The big buzzwords among the executives and world leaders at the World Economic Forum’s annual meeting this year were “stakeholder capitalism,” the idea that a corporation should serve a social and environmental good, not just enrich shareholders. What a concept, right? It comes after those Business Roundtable guidelines on corporate responsibility, and sustainability pledges from big players like Microsoft and BlackRock. But is this really a challenge to Milton Friedman’s 50-year-old treatise on corporations’ purpose? Or just a savvy but cynical PR move? We put that question to Jerry Davis, the associate dean for business and impact at the University of Michigan’s business school. He says it’s harder for a company to be a “successful hypocrite” now.
