__(with Ludovic Renou),__**Afriat's Theorem and Samuelson's 'Eternal Darkness'**__,__**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 (__: 10.1016/j.jmateco.2016.05.003).__*doi*__: Leicester 2016.__*Working Papers*

__(with Ian Crawford),__**Testing for Intertemporal Nonseparability****,**__Journal of Mathematical Economics__**2014**. Establishes an observational equivalence between habit formation and anticipation in finite data containing prices, interest rates, and consumption choices (*: 10.1016/j.jmateco.2014.03.007).*__doi__*: IFS 2013, Leicester 2013.*__Working Papers__

__(with John K.-H. Quah),__**Revealed Preference in a Discrete Consumption Space****,**__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) (*: 10.1257/mic.5.1.28).*__doi__*: IFS 2012, Leicester 2012.*__Working Papers__
