 Conceptualizing of economic inquiry as the study of models and tendencies, seems to shift the terms of the problems posed by inexactness rather than to offer a solution. Julian Reiss has, in effect, rediscovered the problem in an influential essay, “The Explanation Paradox.” (2013), where he argues that the following three propositions are inconsistent: (1) Economic models are false. (2) Economic models are explanatory. (3) Explanation requires truth.The formulation is a bit obscure, since models are not single sentences or propositions that can be true or false, but it should be clear that Reiss’s putative paradox is a reformulation of the problem posed by the inexactness of economic theories or models.
