Book Synopsis Degeneracy Graphs and Simplex Cycling by : Peter Zörnig
Download or read book Degeneracy Graphs and Simplex Cycling written by Peter Zörnig and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many problems in economics can be formulated as linearly constrained mathematical optimization problems, where the feasible solution set X represents a convex polyhedral set. In practice, the set X frequently contains degenerate verti- ces, yielding diverse problems in the determination of an optimal solution as well as in postoptimal analysis.The so- called degeneracy graphs represent a useful tool for des- cribing and solving degeneracy problems. The study of dege- neracy graphs opens a new field of research with many theo- retical aspects and practical applications. The present pu- blication pursues two aims. On the one hand the theory of degeneracy graphs is developed generally, which will serve as a basis for further applications. On the other hand dege- neracy graphs will be used to explain simplex cycling, i.e. necessary and sufficient conditions for cycling will be de- rived.

Available in PDF, EPUB and Kindle. Book excerpt: The 9th Belgian-French-German Conference on Optimization has been held in Namur (Belgium) on September 7-11, 1998. This volume is a collection of papers presented at this Conference. Originally, this Conference was a French-German Conference but this year, in accordance with the organizers' wishes, a third country, Belgium, has joined the founding members of the Conference. Hence the name: Belgian French-German Conference on Optimization. Since the very beginning, the purpose of these Conferences has been to bring together researchers working in the area of Optimization and partic ularly to encourage young researchers to present their work. Most of the participants come from the organizing countries. However the general ten dancy is to invite outside researchers to attend the meeting. So this year, among the 101 participants at this Conference, twenty researchers came from other countries. The general theme of the Conference is everything that concerns the area of Optimization without specification of particular topics. So theoretical as pects of Optimization, in addition to applications and algorithms of Opti mization, will be developed. However, and this point was very important for the organizers, the Conference must retain its convivial character. No more than two parallel sessions are organized. This would allow useful contacts between researchers to be promoted. The editors express their sincere thanks to all those who took part in this Conference. Their invaluable discussions have made this volume possible.

Book Synopsis Microsimulation Modelling of the Corporate Firm by : Frank W. van Tongeren
Download or read book Microsimulation Modelling of the Corporate Firm written by Frank W. van Tongeren and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: My interest in microsimulation started to develop when I was exposed to the works of Guy Orcutt and his associates on microsimulation of households in the USA, and those of Gunnar Eliasson and his associates on simulatio~ of Swedish firms. Their approaches promised the exciting possibility to represent an by simulating the behaviour of individual microeconomic entire economic system units on a computer. The construction of a large scale microsimulation model seemed to be a worthwhile adventure which could yield much more detailed results than existing models. It was also evident that microsimulation of firms is a relatively underdeveloped area, in spite of the large number of operational microsimulation models of households in the USA and Europe. Developing the computer implementation has been an integral part of the research. Translating initially vague ideas into mathematical formulae and subsequently into a structured computer language provides a testing ground for 10Bical consistency of ideas. When writing this book I have purposefully abstained from describing the computer program and dedicated solution algorithms. The reason is that the book is primarily directed towards readers interested in economics and therefore uses the language of economics and not that of computer science. The simulation model has been programmed for the personal computer in Turbo Pascal. Sophisticated memory management techniques have lifted constraints on the number of firms which can be simulated on the PC.
Book Synopsis Equity, Efficiency and Evolutionary Stability in Bargaining Games with Joint Production by : Manfred Königstein
Download or read book Equity, Efficiency and Evolutionary Stability in Bargaining Games with Joint Production written by Manfred Königstein and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Result 1.10 Simple equity standards were superior to more complex ones, even though the latter might be economically more relevant. Result 1.11 Equity based on quantity (input) and return (output) was most successful and received a hit rate of almost i within a range of 10%, i.e., within a distance of ±5% of the predicted share. Result 1.12 A substantial share of observations is consistent with egalitarian considerations. 1.7 Summary The study investigates the predictive power of equity theory and strategic concepts within ultimatum bargaining with advance produc tion. This is different from many other experimental studies on non cooperative bargaining games, since usually the ressource to be dis tributed between the subjects is given by the experimenter. Here, the "pie" is produced via joint production effort. This scenario is more general than bargaining without production, and we think it is more natural as well. The description of the raw data showed that the production choices are considerably dispersed, but nevertheless systematically biased to ward the respective player's efficient production level. The distribu tions of demanded return shares and demanded surplus shares partly replicated findings of other studies; namely, a low percentage of high demands and a considerable proportion of equal surplus splits. But, they also indicate that "advance production" compared to "no pro duction" should be considered an important treatment in studies on ultimatum bargaining.
Book Synopsis Silverman’s Game by : Gerald A. Heuer
Download or read book Silverman’s Game written by Gerald A. Heuer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: The structure of a Silverman game can be explained very quickly: Each of two players independently selects a number out of a prede termined set, not necessarily the same one for both of them. The higher number wins unless it is at least k times as high as the other one; if this is the case the lower number wins. The game ends in a draw if both numbers are equal. k is a constant greater than 1. The simplicity of the rules stimulates the curiosity of the the orist. Admittedly, Silverman games do not seem to have a direct applied significance, but nevertheless much can be learnt from their study. This book succeeds to give an almost complete overview over the structure of optimal strategies and it reveals a surprising wealth of interesting detail. A field like game theory does not only need research on broad questions and fundamental issues, but also specialized work on re stricted topics. Even if not many readers are interested in the subject matter, those who are will appreciate this monograph.

