In revising the Tinbergen Lectures I have expanded and restructured the material in an attempt to make the book more readable and more interesting. I have also tried to show more clearly its relevance to managerial and organizational practice. Some mathematical derivations have been moved to appendices. Certain sections that may be skipped in a first reading have been starred. Points that should be of interest to management include • the nature and necessity of rank (4. 1, 4. 2, 4. 4) rank assignment by counting up or down (4. 3) defining an organization's task (6. 2) calculating the required size of an organization (6. 3) • allocating supervisors in the short run (6. 7) when uniform spans of control are desirable (6. 8) • how to estimate an organization's implicit span of control (7) determining the minimal ranks in supervision (8. 3) • the advantage of flexible department lines (8. 4) measuring the leanness of an organization (8. 5) the relationship between average wage and unit labor cost (10. 2) job allocation in the short run (10. 4) • calculating the cost of supervision for particular jobs (10. 5) • recognizing economic choices in substituting managers for operatives or vice versa (11) • determining the optimal size of a research team (12) VI • setting targets (13. 1) • budgeting under full information (13. 2) • budgeting under imperfect information (13. 3) • sources of information loss (14.

Economics of Knowledge explores the theory and empirical facts needed for rational decisions on knowledge investments, creative processes and management of knowledge based industries and institutions. The accumulation of knowledge through higher education, scientific research and industrial R&D is a key factor in economic and social development. This timely and valuable book focuses on the micro- and macroeconomics of knowledge production, and on the analysis of technical constraints, possibilities of collaboration and incentives for scientists, academic teachers and students. The authors move on to analyze the advantages and disadvantages of centrally controlled and competitive university systems, before concluding with a set of decision-making rules for government, university administrations and industry.This book on a hotly contested subject will be widely sought after by those with an interest in economics, management, operations research, regional science and planning as well as consultants to knowledge based industries. R&D managers of industrial firms will learn a great deal from this book as will managers of universities and research institutes.

In dem vorliegenden Buch wird dargestellt, wie Lagerhaltung nach den heutigen Erkenntnissen mit Hilfe von Operations Research rational gestaltet werden kann. Es werden neben deterministischen Lagerhaltungsmodellen (Produktionslager) auch Modelle mit stochastischer Nachfrage (Handelslager) bei kontinuierlicher und periodischer Inspektion behandelt. Das von den beiden praxiserfahrenen Verfassern geschriebene Lehrbuch befaßt sich neben dem operationalen Aspekt der Losgrößenoptimierung auch mit Fragestellungen auf höherer Managementebene (Lager in Lizenz, Wert des Bestandes, Budget- oder Raumknappheit). Es ist das Ziel, interessierte Studenten, Systementwickler und Unternehmensberater mit dem Basiswissen vertraut zu machen und sie zu befähigen, einen gegebenen Fall mit Hilfe der erlernten Methoden eigenständig zu bearbeiten. Zu diesem Zweck werden die verwendeten Techniken an den verschiedenen Modellen ausführlich vorgeführt. Alle benötigten mathematischen Ableitungen werden vollständig und verständlich beschrieben. In einem eigenen Kapitel wird eine Einführung in die für die stochastische Lagerhaltung wichtigen Rechenverfahren der dynamischen Optimierung gegeben.

If production exhausts some resources and these are necessary in future production even though some substitution of producible resources is pos- sible, how should the available stocks of exhaustible resources be allocated to present and future production? The objective considered is to maximize the present value of the utility of current and future consumption. When production functions are Cobb-Douglas and the utility functions are logarithmic, the optimum decision rule has the simple form: use up the fraction l-e of the remaining amount of every exhaustible resource in every period. Here fl is the discount factor. Conversely if rates of use of exhaustible resources are given, then these imply a time rate of discount for future utility. Depending on e and on the rate of technical progress (assumed as exogeneous) a stationary state or even growth are possible. But rates of resource exhaustion above a critical level imply a steady decline and eventual extinction. La production epuisant certaines resources qui seraient indispensables a la production future bien qu'on puisse substituer a un certain degre, les resources productibles, comment faut-il assigner a la production presente et future, les stocks disponibles des resources epuisables? II faut resoudre ce probleme dans Ie but de porter au maximum, la valeur actuelle de l'utilite de la consommation courante et future.
