different types of marketing institutions and to assess the competitiveness and efficiency of marketing in the rural and urban trade markets of flower crops in West Bengal in Indian context where female act as important marketing agents. This study suggests that trade market for most of flower crops are not efficient in the area we studied. However, price per unit for all flower crops is lower in village level markets, and female marketing agents offer lower price for all flower crops in all types of markets. Also, the marketing efficiency for some flower crops is somewhat higher for female marketing agents

C80 - General
In this article results of the two experiments, aimed at the development of the instrument (test) that would enable construction of the comprehensive measure of individual overconfidence for the use in economic overconfidence experiments, are presented. Instrument was obtained in a two-stage procedure. In the first experimental phase, a pilot test, consisting of fifty general-knowledge questions of the unknown difficulty, was conducted to divide the items into three difficulty levels: hard, average-difficulty and easy questions. The second phase was aimed at verification of the replicability of results. Statistical tests supported the existence of the hard-easy effect, verified the success of categorization of questions into three levels of difficulty, and showed that gender was not associated with overconfidence in the developed instrument. The average group overconfidence measures obtained from both experimental phases did not differ from each other significantly. Instrument’s internal consistency was found to be good and acceptable for the use in social research. Compared to the tests used in the foregoing economic experiments, the obtained test is believed to result in the improvement of the overconfidence measurement quality.

The correlation between air pollution and health effects in large Japanese cities presents a great challenge owing to the limited availability of data on the exposure to pollution, health effects and the uncertainty of mixed causes. A methodology for quantitative relationships (between the emission volume and air quality, and the air quality and health effects) is analysed with a statistical method in this article; the correlation of air pollution reduction policy in Japan from 1974 to 2007.
This chapter discusses a step-by-step methodology of determining the direct correlation between emission volumes, air quality, and health effects.
The relationship between total emissions (NOx, PM) (from both stationary and mobile sources) and air quality (NO2, TSP) was found to be significant. The correlation analysis of emission volume, and air quality suggests that NOx and PM levels worsen according to increases in NO2.
When the correlation between the air pollutant and the type of health effect (certified, mortality, recovery, and newly registered) was examined according to the certified area, an inverse relationship was observed. The relationship between air quality (NO2) and health effect was found to be significant. When NO2 worsens, certified patients, mortality rates and newly certified patients increase, according to the data from 1989 to 2007 with dummy variable analysis.

In this paper, we used the production function method and the Van Norden method to estimate China's output gap (and potential output) from 1985 to 2009 year,and comparise the two methods. The results showed that: (1) the results of different methods are basically consistent with our economic situation. (2) Chinese economic stability enhanced after the emergence of sharp fluctuations, so development of domestic demand is the only way to stabilize the economy. (3) the results estimated by the Van Norden are more sensitive than PF method's . (4) From 2000, the potential output of China has increased.

The new CFS Divisia monetary aggregates: design, construction, and data sources

The Center for Financial Stability (CFS) has initiated a new Divisia monetary aggregates database, maintained within the CFS program called Advances in Monetary and Financial Measurement (AMFM). The Director of the program is William A. Barnett, who is the originator of Divisia monetary aggregation and more broadly of the associated field of aggregation-theoretic monetary aggregation. The international section of the AMFM web site is a centralized source for Divisia monetary aggregates data and research for over 40 countries throughout the world. The components of the CFS Divisia monetary aggregates for the United States reflect closely those of the current and former simple-sum monetary aggregates provided by the Federal Reserve. The first five levels, M1, M2, M2M, MZM, and ALL, are composed of currency, deposit accounts, and money market accounts. The liquid asset extensions to M3, M4-, and M4 resemble in spirit the now discontinued M3 and L aggregates, including repurchase agreements, large denomination time deposits, commercial paper, and Treasury bills. When the Federal Reserve discontinued publishing M3 and L, the Fed stopped providing the consolidated, seasonally adjusted components. Also the Fed no longer provides the interest rates on the components. With so much of the needed component quantity and interest-rate data no longer available from the Federal Reserve, decisions about data sources needed in construction of the CFS aggregates have been far from easy and sometimes required regression interpolation. This paper documents the decisions of the CFS regarding United States data sources at the present time, with particular emphasis on Divisia M3 and M4.

