We have now reached an impasse of the kind philosophers call a paradox: a set of statements, all of which seem individually acceptable or even unquestionable but which, when taken together, are jointly contradictory. These are the statements:
(1) Economic models are false.
(2) Economic models are nevertheless explanatory.
(3) Only true accounts can explain.When facing a paradox, one may respond by either giving up one or more of the jointly contradictory statements or else challenge our logic. I have not found anyone writing on economic models who has explicitly challenged logic (though their writings sometimes suggest otherwise).