Book Synopsis Interaction and Market Structure by : Domenico Delli Gatti
Download or read book Interaction and Market Structure written by Domenico Delli Gatti and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of essays which examine how the properties of aggregate variables are influenced by the actions and interactions of heterogenous individuals in different economic contexts. The common denominator of the essays is a critique of the representative agent hypothesis. If this hypothesis were correct, the behaviour of the aggregate variable would simply be the reproduction of individual optimising behaviour. In the methodology of the hard sciences, one of the achievements of the quantum revolution has been the rebuttal of the notion that aggregate behaviour can be explained on the basis of the behaviour of a single unit: the elementary particle does not even exist as a single entity but as a network, a system of interacting units. In this book, new tracks in economics which parallel the developments in physics mentioned above are explored. The essays, in fact are contributions to the analysis of the economy as a complex evolving system of interacting agents.

Book Synopsis Dynamic Macroeconomics with Imperfect Competition by : Leo Kaas
Download or read book Dynamic Macroeconomics with Imperfect Competition written by Leo Kaas and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis was stimulated throughout the time of my participation in a research project on Dynamic Macroeconomics, supported by the German Research Foundation (DFG). The starting point was the central question of how to integrate price setting firms in a dynamic disequilibrium model. Almost all recent literature on imperfect competition in macroeconomics applies the objective demand approach by assuming that firms know the true demand curve they are faced with. While this approach can be ap plied in temporary monetary equilibrium models, it proves inadequate for formulating price adjustment in a dynamic disequilibrium model, where it has to be replaced by the concept of subjective demand. Based on this distinction, the thesis starts out with a comparison of the concepts of subjective and objective demand in an abstract framework and surveys the literature on general equilibrium theory with imperfect competition. The objective demand approach is criticized not only on the grounds of its strong rationality requirements and existence problems, but also by the observation that it cannot be applied successfully to characterize determinate rational expectations equilibria in intertemporal macroeco nomics. Finally, price setting firms using subjective demand functions are integrated in a dynamic disequilibrium model in order to study mo nopolistic and oligopolistic price adjustment.

