Conclusions
This paper had the Discretionary-based Disclosure (Verrecchia, 2001) as the
underpinning theory and aimed to indentify the factors that explain the level of voluntary
disclosure of Brazilian public companies. For these, we use a panel data approach, where the
level of voluntary disclosure (economic, social-environmental and total) has been explained
by 12 independent variables, which were the study’s hypotheses. Main findings are:
Sector and Origin of Control are statistically significant in all three models of
disclosure;
Profitability is statistically significant in the economic model and in the total model;
Tobin’s Q is statistically significant in the social and environment model and in the
total disclosure model;
Leverage and Auditing are statistically significant only in the economic model;
Size, Corporate Governance, Growth Opportunity are not statistically significant in
any of the models of disclosure;
Observed signals of angular coefficient are as expected from the existing literature,
except for growth opportunity that presented a negative relation with voluntary
disclosure.
Corporate Governance, Concentration of Control and Stock Issuing also presented
different signals. However, because they are binary variables and were not statistically
significant, further interpretation is not possible.
