Summary

In this inaugural lecture at Sciences Po’s School of Management and Impact, Philippe Aghion presents the power of creative destruction, a concept originating from Joseph Schumpeter. He explains how innovation drives economic growth by replacing outdated technologies and firms, but also creates tensions. Aghion outlines the Schumpeterian growth paradigm, which he developed with Peter Howitt, emphasizing three key ideas: growth is driven by cumulative innovation, innovations are motivated by monopoly rents, and new innovations destroy old ones. He highlights the central contradiction of capitalism: the need to reward innovators while preventing them from blocking future innovations. Using this framework, he revisits economic enigmas such as secular stagnation, the middle-income trap, and inequality. He argues that the slowdown in US productivity growth after 2005 was due to the rise of superstar firms that discouraged entry, not a lack of ideas. He also discusses the middle-income trap, using Korea and Japan as examples where conglomerates hindered competition and innovation. Aghion contrasts Europe’s decline with US dynamism, noting that Europe’s top patenting firms have remained stagnant while the US has seen turnover. He emphasizes the importance of competition policy, education, and social protection to harness innovation for inclusive growth. He also addresses the potential of AI to boost growth but warns of risks like job displacement and concentration. The lecture concludes with a call for policies that foster creative destruction while managing its social costs.
