Collusion and Group Lending with Adverse Selection


  • Laffont, Jean-Jacques


In an environment with correlated returns, this paper characterizes optimal lending contracts when the bank faces adverse selection and borrowers have limited liability. Group lending contracts are shown to be dominated by revelation mech- anisms which do not use the ex post observability of the partners\' performances. However, when collusion between borrowers under complete information is allowed, group lending contracts are optimal in the class of simple revelation mechanisms (which elicit only the borrower\'s own private information) and remain useful with extended revelation mechanisms.
