We experimentally explore indefinitely repeated contests. Theory predicts more cooperation, in the form of lower expenditures, in indefinitely repeated contests with a longer expected time horizon, and our data support this prediction, although this result attenuates with contest experience....

This paper proposes the Stochastic-Share Contest, a novel contest format that combines the Winner-Take-All Contest and the Proportional-Prize Contest, with the former nesting the latter two as special cases. Motivated by the experimental contest literature, we include risk aversion and a "joy of...

We use a laboratory experiment to study the effects of disclosing the number of active participants in contests with endogenous entry. At the first stage potential participants decide whether to enter competition, and at the second stage entrants choose their investments. In a 2×2 design, we...

Incentive schemes that reward participants based on their relative performance are often thought to be particularly risk-inducing. Using a novel, real-effort task experiment in the laboratory, we find that the relationship between incentives and risk-taking is more nuanced and depends critically...

We study experimentally the effects of sorting in contests between groups of heterogeneous players whose within-group efforts are perfect substitutes. The theory predicts that higher aggregate effort will be reached when variation in ability between groups is lower, i.e., by a more balanced...

Contests between groups of workers are often used to create incentives in organizations. Managers can sort workers into groups in various ways in order to maximize total output. We explore how the optimal sorting of workers by ability in such environments depends on the degree of effort...

Overconfidence in one's relative performance within a group is a wide-spread phenomenon. Similar to individual (or within-group) overconfidence, it was also shown that individuals are, on average, overconfident about the performance of their group relative to other groups. We hypothesize that...
