Abstract

The paper attempts to study the influences of the quarterly changes in the international oil price upon certain macroeconomic indicators and upon the GDP, using the principal components analysis. It also analyzes the indirect impact of a change in oil prices – through all the other indicators – and also the direct one – through channels not reflected by the selected indicators and assuming they stay unchanged. The method revealed which of the considered components were more or less influenced by the changes in the oil price, and allowed for the quantification of the impact of the possible oil price shocks upon each of the considered variables, and, implicitly, upon the GDP, in the same interval within such a shock has occurred.
