In this study the effect of "Financial Leverage (FL) on Earning Response Coefficient (ERC)" for accepted members of Tehran Stock Exchange is considered. The purpose is to find out whether or not the investors, analysts, etc. consider the capital structure and leverages of the firms when reacting to the good and bad news caused by revealing the accounting in formation.
Financial Leverage measurement approaches are of two divisions as follows:
I) Income Statement
2) Balance sheet
In this research balance sheet approach i s used. In this approach, two definitions have been considered for leverage.
I) Debit/ assets Ratio
2) Debit I equity Ratio
Both definitions are used here. Studying the only research hypotheses using the regression analysis during 2000-20004 indicates that in the first leverage definition there is a reverse relationship between FL & ERC in the whole sample and in high leverage and in the second definition i n high leverage. However in the first definition in low leverage and i n the second one in the whole sample and in low leverage there's no considerable relationship between ERC and FL.

In the view or market theoreticians, investors and other participants, attain more successful with appropriate valuation measures. This article tries to show and compare the effect and relevance between various market indicators and stock price predictions.
For this purposes, market indicators have been categorized in three groups of: structural indicators, flow of fund indicators and sentiment indicators.
Single and multiple regression was used to test the research hypothesis and various market indicators. At last this paper concludes that the price variation can be predicted with indicators of I )firm size 2)earnings per share grouch 3)market breadth 4)free float rate and S)book value per share to price ratio. In other words, 53.5 % of stock price variations in Tehran stock exchange can be predicted with these four variables.

There are significant differences in disclosure of information among firms. Identification of factors affecting management in formation disclosure is a useful research area and wide variety of users such as: market pol icy makers, investors and academicians could take advantage of the results.
Earning forecast is important information that firms usually disclose. Corporate governance improves the performance of companies and their quality of disclosure.
This empirical research investigated the relationship between properties of management earning forecast, with two important corporate governance mechanism; outside directors and institutional investors.
Our sample is selected from listed companies in Tehran Stock Exchange (TSE) for a period of the years 2003 to 2005. The percentage of outside directors and firms aggregated common stock held by institutions are independent variables. Properties of management earnings forecasts are dependent variables. Forecast precision, forecast timeliness, forecast bias and the number of forecasts that is revised are proxies for those properties. The control variables are: size of the firm, the firm's auditor. the ratio of market to book value of the common equity, number of days between the forecast date and fiscal ending period date and good or bad news.
We established hypotheses based on the above variables and tested them by using single and Multiple Regression Analysis and Mann-Whitney U.
The result showed that; there is no significant relationship between two corporate governance mechanisms and proper ties of management earnings forecasts. The result as a whole doesn't discern any significant relationship between outside directors and in situational investors to precision, bias, timeliness of earning forecasts and revise on them.

This research seeks to find an answer to this quest ion ''how do some corporate governance practices affect earning management in Iran?"
The investigated corporate governance principals in this research are: the percentage of institutional investors' ownership, the existence of non-executive directors i n the board of directors, the absence (non-existence) of executive directors as the chief or ...... of board of directors, the existence or internal auditors.
In this research Jones modified model has been used to determine earning management which is measured by discretionary accruals. For this purpose, the data of l77 firms during the years 1382 to 1384 have been used. The results of this research show that when the percentage of institutional investors' ownership in firms is more than 45%,the earning management decreases.

The most investigation of earnings Management literature are about why and how earnings management are done and what the results of this behavior i s. But there have been very few researches on the ways to controlling this. This research pays attention to more and more complete disclosure as an approach for reducing earnings management.
In this research, disclosure quality is prepared and measured, using a check list containing 235 mandatory disclosure items (as Iranian accounting standards). Earnings management is also measured, using modified Jones Model, on discretionary accruals, and are finally used for testing the hypothesis. Hypothesis are tested as cross- sectional for the years 1382 to 1384 and accumulated.
The results in year to year investigations only for the year 1384 show statistically significant negative relationship between disclosure quality and earnings management. And in total of three years, investigations show no significant relationship.
