The document discusses Austria's medium-term expenditure framework (MTEF) and use of reserves in budgeting. The MTEF sets binding multi-year expenditure ceilings for different budget rubrics and chapters. Reserves allow unused funds to be carried over, giving ministries flexibility while still requiring approval from the Ministry of Finance for large projects or legislative changes. This system has led to more efficient use of resources, considerable savings from accumulated reserves exceeding withdrawals, and improved prioritization within spending limits.
