The document discusses medium-term expenditure frameworks (MTEFs) and their advantages, including providing greater certainty in planning, facilitating top-down budgeting, and making budget gimmickry harder. It defines MTEFs as identifying resource availability and current spending needs over a multi-year period, usually 3-5 years, to determine future resource allocations. Baseline projections are also discussed as estimating spending if current policies remain unchanged. However, the document notes that few countries implement MTEFs well due to issues like lack of integration into the budget process and lack of robust costings and up-to-date baselines.
