The COVID-19 pandemic, with its heavy toll on human lives, unemployment, and financial distress, should be considered as an important acid test for firms’ professed investments in their responsibility toward society. It is during such times that we can better understand how to interpret the Environmental, Social, and Governance (ESG) scores, standard proxies for firms’ corporate social responsibility, and what is really driving them. The paper “Resiliency of Environmental and Social Stocks: An Analysis of the Exogenous COVID-19 Market Crash,” by Rui Albuquerque, Yrjo Koskinen, Shuai Yang, and Chendi Zhang, has this objective. The authors show that U.S. firms with higher Environmental and Social (ES) scores were more resilient during the COVID-19 induced stock market crash: these stocks suffered lower stock price declines and lower volatility compared to other firms. The authors then investigate how ES policies build resiliency and look at theories of customer and investor loyalty. Firms with high customer and investor loyalty experienced the strongest stock price performance. Customer loyalty translated into higher operating profit margins of firms with high ES scores, even at a time when the economy as a whole was suffering through the first stages of a contraction. Overall, the results in the paper lend support to the view that consumer and investor loyalty play important roles in making high ES firms more resilient during stressful times.

Paper Spotlight: Managerial Attributes, Incentives, and Performance

Jeffrey L. Coles

Zhichuan (Frank) Li

The determinants of executive compensation packages are fraught with empirical difficulties due to unobserved firm-level, CEO-level, and assortative matching characteristics. In the paper “Managerial Attributes, Incentives, and Performance,” just published in the August 2020 issue (Volume 9, Issue 2), Jeff Coles and Frank Li examine the relative importance of observable and unobservable firm- and manager-specific characteristics in determining two fundamental attributes of executive incentives, delta and vega. They find that manager fixed effects, that can capture managerial talent and risk aversion, account for a very significant portion of the variation in these executive incentives. This result is important because it sheds light on the limitations of empirical investigation on executive compensation so far: it is hard to find appropriate and comprehensive measures of these managerial characteristics among the observable managerial characteristics used in the existing literature. Jeff and Frank also find that managerial fixed effects of these compensation incentives could explain future firm policy, risk, and performance. It is quite surprising that some established relationships between executive incentives and firm outcomes are indeed driven by the manager-fixed-effects portions of delta and vega only. Importantly, the significant relative explanatory power of unobserved managerial heterogeneity found in this paper would suggest that both theoretical and empirical work will benefit from focusing on the roles and attributes of top managers.

RCFS Blog Series II: Banks’ Contingent Capital Trigger Effects

In the RCFS blog, Professor Ellul discusses Boris Vallée‘s paper “Banks’ Contingent Capital Trigger Effects,” which won the RCFS’s 2020 Rising Scholar Award. Vallée finds that liability management exercises, a type of contingent capital trigger used by banks, are effective at improving banks’ capitalization levels. This finding is particularly important during the COVID-19 pandemic, when economic downturn is likely to put pressure on banks. Read the full post on the blog.

Paper Spotlight: Identifying the Real Effects of Zombie Lending

Fabiano Schivardi

Enrico Sette

Guido Tabellini








The impact of COVID-19 has driven many firms into financial distress, and policymakers around the world have responded with various emergency measures to support the business sector. While the immediate priority has been to get support out quickly to firms, over time more active decisions will have to be made on which firms should be supported. A potential danger that arises is that firms that should be allowed to shut down are kept alive as “zombie firms” through the provision of subsidized financing. The literature has found that diverting resources to zombie firms has a negative effect on healthy firms in the same industry. However, in the paper “Identifying the Real Effects of Zombie Lending,” Fabiano Schivardi, Enrico Sette, and Guido Tabellini argue that the literature may suffer from a serious identification problem. Often implicitly, and sometimes explicitly, firm performance is used to identify zombie firms. This is problematic, because a downturn in an industry may be associated with both declining performance of healthy firms and a narrowing of the performance gap between healthy and weak firms. There will therefore be a bias toward finding that healthy firms too suffer in a sector with a high proportion of zombie firms. In analyzing the effects of COVID-19, determining the extent to which zombie financing is a problem will be an important issue both for policymakers and for researchers.