An important issue in fitting stochastic models to electricity spot prices is the estimation of a component to deal with trends and seasonality in the data. Unfortunately, estimation routines for the long-term and short-term seasonal pattern are usually quite sensitive to extreme observations, known as electricity price spikes. Improved robustness of the model can be achieved by (a) filtering the data with some reasonable procedure for outlier detection, and then (b) using estimation and testing procedures on the filtered data. In this paper we examine the effects of different treatment of extreme observations on model estimation and on determining the number of spikes (outliers). In particular we compare results for the estimation of the seasonal and stochastic components of electricity spot prices using either the original or filtered data. We find significant evidence for a superior estimation of both the seasonal short-term and long-term components when the data have been treated carefully for outliers. Overall, our findings point out the substantial impact the treatment of extreme observations may have on these issues and, therefore, also on the pricing of electricity derivatives like futures and option contracts. An added value of our study is the ranking of different filtering techniques used in the energy economics literature, suggesting which methods could be and which should not be used for spike identification.

The development of a reliable procedure for the aggregation of individual level happiness leads to a proper understanding of group level happiness. Such a procedure is indispensable for a more responsive public policy-making. However, individual self-reports on happiness must meet the dual requirements of cardinality and relative interpersonal comparability in order that aggregation is not problematic and the resulting measure not only makes sense but also useful for group level interventions. The paper demonstrates the procedure for obtaining group level happiness using data from the Philippines.

Earlier research found no difference in the happiness between a housewife and a working wife. However, there now is the expectation that a difference in their happiness exists today given the increase in the labor participation of women over the years. This paper revisits the debate using data from the 2000s. For the upper- and low-income economies, there is still no difference in the happiness between a housewife and a working wife. In contrast, results for the middle-income economies clearly show that a part-time working wife is happier than a housewife and that both part-time working wife and housewife are happier than a full-time working wife.

e-Government structures permits the government to
operate in a more transparent and accountable manner of which it
increases the power of the individual in relation to that of the
government. This paper identifies the factors that determine
customer’s attitude towards e-Government services using a
theoretical model based on the Technology Acceptance Model. Data
relating to the constructs were collected from 200 respondents. The
research model was tested using Structural Equation Modeling
(SEM) techniques via the Analysis of Moment Structure (AMOS 16)
computer software. SEM is a comprehensive approach to testing
hypotheses about relations among observed and latent variables. The
proposed model fits the data well. The results demonstrated that e-
Government services acceptance can be explained in terms of
compatibility and attitude towards e-Government services. The setup
of the e-Government services will be compatible with the way users
work and are more likely to adopt e-Government services owing to
their familiarity with the Internet for various official, personal, and
recreational uses. In addition, managerial implications for
government policy makers, government agencies, and system
developers are also discussed.

World Database of happiness: Example of a focused ‘Findings Archive’

C80 - General
Social scientists are producing an ever growing stream of research findings, which is ever more difficult to oversee. As a result, capitalization on earlier investment declines
and accumulation of knowledge stagnates. This situation calls for more research synthesis and interest in synthetic techniques is on the rise.
To date attention has been focused on techniques for meta-analysis, with little attention paid to the preliminary step of bringing the available research findings together. What we need is 1) techniques for describing research findings in a comparable way, 2) a system for storing such descriptions in an easily accessible archive, 3) to which research findings can be added on a continuous basis.
The World Database of Happiness is an example of such a tool. The archive is tailored to meet the requirements of assembling research findings on happiness; both
distributional findings (how happy people are) and correlational findings (what things go together with happiness).
With its focus on 'findings' the system differs from data-archives that store 'investigations' and from bibliographies that store 'publications'. As yet there is no established term to describe this tool for research synthesis. I call it a 'focused findings archive'. In this paper I describe how that works and discusses the strengths and weaknesses of this approach.

