We study endogenous group formation in tournaments employing experimental three-player contests. We find that players in endogenously formed alliances cope better with the moral hazard problem in groups than players who are forced into an alliance. Also, players who are committed to expending...

We study the role of an imbalance in fighting strengths when players bargain in the shadow of conflict. Our experimental results suggest: In a simple bargaining game with an exogenous mediation proposal, the likelihood of conflict is independent of the balance of power. If bargaining involves...

Fiscal rules specify quantitative targets for key budgetary aggregates. In this paper, we review the experience with such rules in Japan and in the EU. Comparing the performance of fiscal policy in the 1980s and 1990s until 2003, we find that the fiscal rule of the 1980s exerted some but not...

We discuss two essential problems of the political economy of public finances: The principal agent problem between voters and elected politicians and the common pool problem arising from the fact that money drawn from a general tax fund is used to pay for policies targeting more or less narrow...

This paper uses a new data set on budgetary institutions in Europe to examine the impact of fiscal rules and budget procedures in EU countries on public finances. It briefly describes the main pattern of budgetary institutions and their determinants across the EU 15 member states. Empirical...

Law makers increasingly try to capitalize on individuals having acquired knowledge of corporate crimes or other misconduct by inducing them to blow the whistle. In a laboratory experiment we measure the effectiveness of incentives on the willingness to report such misconduct to a sanctioning...

Crime has to be punished, but does punishment reduce crime? We conduct a neutrally framed laboratory experiment to test the deterrence hypothesis, namely that crime is weakly decreasing in deterrent incentives, i.e. severity and probability of punishment. In our experiment, subjects can steal...
