Doping tests create a signal of whether the athlete has acted fraudulently. If the signal is costly, but perfect, then the doping enforcer and the athlete play an “inspection game," which has no equilibrium in pure strategies. This paper presents a modification of that game: The “Bayesian...

Virtual communities like Second Life represent an economic factor with increasing potential, but may induce behavior that deviates from real world experience. We introduce a new experimental design that is based on the trust game (Berg, Dickhaut, and McCabe 1995), but eliminates the problem of...

Would the introduction of a corporate tax system with consolidated tax base and formula apportionment lead to socially wasteful mergers and acquisitions across borders? This paper analyzes a two-country model with an international investor considering acquisitions of already existing target...

Spezialisierte Stroke Units bieten Schlaganfallpatienten die bestmögliche Behandlung – ihrer flächendeckenden Einrichtung steht allerdings akuter Mangel an erfahrenen Neurologen sowie die geringe Schlaganfallinzidenz in dünnbesiedelten, ländlichen Gebieten entgegen. Hier werden zunehmend...

Modeling and estimating the loss given default (LGD) is necessary for banks which apply for the Internal-Ratings Based Approach for retail portfolios. To validate LGD estimations there are only very few approaches discussed in the literature. In this paper, two models for validating relative...

The fascination of venture creation is associated with an entrepreneur’s opportunity of achieving personal fulfillment. In reality, however, many nascent entrepreneurs discover that much of their original vision is sacrificed in the process of creating a startup. In this paper we address the...

This study focuses on the question whether it is risk aversion or the beliefs of players that explains the strategic choices in 2x2 coordination games. In a laboratory experiment, we elicit the risk attitudes by using lottery choices. Furthermore, using a quadratic scoring rule, subjects’...

In manual order picking systems, order pickers walk or ride through a distribution warehouse in order to collect items requested by (internal or external) customers. In order to perform these operations efficiently, it is usually required that customer orders are combined into (more substantial)...

This paper analyzes the impact of shortening the duration of secondary schooling on the accumulation of human capital. In 2003, an educational policy reform was enacted in Saxony-Anhalt, a German state, providing a natural experimental setting. The thirteenth year of schooling was eliminated for...

The aim of our paper is the development of an adequate estimation model for the loss given default, which incorporates the empirically observed bimodality and bounded nature of the distribution. Therefore we introduce an adjusted Expectation Maximization algorithm to estimate the parameters of a...
