Abstract

Różnorodność szoków oddziałujących na inflację cen w Polsce sprawia, że rozstrzygnięcie o roli każdego z nich nie jest możliwe bez wykorzystania właściwych metod analizy ilościowej. W artykule przedstawiono ekonometryczny makromodel cen i płac, w którym wyeksponowano bezpośrednie oddziaływanie na inflację szoków podażowych transmitowanych z rynków surowców energetycznych oraz oddziaływanie tych szoków na sprzężenie płacowo-cenowe. Ze względu na tajność danych o cenach i wolumenów importu gazu ziemnego z Rosji do Polski zaproponowano metodę oszacowania deflatora importu gazu ziemnego na podstawie danych o pozostałych głównych surowcach energetycznych (ropa naftowa i węgiel). Model umożliwia ocenę, w jakim stopniu ceny krajowe (CPI) zależą od tendencji na rynkach światowych (w tym od cen surowców energetycznych), a w jakim stopniu od cen krajowych; możliwe jest oszacowanie wpływu polityki fiskalnej na kształtowanie się cen. Równania modelu są konstruowane przy wykorzystaniu metod kointegracyjnych dla zdezagregowanych indeksów cen konsumenta i cen importu. Własności systemu 19 równań są badane przy wykorzystaniu analizy mnożnikowej. Zaprezentowano wyniki symulacji, w której założono niepodejmowanie działań antykryzysowych w okresie pandemii COVID-19. Uzyskane wyniki wskazują na istotną rolę polityki fiskalnej w kształtowaniu cen.
