Intrinsic persistence of wage inflation in New Keynesian models of the business cycles

Giovanni Di Bartolomeo () and Marco Di Pietro ()

No 55, Dynare Working Papers from CEPREMAP

Abstract: Our paper derives and estimates a New Keynesian wage Phillips curve that accounts for intrinsic inertia. Our approach considers a wage-setting model featuring an upward-sloping hazard function, that is based on the notion that the probability of resetting a wage depends on the time elapsed since the last reset. According to our specification, we obtain a wage Phillips curve that also includes backward-looking terms, which account for persistence. We test the slope of the hazard function using GMM estimation. Then, placing our equation in a small-scale New Keynesian model, we investigate its dynamic properties using Bayesian estimation. Model comparison shows that our model outperforms commonly used alternative methods to introduce persistence.
