Regionalne krzywe Phillipsa w Polsce a efektywność polityki pieniężnej
Regional Phillips Curves in Poland and the Effectiveness of Monetary Policy

Summary/Abstract: The aim of the paper is to show the relationship between the unemployment rate at regional level and the aggregate inflation at national level. The theoretical part of the paper discusses various concepts of the short-term Phillips curve and their implications for monetary policy. The empirical part brings an attempt to estimate non-linear shortterm Phillips curves for Polish vojevodships. The results of the estimation based on panel data, as well as estimations of the curves for individual vojevodships, suggest the existence of a concave dependence between inflation and unemployment gap in most vojevodships. According to the Lipsey concept, this means that the aggregate Phillips curve in Poland can move upwards in the periods marked by regional convergence while regional divergence may shift it downwards. The results of this research have significant implications for the effectiveness of national monetary policy.
