Foreign aid is one of the most important policy tools that rich countries use for helping poor countries to improve population well-being and facilitate economic and institutional development. The empirical evidence on its benefits is mixed and has generated much controversy. This paper presents...

The literature on aid and growth has not found a convincing instrumental variable to identify the causal effects of aid. This paper exploits an instrumental variable based on the fact that since 1987, eligibility for aid from the International Development Association (IDA) has been based partly...

We examine the effects of aid on growth--in cross-sectional and panel data--after correcting for the bias that aid typically goes to poorer countries, or to countries after poor performance. Even after thiscorrection, we find little robust evidence of a positive (or negative) relationship...

We meta-analyze for impact and cost-effectiveness 94 studies from 47 conditional cash transfer (CCT) programs in low- and middle-income countries worldwide, focusing on educational outcomes that include enrollment, attendance, dropout and school completion. To conceptually guide and interpret...

Black markets are estimated to represent a fifth of global economic activity, but their response to policy is poorly understood because participants systematically hide their actions. It is widely hypothesized that relaxing trade bans in illegal goods allows legal supplies to competitively...

We study the impact of child labor standards in Regional Trade Agreements (RTAs) on a variety of child labor market outcomes, including employment, education, and household inequality. We develop a stylized general equilibrium model of child labor in an economy open to international trade and...

We evaluate the long-run effects of a decentralized approach to economic development, called community driven development (CDD), a prominent strategy for delivering foreign aid. Notably we revisit a randomized CDD program in Sierra Leone 11 years after launch. We estimate large persistent gains...
