In many rural settings, informal mutual support networks have evolved into semiformal insurance groups, such as funeral societies.  Using detailed panel data for six villages in Ethiopia, we can distinguish two types of contracts, in terms of whether payments are only made at the time of death...

The existing literature on sub-game perfect risk-sharing suffers from a basic inconsistency. While a group of size "n" is able to coordinate on a risk-sharing outcome, it is assumed that deviating subgroups cannot. I relax this assumption and characterise the optimal contract among all...

This paper models the implications of endogenous group formation for efficient risk-sharing contracts in the dynamic limited commitment model.  Endogenising group formation requires that any risk-sharing arrangement is not only stable with respect to individual deviations but also with respect...

Over the past decade, Kenya's traditional model of local, community finance and management of schools has been crowded out from two directions. First, the Kenyan government has expanded its role in public education, through free provision of primary and, more recently, secondary education....

The recent political economy literature on institutions for growth views low and ineffective spending on service delivery sectors as a symptom of the underlying institutional environment. But if institutions are the outcome of decisions by policymakers and serve the purpose of benefitting some...

This study was prepared for the Financial Services and Poverty Reduction research project and was presented at the conference with the same name held at Bank headquarters in September of 2004. It first establishes the considerable welfare cost borne by the region's poor when facing uncovered...

We model the emergence of formal insurance institutions as equilibria under limited contract enforceability where groups are required to be coalition-proof but also can use fines for enforcement. The model can generate coexistence of formal and informal groups without requiring heterogeneity in...

In 2003 Kenya abolished user fees in all government primary schools. Analysis of household survey data shows this policy contributed to a shift in demand away from free schools, where net enrollment stagnated after 2003, toward fee-charging private schools, where both enrollment and fee levels...