Marine and coastal ecosystems are of high importance owing to the mankind dependence on the goods and services provided. As water quality is one perspective of healthy marine and coastal ecosystems, the aim of this study is to review as more as possible surveys conducted worldwide and in Greece. Due to the lack of an official market to valuate non-marketed goods and services, contingent valuation is applied intensively in order to provide the policy makers and the society generally with the specific values derived by a developed hypothetical market. In addition, this study reviews the crucial but debatable notion of value, the theoretical framework in accordance with the existing statistical models to estimate the welfare measures and the numerous disadvantages that have to be taken into account in order to implement a reliable contingent valuation survey.

IT industry has shown phenomenal growth in the city of Bangalore which has changed the very nature of the city. Large migration to the city also has created several environmental problems. Because of growth of this industry in selected pockets income inequality in the state is also on the rise which have many adverse social implications. But the sector has been able to generate significant employment and this role needs to be highlighted as educated unemployment can create many adverse economic and social problems as well. Further the rise of the industry has enhanced income of the state of Karnataka and export from this sector helps country to improve India’s balance of payment scenario. This paper examines the status and impact of IT industry in Bangalore and compares the city with other major locations within India.

Nature and Dimensions of Farmers’ Indebtedness in India

C80 - General
This paper examines nature and extent of farmers’ indebtedness in India using unit record data from NSSO 59th round, and provided a comparative picture of major Indian states. It shows using data from rice cultivating farmers that productivity of small farmers is not only higher than the medium farmers, it increases with access to credit. In terms of access to credit, seen through extent of indebtedness, Karnataka is better placed than many Indian states. But Andhra Pradesh, Tamil Nadu, Punjab and Kerala lie ahead of Karnataka. Ironically however, almost half of the credit is still provided by the informal sector in the state of Karnataka (on an average). Region wise picture shows that Southern region is more dependent on informal sources of credit. Poor farmers with lower land holdings are much more deprived of the formal sources of credit than the comparatively richer ones. Thus they also pay a much higher rate of interest with modal value of 36%. But it is heartening to note that loans are taken mostly for income generating purposes. It also indirectly implies that even for the income generating purposes poor are not getting access to formal sources of credit.

C80 - General
In this article results of the two experiments, aimed at the development of the instrument (test) that would enable construction of the comprehensive measure of individual overconfidence for the use in economic overconfidence experiments, are presented. Instrument was obtained in a two-stage procedure. In the first experimental phase, a pilot test, consisting of fifty general-knowledge questions of the unknown difficulty, was conducted to divide the items into three difficulty levels: hard, average-difficulty and easy questions. The second phase was aimed at verification of the replicability of results. Statistical tests supported the existence of the hard-easy effect, verified the success of categorization of questions into three levels of difficulty, and showed that gender was not associated with overconfidence in the developed instrument. The average group overconfidence measures obtained from both experimental phases did not differ from each other significantly. Instrument’s internal consistency was found to be good and acceptable for the use in social research. Compared to the tests used in the foregoing economic experiments, the obtained test is believed to result in the improvement of the overconfidence measurement quality.

Robust estimation and forecasting of the long-term seasonal component of electricity spot prices

C45 - Neural Networks and Related Topics
Q47 - Energy Forecasting
C80 - General
When building stochastic models for electricity spot prices the problem of uttermost importance is the estimation and consequent forecasting of a component to deal with trends and seasonality in the data. While the short-term seasonal components (daily, weekly) are more regular and less important for valuation of typical power derivatives, the long-term seasonal components (LTSC; seasonal, annual) are much more difficult to tackle. Surprisingly, in many academic papers dealing with electricity spot price modeling the importance of the seasonal decomposition is neglected and the problem of forecasting it is not considered. With this paper we want to fill the gap and present a thorough study on estimation and forecasting of the LTSC of electricity spot prices. We consider a battery of models based on Fourier or wavelet decomposition combined with linear or exponential decay. We find that all considered wavelet-based models are significantly better in terms of forecasting spot prices up to a year ahead than all considered sine-based models. This result questions the validity and usefulness of stochastic models of spot electricity prices built on sinusoidal long-term seasonal components.

