Labor markets are increasingly global. Overseas work can enrich households but also split them geographically, with ambiguous net effects on decisions about work, investment, and education. These net effects, and their mechanisms, are poorly understood. We study a policy discontinuity in the...

The emigration of highly skilled workers can in theory lower social welfare in the migrant-sending country. If such workers produce a good whose consumption conveys a positive externality - such as nurses and doctors in a very poor country - the loss can be greater, and welfare can even decline...

Rich countries have made efforts for half a century to help people in poor countries catch up to rich-country standards of living. Those efforts have included giving foreign aid, encouraging overseas investment, dismantling trade barriers, and spreading ideas and institutions. That is, their...

Past research on aid and growth is flawed because it typically examines the impact of aggregate aid on growth over a short period, usually four years, while significant portions of aid are unlikely to affect growth in such a brief time. We divide aid into three categories: (1) emergency and...

Raising school enrollment, like economic development in general, takes a long time. This is partly because, as a mountain of empirical evidence now shows, economic conditions and slowly-changing parental education levels determine children's school enrollment to a greater degree than education...

Despite the large individual benefits of guest work by the poor in rich countries, agencies charged with global poverty reduction do little to facilitate guest work. This may be because guest work is viewed as a repugnant transaction—one whose harmful side-effects might cause third parties to...

Research on migration and development has recently changed, in two ways. First, it has grown sharply in volume, emerging as a proper subfield. Second, while it once embraced principally rural-urban migration and international remittances, migration and development research has broadened to...

The most basic economic theory suggests that rising incomes in developing countries will deter emigration from those countries, an idea that captivates policymakers in international aid and trade diplomacy. A lengthy research literature and recent data suggest something quite different: that...

An influential strand of research has tested for the effects of immigration on natives' wages and employment using exogenous refugee supply shocks as natural experiments. Several studies have reached conflicting conclusions about the effects of noted refugee waves such as the Mariel Boatlift in...

A recent surge in child migration to the United States from Honduras, El Salvador, and Guatemala has occurred in the context of high rates of regional violence. But little quantitative evidence exists on the causal relationship between violence and international emigration in this or any other...
