Insider Trading Restrictions and Insiders' Supply of Information: Evidence from Earnings Smoothing
Contemporary Accounting Research, 35 (2), 898–929 (2018)
Ivy Zhang, University of Minnesota

The authors 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, the authors 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, the authors’ evidence highlights the importance of country- and firm-level governance structures in determining the consequences of insider trading restrictions. The findings of this paper have important implications for insider trading regulations.

Cleansing My Abuse: A Reparative Response Model of Perpetrating Abusive Supervisor Behavior

Many of us have had a bad workplace interaction with a boss – for example, being yelled at or sworn at in front of others, receiving no credit for work that required serious effort or extra hours, or being humiliated for a past mistake. But have you thought how your boss might have felt after mistreating you? Did you notice a change in his or her behavior? It is common to assume that the boss would simply pretend that nothing happened or would even quietly blame the employee for the outburst. However, in a set of studies published in the Journal of Applied Psychology, the authors found that this is not necessarily true – some leaders actually feel bad and try to make amends.

Drawing from the literature on moral cleansing and moral courage, the authors posit that supervisors who engage in abusive behavior may paradoxically engage in more positive leadership behaviors subsequently as a result of feeling guilty. In addition, leader moral courage strengthens these effects by 1) amplifying the intensity of experienced guilt after perpetrating abusive supervisor behaviors, and 2) increasing the likelihood to perform reparative actions after experiencing feelings of guilt. Their research contributes to the theoretical understanding of leaders' responses toward their own abusive supervisor behavior and provides insights into how and when destructive leadership behaviors may, paradoxically, trigger more constructive behaviors.
