        In the current study, the information effect of liquidity on the dividend payouts was investigated in the companies listed on the Tehran Stock Exchang., that from the data on 102 companies for the years 2006-2015 were used and the model was estimated in Stata15 software by using panel logit (tobit) method. The study explores the relationships by using the moderating variables of information disclosure quality, free float and information asymmetry. Moreover, different liquidity measures (Amihud- Corwin and Schultz-the proportion of zeroreturns) were used to generalize the results for other cases.The results indicate that various liquidity factors have significant effects on profit sharing. When the liquidity index is the proportion of zero returns, the effect of moderating variables on the profit sharing is greater than the other variables. Moreover, according to the results of the moderating variables, when the float is the moderating variable, it leads to an increase in the liquidity index effect.According to the results, the liquidity and moderating variables have greater impacts on the cash dividend ranked by the cash flow from the operating activities (DVC) compared with that of the dependent variable of cash dividend ranked by earnings (DVE). It should be noted that the DVC, DVE, and liquidity variables were not endogenous. Therefore, it is confirmed that there is a one-way causality from liquidity towards DVC and DVE. Manuscript profile

        Previous research has shown that the high disclosure of corporate financial information can increase the efficiency of the investment. In addition, the mechanism of financial information disclosure and investment efficiency is a kind of reduction of information asymmetry that prevents investment efficiency. Unlike financial information, which is mainly about the past performance of companies, non-financial information, in particular forward-looking non-financial information (FNFI), is about the future development of the company, which can provide information that is more relevant for decision makers. Therefore, the FNFI can reduce information asymmetry between companies and external sources of funding. The purpose of this study was to investigate the effect of forward-looking non-financial information on corporate investment efficiency & financing constraint in listed companies on Tehran Stock Exchange. To this porpuse, a sample of 150 companies during 2010-2016 was selected by systematic elimination sampling. The research method is library and correlation. Forward-looking non-financial information the study consists of seven non-financial indicators and the relationship between research variables by the regression model presented by Tan and Liu (2017) with the pooled data approach have been used. The results show that forward-looking non-financial information can reduce financing constraints and high disclosure quality will intensify the relationship between these two variables. Forward-looking non-financial information can also reduce the inefficiency of investment, and the high disclosure quality will intensify the relationship between these two variables, then alleviate the underinvestment effectively and meanwhile leavelittle opportunity for overinvestment.

        The purpose of this study is to investigate the relationship between the auditor’s tenure and the quality of information disclosure. The sample of the research consists of 94 companies listed in the Tehran Stock Exchange during the years between 2004 to 2012. The results of theoretical research suggested that auditor’s tenure may influence on the quality of information disclosure through an effect on the auditing quality and independence. To measure the variable of disclosure quality, the advantages of each company are utilized. These advantages have been extracted by Tehran Stock Exchange Organization through notifications on the quality of information disclosure and proper informing. The aim of this study was to investigate the relationship between auditor tenure and disclosure quality with the use of multiple linear regression analysis and the separation of auditor tenure duration period into two short-term and long-term periods. The results indicated the existence of a significant and positive relationship between auditor’s tenure and disclosure quality. In other words, an increase in auditor’s tenure duration period will substantially lead to an increase in the disclosure quality.   Manuscript profile
