Distribution-Preserving Statistical Disclosure Limitation

One approach to limiting disclosure risk in public-use microdata is to release multiply-imputed, partially synthetic data sets. These are data on actual respondents, but with confidential data replaced by multiply-imputed synthetic values. A mis-specified imputation model can invalidate inferences because the distribution of synthetic data is completely determined by the model used to generate them. We present two practical methods of generating synthetic values when the imputer has only limited information about the true data generating process. One is applicable when the true likelihood is known up to a monotone transformation. The second requires only limited knowledge of the true likelihood, but nevertheless preserves the conditional distribution of the confidential data, up to sampling error, on arbitrary subdomains. Our method maximizes data utility and minimizes incremental disclosure risk up to posterior uncertainty in the imputation model and sampling error in the estimated transformation. We validate the approach with a simulation and application to a large linked employer-employee database.

Land, labor, indigenous knowledge and institutional resources of producers in the Central Highlands of Ethiopia are investigated. Frequency distribution and comparative statistical analysis of the two regions with respect to these and other parameters suggest that in a situation where all producers are subjected to a common source of risk (e.g. rainfall): i) the institutional resources become less effective, and ii) combination of land, labor, knowledge and other complementary resources form the basis for adjustment mechanisms, sequential or strategic decisions, and that these decisions are directed towards maintaining the nuclear family. On the other hand, when essential resources such as land are government owned and household decisions are shared by the state, local institutions or social networks become an effective means to maintain reproduction of the farm and the producer through providing access to or sharing of resources.

In recent years, an important number of impact studies have attempted to examine the effect of credit on income poverty; however, many of these studies have not paid sufficient attention to the problems of endogeneity and selection bias. The few exceptional cases have employed econometric techniques that work at the village level. The problem is that the concept of village is inappropriate in the urban context where a large percentage of microfinance organisations in the developing world actually operate. This paper presents an econometric approach which controls for endogeneity and self-selection using data from a quasi-experiment designed at the household level, and conducted in three urban settlements in the surroundings of the Metropolitan area of Mexico City. The paper provides an estimation of the impact of credit, employing different equivalence scales in order to measure the sensitivity of the poverty impact to the intra-household distribution of welfare. We find a link between poverty impacts and lending technology. Group-based lending programmes are more effective in reducing the poverty gap but in doing so, they achieve insignificant impacts on the poverty incidence. By contrast, individual lending programmes reported significant and small impacts at the upper limits of deprivation but insignificant impacts on the poverty gap.

C81 - Methodology for Collecting, Estimating, and Organizing Microeconomic Data ; Data Access
Does the labeling of products which have been produced without any child laborers
contribute to increased welfare of children? This paper presents some results of a survey in Nepal conducted to analyze which factors determine the probability of a child to work, and to examine the influence of non governmental organizations (NGOs) which are engaged in social labeling, on the incidence of child labor and child schooling. Data were obtained from interviews with 410 households of Kathmandu Valley in Nepal. The results of the econometric analysis show that the probability of child labor (i) decreases if the carpet industry has implemented a labeling program, (ii) decreases if the adult’s income increases (‘luxury axiom’), (iii) decreases if the head of the household is educated, (iv) increases with the age of the head of the household, and (v) is increased in the presence of more children (aged 5-14) in the household. It can also be shown that labeling NGOs have a significant positive influence on sending the ex-child laborers
to school.

Verification of Citations: Fawlty Towers of Knowledge?
Wright, Malcolm
Armstrong, J. Scott
Y8 - Related Disciplines
C81 - Methodology for Collecting, Estimating, and Organizing Microeconomic Data ; Data Access
B4 - Economic Methodology
The prevalence of faulty citations impedes the growth of scientific knowledge. Faulty citations include omissions of relevant papers, incorrect references, and quotation errors that misreport findings. We discuss key studies in these areas. We then examine citations to Estimating nonresponse bias in mail surveys, one of the most frequently cited papers from the Journal of Marketing Research, as an exploratory study to illustrate these issues. This paper is especially useful in testing for quotation errors because it provides specific operational recommendations on adjusting for nonresponse bias; therefore, it allows us to determine whether the citing papers properly used the findings. By any number of measures, those doing survey research fail to cite this paper and, presumably, make inadequate adjustments for nonresponse bias. Furthermore, even when the paper was cited, 49 of the 50 studies that we examined reported its findings improperly. The inappropriate use of statistical-significance testing led researchers to conclude that nonresponse bias was not present in 76 percent of the studies in our sample. Only one of the studies in the sample made any adjustment for it. Judging from the original paper, we estimate that the study researchers should have predicted nonresponse bias and adjusted for 148 variables. In this case, the faulty citations seem to have arisen either because the authors did not read the original paper or because they did not fully understand its implications. To address the problem of omissions, we recommend that journals include a section on their websites to list all relevant papers that have been overlooked and show how the omitted paper relates to the published paper. In general, authors should routinely verify the accuracy of their sources by reading the cited papers. For substantive findings, they should attempt to contact the authors for confirmation or clarification of the results and methods. This would also provide them with the opportunity to enquire about other relevant references. Journal editors should require that authors sign statements that they have read the cited papers and, when appropriate, have attempted to verify the citations.

De facto anonymised microdata file on income tax statistics 1998

C81 - Methodology for Collecting, Estimating, and Organizing Microeconomic Data ; Data Access
With the data of the de facto anonymised Income Tax Statistics 1998 (FAST 98), the German
official statistics are for the first time publishing microdata from the field of fiscal statistics.
The scientific community can use these data to analyse politically-relevant questions on the
fiscal and transfer system at their own workplace, subject to the premises of article 16 subsection
6 of the Law on Statistics for Federal Purposes, on the basis of "real" assessment data.
Passing on individual data to the scientific community is only possible in a de facto
anonymised form. This form may impair possibilities for scientific analysis possibilities. So
that anonymised data can nevertheless be used by the scientific community, anonymisation
must meet two equal challenges: It must firstly guarantee adequate protection of the
individual items of data, and secondly it must optimally conserve the possibilities for analysis
of the anonymised data. In order to achieve the right balance between these two goals, the
Statistical Offices have involved potential scientific users in the anonymisation work in a
research project.In the article entitled "De facto anonymised microdata file on income tax
statistics 1998", in addition to the anonymisation concept the framework conditions of the
project are explained and the analysis possibilities of income tax statistics demonstrated.

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.

This essential dimensions of microsimulation as an instrument to analyze and forecast
the individual impacts of alternative economic and social policy measures are surveyed
in this study. The basic principles of microsimulation, which is a tool for practical
policy advising as well as for research and teaching, are pointed out and the static and
dynamic (cross-section and life-cycle) approaches are compared to one another. Present
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.

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.

We investigate profit-maximizing versioning plans for an information goods monopolist.
The analysis employs data obtained from a web-based field experiment in which potential
buyers were offered information goods in varied price-quality configurations. Maximum
simulated likelihood (MSL) methods are used to estimate parameters describing the
distribution of utility function parameters across potential buyers of the good. The
resulting estimates are used to examine the impact of versioning on seller profits and
market efficiency.

This paper presents an estimation of the impacts of microcredit on labor and human capital following a quasi-experiment specifically designed to control for endogeneity and selection bias in the context of urban Mexico. We find important indirect trickle-down effects of credit through labor expenditure that benefit poor laborers; however, these effects were only observed when loan-supported enterprising households reached a level of income well above the poverty line. We also find significant, although small impacts of credit on
children´s schooling that could be potentially reinforced by improvements in lending technology, school grants and additional ex-ante preventive and ex-post protective riskcoping products.

