The inherent breadth and ambiguity of environmental, social and governance issues has resulted in the integration of ESG considerations into portfolio design remaining largely a philosophical push, without clarity on the direct and indirect impacts on shareholder value. In this working paper, AQR Capital Management’s Jeff Dunn, outlines a simple framework for considering the impact of ESG issues with respect to their role in investment decisions, with the aim of providing a clearer path for further investigation of the impact of ESG policies on shareholder value and how they can be appropriately included in the investment decisions of both investors and fiduciaries.
