Remittances Deteriorate Governance
利用油价驱动的汇款流入作为自然实验，研究发现汇款会恶化治理质量，尤其在民主制度薄弱的国家，汇款增加1个标准差使腐败指数上升1.5点，相当于人均GDP减少600美元。
Abstract I use a natural experiment of oil-price-driven remittance flows to poor, non-oil-producing Muslim countries to demonstrate that remittances deteriorate the quality of governance, especially in countries with weak democratic institutions. The results indicate that a 1 standard deviation increase in remittances raises corruption by 1.5 index points (on a 6-point scale), which is equivalent to a [dollar]600 decrease in per capita GDP. Concomitantly, remittances may enable governments to reduce their delivery of public services (for example, health care, school enrollment). The results suggest that political institutions may mediate the potentially beneficial socioeconomic effects of remittance inflows.
