This study examines the impact of corporate governance structure and free cash flow on over-investment on 121 firms listed in Tehran Stock Exchange over the period 2008-2011. To measure over-investment, free cash flow and corporate governance variables based on available information reported on financial statements are gathered and using cross section regression method, different hypotheses of the survey are examined. The results indicate that among corporate governance mechanisms investigated in survey, there is a significant relationship between percentage of non-executive directors and ownership concentration with over-investment. However, there was no meaningful relationship among controlling shareholders and duality with over-investment. Furthermore, a significant relationship between free cash flow and over-investment has been found.

The purpose of this paper is to examine the association between corporate governance and Intellectual capital in the pharmaceutical companies accepted in Tehran Stock Exchange over the period 2004-2009 using a regression based model.

This study analyzes the determinants of non audit-fees for a sample of 67 French companies belonging to the SBF 120 index during the period 2005-2007. Our attention focused on the influence of shareholder / creditor agency costs - namely debts and investment opportunities. Based on panel regression methodology, our results reveal that the affiliation of the auditor to an international network, the presence of an audit committee, the debt, the size of the company and the closing date have an effect on non-audit fees. However, investment opportunities do not affect the amount of non-audit fees.

Institutional investors play important role on formation of different changes on corporate governance systems. They can significantly influence on companies by monitoring the performance of management and limiting their opportunistic behaviors and manipulating their financial statements. Therefore, the main objective of the present study is to investigate the relationship between institutional investors and earnings management on some listed companies on Tehran Stock Exchange by examining a sample of 700 firm-years data over the period 2006-2010. In this study, the discretionary accruals are used as an indicator for earnings management. The results indicate that there is a positive and significant relationship between institutional investors and earnings management and suggest that increasing the ownership percentage of institutional shareholders increases earnings management. In addition, the results of the control variables have shown that firm size had no impact on earnings management, but financial leverage and return on sales, respectively had negative and positive effect on the earnings management of companies.

This paper investigates the impact of corporate governance on firm value measured by Tobin’s Q. Different corporate governance proxies i.e. board size, board independence, audit committee and CEO duality are interacted with firm value. A sample of 91 nonfinancial firms listed on KSE was selected over the period 2010-2014. The findings of the study show that board size and CEO duality had negative impacts on firm value. Moreover, board size, non-executive directors and audit committee had positive and significant impacts on firm value.

Moral hazard and corporate governance are important factors in determining market transparency. The proposed study of this paper investigates the effects of these two factors on earning quality as well as forecasted earning in Tehran Stock Exchange. We have selected some stocks based on some predefined circumstances and extracted some necessary information over the period of 2005-2010. Based on these criteria, the information of 132 firms are qualified for the proposed study of this paper using 792 years/firm from 23 industries. There are two hypotheses associated with this study. According to the first hypothesis, we investigate whether there is a relationship between board of director independency and quality of forecasted earning. In the second hypothesis, we look to find out whether there is a relationship between the size of board of directors and quality of forecasted earning. We have used three models and using ordinary regression analysis tried to test the models. Based on the results of the survey, we have concluded that moral hazard does not influence forecasted earning, significantly. However, the results of this survey concluded that there is a meaningful relationship between forecasted earning and quality of earning. In terms of members of editorial board, quality of earning has a reverse relationship with absolute deviation of forecasted earning. In other words, as the number of editorial board increases, we may expect a more precise earning estimation. The other observation is that non-board member & apos; s duties have better motivation to contribute to firms and could make some changes.

In this paper, we present an empirical study to find the relationship between discretionary accruals quality as well as innate accruals quality and portion of non-executive board of directors, concentration of ownership ratio and board size in Tehran Stock Exchange. The survey selects 118 qualified stocks from this exchange and using a random technique chooses 42 firms. The study implements two linear regression techniques to estimate the first part of the information and then using structural equation modeling examines six hypotheses. Based on the results of this survey we can conclude that an increase on non-executive members positively influences on discretionary accruals quality and negatively influences innate accruals quality. Concentration of ownership ratio positively influences on discretionary accruals quality and negatively impacts on innate accruals quality. Finally, size of board of directors negatively impacts discretionary accruals quality and positively influences on innate accruals quality.

In this paper, we study the effects of no-interest activities on return of some Iranian banks over the period of 2006-2011 using Pearson correlation as well as regression analysis. The paper uses two independent variables where the first one is obtained as a difference between other no-interest incomes with commission fee and the second one is the commission fee income. There are three dependent variables including return on investment, return of assets and risk, leading us to setup three regressions analysis. The result of our survey indicates that no-interest based activities have meaningful effects on the performances of banks. In addition, there are some meaningful relationships among interest free activities, which are mostly in terms of negative relations.

This paper investigates corporate governance and ownership effects on earning quality in Iranian private banks. The study uses the information of 12 private banks from year 2005 to 2010 using regression analysis based on panel data. Among different factors, the effect of big five shareholder are considered to be significant and positive on earning quality. In addition, the effect of one variable regression test reveals that institutional ownership has positive impact on earning quality. However, the impacts of other variables including percentage of ownership concentration, the size of board of directors, reliance on debt, logarithm of sum of assets, return of assets, logarithm of operating cash flow on earning quality are not meaningful. The result of this survey indicates that institutional ownership plays an important role earning quality simply because institutions normally have the access on professionals to control management.
