Does CSR matter in times of crisis? Evidence from the COVID-19 pandemic

The debate over how firm stakeholder engagement is tied to preserving shareholder wealth has received growing attention in recent years, especially in the wake of the COVID-19 crisis. Against this backdrop, we examine the relation between corporate social responsibility (CSR) and stock market returns during the COVID-19 pandemic-induced market crash and the post-crash recovery. Using a sample of 1750 U.S. firms and two major sources of CSR ratings, we find no evidence that CSR affected stock returns during the crash period. This result is robust to various sensitivity tests. In additional cross-sectional analysis, we find some supporting evidence, albeit weak, that the relation between CSR and stock returns during the pandemic-related crisis is more positive when CSR is congruent with a firm's institutional environment. We also find that Business Roundtable companies, which committed to protecting stakeholder interests prior to the pandemic, do not outperform during the pandemic crisis. We conclude that pre-crisis CSR is not effective at shielding shareholder wealth from the adverse effects of a crisis, suggesting a potential disconnect between firms' CSR orientation (ratings) and actual actions. Our evidence suggests that investors can distinguish between genuine CSR and firms engaging in cheap talk.     

The 2008 financial crisis: Stock market contagion and its determinants

In this paper, we investigate worldwide contagion and its determinants during the 2008 financial crisis. Utilizing an international sample of returns from 2003 to 2009, we consider both uni- and bi-directional contagion. After controlling for crisis-related volatility, we find strong evidence that cross-market linkages increase among many financial markets. In contrast to previous crises, contagion following the 2008 global financial crisis is not confined to emerging markets. The United States and other mature financial markets in the sample transmit and receive contagion. Country markets are less influenced by regions than they are by other country markets. We also construct variables that represent relative changes in economic variables before and during the crisis. We find that both economic fundamentals such as trade structure, interest rates, inflation rates, industrial production, and regional effects, and investors’ risk aversion contribute to international contagion.     

Financial contagion effects of major crises in African stock markets

This study examines financial contagion effects in African stock markets during major crises over the period 2005 to 2020. We investigate contagion effects in individual stock markets and from a regional perspective using dynamic conditional correlations during the global financial crisis, European debt crisis, Brexit, and COVID-19. The empirical evidence confirms contagion effects in some individual markets. However, significant evidence of contagion is found only during the global financial crisis from the regional perspective. Our findings suggest that the regional impacts of crises differ due to the nature of those crises. We also find financial contagion increases in the country-level risk, market capitalization and export to GDP and decreases in corruption.     

Crude oil market and stock markets during the COVID-19 pandemic: Evidence from the US,Japan, and Germany

We analyzed the return and volatility spillover between the COVID-19 pandemic in 2020, the crude oil market, and the stock market by employing two empirical methods for connectedness: the time-domain approach developed by Diebold and Yilmaz (2012) and the method based on frequency dynamics developed by Barunik and Krehlik (2018). We find that the return spillover mainly occurs in the short term; however, the volatility spillover mainly occurs in the long term. From the moving window analysis results, the impact of COVID-19 created an unprecedented level of risk, such as plummeting oil prices and triggering the US stock market circuit breaker four times, which caused investors to suffer heavy losses in a short period. Furthermore, the impact of COVID-19 on the volatility of the oil and stock markets exceeds that caused by the 2008 global financial crisis, and continues to have an effect. The impact of the COVID-19 pandemic on financial markets is uncertain in both the short and long terms. Our research provides some urgent and prominent insights to help investors and policymakers avoid the risks in the crude oil and stock markets because of the COVID-19 pandemic and reestablish economic development policy strategies.     

Multilayer information spillover networks between oil shocks and banking sectors: Evidence from oil-rich countries

There is no doubt that oil price shocks significantly affect oil-producing countries' macroeconomic fundamentals and financial stability, mainly in crisis times. The recent oil price shocks, coupled with the COVID-19 pandemic, motivated us to investigate the connectedness and risk transmission among oil shocks and banking sectors in the Gulf Cooperation Council (GCC) economies from June 30, 2006, to September 9, 2021. Thus, we construct multilayer information spillover networks between oil price shocks and GCC banking sectors. The empirical results show that the Bahrain banking sector depicts the highest connectedness and risk transmission with oil price shocks on the extreme risk spillover layer. In addition, Kuwait and the United Arab Emirates are highly connected to oil demand shocks. Furthermore, we find a substantial increase in extreme risk spillover and volatility spillover layers during the COVID-19 period. The results of this paper have some important implications for regional portfolio risk management, alleviating systemic risk, and developing hedging and investment strategies.     

