Professor of Economics
Professorial Fellow

Research Interests: Empirical microeconomics.

I am a Professorial Fellow at Nuffield College, and a Professor of Economics in the Department of Economics, University of Oxford.  My main research interests are in structural empirical microeconomics (combining microeconomic theory and microeconomic data as seamlessly as possible).

Currently I'm working on projects in three main areas: revealed preference methodsindex numbers and heterogeneity.  Under revealed preferences I'm working on a characterisation of reference-dependence (with Laura Blow and Vince Crawford) and a project on price uncertainty and stochastic choice (with Daniel Martin). I have two main projects under index numbers: the first on new-characteristics bias in hedonic price indices (with Peter Neary), the second on measuring inflation with partially observed prices (with Matt Polisson). On heterogeneity I have a project on measuring taste change joint (with Abi Adams, Richard Blundell and Martin Browning) plus some new work on estimating individual-by-individual labour-supply models using random fields. Current drafts of papers, or slides, are available on my research pages.

I am also a member of the (Technical) Advisory Panel on Consumer Price for the Office for National Statistics.
