Evidence for the Existence of Downward Real-Activity Earnings Management
研究发现在股票回购、管理层收购和CEO期权授予等事件前，管理者会通过向下真实活动盈余管理暂时压低市场估值，且该行为受激励和成本因素影响。
Prior studies of real-activity earnings management (REM) focus on earnings-inflating abnormal activities. We seek to establish the existence of downward REM by investigating several corporate events in which managers have incentives to temporarily deflate market valuations. Specifically, we focus on, and find downward REM before, share repurchases, management buyouts (MBOs), and CEO option awards. Large-sample evidence of downward REM is also found in our general analysis of earnings smoothing. Downward REM becomes much smaller or nonexistent when there is a lack of managerial incentives in those events, such as non-carry-through repurchases, incomplete MBOs, and unexpected option awards. Following the research design of Zang, we find that various REM and accrual-based earnings management (AEM) cost factors consistently influence the magnitude of downward REM and AEM around the three corporate events.
