This paper experimentally investigates whether agents behave differently if their own earnings are at stake (effort experiment) or a budget that is provided to them like a sort of manna from heaven (no-effort experiment) . We use the so-called power-to-take game, employed by Bosman & Van Winden...

Credence goods markets are characterized by asymmetric information between sellers and consumers that may give rise to inefficiencies, such as under- and overtreatment or market break-down. We study in a large experiment with 936 participants the determinants for efficiency in credence goods...

We study the effects of communication in an experimental tournament between teams. When teams, rather than individuals, compete for a prize there is a need for intra-team coordination in order to win the inter-team competition. Introducing communication in such situations may have ambiguous...

We study behavior in a search experiment where sellers receive randomized bids from a computer. At any time, sellers can accept the highest standing bid or ask for another bid at positive costs. We find that sellers stop searching earlier than theoretically optimal. Inducing a mild form of time...

In an overlapping generations experiment with multiple families participants can support their parents directly and thereby reduce their tax burden or rely on tax-financed old-age support. State productivity is captured by the factor with which total tax revenues are multiplied to determine...

In an experiment, we study risk-taking of cohabitating student couples, finding that couples’ decisions are closer to risk-neutrality than single partners’ decisions. This finding is similar to earlier experiments with randomly assigned groups, corroborating external validity of earlier results.

Many tournaments are plagued by sabotage among competitors. Typically, sabotage is welfare-reducing, but from an individual's perspective an attractive alternative to exerting positive effort. Yet, given its illegal and often immoral nature, sabotage is typically hidden, making it difficult to...
