We formulate and estimate a business cycle model which can account for key business cycle properties of labor market variables and other aggregates. Three features distinguish our model from the standard model with Search And Matching (SAM) frictions in the labor market: frictional firm entry,...

Using U.S. quarterly data we provide VAR evidence showing that a positive productivity shock leads to a persistent decrease in the unemployment rate and in the price markup, together with an increase in aggregate profits. In response to the shock the labor share of income decreases on impact and...

We study the effects of progressive labor income taxation in an otherwise standard NK model. We show that progressive taxation (i) introduces a trade-off between output and inflation stabilization and affects the slope of the Phillips Curve; (ii) acts as automatic stabilizer changing the...

This paper extends the standard New Keynesian dynamic stochastic general equilibrium (DSGE) model to agents who cannot smooth consumption (i.e. spenders) and are affected by external consumption habits. Although these assumptions are not new, their joint consideration strongly affects some...

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...

We study monetary policy in a New Keynesian (NK) model with endogenous growth and knowledge spillovers external to each firm. We find the following results: (i) technology and government spending shocks have different effects on growth; (ii) disinflationary monetary policies entail positive...

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...
