The effect of corporate sustainability performance on leverage adjustments

We examine the impact of corporate sustainability performance (CSP) on the speed at which firms adjust their leverage ratios to the target levels for a large sample of 31 countries from 2002 to 2018. Using two proxies of CSP, we find that firms with superior CSP tend to adjust faster toward their target leverage ratios. In exploring the potential underlying economic mechanisms through which CSP affects leverage adjustments, we find that better CSP helps firms to ease information asymmetry, enhance stakeholder engagement, push up stock prices in the stock market, and improve competitive advantage in the product market. In the cross section, the positive association between CSP and leverage adjustment speed is less pronounced in countries with high-quality institutions. The results remain unchanged in robustness tests. Overall, this paper highlights the important role of CSP in shaping corporate capital structure dynamics and suggests implications for corporate strategic planning on the privately optimal levels of CSP activities.     

Do ADRs enhance portfolio performance for a domestic portfolio? Evidence from the 1990s

American depository receipts (ADRs) represent an increasingly popular and convenient mechanism for international investing. We analyze ADRs traded throughout the 1990s and find that these securities offer a diversification and portfolio performance benefit when combined with a domestic portfolio (proxied by the S&P 500). While we find that emerging market ADRs are effective instruments for reducing portfolio risk, they do not improve portfolio performance as measured by the Sharpe ratio. Developed market ADRs do improve portfolio performance as measured by the Sharpe ratio. The asset allocation which maximizes the Sharpe ratio is 84 percent domestic stocks, 16 percent developed ADRs, and 0 percent emerging ADRs. Further, due to problems in defining an appropriate market index for ADRs, the Sharpe ratio is viewed to be the preferred performance measure. Other measures such as Jensen’s alpha and the Treynor measure are susceptible to being “gamed” to distort portfolio performance.     

Do institutional shareholder services (ISS) corporate governance ratings reflect a company's operating performance?

Little is known about the relation between the actual governance rating received by a firm and the firm's performance. In this study, we examine the relation between the actual corporate governance rating received by a firm and the firm's performance during the years 2002–2004. We use the institutional shareholder services (ISS) corporate governance quotient (CGQ) rating of a firm's corporate governance structure and analyze this rating in relation to the firm's operating performance. We compare the institutional shareholder services’ CGQ rating to two measures of the firm's operating performance, return on assets (ROA) and return on equity (ROE). Based upon our results, we do not find statistical evidence suggesting that the firms’ operating performance is related to the firms’ ISS corporate governance rating.     

How much do firms hedge with derivatives?

For 234 large non-financial corporations using derivatives, we report the magnitude of their risk exposure hedged by financial derivatives. If interest rates, currency exchange rates, and commodity prices change simultaneously by three standard deviations, the median firm's derivatives portfolio, at most, generates $15 million in cash and $31 million in value. These amounts are modest relative to firm size, and operating and investing cash flows, and other benchmarks. Corporate derivatives use appears to be a small piece of non-financial firms’ overall risk profile. This suggests a need to rethink past empirical research documenting the importance of firms’ derivative use.     

Corporate governance and operating performance of Chinese listed firms

In this paper, we investigate the impact of corporate governance on firm performance and valuation in China. Our study introduces a composite measure of corporate governance to measure the association between corporate governance and Chinese firms’ performance and valuation. Because agency theory suggests that companies with better corporate governance standards perform better, we propose that better governed Chinese firms would have greater performance and higher valuation. We find that our composite measure of corporate governance is positively and significantly associated with firm performance and valuation. These findings have implications for policy makers, researchers, managers, and investors in general and those in emerging markets in particular.     

The stocks at stake: Return and risk in socially responsible investment

We relate US portfolio returns, book-to-market values and excess stock returns to different dimensions of socially responsible performance. We find that socially responsible investing (SRI) impacts on stock returns by lowering the book-to-market ratio and not by generating positive alphas. Our result is consistent with the theoretical work suggesting that SRI is reflected in demand differences between SRI and non-SRI stock. It also explains why so few studies are able to establish a link between alpha’s and SRI.     

Partner selection and governance design in interfirm relationships

This paper develops a structural model to simultaneously analyze firms’ partner selection activities and governance design for managing interfirm relationships. The model predicts these choices to be influenced by appropriation concerns, coordination requirements, dependence and prior experiences with the exchange partner. An analysis of 817 information technology transactions shows that appropriation concerns, coordination requirements and dependence influence governance design, while buyers’ partner selection effort relates mainly to appropriation concerns. Partner experience developed during prior ties with the exchange partner is found to moderate the effects of these control problems. In addition, partner selection and formal governance are found to be used as complements instead of substitutes in coping with interfirm control problems.     

Corporate social performance and financial risk: Further empirical evidence using higher frequency data

Using a unique dataset of corporate social responsibility rating – available on a monthly basis – we shed new light on the relationship between corporate social performance (CSP) and firm risk. Where previous studies use annual (at best) measures of CSP, assuming that a change in CSP leads a change in risk, we formally test the direction of the relationship using Granger causality. Looking at large UK companies over 2002–2018 (for a total number of 19,832 firm-months), we reject any causality (either way) between CSP and financial risk (both systematic and idiosyncratic risk). This shows that the CSP-risk relationship is not an endogenous one, contrary to what previous evidence has found. Given the structure of our panel data (long T and short N), we apply GLS based estimator to correct for serial correlation in our panel regressions. We find strong evidence that CSP has a negative impact on idiosyncratic risk; however, the effect of CSP on systematic risk is not statistically significant. The existence of a contemporaneous, rather than lagged relationship doesn't fare well with established CSP theories. Overall, our original approach has opened a new door to further the study of the link between CSP, financial performance and financial risk.     

CEO turnover in China: the role of market-based and accounting performance measures

We investigate the relationship between chief executive officer (CEO) turnover and firm performance in China's publicly traded firms. We provide evidence on the use of accounting and market-based performance measures in CEO turnover decision. We also investigate the moderating roles of noise in performance measures, firm growth opportunities, state-owned enterprises, and corporate governance reform on the weights attached to these performance measures. We observe that Chinese listed firms rely more on accounting performance than on stock market performance when determining CEO turnover. Firms with noisier performance measures and larger growth opportunities rely less on both accounting performance and stock market performance in CEO replacement decision. State-controlled firms are more likely to use accounting performance to determine CEO turnover. Finally, we observe that the weight attached to the accounting performance measure is significantly reduced and the weight attached to the stock market performance measure is significantly increased after the governance reform. We also observe that the reform has different impact on state-owned firms and private firms in terms of the sensitivity of CEO turnover to firm performance.     

On the stability of long-run relationships between emerging and US stock markets

While most studies have found no cointegration between emerging and US stock markets, some recent studies do find a long-run relationship exists between these markets. In view of these mixed findings, this study examines the stability of long-run relationships between a number of emerging stock markets and the US stock market using recursive cointegration analysis. The results show that no long-run relationship exists between emerging markets and the US market over most of the sample period throughout 1997. However, we do find clear evidence of cointegration in response to the recent global emerging market crisis in 1997–1998. We conclude that significant crisis events can change the degree of cointegration between international stock markets and, therefore, need to be taken into account in studies of long-run relationships between international stock markets.
