Duncan Webb

I'm a PhD student at the Paris School of Economics. I am a development economist who uses tools and insights from behavioural economics. My current projects focus on discrimination, social change, and human capital.

Later this year I'll be joining Princeton University as a postdoctoral scholar, before joining NovaSBE as an Assistant Professor in 2025.

I spent 2022-23 as a visiting scholar at MIT, and 2021 at UC Berkeley, and I'm a Global Priorities Fellow supported by the Forethought Foundation.
