Abstract: |
Microfinance groups often engage in a variety of collective activities not
directly related to credit. Groups can sanction members who default on their
loans by excluding them from these activities. Our experiment is designed to
explore the effectiveness of such sanctions in improving repayment incentives.
Groups of 10 members are provided with joint-liability loans for a specific
investment project. If groups repay their loans, contributing members have the
option of excluding other members and those that remain play a public goods
game. By varying loan sizes across groups and allowing for heterogeneous gains
from the public good within groups, we identify the role of incentives in
repayment decisions. In line with theoretical predictions, groups with the
largest repayment burdens have the highest default rates and within groups,
individual decisions to contribute to loan repayment depend on gains from the
public good game. |