The focus of this article is to present the modelling tehcniques used on international practice in the evaluation of right life premiums based. The knowledge and models obtained have a common element of mortality risk indicators but these are varied in different parts of the world. The common elements of these studies and models are generally based on a series of indicators which mainly point out their probability of survival and they are named the mortality indicators. These indicators represent the basis for the calculation of the premiums quotes and for the elaboration by the insurers of premium tables. The benefit for the policyholder is to obtain insurance at a fair and competitive price and for the insurer, to maintain the experience of its portfolio in line with mortality assumptions.

The possibility of taking photographs of the Earth from the sky first, and from space later, has allowed researchers much more than obtaining superb views. Adequately processed and interpreted data obtained from these images through multi-spectral sensors have provided valuable information to diverse branch of the science and public and private institutions. Historically related with the Defense area, information gathered by aerial and spacial photographs have been also well received in the civil sector. The capacity of mounting sensors in satellites to see things invisible for the open human eye brings the possibility to enrich research fields in the same way it improves decision maker due to the higher quality of information. This report has the initial goal of introducing basic topics in the field of remote-sensing, their fundamentals, and the applicability into diverse research fields.

A microeconomic model is developed, which accurately predicts the shape of personal income distribution (PID) in the United States and the evolution of the shape over time. The underlying concept is borrowed from geo-mechanics and thus can be considered as mechanics of income distribution. The model allows the resolution of empirical and definitional problems associated with personal income measurements. It also serves as a firm fundament for definitions of income inequality as secondary derivatives from personal income distribution.
It is found that in relative terms the PID in the US has not been changing since 1947. Effectively, the Gini coefficient has been almost constant during the last 60 years, as reported by the Census Bureau.

A generalized exploratory method for managerial analysis and business communication

Contemporary managerial processes are focused on communication and negotiation, where efficiency acquires an essential importance and its variation related to the managerial programme, with its time or space details, respectively related to the effectiveness of management, statistics, mathematics, etc. All these sciences and their methods meant to identify regularities and to generalize the alternatives, emphasizing their fundamental contribution to the majority of the results of the organizations, regions and national economies. This paper illustrates cybernetic communication’s theories based on information (with special stress being laid on the notions of data, language, message and decoding/encoding), and also underlines the functions and models of communication, the kind of form, and expression relationship human communication intends to achieve, the types of information with relation to communication, knowledge and creation, semantic, statistical and mathematical aspects woven into communication, the levels of theoretical approach of communication (with respect to the accuracy of symbol transmission, the accuracy of signification conveyed through symbols, and the efficacy of its influence on the recipient). The latter analysis (belonging to Warren Weaver) is specifically dwelt on, with special emphasis on the managerial activities. Initially the author proposes six solutions of using some methods of analysis, out of which one is strictly logical, then four distinct methods mainly statistical and mathematical in nature, and, in the end, one that is mainly sociological (the method of the flattened networks of internet type). The methods briefly presented easily characterize the communication, negotiation, and, finally, the decision-making processes, but especially their aggregation in an ample process, the managerial one. The frame method of the four “E” becomes the expression of the statistical way of thinking through effects and efforts of the economic activities, but it does not exclusively belong to them, it initiates a chain of efficaciousness-degree of economy-efficiency-effectiveness type, a chain that allows the interpretation, the placement in hierarchical order and the comparison of the processes and systems, whereas mathematics through the richness of the solutions, from using the probabilities of occurrence of the effects, to the informational energy, complete and generalize the entirety. Thus, there results a new economic paradigm of Homo Effectus, able to substitute the already contested Homo Rationalis.

In the Gangetic flood plain of West Bengal, wetlands are used for multiple purposes, and have significant
role in the livelihoods of the local people. Over the years, these Multiple Use Systems (MUSs) are getting converted to single use systems due to economic and social pressure from dominant stakeholders, which are higher than that in single use systems. Economic and ecological functions of MUS changes over time and space. These dynamic aspects of MUS are often not fully appreciated. Attempts to classify wetlands according to their uses across ecological zones and to do their economic valuation are very limited.
Based on available secondary information, a wetland was selected in Bardhaman district of West Bengal to evaluate the economic benefits from multiple uses namely, wetland cultivation, irrigation, fisheries, jute retting, and
fodder collection. The study shows that the major economic benefits that people living in the surrounding area of
wetland derive are from wetland cultivation; direct irrigation; jute retting; and fisheries. The most important benefit was from fisheries, followed by wetland cultivation and jute retting. The irrigation benefits were found to be low due to larger distance of the land from the wetland, and the easy access to shallow groundwater in the region. However, the many ecological functions of the wetlands are not evaluated in the study.

Introduction. The objects of investigation of this work are micro-level behaviors in stock markets. We aim at better understanding which strategies of market participants drive stock markets. The problem is that micro-level data from real stock markets are largely unobservable. We take an estimation perspective to obtain daily time series of fractions of chartists and fundamentalists among market participants. We estimate the heterogeneous agent-based financial market model introduced by Lux and Marchesi [1] to the S&P 500. This model has more realistic time series properties compared to less complex econometric and other agent-based models. Such kinds of models have a rather complex dependency between micro and macro parameters that have to be mapped to empirical data by the estimation method. This poses heavy computational burdens. Our contribution to this field is a new method for indirectly estimating time-varying micro-parameters of highly complex agent-based models at high frequency.
Related work. Due to the high complexity, few authors have published on this topic to date (e.g., [2], [3], and [4]). Recent approaches in directly estimating agent-based models are restricted to simpler models, make simplifying assumptions on the estimation procedure, estimate only non-time varying parameters, or estimate only low frequency time series.
Approach and computational methods. The indirect estimation method we propose is based on estimating the inverse model of a rich agent-based model that derives realistic macro market behavior from heterogeneous market participants’ behaviors. Applying the inverse model, which maps macro parameters back to micro parameters, to widely available macro-level financial market data, allows for estimating time series of aggregated real world micro-level strategy data at daily frequency. To estimate the inverse model in the first place, a neural network approach is used, as it allows for a large degree of freedom concerning the structure of the mapping to be represented by the neural network. As basis for learning the mapping, micro and macro time series of the market model are generated artificially using a multi-agent simulation based on RePast [5]. After applying several pre-processing and smoothing methods to these time series, a feed-forward multilayer perceptron is trained using a variant of the Levenberg-Marquardt algorithm combined with Bayesian regularization [6]. Finally, the trained network is applied to the S&P 500 to estimate daily time series of fractions of strategies used by market participants.
Results. The main contribution of this work is a model-free indirect estimation approach. It allows estimating micro-parameter time series of the underlying agent-based model of high complexity at high frequency. No simplifying assumptions concerning the model or the estimation process have to be applied. Our results also contribute to the understanding of theoretical models. By investigating fundamental depen¬den¬cies in the Lux and Marchesi model by means of sensitivity analysis of the resulting neural network inverse model, price volatility is found to be a major driver. This provides additional support to findings in [1]. Some face validity for concrete estimation results obtained from the S&P 500 is shown by comparing to results of Boswijk et al. [3]. This is the work which comes closest to our approach, albeit their model is simpler and estimation frequency is yearly. We find support for Boswijk et al.’s key finding of a large fraction of chartists during the end of 1990s price bubble in technology stocks. Eventually, our work contributes to understanding what kind of micro-level behaviors drive stock markets. Analyzing correlations of our estimation results to historic market events, we find the fraction of chartists being large at times of crises, crashes, and bubbles.

