This paper investigates the role of corporate financial reports in the Environmental Protection Agency's (EPA) regulatory activities. By tracking the EPA's direct retrieval of SEC filings, we identify three key findings. First, the EPA retrieves a large volume of financial reports, especially from firms in high‐pollution industries. Second, the EPA is more likely to access financial reports during enforcement investigations and significant rule proposals, but less so during compliance monitoring, with patterns varying predictably across firms. Third, the EPA's reliance on financial reports is potentially driven by its demand for information on firm liquidity, solvency, and profitability. Overall, our study highlights the usefulness of financial reports for the EPA as an environmental regulator.

This paper examines the effect of the mandatory adoption of International Financial Reporting Standards (IFRS) by the European Union on financial analysts’ information environment. To control for the effect of confounding concurrent events, we use a control sample of firms that had already voluntarily adopted IFRS at least two years prior to the mandatory adoption date. We find that analysts’ absolute forecast errors and forecast dispersion decrease relative to this control sample only for those mandatory IFRS adopters domiciled in countries with both strong enforcement regimes and domestic accounting standards that differ significantly from IFRS. Furthermore, for mandatory adopters domiciled in countries with both weak enforcement regimes and domestic accounting standards that differ significantly from IFRS, we find that forecast errors and dispersion decrease more for firms with stronger incentives for transparent financial reporting. These results highlight the important roles of enforcement regimes and firm‐level reporting incentives in determining the impact of mandatory IFRS adoption.
