  The effect of information disclosure procedures and policies on the cost of equity capital is one of the important issues which always is considered by regulators, entities and financial and accounting researchers. This relation is affected by various contextual characteristics (e.g. ownership structures, legislating system, economy and so on). The aim of this research is to examine the effect of ownership dispersion on the relation between voluntary disclosure and cost of equity capital. In doing so, the number of 610 firms of TSE listed Company were selected via systematic screening method. Data for variables were collected from several databases, such as CODAL, Central Bank, TSE-Client 2 software, and Statistical Centre of Iran. These data were analysed by the regressions model. The evidence shows that voluntary disclosure, ownership dispersion, and their interaction have significantly negative relations with the cost of equity capital. These findings indicate that an increase in voluntary disclosure and ownership dispersion causes a decrease in cost of equity capital. In addition, ownership structure intensifies the negative effect of voluntary disclosure on the cost of equity capital. Manuscript profile

  This research investigates the effect of Metacognition and cognitive failures on investors judgment and decision making, with the moderating role of voluntary disclosure. The present research was carried out using a test method based on a staged method of accounting and non-accounting information in the Google Forms software and 98 acceptable quiz of the investors were randomly selected and analyzed in 2017.

Metacognition and cognitive failures by mediating judgment have a significant effect on investors' decision making. With the moderating role of the voluntary disclosure, Metacognition and cognitive failures, there is a significant effect on investors judgment. With the moderating role of voluntary disclosure, Metacognition and cognitive failures through mediation of judgment, there is a significant effect on investors' decision making.

  AbstractThis paper investigates Impact of Voluntary Disclosure Level on Value Relevance ofAccounting Information, specifically, earnings and book values of Firms Listed in TehranStock Exchange (TSE). Based on the assumption that an increased focus on the informationalneeds of investors should increase the value relevance of the information contained infinancial statements, As a consequence, we expect that greater voluntary disclosure levelsamong companies listed on the TSE will be associated with greater value relevance inearnings and book value information for investors.

  The present study examines the effect of voluntary disclosure of historical and forward-looking non-financial information on sustainability performance and contributes to the existing literature by providing evidence of a definite relationship between the level of voluntary disclosure and sustainability performance in Iran. For content analysis, a checklist tool consisting of 23 components and 186 indicators was used to describe the disclosure criteria. In order to achieve the purpose of the research, the required data of 910 year-company observations (7 years and 130 companies) resulting from the screening process by systematic elimination of companies listed on the Tehran Stock Exchange, have been used in a descriptive-correlational manner from sources such as corporate board reports, financial statements, resource management software and new results with the implementation of content analysis test and multivariate linear regression model. The results showed that there is a positive and significant relationship between voluntary disclosure of non-financial information, historical and forward-looking non-financial information and sustainability performance. These findings indicate that the motivation of companies to disclose voluntary information, especially about the Iranian economy, is very important, because companies must grow economically and therefore their need for capital is high.

  Purpose: The present research aims to conduct meta-analysis of the effect of information disclosure on market reaction. In order to integrate the results of different researches and identify the determinants of relations between information disclosure and market reaction, we used meta-analysis methodology as a quantitative statistical method.Methodology: In order to implement the meta-analysis method, using software CMA from the website of foreign journals (published articles related to research variables from 1990 to 2020) and the website of domestic scientific research journals (published articles related to research variables from 1990 to 2020) to They were identified and collected as a statistical population of the research and finally 86 studies have been analyzed by systematic elimination method.Findings: The results of studies conducted in the mentioned period and around this relationship, using I2 and Q tests indicate that most of these studies are heterogeneous. In order to identify the cause of this heterogeneity, by dividing the research based on different criteria for measuring information disclosure and market reaction and calculating statistics within the group, we found that these different measurement criteria used in research is one of the contradictory factors in research results. In the following study, it was observed that there is no significant relationship between audit components and market reaction, while in contrast, between the types of voluntary and mandatory disclosure, and corporate governance components with market reaction, a significant relationship was observed.Originality / Value: Based on the findings of the present research, financial market activists and investors should pay more serious attention to the way of information disclosure and mandatory disclosure tools and composition of shareholders in their analysis, but audit components are a special guide for choosing the best capital option. It does not offer financial market participants. Manuscript profile