Constructing weekly returns based on daily stock market data: A puzzle for empirical research?

The weekly returns of equities are commonly used in the empirical research to avoid the non-synchronicity of daily data. An empirical analysis is used to show that the statistical properties of a weekly stock returns series strongly depend on the method used to construct this series. Three types of weekly returns construction are considered: (i) Wednesday-to-Wednesday, (ii) Friday-to-Friday, and (iii) averaging daily observations within the corresponding week. Considerable distinctions are found between these procedures using data from the S&P500 and DAX stock market indices. Differences occurred in the unit-root tests, identified volatility breaks, unconditional correlations, ARMA-GARCH and DCC MV-GARCH models as well. Our findings provide evidence that the method employed for constructing weekly stock returns can have a decisive effect on the outcomes of empirical studies.

Monthly economic indicators are used for a variety of purposes, from studying business cycles to determining economic policy and making informed business decisions. China’s published monthly industrial output statistics could hardly be more confusing, with changes in variables, in coverage, in measurement, and in presentation. This paper reviews the available official data and proceeds to construct a monthly industrial output series in nominal terms and in real terms for the period since May 1983, economy-wide and for the state sector.

This article illustrates the difficulties of quantifying overconfidence in economic experiments and suggests a procedure for the development of the reliable overconfidence measurement instrument (test). Following the suggested two-stage procedure a sample measure of overconfidence is developed. First a pilot test is conducted to divide the initial fifty items into three difficulty levels: hard, moderate and easy questions. A final test was compiled of six questions of each difficulty levels. In the second phase a replicability check was run with the final instrument.

The paper presents a general empirical method of distance-based multifaceted systematic identifying
of the positions of countries in relation to inequalities and imbalances. In order to understand the world economic relations in their entirety, we decided to analyze twelve most populous countries and eleven macroeconomic, environmental and demographic indicators relevant to them. Our analysis covering the period 1992-2008 attempts to identify core parts of the global economic system and countries that pose a potential risk of instability.

One can compare Econometrics with an Art which tries to minimize the lag between a quantitative law and a sample of data. Hence, the econometrics teaches us that before to built models, we must built data bank through strict procedures to prevent errors. Our paper presents classical methods to check data bank building and data computing, then we present new encoding methods ("Explicit Sizes Mantissa", "Dual Mantissa", and "Cumulated Indexes Mantissa") which can lead to follow the data through computing. Some can be based on the Information Theory.

This research advances the understanding of people’s attitude towards water resources valuation. Specifically, it aims to improve confidence in the interpretation of people’s willingness to pay (WTP) for water resources protection by enhancing understanding of value relationships. Primary data were obtained from a sample of 510 people living in and visiting the Pinios River in the eastern part of Central Greece. Respondents’ behavior was explored by measuring and comparing use and non-use values with the help of a proposed constructed scale for measuring the dimensions of Total Economic Value of a water resource. For this purpose, a combination of applied methodological research techniques like Principal Component and Cluster Analyses together with logistic regression was used. The results indicated the relative importance of particular value components in determining water resources conservation preferences, as well as individuals’ WTP for protecting them. We have extracted four factors and explored their influence on respondents’ WTP and the general attitude towards the area. There were high associations between WTP of individuals towards river protection in relation to their characteristics (like education, income and origin).

