Labor markets in developing countries are subject to a high degree of frictions. We report the results from a randomized evaluation of an adult education program (Project ABC) in Niger, in which students learned how to use simple mobile phones as part of a literacy and numeracy class. Overall,...

This paper critiques the last decade of research on the effects of high-skill emigration from developing countries, and proposes six new directions for fruitful research. The study singles out a core assumption underlying much of the recent literature, calling it the Lump of Learning model of...

Immigration officials in rich countries are being asked to become overseas development officials, charged with preventing skilled workers from leaving poor countries, where their skills are needed. Some advocates urge restrictions or taxes on the emigration of doctors and engineers from...

Skilled workers emigrate from developing countries in rising numbers, raising fears of a drain on the human and financial resources of the countries they leave. This paper critiques existing policy proposals to address the development effects of skilled migration. It then proposes a new kind of...

The effect of foreign labor on native employment within an occupation depends on native labor supply to that occupation which is rarely directly measured even if native and foreign labor are perfect substitutes in production. This paper uses two natural quasi-experiments to directly compare...

An important class of active labor market policy has received little rigorous impact evaluation: immigration barriers intended to improve the terms of employment for domestic workers by deliberately shrinking the workforce. Recent advances in the theory of endogenous technical change suggest...

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...
