摘要:Purpose – This paper evaluates the influence of the institutional environment on the extent of social and environmental disclosure of companies from institutionally distant countries. Design/methodology/approach – We analyze basic materials, oil and gas, and public utility companies with shares traded on the Brazilian stock exchange (BMFBovespa) and Canadian stock exchange (Toronto Stock Exchange) from 2007 to 2015. Quantitative methods are adopted through descriptive statistics and panel data analysis. The econometric modeling considers environmental and social disclosure as dependent variables, independent variables that represent the political, financial, educational and labor systems, and firm size, ROA, and indebtedness as control variables. Findings – In the case of the companies operating in Brazil, the extent of environmental and social disclosure is positively related to the political and labor systems, and negatively related to the financial system. In Canada, disclosure is negatively influenced by the financial system and the education system. The control variables, which represent characteristics of financial performance, were not significant. Originality/value – The study shows that isomorphic forces operate in the institutional field and affect the adoption of socially responsible behavior. By basing the study on institutionally distinct countries, such as Brazil and Canada, it reinforces the influence of the national business system on the extent of disclosure of environmental and social practices.
