Prognozowanie cen na przykładzie sprzedaży dorszy w Polsce w latach 2004–2013

In the modern economy, market entities are trying to reduce risk and uncertainty in their actions. The most important element is the price and the need for information on future prices is crucial for efficient business. Forecasting is a form of predicting the future. The aim of the study was to determine if decomposition of the time series allows to generate reliable and short-term price forecasts. The indicators were the first-sale prices of Baltic cod, which were landed in Polish ports by Polish fishing operators in 2004–2013. The analysis showed that random fluctuations have the greatest impact on prices, and thus, the utilised forecast model is not a good method for predicting these prices.
