A well-known problem with revealed preference methods is that when data are found to satisfy their restrictions it is hard to know whether this should be viewed as a triumph for economic theory, or a warning that these conditions are so undemanding that almost anything goes. This paper allows researchers to make this distinction. Our approach uses an axiomatic characterization of a measure of predictive success due to Selten (1991). We illustrate the idea using a panel dataset. The results show that this approach can lead us to radically reassess our view of the empirical performance of economic theory.
