Do Migrants Improve Governance at Home? Evidence from a Voting Experiment
通过一项邮寄明信片的投票实验，衡量民众对政治问责的需求，发现国际移民（尤其是来自治理较好国家的回流移民）能显著提升母国对更好治理的诉求。
Can international migration promote better institutions at home by raising the demand for political accountability? A behavioral measure of the population's desire for better governance was designed to examine this question. A postcard was distributed to households promising that if enough postcards were mailed back, results from a survey module on perceived corruption would be published in the national media. Data from a tailored household survey were used to examine the determinants of this behavioral measure of demand for political accountability (undertaking the costly action of mailing the postcard) and to isolate the positive effect of international emigration using locality-level variation. The estimated effects are robust to the use of instrumental variables, including past migration and macro shocks in the destination countries. The estimated effects can be attributed mainly to migrants who emigrated to countries with better governance, especially migrants who return home.