Impact of aggregation on measuring FDI spillovers: a Monte Carlo appraisal
Sun, Sizhong
D20 - General
C81 - Methodology for Collecting, Estimating, and Organizing Microeconomic Data ; Data Access
Using a Monte Carlo experiment, this paper explores the impact of data aggregation on measuring the FDI spillovers. We find the aggregation significantly covers up the spillovers, which is further exacerbated by the correlation between the foreign presence and the explanatory variable at the disaggregate level. However, if the FDI at the level of aggregation is proportional to its domestic counterparts, then the aggregation does not affect the measurement of spillovers.

ActiveX is a set of technologies that has the potential to change the way information is accessed and used on the Internet; allows software components to interact with one another in a networked environment, regardless of the language in which the components were created. Powerful abstractions based on OLE have been developed to enable fast, scaleable integration of your objects within the Internet. Microsoft is making a major effort to make the Internet everything it can possibly be. By using ActiveX, developers can make the best use of their system resources while providing instant, dynamic content and functionality in their Internet applications. How information is presented greatly affects how interesting and usable people find it.

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.

improvements and future challenges of time use and time budgets for policy and research with focus
on international and in particular German national developments. It is written in the sequel of the last
German KVI commission report on the improvement of the information infrastructure between
sciences and statistics.
Topics are: recent :international time use institutions, data archives and surveys; German time use data
bases and their access, actual time use research fields and studies; time use and economic and social
policy; new methods in time use survey sampling, future developments and European and
international challenges. The conclusions recommend first of all a new German Time Use Survey
GTUS 2011/12 and urgently calls for its financing and start of organisation. Specific GTUS
improvements, SOEP time use issues, a brand new time use panel and a permanent establishment of
the German research data centres (RDCs) are recommended in addition.

Le Inchieste Congiunturali dell'ISCO: aspetti metodologici; Chapter 1 of: Le inchieste dell'ISCO come strumento di analisi della congiuntura economica
Martelli, Bianca Maria
C81 - Methodology for Collecting, Estimating, and Organizing Microeconomic Data ; Data Access
The Business Tendency Surveys, performed by ISCO (Institute for Short-Term Economic Studies) for Italy, are part of the Joint Harmonised Business and Consumers Survey (BCS) program of the European Commission which cover manufacturing, construction, retail trade, service sectors and consumers. ISAE (formerly ISCO) is one of the three founder Institutes (with IFO in Germany and INSEE in France) of the project.
BCS started to be conducted in manufacturing sector since early 60 th’s , progressively enlarging over the years the field of investigation to construction, consumers, investments, retail trade and services.
Business Tendency Surveys aim to investigate the “confidence” of the economic operators by asking entrepreneurs and managers opinions on current trends and expectations for the near future, regarding both their own business and the general situation of the economy. Information collected is of a qualitative type, mainly with a three option ordinal scale. Only in some restricted cases, for variables that are not reported in conventional statistics, information collected is quantitative: percentages of capacity utilization or the number of months of production assured.
Answers obtained from the survey are aggregated in the form of “balances” (differences between positive and negative answers). Balances are then used to build the confidence indicator as arithmetic mean of selected series, namely for manufacturing: order level, production expectation and stocks (with inverted sign). The time series of the manufacturing confidence indicator often represent a leading indicator of the industrial production and of the GDP.
In this chapter, which is part of a more general (and unfortunately out of print) ISCO publication, the first synthetic but precise and organic discussion of all the surveys is presented. The history of the ISCO surveys is presented and all the aspects of carrying out a survey are described starting from universe to the frame list, the sampling design, the lay out of the questionnaire, the data collection technique, the data processing and weighting and the confidence indicators calculation.

Happiness research is on the rise, but is confounded by competing definitions of subjective well-being based on co-existing concepts, resulting in differing measures and giving rise to different potential policy applications.
This paper motivates the societal necessity for using well-being indicators and gives a short overview of the relation between the concepts ‘subjective well-being’, ‘affect’, ‘life satisfaction’, and ‘happiness’. It describes their measurements and operationalizations in surveys, illustrates their philosophical roots, discusses their validity and reliability, and attempts to shed light on the scope of their policy applicability. Focus of this paper is on practical issues when applying measures of subjective well-being for policy evaluations. Target audiences of this paper are the interested public and laypersons, non-expert economists, and statisticians.

Through an implementation of the 2-level-approach due to Vesanto & Alhoniemi (2000), this paper addresses a number of problems typically seen when visualized interpretation of Self Organizing Maps (SOM) are applied to derive a systematic classification system in the hedge fund literature. Normally, a trained SOM does not result in an exact depiction of the detected structures of the input data, and is therefore challenging for visual interpretations. The 2-level-approach overcomes this problem and assures a consistent clustering of neighboring output units, and therefore an objective classification scheme. Through an empirical application, such an objective classification is derived. Building on this, further analyses concerning the misclassification and style creep problems are conducted. Within the ten-year sample period (31.01.1999 to 31.12.2008), which comprises 2789 hedge funds, organized in eleven strategies, six classes can be identified. This six-class taxonomy is fairly robust to different sub-sample periods, topologies and data-samples. According to the classification system applied here, it is shown that most of the analyzed hedge funds are inconsistent in their self-declared strategies. Furthermore, evidence of undisclosed trading style changes over time is identified – specifically, it is shown that misclassified hedge funds are more likely to change their trading style.

The paper provides an alternative explanation for the “resource curse” based on the income effect resulting from high government current spending in resource rich economies. Using a simple life cycle framework, we show that private investment in the non-resource sector is adversely affected if private agents expect extra government current spending financed through resource sector revenues in the future. This income channel of the resource curse is stronger for countries with lower degrees of openness and forward altruism. We empirically validate these findings by estimating non-hydrocarbon sector growth regressions using a panel of 25 oil-exporting countries over 1992–2005.

Calibración de modelos de equilibrio general computado: Métodos y práctica usual

C68 - Computable General Equilibrium Models
C81 - Methodology for Collecting, Estimating, and Organizing Microeconomic Data ; Data Access
The present article presents a discussion of the methods generally adopted to build the database and to estimate the parameters that requires the implementation of computable general equilibrium models. Basically, this paper deals with “calibration” procedures for CGE models, which are utilized to infer economic data parameters values of a specific period, and that once specified those values in a model applied, reproduce endogenously the data of the period base as a solution. These procedures are the construction of the social accounting matrix, and the utilization of the cross entropy method to assure the consistency; the final calibration of the behavioral parameters and the validation of the model. The main objective is to present the methods, for which some examples were developed, and the related literature that is essential for their implementation.

Redistributing incomes has always been one of the main goals of Iranian policy makers, although political regimes have changed frequently between 1991 and 2004. We have applied a microsimulation using the Oaxaca-Blinder decomposition and a Heckman correction for sample selection bias to compare simulation results for a hypothetical unchanged situation with the actual policy shift observed. While we are able to identify the years in which policy shifts occurred, our results suggest that the intended redistribution goals were at most partially achieved, affecting only some occupations and being offset by changes to the level of family incomes.

This paper attempts to find the optimal formation of three midfielders and three forward football players on ground, using the classic Quadratic Assignment Problem or Facility Layout problem. Players are treated as “machines”, their positions as locations, and the flow of materials between machines as “flow of passes” and “flow of markings”. Based on detailed statistics from four matches of AC Milan, and formulated the problem as minimum (quick strategy), maximum (slow strategy), and mixed or balanced strategies, a number of various layouts emerged. Compared to the initial formation of players, the efficiency time gains in the unconditioned layouts are between 3 and 6.8%. Also, when the manager claims that his three forwards shouldn’t shift positions with the midfielders, the efficiency gains in these restricted layouts is about 14´´ to 74´´, which is about 1 to 3% of the approximately 40´ effective time spent into passes and markings from both teams.