Corporate governance in the 2007–2008 financial crisis: Evidence from financial institutions worldwide

This paper investigates the influence of corporate governance on financial firms' performance during the 2007–2008 financial crisis. Using a unique dataset of 296 financial firms from 30 countries that were at the center of the crisis, we find that firms with more independent boards and higher institutional ownership experienced worse stock returns during the crisis period. Further exploration suggests that this is because (1) firms with higher institutional ownership took more risk prior to the crisis, which resulted in larger shareholder losses during the crisis period, and (2) firms with more independent boards raised more equity capital during the crisis, which led to a wealth transfer from existing shareholders to debtholders. Overall, our findings add to the literature by examining the corporate governance determinants of financial firms' performance during the 2007–2008 crisis.     

Can hedge funds time global equity markets? Evidence from emerging markets

This paper examines the ability of global hedge funds to time a particularly volatile asset class — emerging market equities. In particular, we study whether or not these funds can either time emerging markets as a whole, or time their exposures to different regions. Using both pooled and calendar-time approaches, we generally find no evidence of overall timing ability. However, we do find some evidence of period-specific timing ability during the financial crisis and subsequent recovery.     

Pandemic-driven financial contagion and investor behavior: Evidence from the COVID-19

This paper studies the pandemic-driven financial contagion during the COVID-19 period and the impact of investor behavior on it by constructing three types of direct behavior measurements based on Google search volumes. More specifically, using a sample of 26 major stock markets around the world during the COVID-19 pandemic, we construct a non-linear financial contagion network via a dynamic mixture copula-EVT (extreme value theory) model to quantitatively detect and measure the complex nature of pandemic-driven financial contagion. Furthermore, through constructing direct investor behavior measurements including investor attention, sentiment, and fear, we find investor behavior plays an important role in explaining pandemic-driven financial contagion. We also find that the impacts of investor behavior on the pandemic-driven financial contagion are heterogeneous under several different settings, including market conditions, market development levels, regional subsets, and contagion directions.     

Investor attention and global market returns during the COVID-19 crisis

The financial market response to the COVID-19 pandemic provides the first example of a market crash instigated by a health crisis. As such, the crisis provides a unique setting in which to examine the market response to changes in investor attention. We utilise Google search volume (GSV) as a proxy for investor attention. GSV for the “coronavirus” keyword increases markedly from late-February and peaks in mid-March before declining substantially. Our results are broadly consistent with Da, Engelberg, and Gao (2015), indicating that GSV is primarily a proxy for the attention of retail investors and confirming that investor attention negatively influences global stock returns during this crisis period. A rise in the number of internet searches during the COVID-19 crisis induces a faster rate of information flow into financial markets and so is also associated with higher volatility. The identified relationships are economically and statistically significant even after controlling for the number of COVID-19 cases and macroeconomic effects. Increases in GSV have less impact on government bond yields where the limited role of GSV is likely due to lower participation of retail investors. The results suggest that, rather than searching for information on potential stocks to buy (Barber & Odean, 2008), retail investors are searching for information to resolve uncertainty about household FEARS (Da et al., 2015) during the COVID-19 crisis.     

Does real flexibility help firms navigate the COVID-19 pandemic?

Building on the investment-based asset pricing framework, we show that firms' ability to timely scale down their operations reduces the sensitivity of their equity value to large adverse productivity shocks. Using U.S. data in the times of the COVID-19 pandemic, we provide empirical evidence consistent with our model's predictions. Real flexibility curbs losses in firm value and reduces return volatility, especially for firms with high book-to-market or high COVID-19 exposure, consistent with the idea that the benefits of real flexibility are associated primarily with contraction options during the COVID-19 crisis. Our analysis shows that real flexibility provides incremental and complementary protection beyond financial flexibility. Besides its impact on stock prices, real flexibility also helps firms sustain earnings during 2020, compared with 2019 when the pandemic had not struck. Our work demonstrates that real flexibility is an important tool for corporate managers in navigating episodes of disasters.     

