When can sustainable investing be counterproductive? Listen to Jason Mitchell discuss with Professor Kelly Shue, Yale University School of Management, why brown firms—not green firms—will drive the greatest emissions savings, how the cost of capital can be a powerful lever for behaviour change, and why it’s vital that sustainable investors move more towards energy transition-type strategies. Kelly Shue serves as a Professor of Finance at the Yale University School of Management. Her academic interests lie at the intersection of behavioural economics and empirical corporate finance. Her research has explored the Peter Principle, compensation and promotions, gender and negotiations, the gambler's fallacy, contrast effects and non-proportional thinking in asset pricing, and executive social networks. Her research has been featured in numerous news outlets including CNN, NPR, and the Wall Street Journal, and has been awarded the AQR Insight Award, the Wharton School-WRDS Award for Best Empirical Finance Paper, and the UBS Global Asset Management Award for Research in Investments. She serves as an associate editor at the Journal of Finance and Journal of Financial Economics, and previously served as an editor at the Review of Finance.  Her latest paper is Counterproductive Sustainable Investing: The Impact Elasticity of Brown and Green Firms
