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...

We prove the existence of monotone pure strategy Bayesian equilibria in two types of contests between groups under incomplete information: (i) individual-level private information group contests, where each player only knows her own ability, and (ii) group-level private information group...

We prove the existence of monotone pure strategy Bayesian equilibria in group contests under individual-level and group-level private information. For the latter type, we develop a novel approach reducing group contests to contests between individuals with multi-dimensional types, with...

Contests are meant to attract the best performers and incentivize high effort, however, they may also attract cheaters who try to win via illicit means which crowds out the best performers. We use a laboratory experiment to explore the role of self-selection in contests with a possibility of...

A debate among practicing managers is whether to use cooperative or competitive incentives for team production. While competitive incentives may drive individual effort higher, they may also lead to less help and more sabotage; an issue exacerbated when team members' abilities are varied. Using a...
