On Phase Shifts in a New Keynesian Model Economy

The purpose of this paper is focus directly on the phase shift. For one thing, we ask whether a sticky-price model economy can account for both countercyclical prices and procyclical inflation. We present findings in which the price level is countercyclical and the inflation rate is procyclical. We proceed to use the model economy as an identification mechanism. What set of individual shocks are sufficient to account for the phase shift? That set is empty. Next, we ask what set of shocks are necessary to account for the phase shift.
