We design an experiment to study the role of (a)symmetry in the context of group lending with joint liability. The performance of joint-liability contracts crucially hinges on borrowers engaging in peer monitoring. We find that asymmetric contracts, in which monitoring is a dominant strategy for...

"We devise an experiment to explore the effect of different degrees of competition on optimal contracts in a hidden-information context. In our benchmark case, each principal is matched with one agent of unknown type. In our second treatment, a principal can select one of three agents, while in...
