This research examines the association between auditor industry specialization and real earnings management and its impact on future operating performance.This essay investigates whether clients of industry specialist auditors are constrained from managing earnings through accruals manipulation and, therefore, are more likely to engage in real activities manipulation and then examines whether operating performance declines for firms suspected of real activities manipulation For investigating this relationship; we use data for 115 listed companies on Tehran Stock Exchange for period of 2002-2007. In this study the absolute value of discretionary accruals is used as a proxy for accounting-based earnings management and a market approach as a proxy for determining of specialist industry auditor and sales manipulation, Reduction of discretionary expenditures & Overproduction for measuring real earnings management. ROA is used as a measure for operating performance,Findings indicate that clients of industry specialist auditors have lower absolute value of accruals relative to firms with incentives to manage earnings that do not hire industry specialist auditors. These clients of industry specialist auditors are also more likely to engage in real activities manipulation, suggesting this is a possible unintended consequence of hiring an industry specialist auditor. I also document evidence that firms suspected of real activities manipulation do not have lower future operating performance relative to firms not suspected of real activities manipulation.

This study investigates Ohlson's Linear Information Dynamic (LID) and evaluates the effect of "other information" on the abnormal earnings series using 100 firms panel data during 1376-1386 by Generalized Method of Moments(GMM). It tests the effect of industry structure, market share and capital intensity as "other informayion" on abnormal earnings of the following period, with Ohlson's LID persistence maintained. The results confirm the premise of LID, considering all the statistical models. The results also indicate that industry structure and capital intensity influence abnormal earnings persistence. Therefore, the industry structure and capital intensity have a informational content and reflect in Ohlson's Model (1995) as "other information". Confirm with the results the hypothesis that market share influences abnormal earnings persistence is rejected; Therefore, market share firm size does not have informational content and does not reflect in the Ohlson's Model(1995).
