The Role of Labor Market Institutions in Shaping Euro Area Monetary Policy Transmission

We examine how labor market institutions shape monetary policy transmission in euro area countries. A theoretical model suggests that higher union density flattens the Phillips curve, amplifying output responses while dampening the inflation effects of monetary shocks. This is empirically confirmed using an interacted panelVAR. In contrast, benefit replacement rates and employment protection legislation have a limited impact. Our findings point to a structural, not cyclical, driver of monetary policy effectiveness, highlighting the importance of labor market features. In a monetary union, such heterogeneity can lead to inefficient inflation and output differentials across member states.
