This paper examines the effect of Environmental-, Social- and Governance- (ESG) rating events on returns and risks of stocks based on a large sample of US firms and their MSCI ESG ratings. Using event study methodology, we find that markets react with significant negative abnormal returns to...

We propose a simple measure of investor sophistication based on financial statement experience derived from publicly available EDGAR log data about accounting information acquisition activity. This approach allows us to provide unique empirical evidence for the existence of attention induced...

We analyze the interaction between high workload of the Securities and Exchange Commission (SEC) staff and the information production stimulated by their review process of initial public offerings (IPOs). We find that high workload is associated with more generic comments in the first letter,...

We examine the association between margin requirements and the market’s efficiency in incorporating firm-specific and market-level public news. Combining the Fed’s 22 changes in margin requirements with a hand-collected sample of earnings announcements between 1934-1975, we show that higher...

Therefore, researchers have devoted a lot of time in revealing the underlying factors that drive stock price synchronicity. Using a sample of...

The current study investigates the usage of virtuous language in the management discussion and analysis (MD&A) section of SEC filings (10-K Form) and the prognostic power of such language for takeover performance. The sample under study, obtained from Bloomberg, is comprised of a large number of...
