This study examines the presence of real activities manipulation (REM) of IPO firms utilizing the cross-sectional regressions on each industry-year (Roychowdhury, 2006). The real activities examined in this paper include sales manipulation, reduction of discretionary expenses and overproduction. We show that IPO firms have significantly negative abnormal cash flows from operations and significantly positive abnormal production costs in the IPO year. The findings suggest that IPO firms not only manipulate accruals to inflate reported earnings, but also engage in real activities manipulation. We also show that IPO firms. decisions to manipulate earnings in the IPO year is positively related to the amounts of IPO proceeds and negatively related to the underwriters. reputation rankings and the presence of venture capital.
