摘要：This paper presents the impact of changes in prices
of agricultural products on changes in retail prices of agrifood
products. The basis for the study was data on changes
in prices of milk, wheat, pork and poultry and derived products
in Poland in 2007–2016. A relationship was discovered
between the variables, on one side, and lags between the examined
time series, on the other. The cross-spectral analysis
was used to study the periodicity of changes and lags between
time series.
