Entrepreneurship and growth: lessons from an intellectual journey

This lecture is the story of an intellectual journey, that of elaborating a new-Schumpeterian-theory of economic growth. A theory where (i) growth is generated by innovative entrepreneurs; (ii) entrepreneurial investments respond to incentives that are themselves shaped by economic policies and institutions; (iii) new innovations replace old technologies: in other words, growth involves creative destruction and therefore involves a permanent conflict between incumbents and new entrants. First, we motivate and then lay out the Schumpeterian paradigm and point to a set of empirical predictions which distinguish this paradigm from other growth models. Second, we raise four debates on which the Schumpeterian approach sheds new light: the middle income trap, secular stagnation, the recent rise in top income inequality, and firm dynamics. Third and last, we show how the paradigm can be used to think (or rethink) about growth policy design.
