The main purpose of this study is to investigate the impact of corporate governance on the relationship between managerial ability and lack of information transparency in listed companies in Tehran Stock Exchange. Research hypotheses based on the 106 companies during a 9-year period from 2010 to 2018 were tested using multivariate regression models. Demerjian & et al. (2012) model was used to measure management ability and to calculate the corporate opacity, the criteria of the index rate of lack of transparency in company information and discretionary accrual items were used. The results show that there is a negative significant relationship between managerial ability and lack of transparency of company information. Also, the CEO duality has a negative impact on the relationship between managerial ability and lack of transparency of company information (in particular, discretionary accrual items). Finally, institutional shareholders have a negative effect on the relationship between managerial ability and lack of transparency of company information (the index rate of lack of transparency in company information and discretionary accrual items).

The main purpose of this article is to analyze the effects of the capital structure on the cumulative abnormal returns to reach such a goal we select information of 44 firms in the years 1376-1386. Multiple regressions (stepwise method) were used to test the hypothesis and their meaningfulness was reached by using t and F statistics. On the other hand, the Durbin-Watson test was applied to examine the autocorrelation of the model. The results showed that: Leverage doesn’t have a meaningful impact on the cumulative abnormal returns; Systematic risk, P/E ratio, BM ratio and the size of the firm would significantly affect the cumulative abnormal returns.
