Supporting purchasing decisions with time series analysis – the case of a plastics company
Our empirical paper uses time series analysis with the FM-OLS estimator to analyse the significant determinants of purchasing prices of a Hungary-based plastics company. Beyond using crude oil prices, we also involve industry-specific indices in the analyses. We use bivariate vector error correction models to support their long-term usefulness in managerial inference.
