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...

We analyze, in this paper, DSNK general equilibrium model with indivisible labor where firms may belong to two different final goods producing sectors: one where wages and employment are determined in competitive labor markets and the orther where wages and employment are the result of a...

We study Ramsey monetary policy in a New Keynesian (NK) model with endogenous growth and knowledge spillovers external to each firm. We find that in contrast with the standard NK model, the Ramsey dynamics implies deviation from full inflation targeting in response to technology and government...

This paper shows that nominal rigidities in terms of price stickiness acts as a powerful supply-shock filter that reduces the overall economic instability. Considering a range of admissable values for price stickiness, the volatility of inflation, output and interest rate induced by technology...

Since the '80s the volatility of output growth and inflation experienced by several industrialized countries has remarkably declined, what has been dubbed the "Great Moderation". Various explanations have been proposed and likely all play some role. This paper shows that when an industrial...

Recent U.S. evidence suggests that the response of labor share to a productivity shock is characterized by countercyclicality and overshooting. These findings cannot be easily reconciled with existing business cycle models. We extend the Diamond-Mortensen-Pissarides model of search in the labor...

We introduce endogenous growth in a standard NK model with staggered prices and wages. We find that the source of nominal rigidities, the shock persistence and the type of Taylor rule affect the relationship between monetary volatility and growth.

We introduce endogenous growth in an otherwise standard NK model with staggered prices and wages. Some results follow: (i) monetary volatility negatively affects long-run growth; (ii) the relation between nominal volatility and growth depends on the persistence of the nominal shocks and on the...
