Significant income gains from migrating from poorer to richer countries have motivated unilateral (source-country) policies facilitating labor emigration. However, their effectiveness is unknown. The authors conducted a large-scale randomized experiment in the Philippines testing the impact of...

East and Southeast Asia face major demographic changes over the next few decades as many countries' labor forces will start to decline, while others will experience higher labor force growth as populations and participation rates increase. A well-managed labor migration strategy presents itself...
