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 propose a simple adaptive learning model to study behavior in the call market. The laboratory environment features buyers and sellers who receive a new random value or cost in each period, so they must learn a strategy that maps these random draws into bids or asks. We focus on buyers'...

We study the role of an imbalance in fighting strengths when players bargain in the shadow of conflict. Our experimental results suggest: In a simple bargaining game with an exogenous mediation proposal, the likelihood of conflict is independent of the balance of power. If bargaining involves...
