While he sneers at everyone else’s epistemic criteria and explanatory demands, it is significant that Williamson never once feels impelled to make explicit his own nonnegotiable litmus test for legitimate purposes in construction of models. Yet, looking back over his defense, it becomes clear: it is political, in the sense that if a particular model helps reify the neoliberal worldview, than it passes muster a fortiori. Williamson is subconsciously aware of this, since he turns swiftly to indict Quiggin for believing that proponents of DSGE, and zombie economics more generally, are “complicit in the conspiracy to make the rich richer by robbing the poor.”
