This year's World Economic Forum Annual Meeting takes up the theme of stakeholder capitalism—a system based on a business model that serves "clients, shareholders, workers, and employees, as well as societies," as Klaus Schwab writes in the introduction of this special Foreign Affairs collection. Companies must reform capitalism from within, Schwab warns, before others force change from the outside. In the essays that follow, all drawn from the pages and pixels of Foreign Affairs, some of the world's leading scholars and practitioners explore the central threats—political, economic, technological, environmental—to a cohesive world today and chart possible routes to a more sustainable future.
