We show how external credit market development can affect corporate social responsibility. Using a sample of US public firms over the period 1991–2010, we find that bank deregulation negatively affects CSR performance. We argue that deregulation-induced banking competition enhances credit accessibility, thereby reducing firms’ incentives to pursue CSR as a means of securing stakeholder rewards. Empirical evidence shows that firms increase their use of debt financing in response to the intensified banking competition, and these firms experience a more pronounced decline in CSR performance. We alleviate the potential concern that the observed decline in CSR could be attributed to changes in bank monitoring following deregulation. Further analyses find that firms reduce CSR regardless of their material nature, suggesting that the primary driver of CSR could be the trade-off between costs and returns. Overall, our findings shed light on the strategic motives of CSR, which exhibits adaptability in response to business dynamism.

We investigate how external credit market development affects corporate earnings management, by studying the impact of the U.S. interstate banking and branching deregulations on the intensity of accruals-based and real earnings management. We find that the banking and branching deregulations significantly decrease both accruals-based and real earnings-management intensity among firms in deregulated states. The effect is stronger for those deregulated states that have lower bank branch density before deregulation and states that have greater out-of-state bank entry after deregulation. The impact on corporate earnings management is channelled through increased banking competition and credit supply providing firms with easier access to external financing. The findings are robust to various endogeneity concerns. We further document that interstate banking and branching deregulations reduce the instances of financial results being subsequently affected by accounting restatements and improve firms’ information environment.

We investigate whether and how the uniqueness of banking activities affects the performance and systemic risk of U.S. banks. We find that banks performing more unique activities exhibit higher profitability and lower risk, controlling for size, diversification, and other key characteristics. We further find that banks’ sensitivity to systemic risk displays an inversely U-shaped relation with activity uniqueness. We interpret the impact of uniqueness in analogy to recent theories showing that systemic diversity promotes financial stability. Our study highlights the role of uniqueness in banking and has important implications for policy makers and banking regulators.

We find that multi-bank holding companies (MBHCs) in the U.S. have lower insolvency risk than single-bank holding companies (SBHCs) at the parent level, but have significantly higher insolvency risk than the latter at the subsidiary level. Our results suggest that MBHC parents tend to benefit from the internal capital market while allowing for more risk-taking at the individual levels. We further find that the higher risk for MBHC affiliates is because of the organizational and geographic complexity at the MBHC parent level. Our results highlight the importance of government regulation on banks at both parent and subsidiary levels.

U.S. and Japanese firms dominate global convertible bond issuance. Previous research documents more favorable convertible bond announcement effects in Japan than in the U.S. and other developed countries. Using a global sample of convertible bonds issued from 1982 to 2012, we find that the more favorable announcement effects of Japanese convertibles are driven by their stated uses of proceeds. Japanese convertibles more often include capital expenditure as an intended use, while U.S. firms tend to mention general purposes to motivate their offering. Our findings illustrate the value to firms of being more explicit when disclosing the intended use of proceeds of security offerings.

We study the impact of the recent government bailout, called Trouble Asset Relief Program (TARP), on bank accounting quality. By adopting a difference-in-difference (DID) method, we find a significantly positive impact of TARP on earnings management of recipient banks, compared with their non-recipient peers. Further, we observe that TARP-recipient banks engage more in earnings-decreasing manipulation rather than earnings-increasing manipulation. This behavior is more obvious for those banks that voluntarily request for TARP funds. Also, participant banks change their accounting strategy to manipulate earnings upwards after TARP funds are paid back. Our findings confirm our hypothesis that TARP-recipient banks are motivated to manipulate downwards (or hide some earnings) to obtain further favorable treatment by the program administrators.

We examine the effects of bank’s political connection on bank performance and risk in China. We use hand-collected information on CEOs’ professional background to identify their political affiliations, and find that banks whose CEOs have former government experiences have higher return on assets, lower default risk, and lower credit risk. Additionally, politically connected banks have disproportionally higher performance when the CEOs previous worked in the same city where the current bank’s headquarter locates, had past banking experiences, spend more on entertainment and travel costs, and have higher previous administrative rankings (e.g., at the provincial or state level). These results suggest that politically connected banks have better access to lending to politically connected firms, which are high yield assets and more likely to be bailed out when in distress. Our results offer a mechanism of political rent seeking, consistent with the institutional environment of China’s banking and political system.

We examine the impact of competition on bank earnings persistence by exploiting a natural experiment following interstate banking deregulation that increased bank competition. We find that bank earnings adjustment speed increases after their states implement the deregulation. This relationship is weakened, however, with the increase of bank's abilities to sustain earnings, as reflected in size, diversification, managerial efficiency and safety. We further find that the impact of compeititon on bank earnings adjustment speed is direct but not indirectly through the channel of earnings management.

Using a unique proprietary dataset of daily mutual fund trading records and the COVID-19 pandemic-triggered lockdown in Wuhan (China) as a natural experiment, we find that individual mutual fund investors in Wuhan significantly reduced their daily trading frequency, total investment of their portfolios, and risk level of their invested funds during the lockdown period as compared to investors in other cities. The results suggest that the elimination of face-to-face interaction among individual investors during the lockdown reduced their information sharing, which led to more conservatism in their financial trading. We rule out alternative explanations of salience bias due to limited investor attention and temporary changes in personal circumstances such as depression and/or income reduction, during the lockdown period. Finally, consistent with the theory of naïve investor trading, we also find that investors received higher trading returns during the lockdown as they reduced trading aggressively in the absence of face-to-face interactions.
