This even happens with key critics like Joseph Stiglitz. In a long meditation on the flaws of macroeconomics, he suggests the DSGE was the wrong place to start to formalize macroeconomics, and that even when well-meaning Keynesians tinker with it to address the chorus of complaints, “the improved macro-performance is accompanied by an increased arbitrariness in at least certain specifications . . . the DSGE models have made the wrong trade-offs, focusing on some complexities which are of less importance than those they ignore”; and yet, in the very same paper, he reveals his own ambivalence, writing, “no one can object to models that approximately model the general equilibrium properties of dynamic economies facing endogenous and exogenous shocks, so on one level DSGE is unobjectionable.” No one, that is, except those who trace the disease to the neoclassical model itself.
