An overlapping generations model of taxpayer bailouts of banks

The paper constructs an overlapping generations model to evaluate how different bank rescue plans affect banks’ risk-taking incentives. For a non-competitive banking industry, we find bailout with tax imposed on the old generation or equity bail-in to be efficient policies in the sense that they implement socially optimal risk-taking. In a competitive banking sector, no-bailout implements the socially-optimal risk-taking. Bailout policies financed by a tax imposed on the young generation always induce excessive risk-taking.
