… is from page 13 of my GMU Econ colleague Dan Klein’s superb new book, Knowledge and Coordination :
It is one thing for the entrepreneur to greet fortune when it comes knocking. It is something else to apprehend fortune in its hidden forms and seize it. Here, we have the distinction between responding to the realization of events within a framework of recognized variables and relationships and the discovery of a fresh opportunity to embrace a new and better framework of interpretation. This element of epiphany, of finding fortune by interpreting the world differently, is the subtle and vital element in human decision making. Yet, it is absent from equilibrium model building. In equilibrium stories, agents never have a “light bulb” moment.
