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 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...

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...
