Rationalizability, Cost-Rationalizability, and Afriat's Efficiency Index (with John K.-H. Quah), 2022. 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). Working Papers: Bristol 2022, IFS 2022.
Ever Since Allais (with Aluma Dembo, Shachar Kariv, and John K.-H. Quah), 2021. Reports an experiment that nonparametrically tests the entire set of axioms on which expected utility theory (EUT) is based, and finds that within-subjects departures from independence are minor relative to departures from ordering (completeness and transitivity) and/or monotonicity with respect to first-order stochastic dominance (FOSD). Working Papers: Bristol 2021. [Revise and Resubmit, Journal of Political Economy]
Revealed Preferences over Risk and Uncertainty (with John K.-H. Quah and Ludovic Renou), 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 (doi: 10.1257/aer.20180210).
