Previous research has associated citizens’ support for corrupt authorities with information deficiencies. This research offers an alternative perspective, suggesting that even well-informed citizens may support corrupt political figures who are seen as responsive to the constituency. Drawing upon the implicit exchange hypothesis, this study aims to examines the interactive effect of political corruption and political responsiveness on public trust. Survey data were collected from 590 small local business owners in two town municipalities in Thailand. Results showed that political corruption had a negative effect on public trust, whereas political responsiveness had a positive effect. Moreover, political responsiveness was found to neutralize the trust-eroding effect of political corruption, after controlling for the (interactive) effects of politicians’ perceived competence and local governance performance. These results paint a rather somber view, suggesting that, in the presence of political responsiveness, citizens may condone political corruption, allowing local politicians to maintain public trust even if they are seen as corrupt.
