We empirically examine the effects of economic policy uncertainty (EPU) on earnings management in Japan. We find that EPU is negatively associated with earnings management, indicating that managers have incentive to reduce earnings management when EPU increases. We then examine the monitoring roles of various entities, focusing on the main bank that holds equity in their client firm. We find that the relationship between EPU and earnings management is less pronounced for firms with a main bank. The result is consistent with the view that the main bank’s monitoring role works well in normal times, resulting in less room for management to improve earnings quality when EPU is high. We find a similar result when considering firms with and without analyst coverage. These results suggest a moderating role of main banks and analysts in the relationship between EPU and earnings management. Finally, we find that the effect of EPU differs depending on subcategories on policy uncertainty and the extent of each firm’s exposure to that type of uncertainty

We investigate how external credit market development affects corporate earnings management, by studying the impact of the U.S. interstate banking and branching deregulations on the intensity of accruals-based and real earnings management. We find that the banking and branching deregulations significantly decrease both accruals-based and real earnings-management intensity among firms in deregulated states. The effect is stronger for those deregulated states that have lower bank branch density before deregulation and states that have greater out-of-state bank entry after deregulation. The impact on corporate earnings management is channelled through increased banking competition and credit supply providing firms with easier access to external financing. The findings are robust to various endogeneity concerns. We further document that interstate banking and branching deregulations reduce the instances of financial results being subsequently affected by accounting restatements and improve firms’ information environment

We study the impact of the recent government bailout, called Trouble Asset Relief Program (TARP), on bank accounting quality. By adopting a difference-in-difference (DID) method, we find a significantly positive impact of TARP on earnings management of recipient banks, compared with their non-recipient peers. Further, we observe that TARP-recipient banks engage more in earnings-decreasing manipulation rather than earnings-increasing manipulation. This behavior is more obvious for those banks that voluntarily request for TARP funds. Also, participant banks change their accounting strategy to manipulate earnings upwards after TARP funds are paid back. Our findings confirm our hypothesis that TARP-recipient banks are motivated to manipulate downwards (or hide some earnings) to obtain further favorable treatment by the program administrators

We examine the role of social media in firm acquisitions. Twitter utilizes the “push” technology that allows firms to reduce information asymmetry by disseminating news to a broader set of investors in a timely manner. Using hand collected acquisition announcements from Twitter covering the period from 2009 to 2012, we find that the acquirer size is a main determinant of disclosing acquisition announcements on Twitter. Large acquirers announce their acquisitions on Twitter and, as a result, are able to attenuate the anticipated negative market reaction at acquisition announcement. We find no evidence that the attenuation effect of announcing acquisitions on Twitter subsequently reverses or that announcing acquisitions on Twitter is positively associated with pre-announcement earnings management. Overall, our results suggest that Twitter has become an important investor relation channel for major corporate events such as acquisition announcements and that large acquirers can use this new channel to enhance stability in their stock prices