The spectrum covered by information economics today ranges from Stigler's search theory4 to industrial economics, including oligopoly theory, innovation, as well as research and develop 5 ment. However, the area information economics is most closely connected with is the theory of optimal contracts, mainly ana 6 lyzed in principal-agent models. Contract theory deals primar ily with the question of how optimal arrangements (contracts) for the purchase and sale of commodities and services between two or more agents should be structured. In these models, it is often assumed that the parties to the contract are informed differently or asymmetrically about relevant variables (e. g. the health of one party in the case of insurance contracts, or the effort in relation to employment contracts). As a result of this asymmetric in formation, phenomena such as moral hazard, adverse selection, signaling, and screening may arise. Frequently, results from con tract theory are referred to when making statements about the effects of asymmetric information on an economy. Models of this kind are often used to explain phenomena such as fixed wages or unemployment, among others. 7 However, such conclusions must be treated with caution for two reasons. In the first place, in these models, a contract (explicit or implicit) is determined by the solution of an optimization prob lem.
Book Synopsis Nonlinear Dynamics in Economics by : Bärbel Finkenstädt
Download or read book Nonlinear Dynamics in Economics written by Bärbel Finkenstädt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: 1. 1 Introduction In economics, one often observes time series that exhibit different patterns of qualitative behavior, both regular and irregular, symmetric and asymmetric. There exist two different perspectives to explain this kind of behavior within the framework of a dynamical model. The traditional belief is that the time evolution of the series can be explained by a linear dynamic model that is exogenously disturbed by a stochastic process. In that case, the observed irregular behavior is explained by the influence of external random shocks which do not necessarily have an economic reason. A more recent theory has evolved in economics that attributes the patterns of change in economic time series to an underlying nonlinear structure, which means that fluctua tions can as well be caused endogenously by the influence of market forces, preference relations, or technological progress. One of the main reasons why nonlinear dynamic models are so interesting to economists is that they are able to produce a great variety of possible dynamic outcomes - from regular predictable behavior to the most complex irregular behavior - rich enough to meet the economists' objectives of modeling. The traditional linear models can only capture a limited number of possi ble dynamic phenomena, which are basically convergence to an equilibrium point, steady oscillations, and unbounded divergence. In any case, for a lin ear system one can write down exactly the solutions to a set of differential or difference equations and classify them.

This book was released on 2000-05-26 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past two decades, the consideration of mUltiple objectives in modeling and decision making has grown by leaps and bounds. The nineties in particular have seen the emphasis shift from the dominance of single-objective modeling and optimization toward an emphasis on multiple objectives. The proceedings of this Conference epitomize these evolutionary changes and contribute to the important role that the tield of multiple criteria decision making (MCDM) now plays in planning, design, operational, management, and policy decisions. Of special interest are the contributions of MCDM to manufacturing engineering. For example, it has recently been recognized that optimal, single-objective solutions have often been pursued at the expense of the much broader applicability of designs and solutions that satisfy multiple objectives. In particular, the theme (MCDM and Its Worldwide Role in Risk-Based Decision Making) of the XIVth International Conference on Multiple Criteria Decision Making (Charlottesville, Virginia, USA, June 8-12, 1998) represents the growing importance of risk-cost-benefit analysis in decision making and in engineering design and manufacturing. In such systems, minimizing the of rare and extreme events emerges as an essential objective that risk complements the minimization of the traditional expected value of risk, along with the objectives attached to cost and performance. These proceedings include forty-five papers that were presented at the Conference. A variety of techniques have been proposed for solving multiple criteria decision-making problems. The emphasis and style of the different techniques largely reflect the fields of expertise of their developers.
Book Synopsis Computer-Aided Transit Scheduling by : Joachim R. Daduna
Download or read book Computer-Aided Transit Scheduling written by Joachim R. Daduna and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: This proceedings volume consists of papers presented at the Sixth International Workshop on Computer-Aided Scheduling of Public Transpon, which was held at the Fund~lio Calouste Gulbenkian in Lisbon from July 6th to 9th, 1993. In the tradition of alternating Workshops between North America and Europe - Chicago (1975), Leeds (1980), Montreal (1983), Hamburg (1987) and again Montreal (1990), the European city of Lisbon was selected as the venue for the Workshop in 1993. As in earlier Workshops, the central theme dealt with vehicle and duty scheduling problems and the employment of operations-research-based software systems for operational planning in public transport. However, as was initiated in Hamburg in 1987, the scope of this Workshop was broadened to include topics in related fields. This fundamental alteration was an inevitable consequence of the growing demand over the last decade for solutions to the complete planning process in public transport through integrated systems. Therefore, the program of this workshop included sections which dealt with scheduling problems and computerized systems for operational planning as well as sections on network planning and data management.
