A multi – speed Europe, and the peripherality of Poland

Summary/Abstract: In recent years, research on the synchronization of business cycles in economies has been undertaken more than once. This is a desirable phenomenon especially for the European Union. The aim of the article is to verify selected macroeconomic indicators that characterize the economies of countries belonging to the European Union in relation to Poland, thus presenting convergence of dynamic cycles of changes in socio-economic sphere indicators: inflation rate, unemployment rate, short-term interest rates, and GDP. For this purpose, a cross-spectral analysis was used which allows us to show the occurring fluctuations of different lengths, as well as to compare the strength of the relation of changes between selected indicators. According to the conducted analyses, it was noted that the Polish economy (in the perspective of long-term changes) is a determinant of changes for highly developed countries.
