This paper studies the evolution of self-enforcing reciprocity norms in a developing economy with weak property rights. In the model, children are viewed as investments in old-age support. In order to increase support in their old age, parents attempt to instill preferences for reciprocity in...

This note reconsiders a theoretical result asserted to explain the success of group lending programs in LDCs. It has been claimed that if groups are allowed to form themselves, risky and safe borrowers will sort themselves into relatively homogenous groups. This "positive assortative matching"...

This paper surveys the theoretical and empirical literature on group lending programs in developing countries, with a focus on the determinants of repayment performance.

This paper revisits the conventional wisdom on the determinants of the success of microcredit programs. The paper first develops a simple moral hazard model of borrowing in a group lending context, and then tests this model using data from a survey conducted in Bangladesh in 1991-92. One of the...

This paper develops a model of the strategic interaction of borrowers in the framework of group lending, in an environment characterized by moral hazard. Unlike previous papers, monitoring by one group member of his or her peers is not a crucial feature of the model. Even without monitoring,...

This paper contributes to the literature on endogenous preferences by showing that, when income is close to the minimum required for subsistence, individuals rationally will behave as if they were risk averse. It is suggested that observed risk aversion in empirical studies can be explained by...

A long series of laboratory and field experiments, as well as conventional empirical studies, has established that (1) individuals voluntarily provide themselves with public goods at levels exceeding those predicted by the Nash voluntary contributions mechanism, and (2) agents reciprocate...
