The Fiscal Council, together with the European Commission (DG REFORM) and the Danish DREAM Institute (https://dreamgroup.dk/), held today an initial meeting within the project aided by the Technical Support Instrument (more information is available at: https://ec.europa.eu/info/overview-funding-programmes/technical-support-instrument-tsi_en) for developing a long-term public finance model. In addition to the aforementioned institutions, the meeting was attended by representatives of other Slovenian institutions dealing with topics of the project and providing information and data necessary for the development of the model. The model will be focused on social security systems and, on the completion of the project after 16 months, the model simulations will enable the Fiscal Council to prepare independent, unbiased and transparent opinions on long-term trends and adopted measures as well as to assess the long-term sustainability of social security systems and public finance in general.
