It was shown earlier that the class of algorithmically computable simple games (i) includes the class of games that have finite carriers and (ii) is included in the class of games that have finite winning coalitions. This paper characterizes computable games, strengthens the earlier result that computable games violate anonymity, and gives examples showing that the above inclusions are strict. It also extends Nakamura’s theorem about the nonemptyness of the core and shows that computable simple games have a finite Nakamura number, implying that the number of alternatives that the players can deal with rationally is restricted.

Classify simple games into sixteen "types" in terms of the four conventional axioms: monotonicity, properness, strongness, and nonweakness. Further classify them into sixty-four classes in terms of finiteness (existence of a finite carrier) and computability. For each such class, we either show that it is empty or give an example of a game belonging to it. We observe that if a type contains an infinite game, then it contains both computable infinitegames and noncomputable ones. This strongly suggests that computability is logically, as well as conceptually, unrelated to the conventional axioms.

In this paper we test a particular variant of the (Repulsive) Particle Swarm method on some rather difficult global optimization problems. A number of these problems are collected from the extant literature and a few of them are newly introduced. First, we introduce the Particle Swarm method of global optimization and its variant called the 'Repulsive Particle Swarm' (RPS) method. Then we endow the particles with some stronger local search abilities - much like tunneling - so that each particle can make a search in its neighborhood to optimize itself. Next, we introduce the test problems, the existing as well as the new ones. We also give plots of some of these functions to help appreciation of the optimization problem. Finally, we present the results of the RPS optimization exercise and compare the results with those obtained by using the Genetic algorithm (GA)and/or Simulated annealing (SA) method. We append the (Fortran) computer program that we have developed and used in this exercise.
Our findings indicate that neither the RPS nor the GA/SA method can assuredly find the optimum of an arbitrary function. In case of the Needle-eye and the Corana functions both methods perform equally well while in case of Bukin's 6th function both yield the values of decision variables far away from the right ones. In case of zero-sum function, GA performs better than the RPS. In case of the Perm #2 function, both of the methods fail when the dimension grows larger. In several cases, GA falters or fails while RPS succeeds. In case of N#1 through N#5 and the ANNs XOR functions the RPS performs better than the Genetic algorithm.
It is needed that we find out some criteria to classify the problems that suit (or does not suit) a particular method. This classification will highlight the comparative advantages of using a particular method for dealing with a particular class of problems.

Fokker-Planck and Chapman-Kolmogorov equations for Ito processes with finite memory
McCauley, Joseph L.
C69 - Other
G0 - General
The usual derivation of the Fokker-Planck partial differential eqn. (pde) assumes the Chapman-Kolmogorov equation for a Markov process [1,2]. Starting instead with an Ito stochastic differential equation (sde), we argue that finitely many states of memory are allowed in Kolmogorov’s two pdes, K1 (the backward time pde) and K2 (the Fokker-Planck pde), and show that a Chapman-Kolmogorov eqn. follows as well. We adapt Friedman’s derivation [3] to emphasize that finite memory is not excluded. We then give an example of a Gaussian transition density with 1-state memory satisfying both K1, K2, and the Chapman-Kolmogorov eqns. We begin the paper by explaining the meaning of backward time diffusion, and end by using our interpretation to produce a very short proof that the Green function for the Black-Scholes pde describes a Martingale in the risk neutral discounted stock price.

The Nakamura numbers for computable simple games

C71 - Cooperative Games
The Nakamura number of a simple game plays a critical role in preference aggregation (or multi-criterion ranking): the number of alternatives that the players can always deal with rationally is less than this number. We comprehensively study the restrictions that various properties for a simple game impose on its Nakamura number. We find that a computable game has a finite Nakamura number greater than three only if it is proper, nonstrong, and nonweak, regardless of whether it is monotonic or whether it has a finite carrier. The lack of strongness often results in alternatives that cannot be strictly ranked.

