The world oil price is an exogenous as well as key component and factor influencing domestic prices (especially transportation). The question is: how the oil price influences producer and consumer prices. We focus on a short- and long-term relationship between the domestic prices and oil price (expressed in Polish zloty). We use Vector Error Correction Models, with cost-based specification, i.e. including additionally wages and euro-zloty exchange rate. The degree of estimated long-term pass-through oil prices to producer and consumer prices is 0,15 and 0,05, respectively. Both producer and consumer prices have comparable size of short-term reaction to an oil price shock, but the producer price reaction is more prolonged.

The purpose of the paper is to estimate parameters of the New Keynesian Philips Curve, NKPC, for Poland by means of monthly data. The so called hybrid NKPC that is taken in the investigation extends the NKPC by adaptive expectations, which allows for implementation of the theoretical New Keynesian model to empirical analyses. Starting with theoretical specification, the authors provide the reader with statistical data and the estimation method used in the research, which is followed by presentation of empirical outcomes and conclusions.
