Governance through trading: does institutional trading discipline empire building and earnings management?

Accounting Session 1: Earnings ManagementThe Conference program's website is located at http://areas.kenan-flagler.unc.edu/conferences/2013cfea/Pages/Final%20Schedule.aspxThis paper empirically identifies an important external corporate governance mechanism through which the institutional trading improves firm values and disciplines managers from conducting value-destroying activities. We propose a reward-punishment intensity (RPI) measure, and show that it is positively related to firm’s subsequent Tobin’s Q. Importantly, we find that firms with higher RPI exhibit less subsequent empire building and earnings management. Furthermore, we show that the exogenous liquidity shock of Decimalization augments the governance effect of institutional trading. We also find that the discipline effect is more pronounced for firms with moderate institutional ownership concentration, higher managers’ wealth-performance sensitivity, and higher trading liquidity, which further supports the governance role of the RPI. The results are robust to using a subsample containing firms with reduced institutional ownership and to using two instrumental variables.postprin
