We provide revealed preference axioms that characterize models of translation invariant preferences. In particular, we characterize the models of variational, maxmin, CARA and CRRA utilities.  In each case, we present a revealed preference axiom that is satisfied by a dataset if and only if the data set is consistent from the corresponding utility representation.  Our results complement traditional exercies in decision theory that take preferences as primitive.
