A Multimarket Approach for Estimating a New Keynesian Phillips Curve

We propose a new approach for estimating a “hybrid” New Keynesian Phillips Curve (NKPC)that includes demand pressures coming from disequilibrium relations in three differentmarkets: (1) monetary and financial, (2) international, and (3) labour. The results of theapplication of this approach show that all three markets contribute to the evolution of inflation. However, shocks on equilibrium in the labour market and short-run movements in cyclical output are relatively more important than other shocks. Econometric tests indicate that this specification is superior to the traditional NKPC, which includes a single variable to account for demand pressures.
