Radical Uncertainty and New Sector Emergence: An Action Theory of Co‐Creative Stakeholders
Strategic Change, EarlyView.ABSTRACT For much of the past century, entrepreneurship scholars have sought to understand and assess the nature, role, and impact of uncertainty. While the sum total of this work has contributed valuable insights, radical uncertainty—characterized by dynamic conditions in which outcomes are unknowable at the time action must be taken—remains weakly ...
