The corporate markets have been seen as a sector of the economy focused almost exclusively on the return to the shareholders, while ignoring its influence in the business and social environment in which it operates. Some observers even assumed that ethical business attitudes were incompatible with shareholder wealth maximization. Nonetheless, the market attitude towards unethical company practices has been changing, and companies have begun to adopt forms of responsible management practice and corporate governance without having to sacrifice their profitability. In this work we provide a review of the literature in corporate governance and economic sustainability in the world markets in general and in the Brazilian markets in particular. Finally, we present success cases of Brazilian companies through a research of the Brazilian market.
