Foram utilizados diversos indicadores para o desempenho como o ebit-to-sales, o market-tosales,o return on assets e o return on equity. Confirmou-se a hipótese inicial de que melhores níveis degovernança estão associados a melhores desempenhos das empresas. Os resultados conseguidos por meioda aplicação do método das regressões lineares foram confirmados pelos resultados obtidos com o uso dométodo das equações estruturais. Observou-se endogeneidade que não invalidou os resultados obtidos com ouso das regressões lineares. Encontraram-se evidências de relação de causalidade no sentido de governançapara os indicadores da variável de desempenho.
