Irregular migration from West Africa to Europe across the Sahara and Mediterranean is extremely risky for migrants and a key policy concern. A cluster-randomized experiment with 3,641 young men from 391 settlements in The Gambia is used to test three approaches to reducing risky migration:...

The COVID-19 pandemic has resulted in border closures in many countries and a sharp reduction in overall international mobility. However, this disruption of legal pathways to migration has raised concerns that potential migrants may turn to irregular migration routes as a substitute. We examine...

Over 200 million people live outside their country of birth and experience large gains in material well-being by moving to where wages are higher. But the effect of this migration on health is less clear and existing evidence is ambiguous because of the potential for self-selection bias. In this...

We use an original panel dataset of migrant departures from the Philippines to identify the responsiveness of migrant numbers and wages to GDP shocks in destination countries. We find a large significant elasticity of migrant numbers to GDP shocks at destination, but no significant wage...

The majority of firms in most developing countries are informal. We conducted a field experiment in Sri Lanka which provided incentives for informal firms to formalize. Offering only information about the registration process and reimbursement for direct registration costs had no impact on...
