The aim of this study is to analyze the economic benefits of transparency or corporate disclosure. It is estimated the reduction of information asymmetry, which is a component of the cost of equity, due to the mandatory adoption of IFRS in Brazil, the level of commitment to corporate governance and the ADR issuance at the New York Stock Exchange. It uses the proxy bid-ask spread to estimate the asymmetry of information, as the dependent variable. The sample consists of non-financial companies of the Ibovespa index. In addition to disclosure variables, this study also analyzes the control variables like size, free float, risk and profitability. The conclusion of this dissertation confirms the initial expectations, in the sense that a higher corporate level of disclosure implies in a reduction of the asymmetry of information. Corporate governance variable, although significant, has a positive relationship with asymmetric information. This result is the opposite of what is expected by theory and can be subject of further studies. It is also statistically significant the expected positive relation between information asymmetry and the beta control variable.
