Group-lending: Sequential financing, lender monitoring and joint liability

We develop a simple model of group-lendingbased on peer monitoring and moral hazard. We find that, in the absence of sequential financing or lender monitoring, group-lending schemes may involve under-monitoring with the borrowers investing in undesirable projects. Moreover, under certain parameter configurations, group-lending schemes involving either sequential financing, or a combination of lender monitoringand joint liability are feasible. In fact, group-lending schemes with sequential financing may succeed even in the absence of joint liability, though the repayment rate will be lower. In the absence of joint liability, however, group-lending with lender monitoring is unlikely to be feasible.
