The revealed preference approach in economics is central to the empirical analysis of consumer behavior. This paper introduces the Stata commands checkax, aei, and powerps as a bundle within the package rpaxioms. The first command allows a user to test whether consumer expenditure data satisfy a number of revealed preference axioms; the second command calculates measures of goodness-of-fit when the data violate these axioms; and the third command calculates power against uniformly random behavior as well as predictive success for each axiom. The commands are illustrated using individual-level experimental data and household-level aggregate consumption data.
