Do Insiders Manipulate Earnings When They Sell Their Shares in an Initial Public Offering?
研究IPO中内部人出售股票是否影响研发支出，发现经理人出售股票时减少研发支出并增加应计项目操纵，以提升当期盈余。
ABSTRACT In this article we examine whether insider share selling in an initial public offering (IPO) influences R&D expenditures. Insiders (managers and venture capitalists) who sell their pre‐offering shareholdings might try to increase the IPO offer price (1) by overinvesting in R&D to signal the firm's prospects (the signaling hypothesis) or (2) by underinvesting in R&D to increase current reported earnings (the earnings fixation hypothesis). We find that, for a sample of 243 IPOs from 1986 to 1990, change in R&D spending in the year of the IPO is negatively related to managerial selling. Because reductions in R&D spending increase current earnings at the expense of future earnings, our evidence suggests that managers believe that investors place more emphasis on current earnings and less emphasis on R&D and therefore spend less on R&D. We also document a positive association between discretionary current accruals in the offering year and managerial selling, suggesting that selling managers manipulate accruals as well.
