Within the UK's proactive financial-reporting enforcement regime, we examine the effect of increased regulatory scrutiny on equity values. We find that a fourfold increase in the likelihood of regulator-initiated reviews of financial reports reduces equity values by 1.3% on average. Reductions in equity values are largest for firms with strong private oversight that likely ensures that they are closer to their equity-value-maximizing level of transparency. Additional evidence suggests that competition increases and that managers' investment horizons decrease in industries selected for increased regulatory scrutiny, consistent with direct compliance costs not fully explaining the reduction in equity values.

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 exploit two regulatory shocks to examine the informational effects of tightening preexisting mandatory disclosure rules. Canadian National Instrument 51‐101 in 2003 and the U.S. rule “Modernization of Oil and Gas Reporting” in 2009 introduced quasi‐identical amendments which effectively tightened the rules governing oil and gas reserve disclosures in both countries. We document significant changes in firms' reporting outcomes when the new regulations are introduced. We also find that the reserve disclosures filed under the new regulations are more closely associated with stock price changes and with decreases in bid‐ask spreads. Our findings are robust to controlling for other confounding factors such as time trends, other information disclosed simultaneously, financial reporting incentives, mispricing, and monitoring efforts.

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. (

Corporations make substantial progress toward their Zero Routine Flaring commitments globally, particularly in Africa where preexisting environmental standards are weak. Moreover, committers’ flaring reductions on the continent are driven primarily by operational improvements rather than offloading assets and are concentrated among committers facing greater stakeholder pressure. Although flaring is higher for assets continuously operated by, awarded to, or divested to noncommitters, corporate actions to uphold commitments are associated with a conservatively estimated 10 percent net reduction in flaring in Africa without a corresponding reduction in oil production or local economic activity in extraction communities. Our findings suggest that environmental commitments are backed by corporate policies akin to establishing a uniform cost of pollution across the firm’s global operations and therefore may alleviate the problems posed by globally fragmented regulation.

We provide evidence that financial shocks to lenders influence the composition of financial covenants in debt contracts. Using two distinct measures of lender-specific shocks—defaults in a lender's corporate loan portfolio that occur outside the borrower's region and industry, and non-corporate loan delinquencies—we show that lenders respond to financial shocks by increasing the number and strictness of performance-based but not of capital-based covenants in debt contracts. We examine two possible channels for this result. We find evidence consistent with lenders using stricter control rights because of concerns about capital depletion (a capital channel) and because of new information about lenders' own screening ability (a learning channel). Our results indicate that lender preferences influence how accounting information is used in debt contracts.

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.

We show that a mid-2000s increase in extraterritorial enforcement of the U.S. Foreign Corrupt Practices Act (FCPA), characterized by greater international regulatory cooperation and more frequent use of the FCPA's accounting provisions, has a significant deterrent effect on foreign direct investment in high-corruption-risk countries. The decrease in investment is at least as large for non-U.S. as for U.S. firms, suggesting that widespread extraterritorial enforcement helps to create a level foreign investment playing field. Firms under U.S. jurisdiction with fundamental characteristics that make it more difficult to maintain effective internal controls invest less in high-corruption-risk countries after the FCPA enforcement increase, suggesting regulatory compliance costs play a role in deterring investment. Consistent with investments in accounting systems being one way, firms limit enforcement risk when investing in high-corruption-risk countries, firms pursuing new investments spend more time evaluating potential targets, and firms with existing investments report fewer restatements related to unintentional errors.

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.