The relative efficiency of UEFA Champions League scorers
Papahristodoulou, Christos
C69 - Other
L83 - Sports ; Gambling ; Restaurants ; Recreation ; Tourism
The mass media, the football supporters and other experts in many countries are often engaged in the ranking of football players. Given the heterogeneity of various leagues or series in which players play, such a comparison is almost impossible. On the other hand, the performance of players in international tournaments, like the FIFA world cup at the national team level, or the UEFA Champions League at the European Club level, can be measured, if we rely on “objective” measures and statistics. Obviously, since various positions of players are evaluated by different criteria, the heterogeneity is still apparent. In this paper we attempt to evaluate a small subset of a team’s players, namely its scorers, using UEFA:s official match-play statistics from the Champions League tournament 2006/07.

we use the linear approximation analysis to state the local stability property and local

A Model of Vacancy Chains as a Mechanism for Resource Allocation
Fioretti, Guido
C69 - Other
J69 - Other
L29 - Other
Vacancy chains can be tracked in any context where a the availability of a desirable resource triggers a cascade of occupations through which the scarce resource flows through different owners. However, under certain conditions vacancy chains, rather than markets or other forms of competition, \emph{determine} the allocation of the resource. This article develops a formal and computational model of vacancy chains as a mechanism for resource allocation in order to find out their properties with respect to organizational forms.
We find that hierarchies with few middle managers are particularly prone to make use of vacancy chains in order to allocate resources that originate at the top, such as employment positions. In fact, vacancy chains often disappear when information is widely available, because information is likely to attract applicants who engage in a competition. Thus, the many middle managers of a thick organization may compete for a resource that originates at the top. On the contrary, organizations that are thick at the bottom and at the top, but thin in the middle, are most likely to regulate resource allocation by means of vacancy chains.

How to chose innovation policies to foster SMEs growth. A region - industry - firm type approach

O38 - Government Policy

O14 - Industrialization ; Manufacturing and Service Industries ; Choice of Technology
This paper aimed at defining a common methodological framework for the evaluation and decision regarding innovation policy instruments, suitable for an international comparative approach. It may be useful in empirical analysis and operative projects.
In particular, the originality of the methodology are the interdisciplinary approach, considering all three main factors affecting innovation systems, especially when thinking to SMEs: the territorial, the technological and the entrepreneurship dimension.
In addition, the methodology has adopted a demand driven approach, based on the precise identification of the needs of services, by analysing them according to different dimensions: industries/technologies, firms and regions.
Thus, the study has adopted a strategic perspective and it indicates that the identification of the strengths, weaknesses, opportunities and threats is facilitating the identification of the actual needs and demand of technology transfer services in a given region.
The methodology is also characterized for having analysed a wide variety of the instruments, which can be used in innovation policies ranging from a top-down, governmental approach to a bottom-up and market approach. This model allows to support decision makers in measuring in a more rigorous and quantitative way the complementarities and the trade-offs of these innovation policy instruments, while aiming to respond to various and interdependent needs, which may have a different priority in various industries, firms and regions.
This is clearly also an effective approach to investigate on regional attractiveness factors and it is a new method of evaluation when applying the model reversely, as well as it is useful to identify most suitable initiatives to apply to enhance the competitiveness of a territory.

In one decade, the CEMAC's countries passed from a banking crisis context to an excess systemic liquidity. In the present survey, we valued the relative levels of technical efficiency of 24 commercial banks of the CEMAC from January 2001 to December 2004 using the DEA method, and searched for the factors of the banking management susceptible to explain these evolutions. The results shows that, on average, under the hypothesis of constant scale outputs, the banks of the CEMAC only produced 36,9% of the quantity of outputs that they could have produced from their resources. While rather supposing the outputs variable, the middle level of technical efficiency settled to 0,693. Of other parts, The explanatory factors of the evolution of the technical efficiency of the banks during this period are: i) the risk of defect; ii) the importance of the Bank, identified by the proportion of the capital stocks on the assets of the banks, iii) the level of the treasury excesses, and iv) the proportion of capital stock in the total of the credits.

A viability theory approach to a two-stage optimal control problem

C61 - Optimization Techniques ; Programming Models ; Dynamic Analysis
A two-stage control problem is one, in which model parameters (“technology”) might be changed at some time. An optimal solution to utility maximisation for this class of problems needs to thus contain information on the time, at which the change will take place (0, finite or never) as well as the optimal control strategies before and after the change. For the change, or switch, to occur the “new technology” value function needs to dominate the “old technology” value function, after the switch. We charaterise the value function using the fact that its hypograph is a viability kernel of an auxiliary problem and study when the graphs can intersect and hence whether the switch can occur.
Using this characterisation we analyse a technology switching problem.