Queue Dissipation Shockwave Speed for Signalized Intersections
Omid, M. Rouhani

C83 - Survey Methods ; Sampling Methods
Z0 - General
Queue formation and dissipation have been extensively studied in relation to traffic signalization, work zone operation, incident occurrence, and ramp metering. This study is an attempt to estimate the effect of vehicle mix, commute time, traffic direction, and road upgrade on queue dissipation speed (time). The data were collected at several intersections in Davis, California, U.S. and analyzed using regression models. The models were determined regressing several functional forms and considering the statistical significance and ease of interpretation of the included variables. The main findings are: 1) dissipation speed does not vary purely by location; 2) a heavy vehicle is faster to discharge than its passenger car size-equivalent is; 3) the queue in a left-turn lane discharges faster than that in a through lane; 4) an upgrade slope increases the queue dissipation time due to more rolling resistance to vehicle start-up and larger vehicle gaps for safety ; 5) morning queues generally discharge more slowly; 6) contrary to common delay estimation models, regression analysis shows that queue dissipation time is linearly related to the number of vehicles rather than quadratically or in other ways; and 7) the simple linear function performs well both in terms of explanatory power (R2) and consistency of signs.

Data processes run by states, governments and the like have been a great deal and as old as the modern human history. Data had always been important. Tons were collected and siloed, but never in the past had its importance been felt as much as it had been when the last crisis broke out in 2008. Because these tons of data either, as some were redundant and occupying large spaces with huge storage costs, were not useful given the processing power and due to outdated mind-sets, or were not even the tiniest portion of the data necessary to do analysis , the experts realised. With the advances in the digital world dealing with data has become easier. Combined with the urgent needs and demands from the bottom up and top down there now is more enlightened and educated perception of data and whatever its extensions are, and its / their potential use, though a little bit late. In the late 90s, however, things were not as computerised and DataeXve was not as Big as it is today, and manual operations dominated the automated ones. There were definitely inefficiencies in DataeXve. Still, even then, there were efforts to improve these processes. This work focuses on one of those early efforts.

This study proposes a comparative analysis at regional level, of concentration level of expenditure co-financed by the Structural Funds in the programming period 2007/13. For main types of expenditure, we evaluate by the concentration index of Herfindahl-Hirschman the level of concentration of projects. It is verified also the relationship between it and some background variables. The analysis shows that the average funding of the projects financed is greater in the South than in the Centre-North. In the case of concentration level of the contributions to the firms, the analysis shows that interventions are correlated directly with the number of firms in the area, this is an interesting result only apparently counterintuitive.

On the Sources of Heterogeneity in Banking Efficiency Literature

One learns two main lessons from studying the great quantity of banking efficiency literature. These lessons regard the heterogeneity in results and the absence of a comprehensive review aimed at understanding the reasons for this variability. Surprisingly, although this issue is well-known, it has not been systematically analyzed before. In order to fill this gap, we perform a Meta-Regression-Analysis (MRA) by examining 1,661 efficiency scores retrieved from 120 papers published over the period 2000-2014. The meta-regression is estimated by using the Random Effects Multilevel Model (REML), because it controls for within-study and between-study heterogeneity. The analysis yields four main results. Firstly, parametric methods yield lower levels of banking efficiency than nonparametric studies. This holds true even after controlling for the approach used in selecting the inputs and outputs of the frontier. Secondly, we show that banking efficiency is highest when using the value added approach, followed by estimates from studies based on the intermediation method, whereas those based on the hybrid approach are the lowest. Thirdly, efficiency scores also depend on the quality of studies and on the number of observations and variables used in the primary papers. As far as the effects of sample size, dimension and quality of papers are concerned, there are significant differences in sign and magnitude between parametric and nonparametric studies. Finally, cost efficiency is found to be higher than profit and production efficiency. Interestingly, MRA results are robust to the potential outliers in efficiency and sample size distributions

This paper presents results concerning the nonlinear analysis of the mean annual value temperature time series corresponding to the Earth’s global climate for the time period of 713 – 2004. The nonlinear analysis consists of the application of several filtering methods, the estimation of geometrical and dynamical characteristics in the reconstructed phase space, techniques of discrimination between nonlinear low dimensional and linear high dimensional (stochastic) dynamics and tests for serial dependence and nonlinear structure. All study results converge to the conclusion of nonlinear stochastic and complex nature of the global earth climate.

