We introduce intention-based social preferences into a mechanism design framework with independent private values and quasilinear payoffs. For the case where the designer has no information about the intensity of social preferences, we provide conditions under which mechanisms which have been...

We modify the provision point mechanism by introducing reward money, which is distributed among the contributors in proportion to their contributions only when the provision point is not reached. In equilibrium, the provision point is always reached as competition for reward money and preference...

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....

Decision makers lacking crucial specialist know-how often consult with better informed but biased experts. In our model the decision maker’s choice problem is binary and her preferred option depends on the state of the world unknown to her. The expert observes the state and sends a report to...

Szidarovszky and Okuguchi (Games and Economic Behavior, 1997) have provided useful conditions for the existence of a unique purestrategy Nash equilibrium in rent-seeking games of complete information. In this paper, we generalize their results to contests with incomplete information. Two...

We study finitely repeated 2 / 2 normal form games, where players have incomplete information about their opponents’ payoffs. In a laboratory experiment we investigate whether players (a) learn the game they are playing, (b) learn to predict the behavior of their opponent, and (c) learn to...

One of the most basic questions in economics concerns the effects of competition on market prices. We show that the neglect of both fairness concerns and decision errors prevents a satisfactory understanding of how competition affects prices. We conducted experiments which demonstrate that the...

It has often been pointed out in the literature that a symbiotic relationship exists between terrorist groups and the media. As yet, however, no formal model has been built based on this issue and only very little empirical research has been done in this field. The present contribution builds a...

There are at least two reasons why multiple prizes can be optimal in symmetric imperfectly discriminating contests. First, the introduction of multiple prizes reduces the standard deviation of contestants’ effort in asymmetric equilibria, when the majority of contestants actively participate...

Prior research demonstrates a willingness to incur costs to punish norm violators. But, how strong are the motives underlying such acts? Will people rely on "excuses" to avoid acting on costly punishment intentions, as with other costly pro-social acts? In a laboratory experiment, we find that...
