Ziel dieser Arbeit ist es, in die ökonomische Analyse des Versicherungsbetrugs einzuführenund einige grundlegende Determinanten für vertragswidriges Verhalten von Versicherungsnehmern aufzuzeigen. Dazu werden zunächst die strategischen Entscheidungsprobleme von Versicherungsneh-mern und...

We study the role of whistleblowing in the following inspection game. Two agents who compete for a prize can either behave legally or illegally. After the competition, a controller investigates the agents' behavior. This inspection game has a unique Bayesian equilibrium in mixed strategies. We...

This paper looks at the current shadow-banking practices of Chinese SME's and the question if these practices have a positive impact on the development of those SME's. For this pur-pose, new primary data is examined: Four case studies and two supplementary sets of data. Although the data volume...

We analyze the costs and benefits of using social image to foster virtuous behavior. A Principal seeks to motivate reputation-conscious agents to supply a public good. Each agent chooses how much to contribute based on his own mix of public-spiritedness, private signal about the value of the...

Policies targeted at high-crime neighbourhoods may have unintended consequences in the presence of organised crime. Whilst they reduce the incentive to commit crime at the margin, those who still choose to join the criminal organisation are hardened criminals. Large organisations take advantage...

We study an individual's incentive to search for a job in the presence of random criminal opportunities. These opportunities extenuate moral hazard, as the individual sometimes commits crime rather than searching. Even when he searches, he applies less effort. We then revisit the design of...

A simple decision theoretic model shows the doping incentives for a member of a professional sports team. Depending on the detection probability and the punishment, a sportsman dopes not at all, at a medium or at the maximal level. The whole team has a higher incentive than an individual team...

We characterize equilibria of an income reporting game with bounded returns and no commitment where detected tax evaders are charged the maximally feasible amount. Introducing partial commitment to punishment relief eliminates multiplicity of equilibria. We identify a unique limit equilibrium...

Two firms produce a product with a horizontal and a vertical characteristic. We call the vertical characteristic quality. The difference in the quality levels determines how the firms share the market. Firms know the quality levels, consumers do not. Under non-comparative advertising a firm may...

An arbiter can decide a case on the basis of his priors, or the two parties to the conflict may present further evidence. The parties may misrepresent evidence in their favor at a cost. At equilibrium the two parties never testify together. When the evidence is much in favor of one party, this...