An Analysis on Economic Opportunity
Li, Kui-Wai
C80 - General
O11 - Macroeconomic Analyses of Economic Development
Although economic opportunity is considered as a latent variable, it can serve as another factor in promoting growth and development. Through the construction of an economic opportunity index, this paper identifies the extensity and intensity channels through which economic opportunity are created. Data on 24 variables for 184 world economies for the period 2000-2010 are collected for the empirical analysis. The methodology involves the use of principle component analysis in constructing three indices for the parametric and non-parametric regression analyses. The country sample is divided into OECD and non-OECD economies so as to examine their different performance. Extensity seems to be the more important channel to all economies, but for non-OECD economies, a higher performance in intensity can enrich the effect of extensity on economic opportunity.

The volume of work on productivity effects of research and development (R&D) investment has expanded significantly following the contributions of Zvi Griliches and others to microeconometric work in late 1970s and early 1980s. This study aims to meta-analyse the research findings based on OECD firm and industry data, with a view to establish where the balance of the evidence lies and what factors may explain the variation in reported evidence. Drawing on 1,262 estimates from 64 primary studies, we report that the average effect of R&D capital on productivity and the average rate of return on R&D investment are both positive, but smaller than the summary measures reported in previous narrative reviews and meta-analysis studies. We also report that a range of moderating factors have significant effects on the variation among productivity and rates-of-return estimates reported in primary studies. Moderating factors with significant effects include: (i) measurement of inputs and output; (ii) model specifications; (iii) estimation methods; (iv) levels of analysis; (v) countries covered; and (vi) publication type among others.

This paper is prepared against the broader background of the policy debates on the breeding, feeding and distributional consequences of dairy development in India. The data for the study is drawn from the National Dairy Sample Survey covering 186 districts spread over 14 major States in the Country. Analysis presented in the paper shows that the diffusion and adoption of crossbreeding technology is an important factor contributing to the level, pattern, and sources of milk production. There is no evidence to show that the increase in milk production and widespread adoption of crossbreeding technology resulted in the intensification of the pressure on land resources for the production of livestock feed. The production of milk is carried out largely by the weaker sections of the rural society. Since agriculture is rapidly getting mechanized, draught power requirement would not work as a constraint on the diffusion and adoption of new breeds of milch animals. Drawing on the main findings, the paper offers a number of recommendations for the consolidation and acceleration of milk production and the sustainable income generation for the rural poor.

Inadequate waste management leads to many environmental issues and the adoption of an efficient and sustainable waste management has become a priority objective of the EU. However, besides the demographic factors, the various socio-economic and geographical conditions of this complex space lead to major disparities in municipal waste management between North and South, East and West. This paper aims to do a spatial-temporal analysis of the Eurostat indicators using ascending hierarchical cluster analysis that divides the member states into five typological classes. The resulted maps highlight territorial disparities among Member States on municipal waste management and also reveal the evolution of environmental policies between 2003-2009 related to the EU acquis.

Measuring economic uncertainty using news-media textual data
Peter, Eckley
C80 - General

E66 - General Outlook and Conditions
G10 - General
We develop a news-media textual measure of aggregate economic uncertainty, defined as the fraction of Financial Times articles that contain uncertainty-related keyphrases, at frequencies from daily to annual, from January 1982 to April 2014.
We improve on existing similar measures in several ways. First, we reveal extensive and irregular duplication of articles in the news database most widely used in the literature, and provide a simple but effective de-duplication algorithm. Second, we boost the uncertainty ‘signal strength’ by 14% through the simple addition of the word “uncertainties” to the conventional keyword list of “uncertain” and “uncertainty”, and show that adding further uncertainty-related keyphrases would likely constitute only a second-order adjustment. Third, we demonstrate the importance of normalising article counts by total news volume and provide the first textual uncertainty measure to do so for the UK.
We empirically establish the plausibility of our measure as an uncertainty proxy through a detailed narrative analysis and a detailed comparative analysis with another popular uncertainty proxy, stock returns volatility. We show the relationship between these proxies is strong and significant on average, but breaks down periodically. We offer plausible explanations for this behaviour. We also establish the absence of Granger causation between the measures, even down to daily (publication) frequency.

