Ayden Higgins

Postdoctoral Researcher, University of Oxford

I completed a PhD in Economics at the University of Surrey in 2021 and am presently working as a postdoctoral researcher at the University of Oxford. My research mainly focuses on panel data econometrics, particularly factor models, spatial models and models of unobserved heterogeneity. I also work on bootstrap methods and their application to panel data. A catalogue of my research can be found below. Click here for a copy of my CV.
I am on the 2023/2024 job market.
