This is the fourth version of a model that five years ago we set out to build and estimate along the lines of the continuous time approach clarified In chapter 1. Previous versions appeared in journal articles and conference proceedings, where the space is notoriously limited. Therefore we welcome the possibility of publishing a book-length treatment of this fourth version, so that we can describe its theoretical and empirical aspects in some detail. Although we have worked closely together and accept joint responsibility for the whole book, chs. 1 and 2 and appendix I have been written by G....

This volume collects papers prepared for the workshop '~isspecification Ana- lysis" held in Groningen. The Netherlands. December 15th and 16th. 1983. The papers. which cover a wide range of problems. contain a number of interesting and fruitful ideas. A bird's-eye view of the contents of the papers is as follows: White describes in a very general setting properties of classical statistical procedures when models are misspecified. Verbeek provides a lucid analysis of the statistical complexity of the model selection process. Dijkstra indicates how to construct good estimators. taking the...

The Sixth International Multiple-Criteria Decision Making (MCDM) Conference is one of a biennial series that serve as a forum for exchange of the latest information and new developments in this rapidly growing field. Participants are carefully chosen from among scholars and practitioners so that widely ranging perspectives and disciplines are represented; this insures the dissemination of valuable new know ledge to those scholars, policy-makers and industrial analysts who will best utilize and share it, both in developed and in third-world countries. The Sixth Internaitona1 MCDM Conference...

A few years ago nobody would have anticipated that in connection with degeneracy in Linear Programming quite a new field. could originate. In 1976 a very simple question has been posed: in the case an extreme pOint (EP) of a polytope is degenerate and the task is to find all neighbouring EP's of the degenerate EP, is it necessary to determine all basic solutions of the corresponding equalities system associated with the degenerate EP -in order to be certain to determine all neighbours of this EP? This question implied another one: Does there exists a subset of the mentioned set of basic...

The airframe industry is usually recognized as being different from most manufacturing industries. These differences, which are characterized by the number of units produced and the frequency of design changes, have been evident for many years. This uniqueness and the corresponding implications for cost estimation became particularly evident during World War II. The aircraft industry generally has been considered unique in that it differs from other manufacturing in the quantity of units manufactured and with the frequency with which changes are made during the course of manufacturing...

The distribution of capital and income in general and its re lation to wealth and economic growth in particular have attrac ted economists' interest for a long time already. Especially the, at least partially, conflicting nature of the two politi cal objectives, namely to obtain substantially large economic growth and a "just" income distribution at the same time, has caused the topic to become a subject of political discussions. As a result of these discussions, numerous models of workers' participation in the profits of growing economies have been developed. To a minor extent and with quite...

During the week of October 24-28, 1983, a group of mathematicians and eco nomists met at the Institute for Mathematics and it Applications at the University of Minnesota. The workshop dealt with economic models in which time plays an essential role, and both the description of adjustment to a static equilibrium and the description of equilibrium paths were considered. From a mathematical point of view, discrete dynamical systems and the dynamics of ordi nary and partial differential equations played a major role. The conference consisted of lectures by economists and by mathematicians which...

This paper treats a two-echelon inventory system. The higher echelon is a single location reffered to as the depot, which places orders for supply of a single com modity. The lower echelon consists of several points, called the retailers, which are supplied by shipments from the depot, and at which random demands for the item occur. Stocks are reviewed and decisions are made periodically. Orders and/or shipments may each require a fixed lead time before reaching their respective desti nations. Section II gives a short literature review of distribution research. Section III introduces the...