New regulation of EU cohesion policy prescribes ex ante impact eval- uations. These imply a vision of the working of a process of economic change. A theory of change based on the concept of equilibrium (which is a situation in which by definition change is not liable to occur) being paradoxical, the present article aims at presenting bases and basics of Amendola’s out-of-equilibrium approach in a perspective that is instru- mental in the above-referred concrete policy issue. Accordingly, after reviewing the essentials of John Hicks’ concern with the construction of an out-of-equilibrium approach, the key concepts at play in Amendola and Gaffard’s out-of-equilibrium model are summarized and, after considering the resulting perspective on policy making, and touching on EU o�cial framework for institutional accounts, the sequence of ac- counts implicit in the out-of-equilibrium model is eventually derived.

In this paper, we try to measure the semi-strong efficiency of the sports betting market. In particular, we aim to understand whether the efficiency of the market is realized in the case of fixed odds provided by bookmakers on the four major European football championships. By examining the trends of odds in the event of some major change in expectations about the teams’ results, i.e. when a team’s coach is replaced, we attempt to verify the argument that a profitable betting strategy for the bettor is likely possible. In this case, the market that we are taking into account will be inefficient.

One learns two main lessons from studying the great quantity of banking efficiency literature. These lessons regard the heterogeneity in results and the absence of a comprehensive review aimed at understanding the reasons for this variability. Surprisingly, although this issue is well-known, it has not been systematically analyzed before. In order to fill this gap, we perform a Meta-Regression-Analysis (MRA) by examining 1,661 efficiency scores retrieved from 120 papers published over the period 2000-2014. The meta-regression is estimated by using the Random Effects Multilevel Model (REML), because it controls for within-study and between-study heterogeneity. The analysis yields four main results. Firstly, parametric methods yield lower levels of banking efficiency than nonparametric studies. This holds true even after controlling for the approach used in selecting the inputs and outputs of the frontier. Secondly, we show that banking efficiency is highest when using the value added approach, followed by estimates from studies based on the intermediation method, whereas those based on the hybrid approach are the lowest. Thirdly, efficiency scores also depend on the quality of studies and on the number of observations and variables used in the primary papers. As far as the effects of sample size, dimension and quality of papers are concerned, there are significant differences in sign and magnitude between parametric and nonparametric studies. Finally, cost efficiency is found to be higher than profit and production efficiency. Interestingly, MRA results are robust to the potential outliers in efficiency and sample size distributions

This study reviews the empirical literature on banking efficiency by conducting a meta-regression analysis. The metadata-set consists of 1,661 observations retrieved from 120 papers published over the period 2000-2014. While the role of study-design and method-specific characteristics of primary studies is evaluated, a focus concerns regulation in banking. Results are fourfold. Firstly, parametric methods always yield lower levels of banking efficiency than nonparametric studies. Secondly, banking efficiency is high in studies using the value added approach instead of the intermediation method. Thirdly, efficiency scores also depend on the ranking journals and on the number of observations and variables used in the primary papers. Finally regulation matters: primary papers focusing on countries with a liberalized banking industry provide high values of efficiency scores.

