This paper presents an investigation of the empirical significance of the Lucas Critique for the Phillips Curve. Finally, there are very good reasons to believe that the Fed’s 2 percent inflation target is too low; certainly the belief that it was high enough to make the zero lower bound irrelevant has been massively falsified by experience. But one can fully accept that inflation is driven by an excess supply of money without denying that there is a link between inflation and unemployment. Why does the Fed believe that inflation is going to rise? We’re currently well above historical estimates of full employment, and inflation remains subdued.