Questo paper presenta un questionario e una guida pratica per la misurazione del capitale sociale. Il lavoro vuole costituire un vero e proprio manuale rivolto a ricercatori, studenti e docenti, consulenti di impresa e operatori del terzo settore che per qualsiasi ragione, dalla redazione della tesi di laurea alla valutazione dell’assetto organizzativo di un’azienda, siano alle prese con la misurazione del capitale sociale e di altri fenomeni poco tangibili ma economicamente rilevanti. In questo contesto, il capitale sociale è trattato nelle sue molteplici sfaccettature. Ciascuna dimensione è fotografata da un gruppo di domande, elaborate a partire dalle considerazioni fornite dalla letteratura teorica oppure dagli spunti provenienti dalla ricerca empirica.
This paper presents a guidebook and a questionnaire for the measurement of social capital. Our aim is to provide researchers, teachers, students, and practictioners with a set of practical instructions and tools to carry out empirical research on social capital and other related intangible assets.

Voting features based classifiers, shortly VFC, have been shown to perform well on most real-world data sets. They are robust to irrelevant features and missing feature values. In this paper, we introduce an extension to VFC, called voting features based classifier with feature construction, VFCC for short, and show its application to the problem of predicting if a bank will encounter financial distress, by analyzing current financial statements. The previously developed VFC learn a set of rules that contain a single condition based on a single feature in their antecedent. The VFCC algorithm proposed in this work, on the other hand, constructs rules whose antecedents may contain conjuncts based on several features. Experimental results on recent financial ratios of banks in Turkey show that the VFCC algorithm achieves better accuracy than other well-known rule learning classification algorithms.

This paper deals with estimating data from experiments determining lottery certainty equivalents. The paper presents the parametric and nonparametric results of the least squares (mean), quantile (including median) and mode estimations. The examined data are found to be positively skewed for low probabilities and negatively skewed for high probabilities. This observation leads to the striking conclusion that lottery valuations are only nonlinearly related to probability when means are considered. Such nonlinearity is not confirmed by the mode estimator in which case the most likely lottery valuations are close to their expected values. This means that the most likely behavior of a group is fully rational. This conclusion is a significant departure from one of the fundamental results concerning lottery experiments presented so far.

Disaster risk is a major concern in a developing country like India as people living in disaster prone regions of the country are subject to variety of risks concerning their livelihoods. Preliminary assessments reveal that the severity and intensity of floods in various parts of India might increase due to climate change. This paper attempts to understand the various risks faced by households living in disaster prone regions of rural India and specifically examine the effectiveness of coping mechanisms adopted by households living in these areas to hedge against the risks. The study area (districts of eastern Uttar Pradesh, India) is highly susceptible to floods with a major flood occurring every ten years and smaller ones happening every one-two years. The data is drawn from primary household surveys undertaken in the study area for flood affected households. The analysis is carried out using a risk sharing and self insurance framework and econometric modeling is carried out using binary outcomes and multivariate probit estimation through GHK (Geweke- Hajivassiliou- Keane) estimator. Based on the empirical analysis, and subject to the assumptions and the usual limitations of data used, the findings of the study suggest that: (i) overall the impacts of disasters on the consumption level of the household exhibit an inverse relationship, (ii) consumption smoothening behaviour is not exhibited by the households and (iii) household specific characteristics along with the geographical location of the households have no significant role to play with respect to the changes in consumption in the flood prone districts of eastern Uttar Pradesh.

This paper presents a regression procedure for inhomogeneous data characterized by varying variance, skewness and kurtosis or by an unequal amount of data over the estimation domain. The concept is based first on the estimation of the densities of an observed variable for given values of explanatory variable(s). These density functions are then used to estimate the relation between all the variables. The mean, quantile (including median) and mode re-gression estimators are proposed, with the last one appearing to be the maximum likelihood estimator in the density based approach. The paper demonstrates the advantages of the pro-posed methodology, which eliminates most of the estimation problems arising from data inhomogeneity. These include the computational inconveniences of the standard quantile and mode regression techniques. The proposed methodology, when applied to lottery experiments, makes it possible to confirm and to extend the previously presented conclusion (Kontek, 2010) that lottery valuations are only nonlinear with respect to probability when medians and means are considered. Such nonlinearity disappears once modes are considered. This means that the most likely behavior of a group is fully rational. The regression procedure presented in this paper is, however, very general and may be applied in many other cases of data inhomogeneity and not just lottery experiments.

This paper studies performance of synthetic ratio estimator and composite estimator, which is a weighted sum of direct and synthetic ratio estimators, under Lahiri – Midzuno (L-M) sampling scheme. The synthetic estimator under L-M
scheme is unbiased and consistent if the assumption of synthetic estimator is satisfied. Further, this paper compares performance of the synthetic and
composite estimators empirically under L-M and SRSWOR schemes for estimating crop acreage for small domains. The study shows that both the estimators perform better under L-M scheme as having comparatively smaller
absolute relative biases and relative standard errors.

The social capital has strengthened the solidarity funds when the legal mechanisms and institutions for monitoring and assistance would not have been present. The aim of this paper is to analyze the effect of social capital on productivity and performance of the Mexican solidarity funds. For this it is obtained an estimator indirectly associated with inequality, through which it follows that if the social capital rises 1% the loans number increases by 0.2877% and the savings number increases by 0.4598%, and for each additional producer that activate his social capital with his partners they will be generated increases in loans recoveries amounting to 597.41 pesos. In this sense, a greater investment in social capital will recover a larger amount of borrowed funds and will increase savings and loans to poor producers

Social capital has strengthened the solidarity funds when the legal mechanisms and institutions for monitoring and assistance are not present. The aim of this paper is to analyze the effect of social capital on productivity and performance of microfinance’s cooperatives using the Mexican solidarity funds. For this, an estimator indirectly associated with inequality was obtained and extrapolation method was used. The results show that if the social capital rises 1%, the number of loans and the savings amount increases in percentage terms; for each additional producer that activates its social capital with its partners there will be a general increase in loans recoveries. In this sense, a greater investment in social capital will recover a larger amount of borrowed funds and will increase savings and loans to poor producers.

Intrahousehold Analysis Using Household Consumption Data: Would the Potential Benefit of Collecting Individual-Level Consumption Data Justify Its Cost?
Fuwa, Nobuhiko
D13 - Household Production and Intrahousehold Allocation
C81 - Methodology for Collecting, Estimating, and Organizing Microeconomic Data ; Data Access
O12 - Microeconomic Analyses of Economic Development
This paper examines the usefulness and limits of household consumption expenditure data for understanding intrahousehold resource allocation issues. It also examines alternative data collection methods for obtaining household consumption information to be used for addressing such issues.
While the high cost involved in the collection of fully individual-level data collection, particularly of food intake data, is generally likely to exceed potential benefit in the context of large-scale and nationally representative household surveys, partially individualized consumption data collection (e. g., education and health), is highly desirable and relatively inexpensive. Furthermore, we explore possible conditions under which collecting individual-level food intake data could be worthwhile. Such conditions are mainly determined in terms of both research foci/policy priorities at hand, and the characteristics of the study areas.

Using very basic mathematical tools the paper endeavors to answer the questions: How to determine the “average” subject in a group? How to find a subject presenting the most similar behavior to a given one? How to detect outlier subject(s)? How to classify behaviors by their dissimilarity from the perfectly rational decision maker? How to rank subjects by risk attitudes? How to cluster subjects? This paper demonstrates that the answer to all of these questions may be found non-parametrically, without the use of any specific model.