L86 - Information and Internet Services ; Computer Software
The paper deals with business potential analysis based on the data published by Czech
Statistic Authority (SÚ). It shows that the infrastructure state of the art even in small Czech
companies enables to expand ERP and CRM systems, trading over Internet, Supply Chain
Management and other new trends. Internet security is here of greatest importance, however it
cannot be seen as major obstacle for new trading methods. The greatest challenge identified is
the process and workflow optimization. To streamline workflow the document management
supporting nearly seamless integration crossover the functional areas is of greatest
importance. Moreover, process optimization can run into difficulties due to cross-organization
functionalities of new IT architecture concepts like Service Oriented Architecture, WEB2
concepts and other methods and means. In this paper the value flow approach is shortly
mentioned as an alternative to process modeling and workflow approach. Value oriented
methods can overcome the process oriented approach limitations.

This paper estimates the technical efficiency of a set of Argentinean firms in the electric distribution sector for the period 1994-2001. The efficiency measurement involves the application of two methods: one non-parametric and the other parametric. The first one is DEA and the second one is the distance functions. Additionally, we focus on the construction of the efficient frontier for both methods. We present the consistency conditions for both methodologies in order to test weather both of them tend to give the same answer to the question of the efficiency measurement of the firms in the sample.

This paper offers a quantification of price differentials not explained by tariff policy and the assessment of efficiency costs burned on different economic agents involved in textile products trade between Argentina (exporter) and Brazil (domestic producer). Simulations are carried out to show the effects of the distortion of price differentials, considered like non tariff barriers or a set of them and others obstacle to trade. From the removal of non tariff barriers results that consumers and exporters obtain grater consumer surplus and profits, respectively, while domestic producers loose part of their producer surplus. Consumers and exporters are better because of changes in terms of trade; in some products consumers obtain graters benefits than exporters and vice versa. Likewise, changes in elasticities (direct elasticity of supply and demand) were simulated to observe distortions in previous results.

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 article presents an agent-based model of an Italian textile district where thousands of small firms specialize in particular phases of fabrics production.
It is an empirical and methodological model that reconstructs the communications between firms when they arrange production chains. In their turn, production chains reflect into road traffic in the geographical areas where the district extends. The reconstructed traffic exhibits a pattern that has been observed, but not foreseen, by policy makers.

Computability of simple games: A complete investigation of the sixty-four possibilities

Classify simple games into sixteen "types" in terms of the four conventional axioms: monotonicity, properness, strongness, and nonweakness. Further classify them into sixty-four classes in terms of finiteness (existence of a finite carrier) and algorithmic computability. For each such class, we either show that it is empty or give an example of a game belonging to it. We observe that if a type contains an infinite game, then it contains both computable ones and noncomputable ones. This strongly suggests that computability is logically, as well as conceptually, unrelated to the conventional axioms.

Globalization poses special challenges for economies in transition, particularly those which
have been slow to reform systems of administered prices. Such allocation mechanisms now
encounter significant friction from external market forces, and it is vital for policymakers to
better anticipate the incidence of external price transmission. In this paper, we propose a
novel variation of multiplier decomposition methods; make use of an up-to-date social
accounting matrix (SAM) for Vietnam; and demonstrate how this kind of information can
help identify adverse incentive and wealth effects that might undermine reform and structural
adjustments efforts in this important emerging Asian economy.

This paper analyses how European football clubs’ current value and debt levels influence their performance. The Simar and Wilson (J Econometrics, 136: 31–64, 2007) procedure is used to bootstrap the data envelopment analysis DEA scores in order to establish the influence of football clubs’ current value and debt levels on their obtained efficiency performances. The results reveal that football clubs’ current value levels have a negative influence on their performances, indicating that football clubs’ high value doesn’t ensure higher performance. At the same time, the empirical evidence suggests that there is no influence associated of football clubs’ debt to their efficiency levels.

