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,...

We study optimal 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...

We derive a New Keynesian Phillips Curve under Calvo staggered pricing and price competition. Firms strategic interactions induce price adjusters to change their prices less when there are more firms that do not adjust. This reduces the slope of the Phillips curve and generates an additional...

We reconsider the New Keynesian model with staggered price setting when each market is characterized by a small number of firms competing in prices à la Bertrand rather than a continuum of isolated monopolists. Price adjusters change their prices less when there are more firms that do not...

We derive a New Keynesian Phillips Curve under Calvo staggered pricing and price competition. Firms strategic interactions induce price adjusters to change their prices less when there are more firms that do not adjust. This reduces the slope of the Phillips curve and generates an additional...

We study the effects of real uncertainty on long-run growth under different Taylor-type rules. We fi…nd a non-negligible relationship between real uncertainty and growth, which depends on the source of real uncertainty as well as the type of the Taylor rule considered. Importantly, when...

I consider a NK-DSGE model with endogenous firms' exit and entry together with a monopolistic competitive banking sector, where defaulting firms do not repay loans to banks. I show that the exit margin is an important shock transmission channel. It implies: i) an endogenous countercyclical...

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...

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...
