This monograph is a treatise on adjustment processes. We consider price adjustment processes in exchange economies and strategy adjustment processes in noncooperative games. In the most simple version of an exchange economy, i.e. a pure exchange economy, there exist markets on which prices are determined by the demand and supply created by a finite number of consumers willing to exchange their initial endowments in order to maximize their utilities. An equilibrium situation is attained if, for some price vector, demand equals supply in all markets. Starting from a situation not being an equi...

Generalizations of the classical concept of a convex function have been proposed in various fields. In addition to listing new results in more established areas of generalized convexity theory, this study presents developments in emerging fields and a number of applications.

Jay Forrester's Economic Dynamics was published in 1971 and The Limits to Growth by Dennis Meadows and his associates appeared a year later. The publication of those two books gave rise to twenty years of intense research into the economics of exhaustible resources, research which everywhere has had a substantial impact both on public debate and on academic curricula. And now, just as that line of research is losing steam, economists are focussing on problems associated with the degradation of the natural environment, problems which call for models which, in their formal structure, are quite...

1. 1 Integrating results The empirical study of macroeconomic time series is interesting. It is also difficult and not immediately rewarding. Many statistical and economic issues are involved. The main problems is that these issues are so interrelated that it does not seem sensible to address them one at a time. As soon as one sets about the making of a model of macroeconomic time series one has to choose which problems one will try to tackle oneself and which problems one will leave unresolved or to be solved by others. From a theoretic point of view it can be fruitful to concentrate oneself...

This book deals with lotsizing and scheduling and shows how to determine the size and sequence of lots for a production facility at minimal costs with respect on demand and capacity constraints. Lotsizing is of growing importance in research, teaching, and practice. The discussion of existing models which are proposed in literature results in new types of models for lotsizing and (semi-) scheduling. The models take respect on setup times, sequence dependent setup costs, multi-machines, and make-or-buy decisions in a single- or multi-stage environment.

This book is the result of a four years' research project at the European Uni- versity Institute in Florence, Italy. I am grateful to my supervisor, Mark Salmon, for his many ideas. I am also indebted to my co-supervisor, Aart de Zeeuw, for his and Alister Ulph. unfailing support and to Carlo Carraro, Louis Phlips I gratefully acknowledge the help and assistance of many people that advised at some stage, Scott Barrett, Peter Bohm, Lans Bovenberg, Partha Dasgupta, me Klaus Hasselman, Peter Kort, alIi Tahvonen, Cees Withagen and Clifford Wymer. Thanks also to the faculty and students of the...

Die vorliegende Arbeit behandelt ein aktuelles Thema der Entschei dungstheorie: die Frage nach der optimalen Entscheidung bei mehr facher Zielsetzung. Mit mehrfachen Zielsetzungen setzte sich zu erst die Entscheidungstheorie bei Unsicherheit auseinander. Ge winnerzielung und Risikominderung sind die beiden Ziele eines Akteurs, der eine Entscheidung bei Unsicherheit zu treffen hat. Die Entscheidungstheorie ging bei der Lasung dieses Problems zu nachst von der Existenz einer Risikopraferenzfunktion aus. Spater wurden Zweifel an der Operationalitat dieses Konzepts und seiner axiomatischen...

I was originally induced to think about barriers to entry by some re search done for Charles River Associates, Inc., Boston, on behalf of their client IBM Corporation, Armonk, N.Y. After the end of this re search project I continued to work on entry barriers and related is sues of market structure. The results of this effort are reported here. What I present is not a book in the traditional sense of the word. Due to other research and administrative obligations I could not, without substantial delay, present a more finished product. The rapid progress in the field of industrial organisation...

This study is the result of an interest in the economic theory of production intermittently pursued during the past three years. Over this period I have received substantial support from the Office of Naval Research, first from a personal service consulting contract directly with the Mathematics Division of the Office of Naval Research and secondly from Project N6 onr-27009 at Princeton Univer sity under the direction of Professor Oskar Morgenstern. Grateful acknowledgement is made to the .Office of Naval Research for this support and to Professor Morgenstern, in particular, for his interest...

This mono graph is intended for an advanced undergraduate or graduate course as weIl as for the researchers who want a compilation of developments in this rapidly growing field of operations research. This is a sequel to our previous work entitled "Multiple Objective Decision Making--Methods and Applications: A State-of-the-Art Survey," (No. 164 of the Lecture Notes). The literature on methods and applications of Multiple Attribute Decision Making (MADM) has been reviewed and classified systematically. This study provides readers with a capsule look into the existing methods, their char...
