We examine the causal effects of corporate governance on earnings management using shareholder‐sponsored proposals that pass or fail by a small margin of votes in annual shareholder meetings. This setting provides a causal estimate that overcomes concerns of endogeneity. Specifically, compared with firms whose shareholder proposals fall just short of a majority threshold, firms whose shareholder proposals narrowly pass have similar characteristics but a discretely higher likelihood of implementing improvements in governance. As such, we expect that firms whose shareholder proposals pass the threshold by a small margin exhibit a significantly lower level of earnings management. Employing a regression discontinuity design, we find results that support our expectation based on the propensity to just meet or beat analysts' forecasts by one cent as a proxy for earnings management. In addition, we show that the results are driven by governance changes that increase directors' monitoring. Our results are robust to using discretionary accruals as an alternative measure of earnings management. Collectively, the results suggest that improvements in corporate governance curtail earnings management, and support the underlying premise of regulators that improvements in corporate governance would improve financial reporting.

Boards of directors play their role in corporate governance by advising and/or monitoring managers. In the corporate disclosure literature, prior research has documented directors' monitoring role, yet empirical evidence on directors' advising role is limited. Since the advising role often entails information transfer, we examine directors who concurrently serve as directors or executives in the firms' related industries (DRIs) and hence possess valuable information about the firms' external operating environment. We hypothesize and find that more DRIs on boards are associated with more accurate management forecasts. This association is stronger when firms face greater uncertainty, and holds in settings where DRIs are unlikely to monitor managers, suggesting a distinct advising role of DRIs. Our study highlights directors' role as information suppliers and advisors who help shape corporate voluntary disclosure.

Since the Split Share Structure Reform took effect in China in 2005, holders of nontradable shares (controlling shareholders) have had to negotiate with holders of tradable shares (minority shareholders) to gain the liquidity right. In a typical deal reached, the controlling shareholder agrees to pay share compensation to minority shareholders and, in many cases, also pledges to meet a specific firm performance target (performance commitments). Using this reform setting, we examine the impact of performance commitments on earnings management behavior, and find the following results. First, less profitable firms have greater incentives to make performance commitments that help to reduce the share compensation that controlling shareholders have to pay. Second, firms entering into such commitments engage in earnings management to meet the promised performance target when actual performance falls short, and firms facing greater default costs tend to manage earnings more aggressively. Third, depending on the performance metric stipulated in the commitment contract, firms employ varying methods to manage earnings. We also find that firms that rely on earnings management to meet their performance targets display inferior performance in the postcommitment years relative to firms that do not. Overall, our evidence is consistent with performance commitment contracts (with costly defaults) between a firm's controlling and minority shareholders causing incentives for earnings management.
