Abstract

This paper presents a generalized supply and demand framework for asset pricing in a production economy with externalities. The framework challenges conventional wisdom and produces a microfounded model in which unsystematic risks, supply-side effects and the potential for investor impact on the externality are all priced. Calibration to empirical results suggests a $1 increase in long-term investor demand generates 3 cents of firm assets, but with large potential cross-sectional variation. This implies significant opportunities for positive impact, but also for harm if demand shifts are too aggressive. The framework provides a foundation for quantitative models that address topics like universal ownership and impact investing, including defining the concepts of contribution multipliers, prices of impact, impact returns, and impact frontiers.
