Abstract

The standard New Keynesian model suffers from the so-called .macro-micro pricing conflict:in order to match the dynamics of inflation implied by macroeconomic data, the model needsto assume an average duration of price contracts which is much longer than what is observedin micro data. Here I show how departing from the standard model's assumption of aperfectly competitive labor market can help resolve the pricing conflict. I do so by assumingsearch frictions in the labor market. In this framework, labor becomes firm-specific andmarginal cost curves become upward-sloping. This mechanism reduces the slope of the NewKeynesian Phillips curve given a frequency of price adjustment. Conversely, given anestimate of this slope, my model implies shorter price durations than the standard model. Fora plausible calibration and for different slope values, my model consistently delivers pricedurations that are roughly half of those implied by the standard model.
