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...

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...

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...

Developing countries invest in training skilled workers and can lose part of their investment if those workers emigrate. One response is for the destination countries to design ways to participate in financing skilled emigrants' training before they migrate — linking skill creation and skill...

While measured remittances by migrant workers have soared in recent years, macroeconomic studies have difficulty detecting their effect on economic growth. We review existing explanations for this puzzle and propose three new ones. First, we offer evidence that a large majority of the recent...

It is time to fundamentally reframe the research agenda on remittances, payments, and development. We describe many of the research questions that now dominate the literature and why they lead us to uninformative answers. We propose reasons why these questions dominate, the most important of...
