From a game theoretic point of view, fraudulent accounting to em-bellishnthe financial status of a firm and the use of drugs to enhancenperformance in sports are very similar. We study the replicator dy-namicsnof both applications within the same model. We allow for het-erogenousnpopulations, such as highly talented versus more mediocrenathletes, or high quality managers versus less…

Nowdays many nations can review proposed mergers and US law firms help clients overcome such regulatory hurdles, effectively greasing the market for corporate control. However, they can also oppose…

Based on an experimental analysis of a simple monetary economy we argue that a monetarynsystem is more stable than one would expect from individual rationality. We show thatnpositive reciprocity stabilizes the monetary system, provided every participant considers thenfeedbacks of his choice to the stationary equilibrium. If however the participants do not playnstationary strategies…

Multistage stochastic programs with continuous underlying distributions involve the obstacle of high-dimensional integrals where the integrands' values again are given by solutions of stochastic programs. A common solution technique consists of discretizing the support of the original distributions leading to scenario trees and corresponding LPs which are ? up to a certain size…

Little is known on the existence of negative relative demand shocks against low-skilled workers on a ‘US-style' deregulated labour market with a ‘German-style' vocational (apprenticeship) education system. Switzerland provides an appealing testing ground to investigate this question. Traditionally a ‘zero unemployment' economy, Switzerland has seen an unprecedented…

This paper shows that a stock market is evolutionary stable if andnonly if stocks are evaluated by expected relative dividends. Any othernmarket can be invaded by portfolio rules that will gain market wealthnand hence change the valuation. In the model the valuation of assetsnis given by the wealth average of the portfolio rules in the market. Thenwealth dynamics is modelled as a…

Terrorism will be high on the political agenda for many years to come. Various policies are open to a government fighting terrorism but, in any case, considerable costs are involved. In the competition for politicalnsupport, the costs and benefits of anti-terrorism policies will be debated. Better information about terrorism and its consequences can improve policy outcome if there is…

This paper reports on a re-evaluation of the German health care reform of 1997. A previous evaluation found a limited effect of a 4.4 percent reduction of the number of doctor visits in a sample of pharmacy customers. The re-evaluation based on a representative household survey, the German Socio-Economic Panel, yields a much larger effect. The paper uses this case study to discuss…
