Introduction to Macroeconomics and National Income Accounting
What this domain tests
Introduction to Macroeconomics and National Income Accounting asks you to move from individual markets to economy-wide aggregates and calculate them correctly. RBSE VU questions typically test the circular flow, the GDP/GNP/NNP family, the three measurement methods, and real versus nominal income.
Core rules
- Circular flow: households supply factors and demand goods; firms demand factors and supply goods. With government and the foreign sector, leakages (saving, taxes, imports) and injections (investment, government spending, exports) enter.
- GDP at market price is the money value of final goods and services produced within domestic territory in a year. Intermediate goods and transfer payments are excluded; second-hand sales are excluded except dealer commission.
- GNP = GDP + net factor income from abroad (NFIA). NNP = GNP − depreciation. National income at factor cost = NNP at market price − net indirect taxes.
- Three methods: product/value added, income, and expenditure. They should give the same total; differences appear as statistical discrepancy.
- Real GDP uses constant prices; nominal GDP uses current prices. GDP deflator = (nominal/real) × 100.
Worked example
GDP at market price = 5,000; depreciation = 400; NFIA = −100; net indirect taxes = 300. GNP at MP = 5,000 + (−100) = 4,900. NNP at MP = 4,900 − 400 = 4,500. National income (NNP at FC) = 4,500 − 300 = 4,200. Reasoning: add NFIA once, subtract depreciation to reach net, then remove indirect taxes to reach factor cost.
Traps
Including intermediate goods or transfers such as pensions in GDP; adding NFIA with the wrong sign; confusing NNP at MP with national income at FC; treating inflation as real growth; and forgetting that GDP covers domestic territory while GNP covers residents.