Knowledge clusters are central places within an epistemic landscape, i.e. in a wider structure of knowledge production and dissemination. They have the organisational capability to drive innovations and create new industries. Examples of such organisations in knowledge clusters are universities and colleges, research institutions, think tanks, government research agencies and knowledge-intensive firms with their respective knowledge workers.
The following paper will look at Malaysia and its path towards a Knowledge-based economy. We first describe the development strategy of the Malaysian government which has emphasized cluster formation as one of its prime targets. We then provide evidence of the current state of knowledge cluster formation in Peninsular Malaysia and try to answer the following questions. If the formation of a knowledge cluster (especially in the ICT and multimedia industry) has been the government policy, what has been the result? Has Malaysia developed an epistemic landscape of knowledge clusters? Has the main knowledge cluster really materialised in and around Cyberjaya in the MSC Malaysia?
Data collected from websites, directories, government publications and expert interviews have enabled us to construct the epistemic landscape of Peninsular Malaysia. Several knowledge clusters of a high density of knowledge producing institutions and their knowledge workers have been identified and described. The analysis of the knowledge output, measured in terms of scientific publications, patents and trademarks show that existing knowledge clusters have, indeed, been productive as predicted by cluster theory. On the other hand government designed development corridors do not always coincide with the distribution of knowledge assets. The analysis of our data pertaining to Cyberjaya, the MSC Malaysia and the “corridors” needs to be developed further to produce more robust results.

C81 - Methodology for Collecting, Estimating, and Organizing Microeconomic Data ; Data Access
Applied econometricians tend to show a long neglect for the proper frequency to be considered while sampling the time series data. The present study shows how spectral analysis can be usefully employed to fix this problem. The case is illustrated with ultra-high-frequency data and daily prices of four selected stocks listed on the Sao Paulo stock exchange.

In this paper we apply the Complete Analysis of Differentiable Games (introduced by D. Carfì in [3], [6], [8] and [9]) and al-ready employed by himself and others in [4], [5], [7]) to the classic Bertrand Duopoly (1883), classic oligopolistic market in which there are two enterprises producing the same commodity and selling it in the same market. In this classic model, in a competitive background, the two enterprises employ as possible strategies the unit prices of their product, contrary to the Cournot duopoly, in which the enterprises decide to use the quantities of the commodity produced as strategies. The main solutions proposed in literature for this kind of duopoly (as in the case of Cournot duopoly) are the Nash equilibrium and the Collusive Optimum, without any subsequent critical exam about these two kinds of solutions. The absence of any critical quantitative analysis is due to the relevant lack of knowledge regarding the set of all possible outcomes of this strategic interaction. On the contrary, by considering the Bertrand Duopoly as a differentiable game (games with differentiable payoff functions) and studying it by the new topological methodologies introduced by D. Carfì, we obtain an exhaustive and complete vision of the entire payoff space of the Bertrand game (this also in asymmetric cases with the help of computers) and this total view allows us to analyze critically the classic solutions and to find other ways of action to select Pareto strategies. In order to illustrate the application of this topological methodology to the considered infinite game, several compromise pricing-decisions are considered, and we show how the complete study gives a real extremely extended comprehension of the classic model.

This paper combines unique survey and experimental data to examine the determinants of self-selection into a vocational training program. Women residing in selected disadvantaged areas in New Delhi, India were invited to apply for a 6-month long free training program in stitching and tailoring. A random subset of applicants and non-applicants were invited to participate in a set of behavioral experiments and in a detailed socio-economic survey. We find that applicants and non-applicants differ both in terms of observables (captured using survey data) and also in terms of a number of intrinsic traits (captured via the behavioral experiments). Overall our results suggest that there is valuable information to be gained by dissecting the black box of unobservables using behavioral experiments.

The general aim of this article is to present genetic algorithms as a tool, that can be used in de-mand forecasting in internet shops. First part of article identities factors, which have to be taken into consideration during analysing demand in internet shops, e.g. dispersion of demand, delivery time in-fluence and different e-marketing factors. Specific form of used demand function is shown in the next section of the article. Then genetic algorithm is defined by its genetic operators acting on bit strings (examples of the operators are: crossover, inversion, and mutation) and its method of credit allocation (fitness evaluation and selection). Next the method of identification of the function parameters using genetic algorithms is shown. The next part of article shows appliance of presented genetic algorithm. The advantages and disadvantages of proposed method are shortly discussed in summary.

The Banks&Businesses Regional Observatory on Economy and Finance (OBI)
and the University of Tirana carried on the first qualitative survey on Albanian
enterprises between July and September 2008. The main advantages of
qualitative surveys are that they are able to catch the “business climate”; are
very timely and quite inexpensive; are more robust against misreporting than
traditional surveys. A number of statistical techniques allow converting the
results of qualitative surveys in quantitative indicators. In general, the survey
was a successful experiment that shed some light on the structure and
dynamics of the Albanian economy. In particular, the survey confirmed that
Italy and Apulia are among the most interesting markets for the Albanian
firms, and vice versa, also thanks to subcontracting agreements. Also, many
Albanian firms declared to compete with Italian firms on the same markets.
The majority of respondents seem to have balanced and “modern”
relationships with the bank system, even though the local small Albanian
banks seem to be unable to follow the fast evolution of the most dynamic
firms. This fact suggests the need for restructuring the Albanian credit sector.
The survey confirmed that Albanian economy is fast growing, and that
entrepreneurs are more optimistic about the future, compared to their
European counterparts, at least just before the worsening of the ongoing world
financial crisis. In any case, a number of firms complained for some credit
restriction. Finally, the network of interviewers and respondents established
during the survey can be exploited in the next years to gather timely
information on the evolution of the Albanian economy during 2008 summer.

This study sheds new light on the question of whether or not sentiment surveys, and the expectations derived from them, are relevant to forecasting economic growth and stock returns, and whether they contain information that is orthogonal to macroeconomic and financial data. I examine 16 sentiment surveys of distinct respondent universes and employ the technique of principal components analysis to extract the common signals from the surveys. I show that the ability of different population groups to anticipate correctly economic growth and excess stock returns is not identical, implying that not all sentiment is the same, although there exist some common components. I demonstrate that sentiment surveys have significant predictive power for both GDP growth and excess stock returns, and that the results are robust to the inclusion of information pertaining to the macroeconomic environment and momentum. Furthermore, the findings reject the conventional wisdom that the effect of sentiment is apparent exclusively in small-capitalization stocks.

For decades, the academic literature has focused on three survey measures of expected inflation: the Livingston Survey, the Survey of Professional Forecasters, and the Michigan Survey. While these measures have been useful in developing models of forecasting inflation, the data are low frequency measures which appear anachronistic in the modern era of high frequency and real-time data. I present a collection of 37 different measures of inflation expectations, including many previously unexploited monthly and real-time measures of inflation expectations. These higher frequency measures tend to outperform the standard three low frequency survey measures in tests of accuracy, predictive power, and rationality, indicating that there are benefits to using higher frequency measures of inflation expectations. Out of sample forecasts confirm the findings.

