Bailouts, Contagion, and Bank Risk-Taking
We revisit the link between bailouts and bank risk taking. The expectation of government support to failing banks (bailout) creates moral hazard and encourages risk-taking. However, when a bank's success depends on both its idiosyncratic risk and the overall stability of the banking system, a government's commitment to shield banks from contagion may increase their incentives to invest prudently. We explore these issues in a simple model of financial intermediation where a bank's survival depends on another bank's success. We show that the positive effect from systemic insurance dominates the classical moral hazard effect when the risk of contagion is high.
