Analiza zbieżności cykli cenowych rynku ropy naftowej z cyklami koniunkturalnymi gospodarek Europy Środkowo-Wschodniej

The main purpose of the paper is to study the degree to which the Brent crude oil price cycle is correlated and synchronized with business cycle in a set of chosen Central Eastern European (CEE) economies. To indentify the oil price cycle and business cycles for chosen individual countries the Markov-switching autoregressive model (MS-AR) is used. The identification of the smoothed probabilities of being in regime 1 and regime 2 enables the calculation of correlation coefficients between those probabilities and the concordance index to evaluate the synchronization of oil price cycle and business cycles for the CEE economies.
