“It’s fantastic, Peter, isn’t that great? Yes! Yes!”

Listen to the moment Philippe Aghion shares his joy with his friend and co-laureate Peter Howitt, captured as part of this call made shortly after the public announcement of the 2025 economic sciences prize. In this interview, Aghion also discusses the implications of their ‘creative destruction’ model of sustained economic growth – and reveals his surprise at the news.

Thrilled to see Philippe receive the Nobel Prize! It’s been such a privilege to work with him and benefit from his mentorship!
