This paper compares the relative impact of two road safety interventions in the Kenyan minibus or matatu sector: a top down set of regulatory requirements known as the Michuki Rules and a consumer empowerment intervention. We use very detailed insurance claims data on three classes of vehicles...

In economies with weak enforcement of traffic regulations, drivers who adopt excessively risky behavior impose externalities on other vehicles, and on their own passengers. In light of the difficulties of correcting inter-vehicle externalities associated with weak third-party enforcement, this...

We report the results of a randomized field experiment aimed at improving the safety of long-distance mini-busses or matatus in Kenya. Our intervention combines evocative messages aimed at motivating passengers to speak up against bad driving with a lottery that rewards matatu drivers for...

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 show that pregnant women whose first clinic visit coincides with the nurse's attendance are 58 percentage points more likely to test for HIV and 46 percent more likely to deliver in a hospital. Furthermore, women with high pretest expectations of being HIV positive, whose visit coincides with...

Empirical studies of the relationship between school inputs and test scores typically do not account for household responses to changes in school inputs. Evidence from India and Zambia shows that student test scores are higher when schools receive unanticipated grants, but there is no impact of...

A large literature examines the link between shocks to households and the educational attainment of children. The authors use new data to estimate the impact of shocks to teachers on student learning in mathematics and English. Using absenteeism in the 30 days preceding the survey as a measure...
