In this paper we explore the possibility that differentials in corruption are causal to income inequality differences. Utilizing 61 countries in 2012, the OLS estimates suggest that ceteris paribus, corruption affects income inequality. Classifying 61 countries into three country groups(Korea, OECD and developing country groups), the effect of corruption on income inequality was estimated. The OLS estimates indicate that as a 10 points reduction in corruption equivalent to Spain will decrease income inequality by 3.01 points; if the level of corruption in Korea is equivalent to that in Spain, income inequality in Korea will be consistent with that in the UK. In order to relieve Korea's income inequality, therefore, the policy makers should reduce corruption through public sector efficiency improvement as well as strict detection and law enforcement.??? ????????? 2012??? ??????(?????????????????????)??? ???????????? ????????????????????? ????????? ?????? ????????? ?????????(NRF-2012S1A3A2033350)
