WHATEVER HAPPENED TO THE PHILOSOPHER-KING? THE LEADER'S ADDICTION TO POWER

This articles postulates the existence of a number of conscious and unconscious forces which make leaders reluctant to relinquish power. It is suggested that a major reason for the unwillingness to let go is the transferential effects of leadership. Both mirroring and idealizing transference reactions are discussed. In addition, there is the ageing factor which may contribute to the addictiveness of power, since ageing can evoke a strong need for compensatory strivings. the talionic principle - meaning in this case the conscious or unconscious fear that the loss of power will be followed by some form of retaliation for previous acts - may be another factor contributing to power's addictiveness. In this context the role of envy is emphasized. Finally, the existence of a ‘fear of nothingness’ is postulated, that is, a form of anxiety which leads to a need to defeat death by leaving some kind of legacy. It is suggested that holding onto power is linked to the fear that this legacy may be destroyed.     

Precommitment by central bank independence

The paper addresses the issue of central bank independence. The central argument is that government can precommit to the objective of price stability by providing a constitutional status of independence to the central bank. A sufficient set of institutional elements and the problem of incentive compatibility are discussed. It is argued that the solution is superior to a constitutional money rule as no rule can take adequately into account trend changes in output or velocity.     

Efficient organization of information processing

The paper examines the application of the concept of economic efficiency to organizational issues of collective information processing in decision making. Information processing is modeled in the framework of the dynamic parallel processing model of associative computation with an endogenous setup cost of the processors. The model is extended to include the specific features of collective information processing in the team of decision makers which may lead to an error in data analysis. In such a model, the conditions for efficient organization of information processing are defined and the architecture of the efficient structures is considered. We show that specific features of collective decision making procedures require a broader framework for judging organizational efficiency than has traditionally been adopted. In particular, and contrary to the results available in economic literature, we show that there is no unique architecture for efficient information processing structures, but a number of various efficient forms. The results indicate that technological progress resulting in faster data processing (ceteris paribus) will lead to more regular information processing structures. However, if the relative cost of the delay in data analysis increases significantly, less regular structures could be efficient. Copyright © 2007 John Wiley & Sons, Ltd.     

The Kreps-Wilson monopoly-entrant game and cautiously rationalizable sequential equilibria

In this paper the α and β characteristic functions are reviewed and a new concept, the credible threat function, is introduced following some tentative remarks on the credibility of threats.     

R&D activity in a dynamic factor demand model

The focus of this paper is an econometric analysis of the determinants of private firms' R&D activities in the context of a general dynamic factor demand model. Besides the traditional production factors we treat technological knowledge, endogenously determined by R&D expenditures, as a further input factor. While labour and materials are assumed to be variable, capital and know-how are considered as quasi-fixed. The dynamic demand equations for labour, capital investment and R&D which are derived from an intertemporal cost minimisation are estimated for a panel data set of small and medium size German firms. The data covers the period between 1978 and 1982 and includes 408 firms. It turns out that R&D activity depends on the underlying production structure as suggested by neoclassical theory. In addition, by introducing firm specific effects, we can show that firm size and market concentration influence innovative behaviour in accordance with the Schumpeterian hypotheses.Paper presented at the Industrial Organization Conference at the Annual Meeting of the Austrian Economic Association, Vienna, June 24–26, 1992, the 7th Annual Congress of the European Economic Association, Dublin, August 29–31, 1992, and the 19th Annual Conference of the EARIE, Stuttgart, September 4–6, 1992. Helpful suggestions and comments were received from participants of these conferences as well as from seminar participants at Temple University, at the University of Augsburg, and at the fourth DFG workshop Marktstruktur und gesamtwirtschaftliche Entwicklung in Munich. We are particularly indebted to an anonymous referee for very helpful specific comments. Finally, we would like to thank Horst Albach for providing us with the panel data set. Financial support of the DFG is gratefully acknowledged.     

The effects of tied and untied development loans

A decisive change now seems to be occurring in the development practices of the major OECD donor countries. Their own economic objectives are being moved distinctly closer to centre stage. Changes in the instruments of development policy are reputed to generate direct benefits for their own economies. The following article shows that such behaviour is questionable.
