Resumen de Testing axioms of revealed preference in Stata

Marcos Demetry, Per Hjertstrand, Matthew Polisson

• The revealed preference approach in economics is central to the empirical analysis of consumer behavior. In this article, we introduce the 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 several 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. We illustrate the commands using individual-level experimental data and household-level aggregate consumption data.
