I investigate whether a school-based deworming intervention in Kenya had long-term effects on young children in the region. I exploit positive externalities from the program to estimate impacts on younger children who were not directly treated. Ten years after the intervention, I find large cognitive effects—comparable to between 0.5 and 0.8 years of schooling—for children who were less than on...

This paper considers the impact of community participation on outcomes of development projects. It Ž rst offers a theoretical framework for participation by using the property rights literature to model how participation in an activity, in addition to involving information exchange, also results in greater in uence in the activity. The model predicts that community participationmay not always ...

Micro-entrepreneurs often lack the financial literacy required for the complex financial decisions they face. We conduct a randomized control trial with a bank in the Dominican Republic to compare the impact of two distinct programs: a standard accounting training versus a simplified, rule-of-thumb training that teaches basic financial heuristics. Only the latter produced significant improvemen...

There is a burgeoning literature highlighting asymmetric information among household members. However, little is known about the source of the asymmetry and its effect on efficiency. Using a unique survey of Ghanaian households, we examine the accuracy of spousal cross-reports and the effect of discrepancies on farm production. We find that information problems pertain to scale, the quantity of...

Radiation effects in cerium doped Gd 3 (Al,Ga) 5 :O 12 (or GGAG) single crystals irradiated by swift heavy ions with fluences ranging from 6·10 10 to 2·10 ions/cm 2 have been studied. A stable strong induced absorption observed the spectral range 200–350 nm correlates irradiation fluence. It is suggested that several centers are responsible for this GGAG and their possible origin (F-type V-cent...