COVID-19, policy interventions and credit: The Brazilian experience

The COVID-19 pandemic caused a global health and economic crisis to which governments responded with massive policy interventions. Using Brazil as a testing ground, we investigate the influence of the pandemic and ensuing policy interventions on local credit markets. First, we find that the pandemic has a significantly negative impact on local credit. Second, using a novel manually collected database on the staggered municipal government policy interventions, we show heterogenous effects of interventions: positive effects of soft interventions (e.g., social distancing and mass gathering restrictions) and late reopening, and negative effects of hard interventions (e.g., closure of non-essential services) and early reopening. Third, we find that state-owned banks grant more local credit than privately owned banks during the COVID-19 crisis but this difference is less pronounced than it was in the 2008 Financial Crisis. We confirm our results using pre-pandemic local political preference as instrument for policy interventions and orthogonalized policy intervention indicators, and in placebo tests.     

Did family firms perform better during the financial crisis? New insights from the S&P 500 firms

This paper provides new evidence on whether family firms performed better during the global financial crisis (2008–2010). Using the dataset of the S&P 500 nonfinancial firms during the period 2006–2010, we find that family firms outperformed nonfamily firms during the crisis. Among family firms, the ones that contributed to the outperformance were those where the founder was still present. We also find that during the global financial crisis, founder firms invested significantly less and had better access to the credit market than nonfamily firms. Our analysis suggests that the superior performance of founder firms is largely caused by their having less incentive to overinvest in order to boost short-term earnings during the crisis.     

COVID-19 and Inequalities*

This paper brings together evidence from various data sources and the most recent studies to describe what we know so far about the impacts of the COVID-19 crisis on inequalities across several key domains of life, including employment and ability to earn, family life and health. We show how these new fissures interact with existing inequalities along various key dimensions, including socio-economic status, education, age, gender, ethnicity and geography. We find that the deep underlying inequalities and policy challenges that we already had are crucial in understanding the complex impacts of the pandemic itself and our response to it, and that the crisis does in itself have the potential to exacerbate some of these pre-existing inequalities fairly directly. Moreover, it seems likely that the current crisis will leave legacies that will impact inequalities in the long term. These possibilities are not all disequalising, but many are.     

Dividends and share repurchases during the COVID-19 economic crisis

In this article, we examine dividends and share repurchases of S&P 1500 firms during the COVID-19 crisis characterized by the stock market crash and a relatively quick stock price recovery propelled by technology stocks. We find that the great majority of firms either maintain or increase the level of dividends during the crisis period. Yet, the relation between the dividend payout and reported earnings is negative and significant. This relation also holds for other types of payouts, including share repurchases and special dividends. Moreover, we find that both forecasted and realized earnings of up to 1 year into the future are negatively associated with current dividends, implying that existing payout policies are unsustainable in the longer term. Surprisingly, the difference-in-differences test shows that firms strongly affected by the COVID-19 crisis have higher dividend payouts (relative to net earnings) compared to unaffected firms. The same test indicates that strongly affected firms significantly reduce repurchases.     

COVID-19 and time-frequency connectedness between green and conventional financial markets

Against the backdrop of the exponentially growing trend in green finance investments and the calls for green recovery in the post-COVID world, this study presents the time-frequency connectedness between green and conventional financial markets by using the spillover models of Diebold and Yilmaz (2012) and Baruník and Křehlík (2018). Covering a sample period from January 01, 2008, to July 31, 2020, we aim to explore the dynamics of connectedness between conventional and green investments in fixed income, equity, and energy markets. Additionally, we determine the role of market-wide uncertainty in altering the connectedness structure by performing a subsample analysis for the ongoing COVID-19 pandemic crisis period. Our results show that competing energy investments are not connected, and there is only one-way spillovers from the conventional bonds in the fixed-income investments. Additionally, we observe a low (high) intergroup connectedness for conventional (green) investments. Moreover, the frequency-based analysis shows that connectedness between these competing markets is more pronounced during the short-run. The subsample analysis for the pandemic crisis period shows similar results except for the disconnection between bond markets in the short-run frequency. Our time-varying analysis shows peaks and troughs in the connectedness between climate-friendly and conventional investments that suggest different global events such as the Eurozone Debt Crisis and Shale Oil Revolution drives the association between alternate investments. Similarly, we observe an enhanced connectedness during the recent COVID-19 period, suggesting that financial stability would be a significant factor in determining the smooth transition to green investments.     

