%0 Journal Article %T Corporate Governance Index, Firm Valuation and Performance in Brazil %A Andr¨¦ Luiz Carvalhal da Silva %A Ricardo Pereira Camara Leal %J Revista Brasileira de Finan£¿as %D 2005 %I Brazilian Society of Finance %X This study investigates the relationship between the quality of a firms corporate governance practices and its valuation and performance, through the construction of a broad firm-specific corporate governance index for Brazilian listed companies. The empirical results indicate a high degree of ownership and control concentration. We can also note a significant difference between the voting and total capital owned by the largest shareholders, mainly through the existence of non-voting shares. Panel data results indicate that less than 4% of Brazilian firms have good corporate governance practices, and that firms with better corporate governance have significantly higher performance (return on assets). There is also positive relationship between Tobin¡¯s Q and better corporate governance practices although the results are not statistically significant. %K corporate governance index %K firm valuation and performance %K Brazil %U http://virtualbib.fgv.br/ojs/index.php/rbfin/article/view/1143
