Unilateral Facilitation Does Not Raise International Labor Migration from the Philippines
通过菲律宾大规模随机实验发现，单方面促进劳务移民的政策虽能提高海外工作机会，但对实际移民人数无显著影响，表明此类措施效果有限。
Significant income gains from migrating from poorer to richer countries have motivated unilateral (source-country) policies facilitating labor emigration. However, their effectiveness is unknown. We conducted a large-scale randomized experiment in the Philippines testing the impact of unilaterally facilitating international labor migration. Our most intensive treatment doubled the rate of job offers but had no identifiable effect on international labor migration. Even the highest overseas job-search rate we induced (22%), falls far short of the share initially expressing interest in migrating (34%). We conclude that unilateral migration facilitation will at most induce a trickle, not a flood, of additional emigration.