C14 - Semiparametric and Nonparametric Methods: General

This paper applies a probabilistic approach to investigate how the top European football clubs’ current value and debt levels influence their performance. Specifically, a bootstrapped conditional data envelopment analysis (DEA) is used in order to measure the effect of football clubs’ current value and debt levels on their obtained efficiency performances. The results indicate that football clubs’ current value levels have a positive influence up to a certain point. But as the current value increases the effect is neutral to football clubs’ performance. At the same time, the empirical evidence suggests that there is no influence on football clubs’ efficiencies associated with lower and medium football clubs’ debt levels while higher debt levels appear to have a direct negative effect.

This paper by analyzing the two popular methodologies of productivity measurement provides an example that illustrates the differences when adopting the two methodologies. Furthermore, under the restriction of constant returns to scale raises some methodological issues regarding the theory of productivity measurement using the Malmquist Productivity Index and Malmquist Total Factor Productivity Index. Furthermore by using an illustrative example under the restriction of constant returns to scale the study indicates that the two indexes produce similar results. However, the differences observed are determining the choice of the methodology adopted when measuring productivity.

This paper demonstrates an evaluation of 71 developed and under-developed countries’ biodiversity performance using a methodological framework based to the new advances of Data Envelopment Analysis (DEA). By using conditional DEA, bootstrapping and kernel density estimations, efficiency levels of 71 countries are compared and analyzed. In such a way the paper by modelling and measuring countries’ biodiversity performance analyses whether the countries environmental policies have been used efficiently in order to enhance biodiversity. Our empirical results indicate that there are major inefficiencies among the 71 countries in terms of their biodiversity performances which have been negatively influenced by their higher levels of population and of GDP per capita.

Rapid development of technologies and their penetration into all sectors generates a wide range of streamlining of production and trade processes. Electronic commerce is the area in which information and communication technology (ICT) is an essential and indispensable element. It is based on the use of e-commerce systems. An e-commerce system combines several parts consisting of customers, suppliers (sellers, dealers, producers, businessmen, etc.), the web server (web interface), the information system (ERP, CRM, the database system), the payment system, the dispatch system and the legislature itself. All these subsystems must be managed both at the operational level and in terms of the whole e-commerce system. E-commerce systems are tools meant to support the supply chain (SC), the quality of which as well as other parts of the e-commerce system largely depend on management processes representing supply chain management (SCM). The optimal way to ensure the success of SCM is to use the methods of modelling and simulation based on appropriate models and mathematical representation of a real SC. Such models are constructed with the use of process and value-chain oriented approaches or based on the concept of multi-agent systems. Different types of models in conjunction with a suitable mathematical representation allow us to perform the simulation process which outputs can help managers make suitable decisions. The paper aims at presenting contemporary approaches to the supply chain modelling within e-commerce systems. Moreover, the case study emphasized hereby is oriented to present the sample simulation approach in order to find the optimal allocation of resources which are meant to minimize shipping costs.

This paper elaborates on a method of measuring regional specialization and examines the trend of regional specialization in China, 1987 - 2007. It constructs a simple coefficient incorporating the effect of regional industrial scale, based on location quotients, and then measures the regional specialization of China using official statistical data. The results indicate a remarkable increase in China’s overall regional specialization during this time, as well as obvious regional and industrial differences, i.e., that the regional specialization of eastern coastal China is relatively less than that of the inland. Findings further demonstrate that special-resource-dependent industries are concentrated in regions with resource endowment, whereas industries with strong technical barriers are mainly located in regions with strong research and innovation ability.

This paper considers the approach to specification and modeling of transport influence on spatial allocation of economy, which is essentially new for economics. By applying the concept of fiber bundle, a general model of spatial allocation of market with regard to transport costs is developed. Corresponding mathematical formulation of model equilibrium condition and transition dynamics is stated based on the principle of least action and gauge invariance. Further development of obtained theoretical results within the framework is reviewed.

This paper by applying a sporting production function evaluates 229 professional tennis players’ career performance. By applying Data Envelopment Analysis (DEA) the paper produces a unified measure of nine performance indicators into a single career performance index. In addition bootstrap techniques have been applied for bias correction and the construction of confidence intervals of the efficiency estimates. The results reveal a highly competitive environment among the tennis players with thirty nine tennis players appearing to be efficient.

