This paper examines the impact of twenty-three pronouncements related to fair value accounting (FVA) rules on equity prices of financial institutions. The results document that announcements that signal an increased (decreased) probability of issuance of FVA standards produce negative (positive) abnormal stock price reactions for sample banks. Further, the magnitude of the stock price reactions is negatively related to a bank's primary capital ratio and positively related to the ratio of the book value of the investment portfolio to total assets and the ratio of the difference between the market and book value of the investment portfolio to total assets.

This study examines the equity price reaction to the pronouncements related to accounting for stock-based compensation and assesses the value relevance of recognition versus disclosure in financial reporting. We document that firms exhibit significant abnormal returns around the issuance of the Exposure Drafts proposing to require recognition of stock-based compensation costs, and also around the event reversing that decision to require disclosure only (while encouraging recognition). We also document that the abnormal returns are most pronounced for high-tech, high-growth, and start-up firms. Our results are consistent with the contracting theory, and show that disclosure is not a substitute for recognition.

The Sarbanes‐Oxley Act of 2002 (“the Act”) was enacted in response to numerous corporate and accounting scandals. It aims to reinforce corporate accountability and professional responsibility in order to restore investor confidence in corporate America. This study examines the capital‐market reaction to the Act and finds a positive (negative) abnormal return at the time of several legislative events that increased (decreased) the likelihood of the passage of the Act. We interpret this finding as evidence supporting the notion that the Act is wealth‐increasing in the sense that its induced benefits significantly outweigh its imposed compliance costs. We also find that the market reaction is more positive for firms that are more compliant with the provisions of the Act prior to its enactment.

This paper investigates whether and how business sustainability performance and disclosure factors affect stock price informativeness (SPI). We find that non-financial environmental, social, and governance (ESG) sustainability performance factors are positively associated with idiosyncratic volatility (our proxy for SPI) after controlling for financial-economic performance. We further show that the association between sustainability performance factors and SPI is stronger for firms with higher sustainability disclosure. We find that the association between ESG sustainability performance factors and SPI is stronger when economic performance is weaker, suggesting that investors tend to pay more attention to ESG performance factors when firms are financially underperforming. This study shows that investors pay attention to both firm economic performance (corporate profitability and growth prospect) and ESG sustainability performance and disclosure factors, which have implications for policymakers, regulators, investors, businesses, and researchers.

Business sustainability has emerged as the theme of the 21st century. We examine whether and how different components of economic sustainability disclosure (ECON), as well as environmental, social, and governance (ESG) dimensions of sustainability performance affect cost of equity, individually and in aggregate. In addition, we investigate whether and how ECON and ESG sustainability interactively affect cost of equity capital. Costs of equity are calculated using industry adjusted earnings–price ratios and finite horizon expected return model. Using a sample of more than 3000 firms during 1990–2013, we find that ECON (ESG) is negatively associated with cost of equity, but only growth and research (environmental and governance) sustainability performance dimensions contribute to this relationship. Operation efficiency is positively, while social sustainability performance is only marginally, related to cost of equity. We also find that ECON and ESG sustainability performance interactively affect cost of equity. In general, the relationship between ECON (ESG) and cost of capital is strengthened when ESG (ECON) performance is strong.

Prior studies show that comment letters released by the Securities and Exchange Commission provide information on firms’ financial reporting quality and can have adverse value implications about the firms. We examine whether short sellers front-run comment letter disclosures and take short positions based on the economic implications of the letters. We find that short interest increases before comment letter disclosures and that the increase is positively associated with the severity of the letters. We also find evidence suggesting that short sellers obtain private information through social connections with corporate insiders. Finally, we document a negative but delayed market reaction to the disclosure of severe comment letters. These results suggest that front running the comment letter disclosure is not the optimal trading strategy for short sellers. Short sellers can gain similar profits, and bear less risk, if they put off increasing their short positions until after the disclosure.
