NOTION AND DETERMINANTS OF ECONOMIC SITUATION FLUCTUATIONS WITHIN POLISH NATIONAL ECONOMY DURING TRANSFORMATION PERIOD

Processes of fluctuations of economic situation have always been and still are intrinsic characteristic feature of highly developed market economies. Such fluctuations took also place in processes of economic growth in centrally planned systems. In countries where transformation processes are operated there also happen some determined changes in economic activity to be manifested in regular fluctuations of economic situation. General aim of the article is to formulate some hypotheses on notion itself and on factors determining processes of fluctuations of economic situation that have place in Poland during the nineties. The above mentioned fluctuations are a sequence o f successive phases of favourable and defavourable conjuncture being done that such a subsequence is relatively regular and involved with investments effectuated. When explaining a genesis of these oscillations one should first of all adopt endogenic models which are supposed to detect their reasons in internal factors operating within this system. Among determinants influencing a morphology of the oscillations we can distinguish as well short- and mid-term conjunctural factors as long-term structural changes
