The recent financial crisis has stimulated theoretical and empirical research on the propagation mechanisms underlying business cycles, in particular on the role of financial frictions. Many issues concerning the interactions between banking and monetary policy forced policy makers to rede.ne...

We assess the role of national fiscal policies, as automatic stabilizers, within a monetary union. We use a two-country New Keynesian DGE model which incorporates non-Ricardian consumers (as in Galì et al. 2004) and a home bias in the composition of national consumption bundles. We find that...

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...

This paper provides optimal labor and dividend income taxation in a general equilibrium model with oligopolistic competition and endogenous firms' entry. In the long run the optimal dividend income tax corrects for inefficient entry. The dividend income tax depends on the form of competition and...

It has been argued that rule of thumb consumers substantially alter the determinacy properties of simple interest rate rules and the dynamics of an otherwise standard New-keynesian model. In this paper we show that nominal wage stickiness helps re-establishing standard results. Key findings are...

We introduce Cournot competition and endogenous entry in an otherwise neoclassical macroeconomic framework. First, we develop a model with exogenous savings à la Solow describing the dynamic path of business creation. Then, we develop a model à la Ramsey describing the dynamic interaction of...

We assess the role of national fiscal policies, as automatic stabilizers, within a monetary union. We use a two-country New Keynesian DSGE model, incorporating non-Ricardian consumers and a home bias in national consumption. Fiscal policy directly stabilizes non-Ricardian agents' consumption. By...

We study the design of monetary policy in an economy characterized by staggered wage and price contracts together with limited asset market participation (LAMP). Contrary to previous results, we find that once nominal wage stickiness, an incontrovertible empirical fact, is considered: i) the...

We study the impact of a General Purpose Technology that changes the cost structure turning fixed costs into variable ones in most sectors. A major recent example is cloud computing, whose adoption allows firms to avoid large up-front costs in IT and to rent computing capability online. We study...
