The typical identification strategy in aid effectiveness studies assumes donor motives do not influence the impact of aid on growth. We call this homogeneity assumption into question, first constructing a model in which donor motives matter and then testing the assumption empirically.

This paper explores empirical aspects of the relation between supervision and project performance. I focus on development projects funded by the World Bank and on supervision done by the World Bank. The World Bank is the preeminent international development organization both in terms of money...

This paper explores how U.S. bilateral economic aid has or has not changed with the advent of the War on Terror. In particular, has the renewed geopolitical role of aid coincided with a reduction of aid to the poorest countries or less weight on need in U.S. aid allocation decisions? We start...

This paper assesses the impact of World Bank project preparation on project outcomes. Using a stochastic frontier model, I generate a measure of World Bank project preparation duration based on variation in political economy factors that are otherwise exogenous to project outcomes. Panel...