This set of three volumes argues that the mind – human consciousness – may be measured by considering mathematically the aggregate of that consciousness, i.e. social history. From this beginning theme of discussion three questions must arise.
1. How might this measurement be made?
2. Of what value is this measurement? and
3. How does this measurement affect our present understanding
of the reality in which we live?
Each of these three volumes attempts to provide answers to one of these questions.

I argue that a form of consciousness may be found in American economic history, one which is both mathematically demonstrable and important. In this book I present a model of economic and political growth based upon systematic addition.
We begin with a philosophic model of trade (pp. 34-46);
aggregate this model over the course of year to state the real Gross National Product of the United States and its relationship to the rate of employment (pp. 47-62);
aggregate this model over the course of many years to find the growth of the United States stated as a natural “14-year octave” within real GNP data (pp. 63-91);
multiply this octave times two to find the 28-year natural rate of price fluctuation (pp. 92-112); and
multiply this octave times four to find the 56-year natural rate of political change (p. 92-112).
The final model (pp. 113-136) is the larger “fractal” of the model of trade which begins these essays, in essence demonstrating that the United States “trades” values over a period of time in much the same way the individual citizen trades goods and services for money on a personal basis.

The paper discusses implementation of a research that is aimed at development of a simulation model which would allow analyzing different development strategies of the third generation university. Small countries’ universities have limits of growth. The problem can be solved with a new approach to university role. The third generation defines university as innovation generation, transfer and implementation center, while maintaining the traditional university functions. The 3G university activities change number of innovative companies in the country. With growth of the number of innovative companies, potential researches and innovation customers’ amount grow. With time the amount of conducted research and developed innovative products growth. Innovative products and technologies is the basis of university competitiveness in the 21st century. Universities must develop, accumulate, implement and get benefits from innovative products and technologies.

The formation of the European Union (EU) is the one of the biggest political – economic events of the last 50 years. The aim of this study is to develop EU economy functioning system dynamic model. Main research method is system dynamics. General scheme of EU economy system dynamic model is shown. Implementing the model in practice, new EU member economic integration model in EU is developed. Model is tested only for one EU country, Latvia. Results of the paper show failure of the mechanism of EU operations. The available mechanism contradicts EU principles; it doesn't promote the cohesion in European Union, but quite opposite - leads to solving problems of well-developed EU countries at the expense of developing countries. In the given conditions the example of Latvia shows that there is no possibility to overcome the system crisis. These circumstances specify necessity of changes in EU internal migratory policy, changes in principles of developing countries’ support in EU, and changes in distribution of EU means, taking into account internal migration.

A Test of the Stable Paretian Hypothesis for the Distribution of Income
Dale, Charles
C40 - General
C69 - Other
J1 - Demographic Economics
Mandelbrot has recently proposed that the distribution of income might be described by a class of mathematical processes called Stable Paretian functions. These functions have many of the desirable properties of Gaussian distributions but they have infinite variance, which has implications for making projections. Since Mandelbrot’s hypothesis applies only to very high income families, his ideas are of interest to the Army because children in high income families have a low propensity to enlist in the military, so an increasingly affluent population could have an effect on Army recruiting. This paper concludes that the distribution of income cannot be adequately described by either lognormal or Stable Paretian distributions. So, forecasters of the distribution of income do not need to deal with infinite variances, and may assume only that the underlying distributions are stationary.

This paper considers the approach to specification and modeling of transport influence on spatial allocation of economy, which is essentially new for economics. By applying the concept of fiber bundle, a general model of spatial allocation of market with regard to transport costs is developed. Corresponding mathematical formulation of model equilibrium condition and transition dynamics is stated based on the principle of least action and gauge invariance. Further development of obtained theoretical results within the framework is reviewed.

Multinomial Probit Models of Military Enlistments: A Comparison of Alternative Solution Algorithms
Dale, Charles
C40 - General
C69 - Other
The increasing popularity of qualitative response models in recent years has led to the development of sophisticated algorithms to solve them. The relative efficiency and accuracy of various algorithms is a subject of considerable importance to the Army, because the results derived from probit models may be used increasingly by Army decision makers. This paper compares the accuracy and cost of several types of algorithms used to model the decision whether or not to enlist in the military. The paper concludes that econometricians who undertake analyses using large databases for cross-sectional studies will gain very little by using some of the recently developed algorithms such as BHHH. These new methods represent elegant and impressive theoretical achievements, but in practice they do not justify their enormous cost.

