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...

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 literature and recent data suggest something quite different: that over the...

"Guest workers" earn higher wages overseas on temporary low-skill employment visas. This wage effect can quantify global inefficiencies in the pure spatial allocation of labor between poorer and richer countries. But rigorous estimates are rare, complicated by migrant self-selection. This paper...

A recent surge in child migration to the U.S. 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 region....

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...

Many governments seek to reduce emigration from low-income countries by encouraging economic development there. A large literature, however, observes that average emigration rates are higher in countries with sustained increases in GDP per capita than in either chronically poor countries or...

We report a small-sample, preliminary evaluation of the economic impact of temporary overseas work by Haitian agricultural workers. This work occurs in the United States in the context of a pilot program designed as a form of post-disaster development assistance to Haiti. We find that the...

Countries restrict the overall extent of international travel and migration to balance the expected costs and benefits of mobility. Given the ever-present threat of new, future pandemics, how should permanent restrictions on mobility respond? A simple theoretical framework predicts that reduced...
