The Long-term Impacts of International Migration: Evidence from a Lottery
通过比较移民抽签项目中成功与未成功者近十年后的结果，发现移民长期收入增长与首年相当，且显著提升了直系亲属的消费、资产、储蓄和饮食多样性，但对大家庭无显著影响。
We examine the long-term impacts of international migration by comparing immigrants who had successful ballot entries in a migration lottery program, and first moved almost a decade ago, with people who had unsuccessful entries into those same ballots. The long-term gain in income is found to be similar in magnitude to the gain in the first year despite migrants upgrading their education and changing their locations and occupations. This results in large sustained benefits to their immediate family who have substantially higher consumption, durable asset ownership, savings, and dietary diversity. In contrast we find no measureable impact on extended family.
