The labor market is receiving increasing attention in the New Keynesian literature. In this paper I critically survey this literature in order to highlight the role played by wage rigidities in the explanation of fluctuations caused by technology shocks. To this aim, I present a DSGE model with...

This paper estimates and compares four versions of the sticky price New Keynesian model for the Euro area, using a Bayesian approach as described in Rabanal and Rubio-Ramírez (2003). The authors find that the average duration of price contracts is between four and eight quarters, similar to the...

We study the implications for optimal monetary policy of introducing habit formation in consumption into a general equilibrium model with sticky prices. Habit formation affects the model's endogenous dynamics through its effects on both aggregate demand and households' supply of output. We show...

We present a new way of empirically evaluating various sticky price models used to assess the degree of monetary non-neutrality. While menu cost models uniformly predict that price change skewness and dispersion fall with inflation, in the Calvo model both rise. However, CPI price data from the...

This paper studies the state-dependent effects of monetary policy shocks. It shows that a canonical sticky-price model with real rigidity in the form of firm-specific factors can generate substantial state-dependence in the effects of monetary policy shocks. Factor specificity introduces a...

Output growth is negatively correlated with inflation and detrended output is positively correlated with inflation in the major North American and European economies. In addition, output growth and detrended output lead inflation. I explore the consistency of these correlations with three models...

We present a sticky-price model incorporating heterogeneous firms and systematic firm-level productivity trends. Aggregating the model in closed form, we show that it delivers radically different predictions for the optimal inflation rate than canonical sticky price models featuring homogenous...

Sticky price models featuring heterogeneous firms and systematic firm-level productivity trends deliver radically 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...

This paper documents how the frequency of price changes differs across sectors in Korea and what implications such heterogeneity may have for monetary policy. We find that under heterogeneity: i) monetary policy has larger and more persistent real effects; ii) it is welfare improving to...
