Is there a long-term relationship between consumer, producer, commodity, and import price indexes? Analysis of price indexes cointegration in the EU member states
Original language description
There is a discussion how the consumer prices of food are formed. Whether they are determined by agricultural producers or commercial chains and their sales policy. The aim of the contribution is to analyse the cointegration between consumer, producer, commodity, and import price indexes in selected EU member states to find if there is a long-term relationship. Monthly data for 2005/01–2024/03 were taken from Eurostat. According to the ADF test, all time series were non-stationary at their level values, and almost all were stationary after the first differentiation with exception of consumer price index in Greece and Slovenia which couldn’t be included into further analysis just like Ireland, where the spurious regression occurred. Cointegration and long-term relationship between price indexes was found in Denmark, Austria, Germany, Bulgaria, Lithuania, and Hungary. The situation was unclear in the Netherlands and Portugal. The prices developed without any long-term equilibrium in other countries. EAAE Congress, Bonn, 26 - 29 August 2025.