Essential Data, Budget Sets and Rationalization
Forges, Françoise
Iehlé, Vincent
D11 - Consumer Economics: Theory
C81 - Methodology for Collecting, Estimating, and Organizing Microeconomic Data ; Data Access
According to a minimalist version of Afriat’s theorem, a consumer behaves as a utility maximizer if and only if a feasibility matrix associated with his choices is cyclically consistent. An ”essential experiment” consists of observed consumption bundles (x1,xn) and a feasibility matrix α. Starting with a standard experiment, in which the economist has specific budget sets in mind, we show that the necessary and sufficient condition for the existence of a utility function rationalizing the experiment, namely, the cyclical consistency of the associated feasibility matrix, is equivalent to the existence, for any budget sets compatible with the deduced essential experiment, of a utility function rationalizing them (and typically depending on them). In other words, the conclusion of the standard rationalizability test, in which the economist takes budget sets for granted, does not depend on the full specification of the underlying budget sets but only on the essential data that these budget sets generate. Starting with an essential experiment (x1,...,xn;α), we show that the cyclical consistency of α, together with a further consistency condition involving both (x1,...,xn) and α, guarantees that the essential experiment is rationalizable almost robustly, in the sense that there exists a single utility function which rationalizes at once almost all budget sets which are compatible with (x1,...,xn;α). The conditions are also trivially necessary.

This study sheds new light on the question of whether or not sentiment surveys, and the expectations derived from them, are relevant to forecasting economic growth and stock returns, and whether they contain information that is orthogonal to macroeconomic and financial data. I examine 16 sentiment surveys of distinct respondent universes and employ the technique of principal components analysis to extract the common signals from the surveys. I show that the ability of different population groups to anticipate correctly economic growth and excess stock returns is not identical, implying that not all sentiment is the same, although there exist some common components. I demonstrate that sentiment surveys have significant predictive power for both GDP growth and excess stock returns, and that the results are robust to the inclusion of information pertaining to the macroeconomic environment and momentum. Furthermore, the findings reject the conventional wisdom that the effect of sentiment is apparent exclusively in small-capitalization stocks.

I present evidence that higher frequency measures of inflation expectations outperform lower frequency measures of inflation expectations in tests of accuracy, predictive power, and rationality. For decades, the academic literature has focused on three survey measures of expected inflation: the Livingston Survey, the Survey of Professional Forecasters, and the Michigan Surveys of Consumers. While these measures have been useful in developing models of forecasting inflation, the data are low frequency measures that are anachronistic in the modern era of high frequency and real-time data. I present a collection of 37 different measures of inflation expectations, including many previously unexploited monthly and real-time measures of inflation expectations. These higher frequency measures tend to outperform the standard three low frequency survey measures in tests of accuracy, predictive power, and rationality, indicating that there are benefits to using higher frequency measures of inflation expectations. Out of sample forecasts confirm the findings.

Microdata imputations and macrodata implications: evidence from the Ifo Business Survey
Seiler, Christian
Heumann, Christian
C81 - Methodology for Collecting, Estimating, and Organizing Microeconomic Data ; Data Access
C83 - Survey Methods ; Sampling Methods
A widespread method for now- and forecasting economic macro level parameters such as GDP growth rates are survey-based indicators which contain early information in contrast to official data. But surveys are commonly affected by nonresponding units which can produce biases if these missing values can not be regarded as missing at random. As many papers examined the effect of nonresponse in individual or household surveys, only less is known in the case of business surveys. So, literature leaves a gap on this issue. For this reason, we analyse and impute the missing observations in the Ifo Business Survey, a large business survey in Germany. The most prominent result of this survey is the Ifo Business Climate Index, a leading indicator for the German business cycle. To reflect the underlying latent data generating process, we compare different imputation approaches for longitudinal data. After this, the microdata are aggregated and the results are compared with the original indicators to evaluate their implications on the macro level. Finally, we show that the bias is minimal and ignorable.

Technical and Allocative efficiency are relative concepts, first it is used conventionally, to know if a producer obtain the maximum level of production, according to the amount of inputs used in the process. The second looks for to know if the producer uses the optimal amounts of inputs in the production process, according to the prices of these production factors. This study use microeconomic data on coffee producers of the Caldas, Quindío and Risaralda to determinate the levels of technical and allocative efficiency using “Data Envelopment Analysis – DEA”. Technical efficiency for small producers it is 3.76%, for middle producer it is 51.71% and big producers it is 60.15%, for the all coffee sector the technical efficiency it is 42.38%. Whereas for the allocative efficiency, the results are 36.13%, 42.98%, 18.86% and 36.50%, respectively. This results show that the coffee Colombian sector it is inefficient technical and allocatively. This means that the big producers uses the correct amount of inputs for maximize the coffee production but they do not produce following the schedule of minimum cost. On the other hand, small and middle producers and for all coffee sector they do not use efficiently the inputs, they do not maximize your coffee production and they do not produce following the minimum cost schedule, this because they are technical and allocatively inefficient.

A cereal in full expansion, maize is currently eaten by two out of every three Cameroonians. The NCRE (National Cereals Research and Extension) project introduced and distributed new improved varieties to increase maize output.
The objective of this research is to study determinants guiding the adoption of new varieties of maize following the example of “Cameroon Maize Series (CMS)” 8704. In relation thereto, a Probit model adapted to membership of a smallholders’ cooperative was used. The study was conducted on 100 farms in Cameroon’s Centre Region. The results show that the zone, the level of education, belonging to a smallholders’ cooperative and market orientation positively affect the probability of adopting improved maize varieties.
The age, area, gender and risk seem to have no effect on the adoption of such varieties.

Covariances and relationships between price indices: Notes on a theorem of Ladislaus von Bortkiewicz on linear index functions

The note examines a generalization of a theorem of Bortkiewicz which relates the difference between a Paasche and a Laspeyres price index to a covariance between price and quantity relatives. The generalized theorem is used to demonstrate a number of interesting special applications. It turns out that some known relationships between two index functions can be expressed more elegantly. In other cases where not much is known yet about how the two functions are related to one another, we could establish an interesting equation on the basis of this theorem. This demonstrates the remarkable flexibility and usefulness of the generalized Bortkiewicz - theorem.

C81 - Methodology for Collecting, Estimating, and Organizing Microeconomic Data ; Data Access
I10 - General
The introduction of the National Rural Health Mission has increased the demand for micro-level data on population and health for use in monitoring, planning and programme implementation. This calls for the introduction of a Health Management Information System (HMIS). The launching of a national portal-based HMIS by Government of India in 2008 was a bold and innovative step. However, there are several challenges that must be overcome to develop HMIS as an effective tool for planning and monitoring. In particular, without training and motivating grass-root functionaries to report HMIS data in an accurate, timely manner and monitor its quality, HMIS data cannot be used for health sector planning. The study analyzed HMIS portal data in details in order to evaluate the quality of HMIS in Uttarakhand, a high focus state with a poor HMIS. It also documents challenges to improve HMIS based on a field survey at selected health facilities in the state.

This study sheds new light on the question of whether or not sentiment surveys, and the expectations derived from them, are relevant to forecasting economic growth and stock returns, and whether they contain information that is orthogonal to macroeconomic and financial data. I examine 16 sentiment surveys of distinct respondent universes and employ the technique of principal components analysis to extract the common signals from the surveys. I show that the ability of different population groups to anticipate correctly economic growth and excess stock returns is not identical, implying that not all sentiment is the same, although there exist some common components. I demonstrate that sentiment surveys have significant predictive power for both GDP growth and excess stock returns, and that the results are robust to the inclusion of information pertaining to the macroeconomic environment and momentum. Furthermore, the findings reject the conventional wisdom that the effect of sentiment is apparent exclusively in small-capitalization stocks.

There has been so much debate on the increasing use of formal methods in Economics. Although there are some studies tackling these issues, those use either a little amount of papers, a small amount of scholars or a short period of time. We try to overcome these challenges constructing a database characterizing the main socio-demographic and academic output of a survey of 438 scholars divided into three groups: Economics Nobel Prize winners; scholars awarded with at least one of six worldwide prestigious economics recognitions; and academic faculty randomly selected from the top twenty economics departments. We give statistical evidence on the increasing trend of number of equations and econometric outputs per article, showing that for each of these variables there have been four structural breaks and three of them have been increasing ones. Therefore, we provide concrete measures of mathematization in Economics. Furthermore, we found that the use and training in mathematics has a positive correlation with the probability of winning a Nobel Prize in certain cases. It also appears that being an empirical researcher as measured by the average number of econometrics outputs has a negative correlation with someone's academic career success.

