Also, by changing the attitude of management in companies with low growth, the level of stock normal return has increased significantly, While abnormal returns on this correlation is not significant.

According to the Political Economy Theory, Economic and political structures can to affect managers, auditors and investors behavior in the face of the financial reporting.

Various factors affect the performance of banks. In this study, we try to investigate the relationship between corporate governance and affiliated companies and five management and financial areas with the performance of banks. This research is purposeful and descriptive-analytic in terms of the method. The data of this research are 6 years from 2008-2013. The statistical population consists of 12 banks and 72 affiliated and subordinate banks, information and data from The Tehran Stock Exchange System has been gathered. The research hypotheses were also tested using multivariate regression model. The results of the estimation of the research model indicate that there is a positive and significant relationship between corporate governance and the performance of banks, and there is a positive and significant relationship between affiliated companies and banks performance in terms of performance variables. That is, if performance of banks is measured by financial ratios, there is a positive and meaningful relationship and if the performance of banks is measured by balance sheet items, then there is not a significant relationship between them and in the case of management and financial areas, if performance is measured by financial ratios other than productivity management and liquidity ratio Other variables have a significant relationship with performance. And if performance is measured with balance sheet items, then there are significant relationships between five management and financial areas. Therefore, with the difference in performance variables, the relationship between the performance and the variables of the five management and financial areas, except the GDP, has changed.

The purpose of this paper is to examine The role of firm growth in stock return sensitivity to discretionary accruals in Tehran Stock Exchange. Given the rich growth opportunities and high information asymmetry in high-growth firms, we expect that managers have incentives to use discretionary accruals, especially income increasing (positive) discretionary accruals, to signal favorable private information to external investors. The study period is between the years 1389 to 1393 and the statistical sample of the study is 149 the companies listed in Tehran Stock Exchange (TSE). We use Panel-Data Regression and EGLS method to estimate the model parameters. This paper contains significant and consistent results. Our empirical tests reveal that overall there is no significant difference in the pricing of discretionary accruals between high-growth and low-growth firms. However, consistent with our expectations, we find in high-growth firms compared to low-growth firms, stock return is more sensitive to positive discretionary accruals than to total discretionary accruals.

Related Party Transactions are the information that users of financial statements are interested to know about that information. Hence, for better understanding and rational decision making by the users, to disclose information related to this type of transactions on the financial statements is necessary. Therefore, this study aims to investigate the effects of good and bad news on the relationship between related party transactions and capital markets reaction. According to the research done by Widari et al (2016), abnormal stock return is used as a measure of capital market reaction. In this regard, a sample of 92 listed companies of Tehran Stock Exchange were selected and studied in the period from 2009 to 2014. The results indicate that the related party transactions are positively associated with capital market reaction, but the good and bad news do not influence on the relationship disclosure of related party transactions and capital market reaction.

With the increase in the comparability of accounting information, managers face with more risks in implementing earnings management due to the possibility of exploring accrual-based earnings management by auditors and legal entities. Therefore, this method is expected to be used less, and instead accruals manipulation is replaced with real earnings management methods. Given the above argument, therefore, the current research aims to study the effect of comparability of financial statements on real-and accrual-based earnings management. The research hypotheses were developed and tested using a sample of 85 companies listed in Tehran Stock Exchange during the years 2012-2016 and Multivariate Regression Model based on panel data. The findings reveals that the comparability of accounting information reduces accrual-based earnings management, while increases real earnings management. In other words, with the increase in the comparability of financial statement, managers substitute real earnings management for accruals manipulation. In other words, with the increase in the comparability of financial statement, managers substitute real earnings management for accruals manipulation.

The aim of this study is to evaluate the direct and indirect corporate governance score and performance. in prior research, The role of information quality intervener in explaining the relationship between corporate governance and performance is not considered. In this regard, the present study seeks to explain the theoretical framework based on the quality of information intervener's variable, and this is a kind of contribution. For this purpose, the companies listed in Tehran Stock Exchange in the 1390-1394 times for 125 firms, intervals using a combination of generalized method of moment's estimators for dynamic panel models were used to. The relation is a direct correlation between corporate governance and performance in relation to corporate governance, an indirect relationship was established. The results indicate that a change in corporate governance leads to increased rates of 0.19 of the direct effect of the accounting practices of the 0.11 and 0.08, which an indirect effect. This reflects the impact of information quality on the relationship between corporate governance and performance.
