Are 18 Holes Enough for Tiger Woods?

This article addresses the selection problem in promotion tournaments. I consider a situation with heterogeneous employees and ask whether an employer might be interested in repeating a promotion tournament. On the one hand, this yields a reduction in uncertainty over the employees’ abilities. On the other hand, there are costs if a workplace stays vacant.     

Cumulative prospect theory and the St. Petersburg paradox

Summary. We find that in cumulative prospect theory (CPT) with a concave value function in gains, a lottery with finite expected value may have infinite subjective value. This problem does not occur in expected utility theory. The paradox occurs in particular in the setting and the parameter regime studied by Tversky and Kahneman [15] and in subsequent works. We characterize situations in CPT where the problem can be resolved. In particular, we define a class of admissible probability distributions and admissible parameter regimes for the weighting- and value functions for which finiteness of the subjective value can be proved. Alternatively, we suggest a new weighting function for CPT which guarantees finite subjective value for all lotteries with finite expected value, independent of the choice of the value function. Some of these results have already been found independently by Blavatskyy [4] in the context of discrete lotteries.Received: 14 October 2004, Revised: 6 May 2005, JEL Classification Numbers: C91, D81.We thank Pavlo Blavatskyy and Thorsten Hens for their helpful remarks regarding our paper.

Monoculture versus diversity in competition economics

Economics rightfully represents the major basis for competitionpolicy. Next to generating knowledge about competition and itswelfare effects, the currently popular ‘more-economicapproach’ is charged with a number of additional hopesand expectations. While this article highlights the benefitsof economics-based competition policy, it takes a cautious stancetowards excessive expectations, in particular regarding theidea that a monocultural, ‘unified’ competitiontheory as an exact, objective and unerring scientific approachto antitrust could make normative assessment and generalisationssuperfluous. Diversity in competition economics is advocatedin two ways. First, competition economics is empirically characterisedby a considerable pluralism of theories and policy paradigms.Second, it is demonstrated that this diversity of theories istheoretically beneficial for future scientific progress. Asno ultimate competition theory can ever be expected., the ‘more-economicapproach’ must be extended in order to embrace diversity.     

Domestic Distortions and the Early Emergence of the International Trade in Fire Insurance from the UK

In the second half of the nineteenth century, British fire insurance exports grew rapidly to more than half of the revenue accepted by British fire insurance companies. It has been suggested by some, including Michael Porter, that this expansion was based on a comparative advantage created in large part by a highly competitive domestic insurance market. Yet the existence of strong and sophisticated cartels in the British insurance market is well known. The paper argues that in fact the chief motive for the drive to develop business abroad came from the existence of the cartel, whose increasing power prompted the creation of a number of new well‐supported companies. The circumstances of the insurance business forced them to develop a large and diversified business and this required them to join the cartel. This membership deprived them of the price weapon to develop their business in the domestic market. They were thus forced to develop innovative strategies to grow. One of these was to deploy innovative marketing policies at home. The other was to expand abroad. By contrast, most of the older companies that had created the cartel developed foreign business later and on a far smaller scale.     

The brain drain: A tax analysis of the Bhagwati proposal

To alleviate the problems caused by the brain drain, Professor Bhagwati proposes that professional, technical, and kindred persons who emigrate from less developed countries be subjected to a special tax on the income they earn in developed countries. This paper highlights the political and legal issues raised by his proposal and examines three approaches to implementation: a tax levied by the less developed country, a tax levied by the developed country, and a tax levied by the United Nations. Specific aspects of the proposal which require further study and refinement, such as administrative feasibility, are outlined.
