Institutions that rely on joint liability to facilitate lending to the poor
have a long history and are now a common feature of many developing countr
ies. Economists have proposed several theories of joint-liability lending t
hat stress various aspects of its informational and enforcement advantages
over other forms of lending. This paper analyzes how joint-liability lendin
g promotes screening, monitoring, state verification and enforcement of rep
ayment. An empirical section draws on case studies to highlight how joint l
iability works in practice. (C) 1999 Elsevier Science B.V. All rights reser
