This study collates potential economic effects of mandated disclosure and reporting standards for corporate social responsibility (CSR) and sustainability topics. We first outline key features of CSR reporting. Next, we draw on relevant academic literatures in accounting, finance, economics, and management to discuss and evaluate the potential economic consequences of a requirement for CSR and sustainability reporting for U.S. firms, including effects in capital markets, on stakeholders other than investors, and on firm behavior. We also discuss issues related to the implementation and enforcement of CSR and sustainability reporting standards as well as two approaches to sustainability reporting that differ in their overarching goals and materiality standards. Our analysis yields a number of insights that are relevant for the current debate on mandatory CSR and sustainability reporting. It also points scholars to avenues for future research.

We examine whether earnings reconciliation from U.K. generally accepted accounting principles (GAAP) to International Financial Reporting Standards (IFRS) convey information. As a result of debt contracting, mandatory accounting changes are expected to affect the likelihood of violating existing covenants based on rolling GAAP, leading to a redistribution of wealth between shareholders and lenders. Consistent with this prediction, we find significant market reactions to IFRS reconciliation announcements. These market reactions are more pronounced among firms that face a greater likelihood and costs of covenant violation and early announcements. While the association between later announcements and weaker market reactions is consistent with contractual implications of technical changes to earnings, which investors quickly learn to predict, it is inconsistent with IFRS forcing all firms in the sample to reveal firm‐specific information through accruals. Thus, by showing that mandatory IFRS also affects debt contracting, we expand on existing IFRS research that focuses on how accounting quality and cost of capital are impacted.

We examine the capital-market effects of changes in securities regulation in the European Union aimed at reducing market abuse and increasing transparency. To estimate causal effects for the population of E.U. firms, we exploit that for plausibly exogenous reasons, such as national legislative procedures, E.U. countries adopted these directives at different times. We find significant increases in market liquidity, but the effects are stronger in countries with stricter implementation and traditionally more stringent securities regulation. The findings suggest that countries with initially weaker regulation do not catch up with stronger countries, and that countries diverge more upon harmonizing regulation. (
