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 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...

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 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...

Individuals belonging to a social group make judgments about their relative standing within the group as well as about the relative standing of their group among other groups. On average, individuals exhibit overconfidence bias in both types of judgments in a variety of settings. We hypothesize,...

Many empirical studies have found a positive association between economic development and democracy survival across countries; however, establishing a causal link between the two with naturally occurring data is problematic. We address this question in a laboratory experiment with democracy...

We model corruption in a society as a result of bargaining for bribes between private citizens and public officials. We investigate the role that incomplete information with respect to the intrinsic moral cost of one's potential corruption partner plays out in his or her propensity to engage in...

The unskilled-and-unaware problem describes a negative relationship between one’s skill level and self-assessment bias: the less skilled are, on average, more unaware of the absolute and relative quality of their performance. In this paper, we study whether, and to what extent, the...
