Biography
Peter Wilkinson Howitt (born May 31, 1946) is a Canadian economist and the Lyn Crost Professor of Social Sciences Emeritus at Brown University. Born in Guelph, Ontario, Howitt studied at several prestigious institutions, including Northwestern University, Western University, and McGill University. His academic background gave him a solid footing in economic theory, which informed his groundbreaking contributions to macroeconomics.
Howitt is internationally recognized for his work with Philippe Aghion on endogenous growth theory and the development of the Aghion-Howitt model. Their research changed how we understand long-term economic growth through creative destruction, building on the earlier work of Joseph Schumpeter. The model shows how innovation and technological progress drive economic expansion by constantly replacing outdated technologies and business practices with newer, more efficient ones.
Throughout his career, Howitt has received many prestigious honors for his contributions to economic science. He was elected a Fellow of the Econometric Society in 1994 and later became a Fellow of the Royal Society of Canada. In 2014, he was named among the Clarivate Citation Laureates, an honor often seen as a precursor to the Nobel Prize. In 2022, the University Côte d'Azur awarded him an honorary doctorate, acknowledging his global impact in the field.
The highlight of Howitt's career came in 2025 when he and Philippe Aghion jointly received the Nobel Memorial Prize in Economic Sciences "for the theory of sustained growth through creative destruction." This recognition validated decades of research that fundamentally changed how economists and policymakers understand economic growth. Their work has profound implications for innovation policy, technological change, and the role of entrepreneurship in today's economies.
Beyond his theoretical contributions, Howitt's work has tangible applications for economic policy and development strategies. His research provides insights into how governments can encourage innovation and technological progress to achieve sustainable economic growth. The endogenous growth framework he helped create is now a key part of modern macroeconomic theory and continues to influence academic research and policy discussions around the world.
Before Fame
Growing up in Guelph during the 1950s and 1960s, Howitt experienced a time of rapid economic growth and technological progress in Canada. The economic boom after the war made understanding the sources of economic growth more important to both policymakers and academics.
His education at Northwestern University, Western University, and McGill University introduced him to various economic ideas and methods. The economic situation in the 1970s, with stagflation and the perceived failure of the usual Keynesian models, gave young economists the chance to create new theories that could better explain long-term growth and technological changes.
