Returns to International Migration: Evidence from a Bangladesh-Malaysia Visa Lottery
研究利用孟加拉国赴马来西亚临时劳工签证的随机抽签，发现中签者移民后收入翻三倍，汇款提高家庭生活水平，但移民缺席会暂停婚姻生育、降低家庭创业，而未能移民者的技能投资在国内无回报。
South Asians traveling to richer Asian nations is the world's largest migration corridor. We track down applicants to a government lottery that randomly allocated visas to Bangladeshis for temporary labor contracts in Malaysia, five years later. Most lottery winners migrate, and migrants' earnings triple. Their remittance raises their family's standard of living in Bangladesh. The migrant's absence pauses marriage and childbirth and shifts decision-making power toward females. Migration removes enterprising individuals, lowering household entrepreneurship, but does not crowd out other family members' labor supply. A deferred migration offer never materialized for a subgroup. Their premigration investments in skills generate no returns in the domestic market.
