Join the the Externality Investment Research Network
If you are a researcher, academic, practitioner, or thinker Interested in understanding how economic externalities impact diversified and typically large portfolios, and how they, when quantified and valued, influence risk and investment strategies, the Externality Investment Research Network (EIRN) invites you to join as an interdisciplinary community dedicated to advancing this next frontier in financial research and practice.
Why EIRN?
The EIRN was created to address a fundamental gap in financial research: the lack of quantitative analysis on how economic externalities affect the portfolios of asset owners and managers. While the "universal owner effect" or "whole portfolio effect" is now widely acknowledged in theory and in case studies, actionable, data-driven models to operationalize it remain scarce. Our goal is to fill this gap.
