      abstract = {Article refers to a method of forecasting wheat prices in  Poland, which was suggested in the literature. This
idea is  based on empirical observations. Authors observed that  there is a relationship between global prices of
wheat and  prices in Poland. The authors of this article have  identified a process ARIMA (0, 1, 1) as a stochastic
model  to describe the global prices of wheat. They also found a  correlation coefficients, which confirmed the
relationship  between the global and Polish prices. They forecasted  Polish wheat prices in the second quarter
of 2014 and the  ex-post errors. All calculations were performed using  GRETL.},
