Revealed Preference Analysis with Partially Observed Prices (with Ian Crawford and Carl-Emil Pless), 2025. Demonstrates that revealed preference analysis remains feasible in the presence of partially observed prices, even while agnostic about the nature of missing prices.

Money Pumps and Bounded Rationality (with Joshua Lanier and John K.-H. Quah), 2024. Explores money pumps in relation to (departures from) economic rationality. Working Paper: arXiv:2404.04843.

Unpublished Working Papers

Rationalizability, Cost-Rationalizability, and Afriat's Efficiency Index (with John K.-H. Quah), 2024. Establishes a definitional equivalence between rationalizability and cost-rationalizability under mild conditions, as well as an observational equivalence within the context of finite data, furnishing support for a natural interpretation of Afriat's (1973) critical cost efficiency index (CCEI).

A Lattice Test for Additive Separability, 2018. 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.

Ambiguity Revealed (with Ralph-C. Bayer, Subir Bose, and Ludovic Renou), 2013. Derives and implements revealed preference tests for variational preferences, maxmin expected utility, and subjective expected utility.
