Lobbying by Ethnic Groups and Aid Allocation
构建了一个政治经济模型，分析捐助国族群通过游说影响对外援助分配，发现受援国及族群的人均收入是关键因素，并考察腐败、援助疲劳和族群构成变化的影响。
We develop a political-economic model of foreign aid allocation. Each ethnic group in the donor country lobbies the government for allocating more aid to its country of origin, and the government accepts contributions from lobby groups. Initial per-capita income of the recipients and those of the ethnic groups are shown to be important determinants of the solution of the political equilibrium. We also examine the e®ects of changes in the degree of corruption, aid fatigue, and ethnic composition, in the donor country on the allocation of aid.
