Firms' environmental behaviour depends mostly on how their revenues and costs are affected by consumers and investors' valuation of their specific sector and, at the same time, by the established regulatory framework and its enforcement. There is an empirical literature, which supports the impact of environmental information releases on stock prices, and finds larger effects in developing countries than in developed ones. We believe there is no strong reason why 'abnormal' returns should be higher due to environmental news in developing countries, which usually have weak regulatory institutions and low environmental consciousness. To illustrate our case, we perform an analysis of Argentina and we find similar results to those obtained in developed countries. Our calculations are robust to different estimation periods and models, and when subjected to parametric as well as non–parametric tests. We suggest more study is needed on the relationship between environmental news and the stock market in developing countries.
