Abstract

W opracowaniu przedstawiono syntetyczny wskaźnik aktywności gospodarczej w Polsce (barometr koniunktury), zbudowany na podstawie danych ankietowych Instytutu Rozwoju Gospodarczego SGH i Instytutu Transportu Samochodowego. Do oszacowania barometru koniunktury zastosowano podejście wykorzystujące modele czynnikowe, w tym dynamiczne. Estymacje przeprowadzono trzema alternatywnymi metodami. Oszacowany na ich podstawie nieobserwowalny czynnik potraktowano jako syntetyczny wskaźnik aktywności gospodarczej. Dla odniesienia analizą objęto również barometr koniunktury IRG SGH, konstruowany wg podejścia tradycyjnego. W świetle przeprowadzonych badań zastosowanie modeli czynnikowych do estymacji wskaźnika aktywności gospodarczej opartego na danych ankietowych nieznacznie poprawia użyteczność tego typu wskaźników w monitorowaniu wahań zmiennej referencyjnej (PKB). Prezentowane podejście wymaga dalszych analiz, które pomogą poprawić jakość diagnostyczną barometru koniunktury. [This paper presents a new business cycle indicator of the Polish economy based on survey data from the Research Institute for Economic Development and the Motor Transport Institute. In order to deal with large number of series the factor model approach (FM) is used. Models are estimated using three different methods. The unobserved factor from these models represents a composite indicator. It is compared with the RIED business cycle indicator. The results suggest that the former performs only slightly better than the latter as far as their ability to indicate changes in GDP is concerned. Further research is needed to improve qualities of the proposed business cycle indocator.]
