My research covers areas of public economics and labour economics. All of it is applied, using large micro-datasets of individuals or households, and most is about policy.
You can find links to all of my work in one of two places: there is a complete list of my work after 2011 at my page at the University of Essex. For older stuff, you can use my page at the Institute for Fiscal Studies. My ResearchGate page and my Google scholar page span both eras, but they are not guaranteed to be complete.
