The purpose of this study is to examine whether nepotism has influences on public servant corruption. A target group of empirical research is various personal relations of high position public servants (i.e. more than assistant secretary level) and their level of corruption in the current Lee Administration. The study divided the corruption into two types, individual corruption and power-related corruption to check which one has associated with nepotism. The main findings of the study are; 1) personal relations built in the previous job seem to have more association with corruption than alumni relations or region-related relations, 2) while nepotism is closely associated with power-related corruption, it does not have influence on individual corruption, and 3) public servants whose background is merit system showed far less degree of both individual and power-related corruption than those appointed by spoils system.
