Joel Kariel

Econometrics Adviser

Competition & Markets Authority

From May 2023, I will start working at the Microeconomics Unit at the Competition & Markets Authority. Previously, I was a postdoctoral researcher at the University of Kent working with Anthony Savagar on scale economies in the UK. I completed my DPhil in Economics at the University of Oxford under the supervision of Petr Sedlacek.

My research interests are in technological change, market power, firm dynamics, and productivity. I am in the early stages of various projects on `green technologies’: looking at their adoption, relationship with climate policy, and impact on firms.

I was awarded BA Leverhulme Small Research Grant 2022. I am working on racial discrimination in the labour market for professional footballers with an RA. The job advert can be found here. Initial findings will be available in early 2023.
