The authors of the article examined the impact of exchange quotations of indexes WIG, WIG20 and
WIG-food on prices of hog livestock in Poland. Based on the collected data was constructed an econometric
model, which explains the evolution of the monthly prices of the hog livestock in Poland in the period from
January 2004 to December 2015 depending on the WIG20 index quotes. This model of the linear regression
has been estimated, verified substantially and statistically and next used to calculate point forecasts for all
months of 2016. Forecasts errors have also been calculated.
The authors of the article examined the linear correlation between indexes WIG20 and WIG-food
and prices of rape in Poland. Based on the collected data to be constructed econometric model, in which
the quarterly price of rape in Poland since 2004 to 2016, depend on the explanatory variables: time and
exchange quotations of index WIG-food. This model has been estimated, validated statistically, and then
