Do Unit Labor Cost Drive Inflation in the Euro Area?
The purpose of this study is to analyze the relationship between unit labor costs and inflation. We estimate an optimal price path model based on a New Keynesian Phillips Curve for eleven euro area countries individually, under the assumption that unit labor costs are proportional to marginal costs. We seek such a model which minimizes the distance between fitted and actual price level fluctuations, with parameters that satisfy theoretical restrictions. The econometric methodology used is a two-step approach method. Estimates show that in eight of the eleven euro area countries there is a plausible relationship between unit labor costs and price level dynamics. The average time needed to adjust prices in line with movements in unit labor costs is estimated to be around eight months. In the case of Slovakia the results indicate rather flexible prices.
