This study examines the effect of CEO overconfidence on accrual-based earnings management and real activities-based earnings management. Statistical population consists of 80 companies listed on the Tehran Stock Exchange during the period from 2010 to 2014. The variables used in this study are consisted of CEO overconfidence as the independent variable, and real earnings management and accrual-based earnings management as the dependent variables. Financial leverage, return on assets, profitability, and firm size are considered as the control variables. To measure the accrual-based earnings management, the discretionary accruals, and for measuring the real earnings management, the operating cash flow have been used. And to measure CEO overconfidence, the excess investment criteria have been used. In this study, a multivariate regression model using panel data (panel) was used to test the hypotheses. The results showed that there is a positive and significant relationship between real earnings management of listed companies in Tehran Stock Exchange and overconfidence management. But there is no any significant relationship between accrual-based earnings management and CEO overconfidence.
