This paper investigates the effects of monetary policy in presence of heterogeneous consumers. We study the effectiveness (quantitative effects) of monetary policy and equilibrium determinacy properties of a New Keynesian DSGE model where a fraction of households cannot smooth consumption. We...

This paper develops a simple New Keynesian Dynamic Stochastic General Equilibrium (DSGE) model with rule-of-thumb consumers and external habits. Our theoretical model has a closed-form solution which allows the analytical derivation of its dynamical and stability properties. These properties are...

This paper presents a New Keynesian model characterized by labor indivisibilities, unemployment and a unionized labor market. The bargaining process between unions and firms introduces real wage rigidity and creates an endogenous trade-off between inflation and output stabilization. Under an...

This paper estimates and compares New-Keynesian DSGE monetary models of the business cycle derived under two different pricing schemes - Calvo (1983) and Rotemberg (1982) - under a positive trend inflation rate. Our empirical findings (i) support trend inflation as an empirically relevant...

A New Keynesian model characterized by labor indivisibilities, unemployment and a unionized labor market is presented. The bargaining process between unions and firms introduces real wage rigidity and creates an endogenous trade-off between inflation and output stabilization. Under an optimal...

We propose a flexible prices model where endogenous market structures and search and matching frictions in the labor market interact endogenously. The interplay between firms endogenous entry, strategic interactions among producers and labor market frictions represents a strong amplification...

Calvo pricing implies output gains, while Rotemberg pricing implies output losses after a disinflation. Introducing real wage rigidities has opposite effects: it generates a long-lasting boom in output in Calvo, and a moderate output slump in Rotemberg.

The aim of this paper is to investigate both the efficacy and the stability properties of monetary policy rules in presence of heterogeneous consumers. We aim to underline the link between the well- known Taylor Principle and the demand-policy regimes, defined on the basis of the monetary policy...
