Managers venture to voluntary disclosure to inform investors about firms’ future point of views, goals and strategies. Financial and non-financial voluntary information reduce information asymmetry, increase stock liquidity and improve financial stability. In this research the relation of voluntary disclosure level and information asymmetry of listed companies of Tehran Stock Exchange is investigated. Botosan (1997) check list which has been adjusted by kashanipour and et al. (2009) was utilized to measure voluntary disclosure level. The check list consists of 71 indices through six section of background information, the summery of historical results, Key Non-Financial Statistics, Segments Information, Projected Information and Management Discussion and Analysis. Moreover, information asymmetry variable is measured by using Venkatash and Chiang (1986) model. To test research hypotheses multivariate regression with panel data is utilized. The results show that there is no significant relation between voluntary disclosure level and information asymmetry of 122 listed companies of Tehran Stock Exchange during 2003-2011. Keywords: Voluntary disclosure level, Information asymmetry, Liquidity, Capital market.

In this research effect of extreme and moderate cash flows in explanatory power of model when the earnings are extreme is investigated through the extended version of Easton and Harris model. In this study in period of 1385 to 1391 we had 665 firm-year observations that after the removal of outliers we reach to 594 observations. We use OLS regression that in this regression we confront with unbalanced panel data with random effect. For classification of earnings and cash flows to extreme and moderate we use quintiles. Likewise, for comparing explanatory power of the models we use Cramer's (1987) Z-statistic. After all, with attention to statistic of this test we conclude that moderate cash flows relative to extreme cash flows when the earnings are extreme have effectson explanatory power.

The aim of this research is to investigate the effect of the earnings quality on improving the stock liquidity of listed companies in TSE. In this study, the earnings quality based on earnings stability, and two transactional criteria (the trading days and the ratio trading volume) and two informational criteria (the ratio depth and ratio spread) used to measure of the stock liquidity. To conduct this research, 94 listed companies in TSE during 2002-2011 via panel regression models (fixed effects) were investigated.
Findings indicate that there are not significant relationships between the earnings quality and different criteria of the stock liquidity.
