Une analyse de la convergence des ratios de sacrifice en Europe.

This paper assesses the degree of homogeneity of macroeconomic frameworks of European countries by testing the presence or absence of a mechanism for convergence of sacrifice ratios within different groups of European countries. For this, a two-step statistical procedure is used. The first step estimates the trajectory of the sacrifice ratios of seventeen European countries using rolling regressions. The second step then tests the presence of a trend to reduce the dispersion of the sacrifice ratios between these countries. The tests conclude in favor of the presence of a phenomenon of convergence of sacrifice ratios between the late '80s and the end of the sample within the two groups of countries: European countries characterized by decentralized wage bargaining and countries belonging to the core group identified by Bayoumi-Eichengreen. Other groups of European countries are by cons show a lack of convergence or divergence of sacrifice ratios.
