Joel Mokyr, Philippe Aghion, and Peter Howitt won the 2025 Nobel Prize in Economics for their work in the theory of sustained growth through creative destruction. Today, a friend and I went to see Philippe Aghion speak about this work at Ekonomikum in Uppsala. The lectures are organized every year by the university and are open to the public, with no pre-registration. My rough notes are below [L: As usual, my own comments are embedded like this.].
