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...

Most risk-sharing tests on developing country data are conducted at the level of the village; generally, the full risk-sharing hypothesis is rejected. This paper uses detailed data on all insurance networks within a village in Tanzania; networks are not clustered but largely overlapping. We test...

Most studies fail to find an impact of school inputs on outcomes such as test scores. We argue that this might be a consequence of ignoring the possibility that households respond optimally to changes in school inputs and thus obscure the real effect of such provision on cognitive achievement....

We examine the effect of shocks to teacher inputs on child performance in school. We start with a household optimization framework where parents spend optimally in response to teacher and other school inputs. This helps to isolate the impact of teachers from other inputs. As a proxy measure for...

Empirical work in labour economics has focused on rent sharing as an explanation for the observed correlation in cross-sections between wages and profitability. The alternative explanation of risk sharing between workers and employers has not been tested. Using a unique panel data set for four...

Much has been written on the determinants of input and technology adoption in agriculture, with issues such as input availability, knowledge and education, risk preferences, profitability, and credit constraints receiving much attention. This paper focuses on a factor that has been less well...

We report on a randomized field experiment using price incentives to address both economic and gender inequality in land tenure formalization.  During the 1990s and 2000s, nearly two dozen African countries proposed de jure land reforms extending access to formal, freehold land tenure to...
