The paper presents the results of the first application of cyclical analysis to economic activity in Serbia. The analysis refers to the period 2001-07, which marked the start of democratic and economic reforms, since short term fluctuations in economic activity prior to 2001 were the result of various exogenous shocks like hyperinflation, wars and international economic sanctions. In the post-reform period, the Serbian economy exhibits characteristics of a small, open, marketoriented economy. Economic activity shows an upward trend, and with special regard to growth dynamics and their cyclical properties, cyclical analysis is relevant. In analysing cyclical fluctuations in economic activity, a deviation-from-trend approach is applied. For dating turning points in economic activity, the monthly gross domestic product (GDP) is used since the coincident properties of the index of industrial production could not be statistically verified for Serbia as there were a small number of quarterly observations available for GDP.
