其他摘要：This paper examines the effect environmental management certification (ISO 14001) has on publicly traded Brazilian companies profitability. Signaling theory predicts that the certification serves to signal to society good environmental behavior; allowing people to screen the different types of firms, improving the financialeconomic performance of those firms that engage in this behavior. We performed difference-in-difference fixed effect design comparing the financial performance of companies with and without certification of their environmental management systems, using data on 552 companies over the period from 1996 to 2008. The results indicate that firms with an environmental management system certified according to the NBR ISO 14001:2004 standard tended to be more profitable, on average, than firms without certification.