The term “macroprudential” is usually used in different ways. Sometimes it refers to macroprudential analysis, others to macro-prudential oversight and it also speaks of macroprudential regulation. In this paper, taking into account these concepts, an analysis of what is meant by macroprudential authority, how should it be implemented and should have powers to ensure the stability of the entire financial system is going to be done.
Referring to the local economy, the Charter Reform of the Central Bank of Argentina has entered into force. In regard to financial regulation, within the reform, and unlike it was in force since 1992, it aims to not only to monitor, but to implement regulations on the local financial system to avoid the frequent abuses by various entities .
To perform the analysis of the implementation of a macroprudential authority in Argentina, it is going to be considered the evolution of a particular sector of the real economy, namely tourism. Finally, a measure of this economic sector, that should to detect potential problems in the financial system, is proposed.

This article proposes a general empirical method for the estimation of marginal cost of individual firms. The new method employs the smooth coefficient model, which has a number of appealing features when applied to cost functions. The empirical analysis uses data from a unique sample from which we observe marginal cost. We compare the estimates from the proposed method with the true values of marginal cost, and the estimates of marginal cost that we obtain through conventional parametric methods. We show that the proposed method produces estimated values of marginal cost that very closely approximate the true values of marginal cost. In contrast, the results from conventional parametric methods are significantly biased and provide invalid inference.

The main objective of this study is to estimate the price cap through which the parking service fares should be regulated in Bogota, by means of the theoretical guidelines of the transportation economic theory and under the price fixation criterion. The results of this analysis are evinced based on primary information (surveys), non linear (Box-Cox) total production cost, and mathematics optimization (comparative statics). It is concluded that current price per minute is overestimated.

Present article introduces composite indicator for regional innovative systems of the countries with developing and transitional economy. Using the factor analysis technique it exposes four principal unobservable factors, which reflect basic aspects of regional innovative systems. Those factors are used as sub indicators to elaborate composite indicator of the regional innovative systems. This composite indicator may be used for measurement of the regions innovative lavel. Proposed composite indicator can be easily adapted for other countries with developing and transitional economy (e.g. for the post USSR space). By way of illustration here are provided calculations of sub indicators and the composite indicator for Georgian regions (GRIS-2010).

C81 - Methodology for Collecting, Estimating, and Organizing Microeconomic Data ; Data Access
ECAICI indicator introduced in the present article enables to analyze innovative capacities dynamics of the ECA region (by The World Bank classification) countries in 1996-2010. Thorough research reveals four leading unobservable factors, affecting innovative processes in ECA region. These factors may be referred as Knowledge creation, Economy sophistication, Knowlege Absorption-Diffusion, Human Capital Production. We show that there is a close link between ECAICI indicator and other well-known innovation indicators and show also that there is a close link between ECAICI indicator and GDP per capita. Indicator ECAICI may be applied as an instrument for innovative capacities assessment and analysis. Presented brief analysis of current innovative capacities of Georgia, carried out by means of this indicator serves as illustration of the fact. ECAICI indicator may prove to be useful and interesting also for other post-USSR countries.

Nowadays, when companies are dealing with severe global competition, they are making serious investments in Customer Relationship Management (CRM) strategies. One of the cornerstones in CRM is customer churn prediction, the practice of determining a mathematical relation between customer characteristics and the likelihood to end the business contract with the company. This paper focuses on how to better support marketing decision makers in identifying risky customers in telecom industry by using Predictive Models.
Based on historical data regarding the customer base for a telecom company, we proposed a Predictive Model using Logistic Regression technique and evaluate its efficiency as compared to the random selection. In the future, we will focus on extending our study by integrating more business considerations and mining models in order to adjust the churn models or redesign marketing activities for the telecom industry.

Understanding household savings in China: the role of the housing market and borrowing constraints

This paper examines the role of rising housing prices and borrowing constraints as determinants of China's high household saving rate, especially among young households. Using a life-cycle model of saving behavior in the presence of borrowing constraints, we show that the relationship between housing prices and saving exists only under certain conditions and for certain groups of households. Specifically, when the return on financial instruments is low (which is the case in China), the saving rate of young households may increase with housing prices. This relationship, moreover, is non-linear and depends on the level of wealth. Employing an empirical strategy motivated by the theoretical model, we analyze a dataset of over six thousand Chinese urban households spanning the years 1995, 2002 and 2007. We find evidence that higher housing prices do in fact increase the saving rates of young households. We also find evidence for the predicted non-linearity.

The Caldwellian Methodological Pluralism: Wishful Thoughts and Personal Tendencies

Economists failed badly both to predict and solve the Great Global Recession of 2008-2010 for two interconnected reasons. The first is that economics has moved too far away from its social foundations. The second reason is that the positivist economic methodology that economics follows has produced both benefits and costs, perhaps even costs than benefits, one may argue. This paper looks at the available evidence (not exhaustively) to argue for a Caldwellian methodological pluralism. It illustrates the advantages of such a methodological approach as well as the disadvantages of its alternatives, especially monolithic positivism.

This paper develops a methodology to identify systemically important financial institutions building on that developed by the BCBS (2011) and used by the Financial Stability Board in its yearly G-SIFIs identification. This methodology is based on publicly available data, providing fully transparent results with a G-SIFIs list that helps to bridge the gap between market knowledge and supervisory decisions. Moreover the results encompass a complete ranking of the banks considered, according to their systemic importance scores. The methodology has then been applied to EU and Eurozone samples of banks to obtain their systemic importance ranking and SIFIs lists. A statistical
analysis and some geographical and historical evidence provide further insight into the notion of systemic importance, its policy implications and the future applications of this methodology.

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 paper describes a methodology for the construction of a novel patent dataset for computing consolidated patent portfolios across patent offices. In particular, relying on
two previous contributions – the EPIP database for EPO/PCT patents and the IIP patent database for JPO patent documents – we discuss how to integrate the applicant names of these two databases with the mean of priority information from PATSTAT. This methodology yields significant improvements in the harmonization of applicants name for European firms in IIP patent database and Japanese firms in EPIP database. The paper concludes with a first look to the differences in patenting strategy by European and Japanese firms.

C81 - Methodology for Collecting, Estimating, and Organizing Microeconomic Data ; Data Access
This paper presents a brief analysis of the current innovative capabilities of Georgia based on the Europe-Central Asia Innovative Capability Indicator (ECAICI). This composite indicator is constructed using factor analysis tools. Research reveals that innovative processes in the Europe-Central Asia (ECA) region (by the World Bank classification) are mainly affected by four unobservable factors: knowledge creation, economic sophistication, knowlege absorption-diffusion, and human capital production. We show that the ECAICI is closely related to other well-known innovation indicators and to GDP per capita. The ECAICI was used to analyze the innovative capability dynamics during 1996–2010. This study serves as an illustration for the use of the ECAICI as an instrument for innovative capability assessment and analysis in Georgia and other post-USSR countries

European Union (EU) experience reveal that the composite indicators are probably the most useful instruments for
measuring the innovative capacities at the regional (sub-national) level. However, some gap exists in the current literature with respect to the elaboration of composite indicators for regional innovation systems (RISs) of developing countries. This article introduces the composite indicators GRIS and GCLS for measuring the regional innovative capacities (for GNUTS1 and GNUTS2 territorial classification levels, respectively). Georgia is a useful case-subject because its smallscale developing economy presents special challenges for elaborating the composite indicators for RISs. This article also includes a brief analysis using these composite indicators and indicates the significant heterogeneity among the innovative capacities of the Georgian regions.

