Reference excerpt

Peter Wilkinson Howitt (born May 31, 1946) is a Canadian economist and the Lyn Crost Professor of Social Sciences Emeritus at Brown University. He is best known for his collaborative work with Philippe Aghion on endogenous growth theory, the concept of creative destruction in modern macroeconomics and the Aghion–Howitt model. In 2025, Howitt and Aghion were jointly awarded the Nobel Memorial Prize in Economic Sciences "for the theory of sustained growth through creative destruction."

Early life and education Howitt was born in Guelph, Ontario, in 1946. He earned his BA in economics from McGill University in 1968, his MA from the University of Western Ontario in 1969, and his PhD from Northwestern University in 1973 under Robert W. Clower.

Academic career Howitt returned to Canada after receiving his PhD and taught at the University of Western Ontario from 1972 to 1996. He became a faculty member at the Ohio State University in 1996 and joined Brown University in 2000, where he has remained since. Since 2013, Howitt is Professor Emeritus at Brown University. Besides his university affiliations, he also has long-time connections with the C. D. Howe Institute, a nonpartisan think tank based in Toronto, Canada. Howitt started publishing reports of economic policy through the institute since 1986 and was a fellow-in-residence from 2011 to 2015. He served as president of the Canadian Economics Association in 1993–1994 and was the editor of the Journal of Money, Credit, and Banking in the period 1997–2000.

Honours and awards Howitt was elected a Fellow of the Royal Society of Canada in 1992 and of the Econometric Society in 1994. In 2019, he and Aghion received the BBVA Foundation Frontiers of Knowledge Award in Economics, Finance and Management. Howitt and Aghion were also awarded half of the Nobel Memorial Prize in Economic Sciences in 2025 "for the theory of sustained growth through creative destruction", the other half going to Joel Mokyr.

Illustrations

Worked examples

Example 1 — a first encounter with Peter Howitt (economist)

Start with the simplest possible case. Write down what Peter Howitt (economist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Peter Howitt (economist) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Peter Howitt (economist) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Peter Howitt (economist)

In research: Peter Howitt (economist) appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Peter Howitt (economist) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Peter Howitt (economist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1946 births, 20th-century Canadian economists, 21st-century Canadian economists, so understanding it makes those chapters shorter.
In everyday life: Look for Peter Howitt (economist) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
