Biography
Philippe Mario Aghion, born August 17, 1956, in Paris, is a French economist known for his groundbreaking work on endogenous growth theory, which changed the way economists view long-term economic development. He currently holds several prestigious academic roles, including Chair of Economics of Institutions, Innovation and Growth at the Collège de France, Kurt Björklund Chaired Professor in Innovation and Growth at INSEAD, and Professor of Economics at the London School of Economics.
Aghion studied at some of France's top institutions, such as the École normale supérieure Paris-Saclay and the University of Paris 1 Panthéon-Sorbonne, before completing further studies at Harvard University. This blend of French academic training and American economic methods later influenced his innovative approach to growth theory.
His most significant contribution to economics came with his collaboration with Peter Howitt in developing the Aghion-Howitt model. This model transformed the understanding of how economies maintain long-term growth through creative destruction, showing how innovation drives economic progress by creating new technologies and making older ones obsolete. It provided a mathematical framework for Joseph Schumpeter's earlier ideas.
Throughout his career, Aghion has received numerous honors for his contributions to economics. He won the Yrjö Jahnsson Award in 2001, became a Fellow of the Econometric Society in 1993, and received the CNRS silver medal in 2006. The French government honored him by naming him Knight of the Legion of Honour in 2012 and Officer of the National Order of Merit in 2018. In 2025, he and Peter Howitt shared the Nobel Memorial Prize in Economic Sciences for their theory on sustained growth through creative destruction.
Beyond his theoretical work, Aghion has influenced economic policy and institutional design in several countries. His research has shaped approaches to innovation policy, competition regulation, and industrial strategy, making him one of the most practically impactful economists of his generation.
Before Fame
Growing up in Paris during the post-war economic boom, Aghion experienced France's fast-paced modernization and European integration. This period of change and economic development probably shaped his interest in how institutions and innovation drive growth.
He went through France's grande école system, especially at École normale supérieure Paris-Saclay, where he received strong mathematical training crucial for his later theoretical work. By choosing to study further at Harvard University, he found himself at the heart of the economics field in the 1980s, a time when there was a growing interest in exploring the sources of long-term economic growth.
Key Achievements

Did You Know?
- 01.He developed his famous growth model with Peter Howitt while both were relatively young economists, fundamentally challenging the prevailing Solow growth model that had dominated economics for decades
- 02.His work bridges the gap between theoretical economics and practical policy, with his research directly influencing competition policy in both Europe and the United States
- 03.He holds simultaneous professorships at three major institutions across different countries, reflecting the international scope of his influence
- 04.The Aghion-Howitt model was initially met with skepticism by some established economists but eventually became a cornerstone of modern macroeconomic theory
- 05.He was named to the Clarivate Citation Laureates in 2014, which predicted his eventual Nobel Prize recognition eleven years before it occurred
