Quelle prise en compte des caractéristiques nationales dans les mesures macroprudentielles en zone euro ?

This article examines the impact of cross-border lending on the implementation of macroprudential measures in the Euro Area. The goal is to evaluate - regardless of the current institutional organization - what relative weight should be allocated to federal and national considerations. The analysis relies on an estimated two-country dynamic stochastic general equilibrium (DSGE) model, based on the financial accelerator mechanism. This model is estimated using Bayesian techniques on European data adopting the coreperiphery dichotomy. Our results underline that divergences of real and financial cycles between the two regions of the monetary union are driven by both the regional heterogeneity of structural parameters and shocks which are larger in periphery. Regarding the implementation of financial stability measures, the heterogeneous treatment between countries leads to tighter macroprudential measures for periphery, but this affects differently regional macroeconomic performances. Finally, a counterfactual analysis studying the response of output and investment during the financial crisis episode reveals that peripheral countries strongly benefited from the implementation of macroprudential measures at the expense of core countries which experienced a deterioration of their situation.
