US politics and World Bank IDA-lending
研究美国政治因素如何影响世界银行优惠贷款的分配，发现1993-2000年间美国通过联合国投票相似度对贷款分配有显著影响，且结果稳健。
This paper studies the role of US political factors in the allocation of World Bank concessional lending, where US political interests are proxied by voting similarity in the United Nations General Assembly on issues identified as important by the US Department of State. In contrast to previous studies we find that the US exerted a significant influence on IDA lending during the period 1993-2000. We demonstrate that the influence was both statistically as well as economically significant. Finally, we demonstrate that our result is robust with respect to the omission of the IDA Country Performance Rating index
