THE PHILLIPS CURVE AND A MICRO-FOUNDATION OF TREND INFLATION

  • Taiji HARASHIMA

Abstract

The hybrid New Keynesian Phillips curve has been criticized for lacking a micro-foundation. In this paper,
an alternative purely forward-looking model of the Phillips curve is constructed on the basis of a micro-foundation
of trend inflation. In addition, another source of output gaps other than frictions―a Nash equilibrium of a Pareto
inefficient path―is considered. The model indicates that the role of frictions has been overestimated and that
frictions are less important than previously have been thought. The conventional monetary policy of utilizing
frictions cannot necessarily stabilize inflation. In contrast, the monetary policy of controlling the government’s
preference is very effective. A problem is that the effects of both types of monetary policy are not distinguishable.