The paper demonstrates possibilities of both convergence to the steady state and emergence of stable growth cycles around it in a simple macrodynamic model of debt-financed investment-led growth. The growth cycles are robust and are generated endogenously, either due to the existence of a supercritical Andronov-Hopf bifurcation, or due to the global stability condition through an application of the Poincaré-Bendixson theorem. The emergence of multiple limit cycles is also observed under certain conditions. The possibility of a deterioration of financial variables during a boom, with the resulting financial crisis providing an endogenous ceiling to a business cycle is examined in this context.

Using a macroeconomic example, the paper proposes an algorithm to symbolically construct the topological normal form of Andronov-Hopf bifurcation. It also offers a program, using the Computer Algebra System `Maxima', to apply this algorithm. In case the limit cycle turns out to be unstable, the possibilities of the dynamics converging to another limit cycle is explored.

Dominant, weakly stable, uncovered sets: properties and extensions

Twelve sets, proposed as social choice solution concepts, are compared: the core, five versions of the uncovered set, two versions of the minimal weakly stable sets, the uncaptured set, the untrapped set, the minimal undominated set (strong top cycle) and the minimal dominant set (weak top cycle). The main results presented are the following.
A criterion to determine whether an alternative belongs to a minimal weakly stable set is found. It establishes the logical connection between minimal weakly stable sets and covering relation.
In tournaments and in general case it is determined for all twelve sets, whether each two of them are related by inclusion or not.
In tournaments the concept of stability is employed to generalize the notions of weakly stable and uncovered sets. New concepts of k-stable alternatives and k-stable sets are introduced and their properties and mutual relations are explored.
A concept of the minimal dominant set is generalized. It helps to establish that in general case all dominant sets are ordered by strict inclusion. In tournaments the hierarchies of the classes of k-stable alternatives and k-stable sets combined with the system of dominant sets constitute tournament’s structure (“microstructure” and “macrostructure” respectively). This internal structure may be treated as a system of reference, which is based on difference in degrees of stability.

Recent financial crises and especially large corporate bankruptcies, have led bank managements and financial authorities to follow and monitor both financial and real sector risks, and to focus on firm failures. Bank of International Settlements, has therefore, taken the decision to include the necessity for banks to employ internal rating systems among BASEL II criteria. Thus, risk assessment and internal rating systems criteria would be made operational by the individual European Union banking systems, by the end of 2007, and January 2008 in Turkey, at the latest.
Financial and operational information of the firms, makes up the input to the risk analysis. This information can be aggregated to portray the sectoral trends, and/or focused upon on a firm basis to understand firms’ financial behaviours. Finance theory summarizes firms’ risks under financial distress and firm failure. There have been a myriad of works under these two headings, particularly in the United States, after the Great Depression. While early studies have focused upon the differences in the financial ratios of financially sound and failed firms, especially with the advances in computing capacity, the last two decades have witnessed an increasing use of machine learning methods in the failure prediction. Therefore, machine learning methods can be considered as having great potential in failure prediction and being good candidates as decision aids for policy-making.
This study considers financial distress and firm failure on theoretical grounds, gives a compact but elaborate explanation of machine learning schemes, and analyzes the results of these schemes run with data obtained from the database of Real Sector Data Division of the Central Bank. Cost sensitive learning was given special attention in the analysis.

This paper demonstrates the diverse dynamical possibilities arising out of a simple macroeconomic model of debt-financed investment-led growth in the presence of interest rate rules. We show possibilities of convergence to steady state, growth cycles around it as well as various complex dynamics. We investigate whether, given this framework, the financial sector can provide endogenous bounds to an otherwise unstable system. The effectiveness of monetary policy in the form of a Taylor-type interest rate rule targeting capacity utilization is examined under this context.

