This paper explores whether one of the most important U.S. policies towards Africa of the past few decades achieved its desired result. In 2000, the United States dropped trade restrictions on a broad list of products through the African Growth and Opportunity Act (AGOA). Since the Act was...

The Millennium Development Goals call for reducing by half the proportion of people without sustainable access to safe drinking water. This goal was adopted in large part because clean water was seen as critical to fighting diarrheal disease, which kills 2 million children annually. There is...

How well do countries cope with the aftermath of natural disasters? In particular, do international financial flows help buffer countries in the wake of disasters? This paper focuses on hurricanes (one of the most common and destructive types of disasters), and examines the impact of hurricane...

Using longitudinal survey data collected in collaboration with a treatment program, this paper is the first to estimate the economic impacts of antiretroviral treatment in Africa. The responses in two important outcomes are studied: (1) labor supply of adult AIDS patients receiving treatment;...

We examine one of the most important and intriguing puzzles in economics: why it is so hard to find a robust effect of aid on the long-term growth of poor countries, even those with good policies. We look for a possible offset to the beneficial effects of aid, using a methodology that exploits...

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...

The current level and form of subsidization of college education is often rationalized by appeal to capital constraints on individuals. Because borrowing against human capital is difficult, capital constraints can lead to nonoptimal outcomes unless government intervenes. We develop a simple...

The history of foreign development assistance is one of movement away from addressing immediate needs and toward focusing on the underlying causes of poverty. A recent manifestation is the move towards sustainability,' which stresses community mobilization, education, and cost-recovery. This...

The Pell Grant program is the largest means-tested financial assistance available to postsecondary students across the United States, yet researchers have only limited evidence on the causal effects of these grants. This paper examines the effect of Pell grants on student persistence after the...

Debt relief is unlikely to stimulate investment and growth in the world's highly indebted poor countries (HIPCs). This is because the HIPCs do not suffer from debt overhang. The principal obstacle to investment and growth in the world's poorest countries is a lack of basic economic institutions...
