*American Economic Review***2020**. Develops and implements a nonparametric method called Generalized Restriction of Infinite Domains (GRID), for testing the consistency of contingent consumption data with a broad class of models of choice under risk and under uncertainty (

__(with__**Afriat's Theorem and Samuelson's 'Eternal Darkness'**__Ludovic Renou__),__,__**Journal of Mathematical Economics****2016**. Provides a new proof of Afriat's Theorem, which highlights why a concave rationalization is without loss of generality in a classical finite data setting (__:__*doi*__10.1016/j.jmateco.2016.05.003__).

__(with__**Testing for Intertemporal Nonseparability**__Ian Crawford__),**,**__Journal of Mathematical Economics__**2014**. Establishes an observational equivalence between habit formation and anticipation in finite data containing prices, interest rates, and consumption choices (*:*__doi____10.1016/j.jmateco.2014.03.007__).

__(with__**Revealed Preference in a Discrete Consumption Space**__John K.-H. Quah__),**,**__American Economic Journal: Microeconomics__**2013**. Shows that an agent maximizing utility on a discrete (instead of continuous) consumption space still obeys the generalized axiom of revealed preference (GARP) (*:*__doi____10.1257/mic.5.1.28__).