Using the Andronov-Hopf bifurcation theorem and the Poincaré-Bendixson Theorem, this paper explores robust cyclical possibilities in a generalized Kolmogorov-Lotka-Volterra class of models with positive intraspecific cooperation in the prey population. This additional feedback effect introduces nonlinearities which modify the cyclical outcomes of the model. Using an economic example, the paper proposes an algorithm to symbolically construct the topological normal form of Andronov-Hopf bifurcation. In case the limit cycle turns out to be unstable, the possibilities of the dynamics converging to another limit cycle is explored.

A Social Accounting Matrix of Mexico for the Year 2000
Núñez, Gaspar
C67 - Input-Output Models
C69 - Other
The usefulness of a Social Accounting Matrix (SAM) has been solidly established, both, as a major element for economic analysis and policy studies, and for designing and
implementing multisectoral models. In this paper we present a Social Accounting Matrix of Mexico for the year 2000, documenting a detailed methodology used for its
construction. It is shown that, with an Input Output Table of Mexico for the year 2000 as a basis, and using available information from the System of National Accounts of
Mexico, it is possible to build a balanced macro SAM, and then a consistent micro SAM, without resorting to any of the several balancing and estimation procedures developed
for the cases in which incomplete, and/or inconsistent information, prevents construction of a fully documented SAM. Therefore, this transparent SAM can be used
(modified and/or extended) to apply a wide array of analytical methodologies to study a wide variety of policy issues.

Recent natural and man-made disasters underscore the need of a resilient and agile disaster relief supply chain to mitigate the damages and save people’s lives. Optimization and simulation modeling have become powerful and useful tools to help decision makers tackle problems related to disaster relief supply chain. This paper reviews optimization and simulation models used in the field of disaster relief supply chain. We review the literature of the facility location optimization problems of disaster relief supply chain under different types of disastrous events. We review the literature of simulation models on supply chain design and disaster relief distribution operations. Finally, we propose two future research directions for disaster relief supply chain modeling.

Choosing put option parameters based on quantiles from the distribution of portfolio value

C69 - Other
D81 - Criteria for Decision-Making under Risk and Uncertainty
G00 - General
G11 - Portfolio Choice ; Investment Decisions
This paper explores how a put option changes the probability distribution of portfolio value. The paper extends the model introduced in Bell (2014) by allowing both the quantity and strike price to vary. I use the 5% quantile from the portfolio distribution to measure riskiness and compare different put options. I report a so-called ‘quantile surface’ that shows the quantile across different combinations of quantity and strike price. I find that it is possible to maximize the quantile by purchasing a put with quantity equal to one and strike deep in the money; however, the distribution with such a put option collapses to a single point because the option hedges all variation in stock price. This result is analogous to full-insurance in insurance economics, but has practical limitations. The quantile surface also shows that certain put options will decrease the quantile, which is equivalent to increasing the riskiness of the portfolio, and leads me to ask: what return will an investor receive in return for bearing that extra risk? I find that one such put option will cause the distribution to have an asymmetric shape with positive skewness, which is interesting to some speculators.

The article explores new actual problem of investment processes’ coordination modeling at regional level. The research is driven to develop conception and complex of models to coordinate investments. Methods and tools of their implementation under current economic conditions at regional level in Ukraine are examined as well. Conception of coordination of regional investment processes that provide effective investment resources allocation including different level budget and off-budget resources is proposed. Article also develops complex of economic and mathematical models that promote coordination of investment processes and regional development programs. Structure of DSS in the field of investments management is improved.
The outcome of implementation the research results in Donetsk Regional State Administration is improvement of investment processes management system that led to better economic efficiency of regional investment projects.

VaR Risk Measures versus Traditional Risk Measures: an Analysis and Survey

The article presents an analysis and survey regarding the validity of VaR risk measures in comparison to traditional risk measures. Individuals are assumed to either maximize their expected utility or possess a lexicographic utility function. The analysis is carried out for generally distributed functions and for the normal and lognormal
distributions. The main conclusion is that although VaR is an inadequate measure within the expected utility framework, it is at least as good as other traditional risk measures. Moreover, it can be improved by modified versions such as
the Accumulated-VaR (Mean-Shortfall) Assuming a lexicographic expected utility strengthens the argument for using AVaR as a legitimate risk measure especially in
the case of a regulated firm.

