Cet article propose une extension du cadre de travail théorique proposée par Bilbiie, Ghironi et Melitz [2007] en économie ouverte afin d'étudier les effets de la politique monétaire sur marges intensives et extensives sur l'activité économique. Deux régimes de politique monétaire sont...

This paper shows that in a monetary union the interest rate rule of the Central Bank should react to the in°ation rate of the Harmonized Index of Consumption Price (HICP) rather than to the inflation rate of the Welfare-Based Consumption Price (WBCP). In a two{country general equilibrium model...

This paper investigates the impact of alternative monetary policy regimes on the creation of new varieties in open economies. Using a dynamic two-country model incorporating nominal rigidities, international trade and firm entries we compare an independent monetary policy regime to a monetary...

This paper evaluates the welfare gains arising from a deeper trade integration in the European Monetary Union. To do this, the European Monetary Union is represented in a realistic way by an intertemporal general equilibrium model with incomplete financial markets, sticky prices and home bias in...

Cet article étudie la manière dont la politique monétaire doit être conduite en économie ouverte lorsque l'on prend en compte son influence sur la marge extensive de l'activité. Dans un modèle à deux pays, on montre que, contrairement aux résultats obtenus par Bilbiie, Ghironi et...

Using a two country DGSE combining nominal rigidities and financial frictions, we show that the persistence of output and inflation asymmetries observed since 1999 in an increasingly integrated EMU is not necessarily puzzling. Only the integration of final goods markets unambiguously leads to a...

How to explain rising income and wealth inequality? We build an original heterogeneous-agent model with three key features: (i) an explicit link between firm's market power and top income shares, (ii) a granular representation of the tax and transfer system, and (iii) three assets with...

In this paper we study jointly optimal ¯scal and monetary policies in a small open economy framework with capital and sticky prices. We consider the case of distor- tionary taxes on labor and capital, and no public debt. As in a closed economy set{up, in the steady state, the optimal in°ation...
