This paper studies the challenge that increasing the inflation target poses to equilibrium determinacy in a medium …-sized New Keynesian model without indexation fitted to the Great Moderation era. For moderate targets of the inflation rate …

restrictions which are not rejected by the data - the cost channel helps to generate an initial rise of inflation after a monetary …

different predictions for the optimal inflation rate than their popular homogenous-firm counterparts: (1) the optimal steady …-state inflation rate generically differs from zero and (2) inflation optimally responds to productivity disturbances. We show this by … estimate the historically optimal inflation path for the U.S. economy. In the year 1977, the optimal inflation rate stood at 1 …

Keynesian model we show that, if households have hyperbolic discounting, small positive rates of inflation can be optimal. In … our baseline calibration, the optimal rate of inflation is 2.1% and remains positive across a wide range of calibrations …

In this paper we propose an alternative explanation for the nature, sources and consequences of inflation rate … catching-up and inflation differentials and offer an interpretation of the nature of this interaction. Our discussion is in … inflation rates between Member States do not necessarily have to be an equilibrium phenomenon, even if the original shock comes …
