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__.**(with**

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