- A Lattice Test for Additive Separability, IFS Working Papers, W18/08, Institute for Fiscal Studies, 2018. Short Abstract: Establishes necessary and sufficient conditions for a finite data set of price and demand observations to be consistent with an additively separable preference, with an empirical application to panel expenditure data on food purchases. Working Paper Versions: IFS 2018, St Andrews 2018. Slides: Print/View.
- Revealed Preferences over Risk and Uncertainty (with John K.-H. Quah and Ludovic Renou), School of Economics and Finance Discussion Papers, 1706, University of St Andrews, 2017. Short Abstract: Develops and implements a nonparametric procedure, called the lattice method, for testing the consistency of contingent consumption data with a broad class of models of choice under risk and under uncertainty. Slides: Short (Print/View), Long (Print/View). Working Paper Versions: St Andrews 2017, QMUL 2017, IFS 2015, Oxford 2015, Leicester 2013.
- Demand Analysis with Partially Observed Prices (with Ian Crawford), Discussion Papers in Economics, 15/12, University of Leicester, 2016. Short Abstract: Demonstrates that demand analysis remains feasible in the presence of partially observed prices, even while agnostic about the nature of the missing prices. Working Paper Versions: Leicester 2016, IFS 2015.