The aim of this article is to present a new tool for assessing TU-game based on a matrix representation. We focus on TU-games with coalition structures and provide a general matrix form of TU-game. We shed light on some useful properties of the matrix representation of TU-game and the general form obtained is applied to describe the
representation for some classical TU-game. The facilities provided by such a representation are used to characterize subclasses of Linear Efficient and Symmetric (LES) values.

This paper elaborates on a method of measuring regional specialization and examines the regional specialization trends in China, 1987 - 2007. It constructs a coefficient incorporating the effects of regional industrial scale based on location quotients, and then measures China’s regional specialization using official statistical data. The results indicate a remarkable increase in China’s overall regional specialization during this time, as well as obvious regional and industrial differences, i.e., that the regional specialization of China’s eastern coast is relatively less than that of areas further inland. Findings further demonstrate that special-resource-dependent industries are concentrated in regions with resource endowment, whereas industries with strong technical barriers are located in regions possessing strong research and innovation resources.

Shock Diffusion in Regular Networks: The Role of Transitive Cycles

We study how the presence of transitive cycles in the interbank network affects the extent of financial contagion. In a regular network setting, where the same pattern of links repeats for each node, we allow an external shock to propagate losses through the system of linkages (interbank network). The extent of contagion (contagiousness) of the network is measured by the limit of the losses when the initial shock is diffused into an infinitely large network. This measure indicates how a network may or may not facilitate shock diffusion in spite of other external factors.
Our analysis highlights two main results. First, contagiousness decreases as the length of the minimal transitive cycle increases, keeping the degree of connectivity (density) constant. Second, as density increases the extent of contagion can decrease or increase, because the addition of new links might decrease the length of the minimal transitive cycle. Our results provide new insights to better understand systemic risk and could be used to build complementary indicators for financial regulation.

In post-Keynesian literature, Hein (2012a) was the first to incorporate financialization as an influential positive determinant of the rate of technological change. However, financialization is more like a two-edged sword which can affect technological progress negatively as well. We capture both the positive as well as the negative effect of financialization on technological progress which encapsulates the possibility of multiple equilibria. In
analyzing the long run of the model we endogenize the financialization parameter as well. We then show how two subsystems (technological progress and financialization dynamics) when interact with each other, can produce instability and cycles for the whole system. We show that under certain circumstances, higher speed of diffusion of technological innovation, more regulated financial markets, and higher intra-class competition among firms are desirable for stabilizing the economy. Finally, we provide some policy
prescriptions for the same.

In this paper we try to build a statistical ensemble to describe a cryptocurrency-based system, emphasizing an "affinity" between the system of agents trading in these currencies and statistical mechanics. We focus our study on the concept of entropy in the sense of Boltzmann and we try to extend such a definition to a model in which the particles are replaced by N agents completely described by their ability to buy and to sell a certain quantity of cryptocurrencies. After providing some numerical examples, we show that entropy can be used as an indicator to forecast the price trend of cryptocurrencies.

Reducing incentive constraints in bidimensional screening

This paper studies screening problems with quasilinear preferences, where agents' private information is two-dimensional and the allocation instrument is one-dimensional. A pre-order in the set of types is defined comparing types by their marginal valuation for the instrument, which allows reducing the incentive compatibility constraints that must be checked.
With this approach, the discretized problem becomes computationally tractable. As an application, it is numerically solved an example from Lewis and Sappington

Valoración de derivados europeos con mixtura de distribuciones Weibull

C15 - Statistical Simulation Methods: General
C69 - Other
G13 - Contingent Pricing ; Futures Pricing
The Black-Scholes valuation model for European options is widely used in the stock markets due to its easy implementation. However, the model is not accurate for different assets whose dynamics do not follow those of a lognormal distribution, so it is necessary to investigate new distributions to price different options written on various underlying assets. Several researchers have worked on new valuation formulas, assuming different distributions for either the price of the underlying asset or for the return of the same. This paper presents two methods for European derivatives valuation, one of them, modifying the formula using a Weibull distribution with two parameters given by Savickas (2002) adding two new parameters (scale and location), and another assuming that the underlying distribution is a Weibull mixture. Comparisons are also presented with these models against existing models such as the Black-Scholes model and Savickas with a simple Weibull distribution.
