Increasing efficiency in generating national income and improving equity in its distribution among economic agents is at the forefront of priorities of most modern economies.

This study presents an econometric modelling approach to analyzing macroeconomic disequilibria, focusing on the market for goods and labour and the spillovers between these markets transmitted through the decisions of companies during the production cycle.

Second, we review different strands of the economic literature in order to show that most of the literature has so far exclusively concentrated either on fmancial market dynamics or on flScal policy issues.

Since inventory chains are "conservative" systems analogous to a traffic stream, and since traffic flow models exhibit similar effects (the instability of automobile platoons and of certain numerical methods being two nota ble examples)' I suspected that traffic flow theory might shed some light on the puzzle.

This is an analysis of long run effects of inflation on real activity. It surveys the theoretical and empirical literature, and introduces a monetary version of an overlapping generations economy with production and a single outside asset as a base model as a framework for the debate.

My recent book Capital and Knowledge (Zhang, 1999a) shows how separate economic theories such as the Marxian economics, the Keynesian economics, the general equilibrium theory, and the neoclassical growth theory can be examined within a single theoretical framework.

This book was born out of a five-years research at Sonderforschungsbe reich 303 by the Deutsche Forschungsgemeinschaft (DFG) at Rheinische Friedrich-Wilhelms-Universitiit Bonn and was approved as my doctoral thesis by the Rechts-und Staatswissenschaftliche Fakultiit in December 1994.

Project planning, scheduling, and control are regularly used in business and the service sector of an economy to accomplish outcomes with limited resources under critical time constraints.

However, this way of tackling portfolio problems is not restricted to portfolio problems with default able assets only, but it provides a general framework allowing for a compact formulation of portfolio problems even if interest rates are stochastic.

This book contributes to re cent developments on the statistical analysis of multiple time series in the presence of regime shifts. This study is intended to provide a systematic and operational ap proach to the econometric modelling of dynamic systems subject to shifts in regime, based on the Markov-switching vector autoregressive model.

Economic application of nonlinear dynamics, microscopic agent-based modelling, and the use of artificial intelligence techniques as learning devices of boundedly rational actors are among the most exciting interdisciplinary ventures of economic theory over the past decade.

The book develops the Dempster-Shafer Theory with regard to the reliability of reasoning with uncertain arguments. Of particular interest here is the development of a new synthesis and the integration of logic and probability theory. The reader benefits from a new approach to uncertainty modeling which extends classical probability theory.

The problem of predicting interregional commodity movements and the regional prices of these commodities has intrigued economists, geographers and operations researchers for years.

There are two types of tenn structure models in the literature: the equilibrium models and the no-arbitrage models. Ho and Lee (1986) invent the no-arbitrage approach to the tenn structure modeling in the sense that the model tenn structure can fit the initial (observed) tenn structure of interest rates.

Analysing how corporate finance decisions influence strategic competition and innovation of firms in the product market, this book considers bank loan and venture capital financing and shows that better access to financial resources improves a firm's market position and leads to innovation.

This collection of 188 nonlinear programming test examples is a supplement of the test problem collection published by Hock and Schittkowski [2].

Arguably the central problem in operations research and management science (OR/MS) addressed by e-Business is better coordination of supply and de mand, including price discovery and reduction of transactions costs of buyer seller interactions.

This text develops and analyzes dynamic decision models (DDM) with one trajectoral objective according to the methodology of multi-criteria decision making. DDMs which concomitantly pursue multiple objectives are analyzed, with an emphasis on hybrid models with scalar and trajectorial objectives.

In this book binary functions and their representation by implicants or implicates are described. It is shown that implicants (implicates) of discrete functions may be constructed with the help of implicants (implicates) of binary functions.

Variational inequalities proved to be a very useful and powerful tool for in vestigation and solution of many equilibrium type problems in Economics, Engineering, Operations Research and Mathematical Physics.

The present study has been accepted as a doctoral thesis by the Depart­ ment of Economics of the Johann Wolfgang Goethe-University in Frankfurt am Main. It grew out from my five year long participation in two research projects, "Econometric analysis of transaction intensity and volatility on fi­ nancial markets", and "Microstructure on financial markets", that were both conducted by the chair of Statistics and Econometrics (Empirical Economic Research) at the Department of Economics and Business Administration, Jo­ hann Wolfgang Goethe-University in Frankfurt am Main and financed by the state of Hessen. During this time I have benefitted from many people. First and foremost I would like to thank my thesis supervisor, Prof. Dr. Reinhard Hujer, for initiating and supporting my studies with great encouragement. I am also very grateful to Prof. Dr. Christian Schlag for acting as the second thesis supervisor. Furthermore, I wish to thank Prof. Dr. Joachim Grammig who introduced me to the topics covered in this study in the first place and helped me to sharpen my views on econometrics and financial market microstructure theory through many discussions and also through his willingness to work with me on several related studies.

Network problems are manifold and extremely complex. The text provides a fairly integrated approach of transportation related "network problems" and their "solutions" with emphasis on economics or, more precisely, microeconomic theory.

In the last 25 years, the fuzzy set theory has been applied in many disciplines such as operations research, management science, control theory, artificial intelligence/expert system, etc.

Appropriate parts of my correspondence and some copies of documents will be placed in a Cowles Commission archive at the Cowles Foundation, Vale University.

This study is concerned with forecasting time series variables and the impact of the level of aggregation on the efficiency of the forecasts. The present study contains major extensions of that research and also summarizes the earlier results to the extent they are of interest in the context of this study.

In this book problems related to the choice of models in such diverse fields as regression, covariance structure, time series analysis and multinomial experiments are discussed. The emphasis is on the statistical implications for model assessment when the assessment is done with the same data that generated the model.

This text studies how domestic labour markets are influenced by a changing international environment. It combines developed searches and matching models with standard models of international trade, so the reader can gain insights into the ongoing debate on how globalization can affect unemployment.

The organizers of the 12th International Conference on Multiple Cri teria Decision Making (MCDM) held June 19-23, 1995 in Hagen received the second time the opportunity to prepare an international conference on MCDM in Germany;