Data Fusion Between Bank of Italy-SHIW and ISTAT-HBS

D31 - Personal Income, Wealth, and Their Distributions
The aim of this work is to match household consumption information from Indagine sui Consumi delle Famiglie (Household Budget Survey, HBS) by the Italian National Statistical Institute (ISTAT) with Indagine sui Bilanci delle Famiglie Italiane (Survey of Households’ Income and Wealth, SHIW) by the Bank of Italy. In particular, we combine information from the Historical Database (integrated with information from the original cross sectional files) of SHIW 2010 with the wave 2010 of HBS.
The work offers a review of the main matching methodologies, coupled with a discussion of the underlying hypotheses (such as the CIA) which, in our case, are less demanding to assume given the presence of aggregate consumption as common variable between the two surveys. Moreover, some tests measuring the validity of the matching procedure are presented in order to check the preservation of joint distributions. The resulting sample provides an integrated synthetic dataset which allows to jointly analyze income, wealth and consumption distributions with a high degree of detail for both incomes/assets and consumption expenditure items. This source is expected to allow better multidimensional-distributional analyses on consumption income and wealth and to provide a basis for an integrated microsimulation analysis of direct, indirect and wealth tax reforms which, so far, has not been feasible taking available sample surveys separately.

How To Win Acceptance Of The Inequality Process As Economics?
Angle, John

C81 - Methodology for Collecting, Estimating, and Organizing Microeconomic Data ; Data Access
D31 - Personal Income, Wealth, and Their Distributions
The Inequality Process (IP) is a particle system model similar to that of the Kinetic Theory of Gases. The IP is a parsimonious model of competition among people for wealth. The IP explains a wide scope of stable patterns in the distribution of personal income and wealth. Econophysicists have adopted the IP as part of their field, but the IP has been ignored or rejected by economists even though economists claim expertise on the distribution of personal income and wealth. The academic discipline of statistics in the U.S. claims expertise on data analysis. Yet from the mid-20th century on advances in computationally intensive algorithms for data analysis were developed largely outside of the discipline of statistics. Not until experts on this new paradigm of data analysis diverted resources away from traditional, old paradigm statisticians, was the new paradigm widely accepted in the discipline of statistics, even though a few statisticians had contributed to computationally intensive data analysis all along. This paper’s thesis is that the IP will follow a path into economics similar to that taken by computationally intensive data analysis into statistics, once useful applications of the IP are found and experts on the IP divert resources away from economists. That day is not at hand. There are no applications of the IP to business or government at present. One conceivable application of the IP to market research, small area estimation of personal income distribution, is suggested.

In India, over the years, the progress in women’s nutritional status has been less impressive and remains as a major problem for health policy. The dual burden of nutritional disorder of women in India is posing a serious challenge not only for nutritional policy but also for socio-economic and welfare policies. Therefore, this study assess the determinants of double nutritional disorders among Indian women and consequential within group deviations and between group differentials. Third round of National Family Health Survey (NFHS-3, 2005-06) data, descriptive statistics such as mean and standard deviations and multivariate statistics such as multinomial logistic regression and Multiple Classifications Analysis (MCA) are used for the purpose of this study. The existing socio-economic and behavioural differences and consequential obligations that women face threaten the nutritional balance in India. Obliteration of these anomalies is important to ensure the balanced nutritional status for women in India.

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 is a very draft version of the report "The random-lottery incentive system. Can p~1 experiments deductions be correct?". It is published to extend the abstract of the report. Aczél and Luce emphasized a fundamental question: whether W(1)=1 (whether the Prelec weighting function equals 1 at p=1). A purely mathematical theorem proves W(1)<1. Because of this evident "certain-uncertain" inconsistency, the deductions from the random-lottery incentive experiments, those include the certain outcomes, cannot be unquestionably correct.

The aim of this paper is to make imputation of earnings in observations with missing values in the Encuesta Nacional de Ocupaciones y Empleo (ENOE), and also to analyze a possible bias in human capital estimations from ignoring such missings. We present imputations by two methods, and also a correction for estimations by reweighting observations with reported earnings. The results show differences in human capital estimations on wages and factors related to labor poverty when missing values of earnings are ignored. Differences are acute when measuring labor poverty.

This paper develops the methodology and makes the estimation to measure the importance of the Brazilian supermarket complex to employment and income generation in the Brazilian economy in the 1990’s. To do so, input-output matrices are constructed for the years of 1990, 1995 and 1999, where the supermarket sector is separated from the trade sector. The results show that the supermarket complex was responsible for approximately 6.1% of the total employment in the economy (3.8 million of occupied persons), and for 5% of Brazilian GDP (R$ 46.8 billion in 1999). The study also shows the results disaggregated by economic sector, such that it is possible to know about importance of the links that the supermarket sector has with the other sector in the economy, in terms of employment and income generation.

This report addresses two main topics, R&D and innovation data availability and reliability in Hungary, as well as private sector R&D activities.
Practically all relevant R&D data are collected in Hungary, but there are two major problems. Only a limited set of data are published, and thus made available free of charge. Obviously, this practice prevents detailed analyses, required both for deepening our theoretical understanding of RTDI processes, as well as for policy purposes. Further, the way in which data protection is understood and implemented also poses a challenge from the point of view of theoretical investigations, policy analysis, and ultimately policy-making. For instance, the list of R&D performing companies is not available, and thus it is not possible to conduct even the most elementary calculations, e.g. to establish how many of the top exporters conduct R&D activities. It would be a fairly simple and cheap exercise, and given the weight of exporting firms in the small, open Hungarian economy, a rather pertinent one. It is not possible to analyse the impacts of R&D and innovation on micro-economic performance, either, although these three sets of data (R&D, innovation, and company performance data) are collected – but using different surveys and thus stored in different data sets, which cannot be linked for legal restrictions. In other words, public money is spent on collecting data, which cannot be used for analyses aimed at supporting public policies.
The sectoral case studies confirm the dominant role of foreign-owned firms in RTDI activities. Foreign-owned firms tend to be large, and thus the decisive share of BERD is performed by large enterprises.
Pharmaceuticals industry is the most R&D intensive sector in Hungary. The sectoral research system has been radically restructured during the past fifteen years as foreign pharmaceuticals firms became majority owners in most companies, pursuing global R&D strategies. In Hungary, they focus on the development of generic drugs. Thus, the number of research projects has decreased, but the allocation of R&D expenditures became more efficient.
The most important trends in the world’s medical instruments industry play a determining role in the innovation activities of the Hungarian companies. These trends include the increasing use of IT systems for the support of medical equipment, the revolution of digital imaging equipment and the expansion of the home-use appliances market. Besides research and development of the traditional equipment, Hungarian medical equipment manufacturers proved successful in the development and application of these product families.
Automotive industry has been traditionally less R&D intensive, yet, innovation, R&D and engineering skills are becoming decisive factors of success for automotive firms, too, given the fierce competition, requiring improved products in terms of safety, comfort, and fuel efficiency. Interviews suggest emerging co-operation between automotive firms, on the one hand, and university departments as well as other R&D units, on the other. More recently, some foreign investors are setting up either their in-house R&D units or joint research groups with universities. Besides professional excellence, there is a considerable cost advantage in this field, too. Further, various policy schemes have also been introduced to foster innovation activities in the automotive industry.
