**2021**. 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).

**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).
