Every Little Helps? ESG News and Stock Market Reaction, Gunther Capelle-Blancard, Aurélien Petit, Journal of Business Ethics, 18 September 2017
Stories about corporate social responsibility have become very frequent over the past decade, and managers can no longer ignore their impact on firm value. In this paper, we investigate the extent and the determinants of the stock market’s reaction following ordinary news related to environmental, social and governance issues—the so-called ESG factors. To that purpose, we use an original database provided by Covalence EthicalQuote. Our empirical analysis is based on about 33,000 ESG news (positive or negative), targeting one hundred listed companies over the period 2002–2010.
