In this episode, Hunt Allcott, Professor of Global Environmental Policy at Stanford University, shares the learnings from his research on economic approaches to measuring social impact of companies' business activities. In the episode we explore what motivated him to investigate this topic, his unique approach to measuring impact using positive and negative externalities of enterprise activity in dollar terms as well as the surprising findings from applying this novel approach to 74 firms across 12 industries. We also discuss what Hunt believes might be the implications of his research on monetization of impact and its potential integration into social and financial performance metrics as well as what that could mean for impact investing practitioners moving forward.
