Revealed Preferences over Risk and Uncertainty (with John K.-H. Quah and Ludovic Renou), 2019.
- 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.

A Lattice Test for Additive Separability, 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 data on food purchases.

- Slides: Additive Separability.
Demand Analysis with Partially Observed Prices (with Ian Crawford), 2016.
- Short Abstract: Demonstrates that demand analysis remains feasible in the presence of partially observed prices, even while agnostic about the nature of missing prices.
- Working Papers: Leicester 2016, IFS 2015.
