Efficient Bailouts?
构建量化均衡模型研究金融危机后救助措施对事前风险积累的影响,发现系统性救助的道德风险有限,而针对性救助会显著增加经济脆弱性。
We develop a quantitative equilibrium model of financial crises to assess the interaction between ex post interventions in credit markets and the buildup of risk ex ante. During a systemic crisis, bailouts relax balance sheet constraints and mitigate the severity of the recession. Ex ante, the anticipation of such bailouts leads to an increase in risk-taking, making the economy more vulnerable to a financial crisis. We find that moral hazard effects are limited if bailouts are systemic and broad-based. If bailouts are idiosyncratic and targeted, however, this makes the economy significantly more exposed to financial crises.