Asian financial integration: Global or regional? Evidence from money and bond markets

This paper investigates the degree of global versus regional financial integration in Southeast Asia during the period 2004–2012. We examine integration in the money and bond markets in Asia by employing a covered-interest-parity-based measure of financial integration. The impact of the 2008 financial crisis as well as the recent regional bond initiatives on the integration process of Asian money and bond markets respectively are specifically investigated. Empirically, we adopt the Phillips and Sul (2007) convergence methodology that has not been previously employed to examine the integration process in Asian money and bond markets. We find evidence of both global and regional integration in the money market pre 2008 but once the crisis hit, the process of global integration comes to an abrupt halt. However, regional integration, albeit at a slower pace, is still clearly evident in the post-crisis period. As for the Asian bond market, evidence of both global and regional integration is found but, in comparison, the latter is more convergent post 2008. Regional integration is stronger when interest rates with longer maturity are considered. In addition, we identify some convergent subgroups of countries and this suggests that a multi-tiered style of convergence is present.     

COVID-19 Sentiment and the Chinese Stock Market: Evidence from the Official News Media and Sina Weibo

This study quantitatively measures the Chinese stock market’s reaction to sentiments regarding the Novel Coronavirus 2019 (COVID-19). Using 6.3 million items of textual data extracted from the official news media and Sina Weibo blogsite, we develop two COVID-19 sentiment indices that capture the moods related to COVID-19. Our sentiment indices are real-time and forward-looking indices in the stock market. We discover that stock returns and turnover rates were positively predicted by the COVID-19 sentiments during the period from December 17, 2019 to March 13, 2020. Consistent with this prediction, margin trading and short selling activities intensified proactively with growth sentiment. Overall, these results illustrate how the effects of the pandemic crisis were amplified by the sentiments.     

Impacts of COVID-19 outbreak,macroeconomic and financial stress factors on price spillovers among green bond

We examine the impacts of the COVID-19 pandemic and global risk factors on the upside and downside price spillovers of MSCI global, building, financial, industrial, and utility green bonds (GBs). Using copulas, CoVaR, and quantile regression approaches, we show symmetric tail dependence between MSCI global GB and both building and utility GBs. Moreover, the upper tail dependence between MSCI global GB and financial GB intensified during COVID-19. We find asymmetric risk spillovers from MSCI global GB to the remaining GBs. Finally, the COVID-19 spread, the Citi macro risk index, and the financial condition index contribute positively to the quantiles' risk spillovers. The spillover index method shows significant dynamic volatility spillovers from global GB to GB sectors that intensify during the pandemic outbreak, except for financial GB. The causality-in-mean and in-variance from COVID-19, Citi macro risk index, and US financial condition index to the downside and upside spillover effects are sensitive to quantiles     

Individual investor perceptions and behavior during the financial crisis

Combining monthly survey data with matching trading records, we examine how individual investor perceptions change and drive trading and risk-taking behavior during the 2008–2009 financial crisis. We find that investor perceptions fluctuate significantly during the crisis, with risk tolerance and risk perceptions being less volatile than return expectations. During the worst months of the crisis, investors’ return expectations and risk tolerance decrease, while their risk perceptions increase. Towards the end of the crisis, investor perceptions recover. We document substantial swings in trading and risk-taking behavior that are driven by changes in investor perceptions. Overall, individual investors continue to trade actively and do not de-risk their investment portfolios during the crisis.     

Internationalization and the capital structure of firms in emerging markets: Evidence from Latin America before and after the financial crisis

This study examines the impact of internationalization on the capital structure of firms in emerging markets before and after the financial crisis of 2008, with evidence from five countries in Latin America (Argentina, Brazil, Chile, Mexico, and Peru). We find that before the financial crisis, Latin American MNCs are characterized by lower debt levels than purely domestic firms. However, after the financial crisis, we find that the MNCs are characterized by higher debt levels. This finding suggests that after the financial crisis, the Latin American MNCs (like many firms) may be taking advantage of their access to low interest rates in the global capital markets.
