摘 要：We provide a non-parametric revealed preference test which allows us to determine if one person is more risk averse (or impatient, selfish, uncertainty averse, complexity averse, etc.) than a second. Specifically, given finite datasets on two decision makers we are able to test if there exists utility functions which rationalize the observed behavior where the second utility function is more risk averse (or more impatient, more selfish, etc.) than the first. For many comparative concepts of interest (for instance, Yaari's notion of more risk averse) our test takes the form of a simple acyclicality condition on a pair of modified revealed preference relations. More generally, our test can be implemented by solving a mixed integer program. Our test can be applied with the Yaari (1969) notion of more risk averse, the Epstein (1999) notion of more uncertainty averse, the Ok and Benoit (2007) notion of more impatient, and the Puri (2018) notion of more complexity averse. Several other applications are also given.
