Democracy and Aid Donorship
研究了民主制度对不同收入国家设立对外援助项目的影响，发现民主在富国促进援助项目设立，在穷国则起阻碍作用。
Almost half of the world’s states provide bilateral development assistance. While previous research takes the set of donor countries as exogenous, this article introduces a new dataset on aid giving that covers all countries in the world, both rich and poor, and explores the determinants of aid donorship. It argues and shows empirically that democratic institutions support the setup of an aid program in richer countries but undermine its establishment in poorer countries. The findings hold in instrumental-variable regressions and the pattern is similar for the amount of aid.
