We explore revealed preferences for the contractual treatment of changes to GAAP in a large sample of private credit agreements issued by publicly held U.S. firms. We document a significant time‐trend toward excluding GAAP changes from the determination of covenant compliance over the period from 1994 to 2012. This trend is positively associated with proxies for standard setters’ shift in focus toward relevance and international accounting harmonization. At the firm level, borrowers facing higher uncertainty are more likely to write contracts that include GAAP changes, but these firms also show a more pronounced time‐trend toward excluding GAAP changes. While this evidence is broadly consistent with an efficiency role for GAAP changes in debt contracting, it is also consistent with a shift in standard setters’ focus offering a partial explanation of why fewer contracts rely on GAAP changes in 2012 than in 1994.

We examine the real effects of mandatory social-responsibility disclosures, which require SEC-registered mine owners to include their mine-safety records in their financial reports. These safety records are already publicly available elsewhere, which allows us to isolate and estimate the incremental real effects of including this information in financial reports. Comparing mines owned by SEC-registered issuers with mines that are not, we document that including safety records in financial reports decreases mining-related citations and injuries, and reduces labor productivity. Evidence from stock-market reactions and mutual-fund holdings suggests that increased awareness of safety issues is a likely explanation for the observed real effects.

The paper examines whether international regulatory harmonization increases cross-border labor migration. To study this question, we analyze European Union initiatives that harmonized accounting and auditing standards. Regulatory harmonization should reduce economic mobility barriers, essentially making it easier for accounting professionals to move across countries. Our research design compares the cross-border migration of accounting professionals relative to tightly matched other professionals before and after regulatory harmonization. We find that international labor migration in the accounting profession increases significantly relative to other professions. We provide evidence that this effect is due to harmonization, rather than increases in the demand for accounting services during the implementation of the rule changes. The findings illustrate that diversity in rules constitutes an economic barrier to cross-border labor mobility and, more specifically, that accounting harmonization can have a meaningful effect on cross-border migration.
