This paper investigates the economic consequences of the Sarbanes–Oxley Act (SOX) by examining market reactions to related legislative events. Using concurrent stock returns of non-U.S.-traded foreign firms to estimate normal U.S. returns, I find that U.S. firms experienced a statistically significant negative cumulative abnormal return around key SOX events. I then examine the cross-sectional variation of U.S. firms’ returns around these events. Regression results are consistent with the non-audit services and governance provisions imposing net costs. Additional tests show that deferring the compliance of Section 404, which mandates an internal control test, resulted in significant cost savings for non-accelerated filers.

ABSTRACT We exploit the setting of first‐time enforcement of insider trading laws to investigate the relationship between insider trading opportunities and insiders’ supply of information. Insider trading opportunities motivate insiders to reduce their supply of information by concealing firm performance, thereby increasing their information advantage over outsiders, resulting in higher insider trading profits. Using data from 40 countries over the 1988–2004 period, we find that reporting opacity, as captured by earnings smoothness, decreases significantly after the initial enforcement of insider trading laws in countries with strong legal institutions. The decrease in earnings smoothness is positively related to the strictness of insider trading laws. The decrease in earnings smoothness is also more pronounced for countries that have more persistent insider trading law enforcement and for countries that impose more severe penalties on insider trading cases. Further analyses show that the decrease in earnings smoothness following insider trading enforcement is concentrated among firms that are not closely held and among high‐growth firms. In addition to uncovering a channel through which insider trading restrictions affect the information environment, our evidence highlights the importance of country‐ and firm‐level governance structures in determining the consequences of insider trading restrictions.

ABSTRACT We study whether mandatory adoption of International Financial Reporting Standards (IFRS) is associated with changes in the sensitivity of CEO turnover to accounting earnings and how the impact of IFRS adoption varies with country‐level institutions and firm‐level incentives. We find that CEO turnover responds more to a firm's accounting performance after adoption. This increase in turnover‐to‐earnings sensitivity is concentrated in countries with stronger enforcement of financial reporting and is more prominent for mandatory adopters that have strong firm‐level compliance incentives. In addition, we link the change in turnover‐to‐earnings sensitivity directly to accounting changes due to IFRS adoption and find a stronger adoption effect when firms report large overall accounting changes and large de‐recognition of loss provisions upon adoption. Some of the above findings are sensitive to the exclusion of UK firms, which account for more than half of our sample.

ABSTRACT This study investigates the impact of CEO compensation structure on post‐acquisition purchase price allocation, an accounting procedure that involves fair value estimation of various assets and liabilities. We find that CEOs whose compensation packages rely more on earnings‐based bonuses are more likely to overallocate the purchase price to goodwill, the largest asset recorded post‐acquisition. Because goodwill is not amortized, the overallocation likely increases post‐acquisition earnings and bonuses. We also find that, when the acquirer's CEO bonus plan includes performance measures that are not affected, or are less affected, by the overstatement of goodwill, such as cash flows, sales, or earnings growth, the overallocation to goodwill motivated by bonus plans diminishes.

ABSTRACT: A large body of research is devoted to understanding the causes and consequences of firms' adoption of internationally recognized accounting standards. Thus far, researchers' attention has focused almost exclusively on the informational benefits of the adoption. We extend the existing literature by offering a different, stewardship perspective. We hypothesize that the voluntary adoption of international accounting standards is associated with changes in the firm's internal performance evaluation process; in particular, it is associated with increases in the sensitivities of CEO turnover and employee layoffs to accounting earnings. Our results are consistent with these predictions.

A firm׳s investment in corporate social responsibility (CSR) builds a positive image of caring for social good and imposes additional costs on executives׳ informed trading, which is widely perceived self-serving. We thus expect executives of CSR-conscious firms to be more likely to refrain from informed trading. We find that executives of CSR-conscious firms profit significantly less from insider trades and are less likely to trade prior to future news than executives of non-CSR-conscious firms. The negative association between CSR and insider trading profits is more pronounced when executives׳ personal interests are more aligned with the interests of the firm.

During the past decade, new regulations have been adopted to improve audit committee effectiveness. Prior research has generally provided evidence in support of these regulations and suggests that a more independent and expert audit committee is more effective. We posit that CEO power reduces or even eliminates the improvements in audit committee effectiveness resulting from independent and financially expert committee members. Thus, CEO power may result in an audit committee that appears effective in form but is not in substance. We construct a composite index for CEO power by combining ten CEO characteristics and employ the incidence of internal control weaknesses as a proxy for audit committee monitoring quality. Since all the firms in our sample have completely independent audit committees, we use financial expertise to examine the impact of CEO power on audit committee effectiveness. We find that, when CEO power is low, audit committee financial expertise is negatively associated with the incidence of internal control weaknesses. However, as CEO power increases, this association monotonically weakens. When CEO power reaches a sufficiently high level, this association is no longer negative. The moderating effect of CEO power on audit committee effectiveness is more prominent when the CEO extracts more rents from the firm through insider trading. Our results are not driven by the CEO 's involvement in director selection. Our paper suggests that more expert audit committees in form do not automatically translate into more effective monitoring. Rather, the substantive monitoring effectiveness of audit committees is contingent on CEO power.
