This study attempts to find a proper answer to the question of why some firms disclose less than other firms do; although, the disclosure information is important for users of information? Alternatively, why different companies, disclose in different levels of information? For this end, using the panel data analysis the impact of firm's characteristics (size, tangibility, leverage, profitability and growth in profitability) are investigated on different disclosure levels for 128 listed companies in Tehran Stock Exchange during 2003- 2009 periods. Our findings imply that, the tangibility, leverage, and profitability affect the disclosure level; however, the size and growth opportunity have an insignificant effect on disclosure. This might be due to the difference in nature of the mandatory and voluntary disclosure. All companies regardless to their situation in the market are forced to disclose their information. Therefore, the accomplished analyses through mandatory and voluntary disclosure level have been also analyzed and compared. The results show that firm's characteristics affect the voluntary section of total disclosure only.

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.
