The impact of the Paycheck Protection Program on the risk-taking behaviour of US banks
研究了美国薪资保护计划（PPP）对社区银行风险承担行为的影响，发现参与该计划导致社区银行在计划外降低风险偏好，这与它们受疫情重创的商业地产贷款敞口较大有关。
Abstract The economic impact of the COVID-19 pandemic placed many small businesses across the US in financial distress. In response to this, in March 2020 the US government introduced, as part of the CARES Act, the Paycheck Protection Program (PPP) intended to provide relief to small businesses and to preserve jobs during the pandemic. The latter resulted in three waves of funding distributed to small businesses through SBA approved lenders, mainly represented by US banks. By using a panel dataset of 4610 banks over the period Q1 2019–Q4 2020 and by employing a difference-in-differences approach (DiD), I investigate whether participation in the Paycheck Protection Program affected community banks’ credit risk-taking behaviour in the post-PPP period, compared to their non-community banking counterparts in the US. I find that the Paycheck Protection Program led community banks to decrease their risk appetite outside of the program relative to non-community banks, consistent with their greater exposure to the commercial real estate sector, heavily hit by the pandemic. My results are robust to a battery of robustness tests and identification strategies. In this research article, I offer novel evidence on the indirect impact of the Paycheck Protection Program as a government-funded stimulus program administered through banks by investigating the indirect effect of the Paycheck Protection Program on the risk-taking of US community banks that dominate lending of PPP loans as a result of their competitive advantage in soft information-intensive small business lending. Such evidence is informative to policymakers as they weigh the merits of various program options to combat the economic damage imposed by the COVID-19 pandemic and as they consider the design of economic stimulus programs in response to future economic crises.
