This paper questions the impact of trade integration on business cycle synchronization in the EMU by distinguishing increase of existing trade flows (the intensive margin) and creation of new trade flows (the extensive margin). Using a DSGE model, we find that synchronization is weakened when...

RESUME :Au cours des 15 dernières années, l'intégration financière au sein de la zone euro s'est effectuée enpartie à travers le développement de flux bancaires transfrontaliers. Cet article étudie lesconséquences macroéconomiques des prêts transfrontaliers à l'aide d'un modèle DSGE...

This paper describes a DSGE model where the extensive margin of activity —the number of varieties available for consumption—, depends on micro-founded decisions of entry and exit in the goods market. Both the extended model and a more conventional version have been estimated with US data...

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...

Introducing both endogenous firm entry and a requirement for external finance in a general-equilibrium model leads to three main results. First, the financial constraint has contractionary effects on both equity investment and the labor supply as they are inversely related to the marginal...
