Inflation surprises in a New Keynesian economy with a “true” consumption function

Author

Listed:
  • Roberto Tamborini
Abstract
The resurgence of inflation has been accompanied by a reversal of prospects of growth, with a prominent role assigned to the fall of households' purchasing power. Yet this real income effect of inflation surprises, independent of restrictive monetary policy, is not present in the standard New Keynesian models for monetary policy. The reason lies in the formulation of the consumption‐based “IS equation”. The paper shows how the income effect can be introduced by reformulating the consumption function, with the consequence that it exerts an autonomus stabilization effect on inflation. The main monetary policy implications are examined by means of simulations.
