Public Finance and Development Planning: Budget, Taxation and Plan Architecture
Public finance fundamentals
Know the budget cycle: formulation, approval, execution, audit and oversight. Understand revenue versus capital expenditure, the Annual Development Programme, and the distinction between the revenue budget and the development budget. Master the concepts of direct and indirect taxation, tax buoyancy, tax-to-GDP ratio, VAT, and the difference between progressive and regressive taxes.
Deficit and debt
Understand how a fiscal deficit is financed: domestic borrowing, external borrowing, and seigniorage. Know the concept of debt sustainability, the debt-to-GDP ratio, and the crowding-out effect. Distinguish grants from loans and concessional from commercial borrowing.
Development planning
Learn the history of planning: the Five-Year Plans and the shift to the Perspective Plan and the Five-Year Plan framework, plus the role of the Planning Commission and the National Economic Council. Understand the concepts of project appraisal, cost-benefit analysis, and the distinction between a plan and a project. Know the Sustainable Development Goals and how they map to national plans.
Traps
Do not confuse the ADP with the entire budget. Do not treat all external assistance as grants. Do not equate a high tax rate with high revenue; the base matters. Remember that the Comptroller and Auditor General audits, while Parliament's Public Accounts Committee oversees.
Worked rule of thumb
For any public finance question, use the 'three questions' test: Where does the money come from (revenue mix)? Where does it go (expenditure priority)? Who checks it (audit and oversight)? This frames answers comprehensively.
Exam technique
Use ratios rather than absolute figures where uncertain. Link planning to outcomes, and always mention accountability institutions.
