Public goods provision often involves groups of contributors repeatedly interacting with administrators who can extract rents from the pool of contributions. We suggest a novel identification approach that exploits the sequential ordering of decisions in a panel vector autoregressive model to...

This paper considers the classical independent private values model of auction theory in the presence of income taxation. We show that revenue equivalence remains valid if income taxes are proportional. Progressive and regressive taxes lead, in general, to asymmetries between bidders with the...

Vendettas occur in many real-world settings where rivals compete for a prize, e.g., winning a competitive promotion or retaining a job, by engaging in aggressive, retaliatory behavior. We present a benchmark experiment where two players have an initial probability of winning a prize. Retaliatory...

Social insurance such as unemployment insurance is in many countries mandatory for the majority of workers. The extent of such insurance is determined by a political process, i.e. ultimately by the workers themselves. If unemployment were purely accidental then all risk averse workers should...

We study experimentally how players learn to make decisions if they face many different (normal-form) games. Games are generated randomly from a uniform distribution in each of 100 rounds. We find that agents do extrapolate between games but learn to play strategically equivalent games in the...
