Voluntary Disclosure

This study aimed to investigate the relationship between voluntary disclosure and earnings management and financial performance during the life cycle of the listed companies in Tehran Stock Exchange. The statistical population of the study included all listed companies in Tehran Stock Exchange since 2013-2018. In this study, earnings management, the financial performance of the companies (including return on equity, returns on assets, Tobin Q ratio, economic value-added, and refined economic value added) were the dependent variables, and the level of voluntary disclosure was the independent variable and the life cycle of the company was considered as the moderating variable. Also, in order to test the research hypotheses, a linear multivariate regression model using combined data was used. The results showed that earnings management and financial performance indicators have a significant relationship with voluntary disclosure over the life cycle. Accordingly, an increase in the level of voluntary disclosure increased the company's performance. Also, the results of the study indicated that the company's life cycle mediates the relationship between the level of voluntary disclosure and the company's performance.
