We provide an economics-based review of the pros and cons of ESG disclosures, emphasizing environmental disclosures from an investor-centric perspective. Our survey intends to guide corporate management and regulators in navigating the ESG disclosure terrain. Rather than summarizing the vast and growing ESG literature, we assess the economic arguments for ESG disclosure regulation and the form of this disclosure. We discuss investors’ demand for ESG information and its supply by publicly traded firms. We analyze the case for and against mandatory ESG disclosure. Finally, we weigh the efficiency of disclosure requirement characteristics, assuming mandatory ESG disclosure is warranted. We intend to be positive rather than prescriptive, providing a line of reasoning readers can employ to reach their own conclusions about what we ought to do.

This study examines the usefulness of an analyst-based valuation model in predicting cross-sectional stock returns. We estimate firms' fundamental values (V) using I/B/E/S consensus forecasts and a residual income model. We find that V is highly correlated with contemporaneous stock price, and that the V/P ratio is a good predictor of long-term cross-sectional returns. This effect is not explained by a firm's market beta, B/P ratio, or total market capitalization. In addition, we find errors in consensus analyst earnings forecasts are predictable, and that the predictive power of V/P can be improved by incorporating these errors.

We examine the relation between bank holdings of mortgage-backed securities (MBS) and MBS prices. Theory suggests feedback between MBS holdings and underlying asset markets can be aggravated by mark-to-market accounting. We measure feedback by the relation between asset returns and the changes in bank MBS holdings. Consistent with the existence of feedback effects related to mark-to-market, we find that for banks with high MBS, more nonperforming loans, and lower total capital ratio, changes in bank MBS positions are positively associated with changes in MBS prices and that this relation is reduced after the April 2009 mark-to-market rule clarification. To assess the effect of feedback on shareholder value, we test whether the stock-price response of banks to the announcement of the mark-to-market accounting rule clarification is associated with the intensity of feedback behavior. We find that the stock market reaction to the rule change is more positive for banks with more MBS, higher nonperforming loans and higher pre-rule-change feedback. We also find positive bond-price reactions to the rule change. Overall, our results suggest feedback related to mark-to-market accounting had a measurable effect on shareholder value.

Research documents price co‐movements, or “spillovers,” between focal firms and their peers at focal firms’ earnings announcements. We find that both signed and absolute co‐movements between focal‐ and peer‐firm returns are significantly lower at earnings‐announcement dates compared to other dates. Analytically, we demonstrate that co‐movements do not necessarily indicate common information; instead, co‐movements measure the relative proportion of focal firm‐specific information to common information in focal‐firm earnings announcements. We study three settings where information transfers might be higher: when focal firms report significant earnings surprises, are industry leaders, or share correlated earnings patterns with peer firms. We continue to find lower return correlations during focal‐firm earnings announcements. We conduct two alternative tests but fail to find evidence that common information released during focal‐firm earnings announcements is significantly greater than on other days. These results raise doubt about the extent of the information externality attributable to financial‐report releases.
