Cash Transfers and Migration: Theory and Evidence from a Randomized Controlled Trial
研究了科摩罗的以工代赈项目是否增加国际移民，发现现金转移通过缓解流动性和风险约束使移民率从7.8%升至10.8%。
Abstract Will the fast expansion of cash-based programming in poor countries increase international migration? Theoretically, cash transfers may deter migration by increasing its opportunity cost or favor migration by relaxing liquidity, credit, and risk constraints. This paper evaluates the impact of a cash-for-work program on migration. Randomly selected households in Comoros were offered up to US$320 in cash in exchange for their participation in public works projects. We find that the program increased international migration by 38% from 7.8% to 10.8%. The increase in migration appears to be driven by the alleviation of liquidity and risk constraints.
