Growth, education and environment

In this interview, Philippe Aghion, professor of economics at Harvard University, returns to the contributions of new economic theories of growth that he has helped develop since the late 1980s. He examines the role of the system and banking, state (budgetary, industrial and educational and research policies) and ecological innovations for growth. He also presents his recommendations to improve research policy in France and Europe.

Former pupil of the School Normale Supérieure de Cachan, doctor of economics in Paris 1 and in Harvard, Philippe Aghion is a member of the Economic Analysis Council (Cae), associate researcher in Bruegel, and was part of the Commission for the Liberation of French Growth, known as Attali Commission, whose report was rendered on January 23, 2008 to President Nicolas Sarkozy. He was recently charged by Minister Valérie Pécresse for a report on the university reform.

He first developed, with Peter Howitt, a theory of growth known as “ Schumpeterian Which emphasizes the importance of technological innovation. He then extended this theoretical framework to many areas, such as the impact of growth on inequalities, the analysis of credit constraints and financial liberalization, the role of education and investments in research. He is also a specialist in contract theory and organizational economics.