Measuring economic uncertainty using news-media textual data

E66 - General Outlook and Conditions
G10 - General
We develop a news-media textual measure of aggregate economic uncertainty – the fraction of Financial Times articles containing uncertainty-related keyphrases – for 1982–2014 at daily to annual frequencies. We contribute to the literature in three areas.
First, we provide a measurement framework that links observed expressions of uncertainty in newspaper articles to a latent propensity to express uncertainty, which we argue is an ordinal proxy for the uncertainty that matters for economic decision-making, namely the intensity of the cognitive state of uncertainty. We use this framework to estimate how the noise-to-signal ratios varies with sample size (or frequency) and show that noise variance is modest at monthly and lower frequencies, and approaching signal variance at daily frequency.
Second, we study key choices in the empirical implementation of such measures more deeply than has been done previously, focusing on uncertainty keyphrase selection, isolating economic uncertainty, de-duplication of articles, and appropriate scaling of the uncertainty measure, with a critique of scaling methods commonly used in the literature. Our findings provide empirical foundations for the extant literature, and evidence-based recommendations for methodological improvements.
Third, we conduct the first detailed comparative analysis of a news-media uncertainty measure with another uncertainty proxy, stock returns volatility. Our narrative analysis establishes the plausibility of our news-media measure. Our quantitative analysis reveals a strong relationship to stock volatility on average. But this relationship breaks down periodically, with timing that suggests that the semantics of the word “uncertainty” may be biased towards downside uncertainty or risk. Finally, we establish the absence of Granger causation between the measures down to daily frequency, except for a one-day lead of stock volatility over news-media uncertainty, which is to be expected given that the FT is published before the market opens.

The effect of technological innovation on employment is of major concern for workers and their unions, policy-makers and academic researchers. We aim to provide a quantitative synthesis of the evidence base and the extent of heterogeneity therein. Analysing 567 estimates from 35 primary studies that estimate a derived labour demand model we report the following findings: (i) the effect on employment is positive but small and highly heterogeneous; (ii) publication selection bias reflects a tendency to support the twin hypotheses that process innovation is associated with job destruction whereas product innovation is associated with job creation; (iii) the effects of process and product innovations do not conform to theoretical predictions or narrative review findings after selection bias is controlled for; (iv) only a small part of the residual heterogeneity is explained by moderating factors; (v) country-specific effect-size estimates are related to labour-market and product-market regulation in six OECD countries in a U-shaped fashion; and (vi) OLS estimates reflect upward bias whereas those based on time-differenced or within estimators reflect a downward bias. Our findings bridge the evidence gap in the research field and point out to data quality and modeling issues that should be considered in future research.

Data processes run by states, governments and the like have been a great deal and as old as the modern human history. Data had always been important. Tons were collected and siloed, but never in the past had its importance been felt as much as it had been when the last crisis broke out in 2008. Because these tons of data either, as some were redundant and occupying large spaces with huge storage costs, were not useful given the processing power and due to outdated mind-sets, or were not even the tiniest portion of the data necessary to do analysis , the experts realised.
With the advances in the digital world dealing with data has become easier. Combined with the urgent needs and demands from the bottom up and top down there now is more enlightened and educated perception of data and whatever its extensions are, and its / their potential use, though a little bit late. In the late 90s, however, things were not as computerised and DataeXve (DataExhaustive ) was not as Big as it is today, and manual operations dominated the automated ones. There were definitely inefficiencies in DataeXve. Still, even then, there were attempts to improve these processes.
This work focuses on one of those early attempts, in an effort to give a conceptual framework of how data management by public institutions can be handled by centralising rather than sharing the sparse individual databases throughout a national data system by visiting an almost two decade old design.

Възможности за използване на протокол HTTP/2 за намаляване на лага при зареждане на уеб приложения
Petrov, Pavel
Petrova, Stefka
C80 - General
This article examines the evolution of the protocol HTTP - from version 0.9 through 1.0, and 1.1 to version 2. The factors affecting latency and lag when loading web pages are discussed in details. The research concludes that nowadays network bandwidth plays an increasingly small role about the lag. The results of empirical research how much the lag is reduced when using HTTP/2 while loading an average by volume and by content web page are presented. In the tests are used different versions of the protocol HTTP - HTTP/1.0, HTTP/1.1, HTTPS/1.1 and HTTPS/2. An experimental software is created and an external program to simulate network latency is used.
