The aim of the present study is to model voluntary disclosure using quantitative averaging model in Tehran Stock Exchange. The period of this research is between 1391 to 1402. In the quantitative approach, research community includes listed companies which based on screening approach was 175 companies which have been experienced for modeling.
88 factors, which are effective on voluntary information disclosure of investors are examined in Dynamic, Bayesian, and selective averaging model. Based on the results, in all three time periods, time-varying averaging model had higher accuracy rather than other approach. In the short-term, 51 factors (27 internal factors and 24 external factors); In the medium term, 44 factors (26 internal factors and 18 external factors); and in the long-term, 54 factors (32 internal factors and 22 external factors) have been identified as the main influencing factors on voluntary information disclosure of investors. Based on the results, we have been separated internal and external factors. Principle-components analysis approach show internal factors have been more effective than external factors on disclosure changes. Finally, the coefficients were estimated in different time intervals using the TVP-FAVAR model. The results show that internal factors have positive effects on voluntary information disclosure in different time intervals, while the effects of external factors were generally negative.
