In order to answer this question, In this study hypotheses regarding the impact of earnings management on the performance evaluation model based on Residual income and based on discounted cash flow in the two – year short term periods and seven –year long term periods were developed.
This study, which was performed by the correlation analysis, by using regression analysis and Means Comparison test, tries to provide the possibility of the optimal model selection for investors.
The population of this study is Companies listed on the Stock Exchange which has been active in the period of 1379-1390 years.
The results indicate that in the short-term horizon, earnings management hasn't a significant effect on the predictive ability of the listed evaluation models. But in the long-term time horizon Income smoothing has a significant effect on the evaluation models’forecast error, and in the long-term timescales Residual income model has Lower prediction error.
