Hometown Favoritism and Political Rewards: Evidence From South Korean Municipalities

We examine whether politicians favor their hometowns in the allocation of transfers as a strategy to reward core supporters. In South Korea, regional governors have discretion to allocate certain grants to municipalities without approval from the legislature. Using data from 226 South Korean municipalities across 15 regions, we find that the hometowns of internal governors, those elected within their home regions, receive approximately 20% more discretionary grants. Consistent with the core supporter model, we show that elected internal governors allocate more grants to hometown municipalities with a higher concentration of supporters. In contrast, external governors, those elected outside their home regions, exhibit no hometown bias. Our findings suggest that regional governors favor their hometowns because these areas tend to provide strong electoral support.
