**2024**. 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 small relative to departures from ordering (completeness and transitivity) and/or monotonicity with respect to first-order stochastic dominance (FOSD).

**Rationalizability, Cost-Rationalizability, and Afriat's Efficiency Index**__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).

__, 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.__

**Demand Analysis with Partially Observed Prices**__Ian Crawford__), 2016. Demonstrates that demand analysis remains feasible in the presence of partially observed prices, even while agnostic about the nature of missing prices.
