It includes the part where the methods and approaches used by both national and international institutions, as well as in scientific studies, are characterized. It also presents the characteristics of the analysis of the current fiscal sustainability monitoring in Poland carried out by the European Commission, International Monetary Fund and the Ministry of Finance, based on the standardized approach.
