Corruption and Growth
利用跨国数据，发现腐败通过降低投资来抑制经济增长，并通过民族语言分化指数作为工具变量控制内生性，结果稳健。
This paper analyzes a newly assembled data set consisting of subjective indices of corruption, the amount of red tape, the efficiency of the judicial system, and various categories of political stability for a cross section of countries. Corruption is found to lower investment, thereby lowering economic growth. The results are robust to controlling for endogeneity by using an index of ethnolinguistic fractionalization as an instrument.
