National Income Identities (2)

🟢 Lite — Quick Review (1h–1d)

Rapid summary for last-minute revision before your exam.

This topic is Indian Economy: basic concepts, planning, reforms, and key sectors, drawn from UPPSC RO/ARO General Studies Paper I (weightage ~3%). The single most-tested cluster is national income accounting — students must distinguish GDP, GNP, NDP, and NNP, and know whether the figure is at factor cost or at market price. Two identity formulas recur every year: GNP = GDP + NFIA (Net Factor Income from Abroad) and NDP = GDP − Depreciation. The second cluster is fiscal deficits — memorise that Fiscal Deficit = Total Expenditure − Total Receipts (excluding borrowings), while Primary Deficit = Fiscal Deficit − Interest Payments. A one-line recall of LPG reforms 1991 (Liberalization, Privatization, Globalization) under Dr. Manmohan Singh, plus the shift from Planning Commission to NITI Aayog (2015), secures the static portion.

National Income Identities

India reports national accounts at current (nominal) prices and constant (real) prices, using 2011–12 as the base year. The four key aggregates are:

GDP (Gross Domestic Product) – value of all final goods and services produced within domestic territory.
GNP (Gross National Product) – GDP plus NFIA (income earned by Indians abroad minus income earned by foreigners in India).
NDP (Net Domestic Product) – GDP minus depreciation of fixed capital.
NNP (Net National Product) – GNP minus depreciation; at market price it approximates National Income (plus a small net indirect tax adjustment to reach factor cost).

The expenditure method identity GDP = C + I + G + (X − M) — consumption, investment, government spending, net exports — is the standard MCQ tested in Prelims.

Fiscal Deficit Family

The four deficits below must be memorised in a single table; the examiner frequently swaps terms to trap candidates.

Deficit	Formula	What it signals
Revenue Deficit	Revenue Expenditure − Revenue Receipts	Shortfall in current operations
Fiscal Deficit	Total Expenditure − Total Receipts (excl. borrowings)	Total borrowing requirement
Primary Deficit	Fiscal Deficit − Interest Payments	Borrowings for non-debt expenditure
Effective Revenue Deficit	Revenue Deficit − Grants for capital asset creation	Quality of revenue spending

Planning Architecture

The Planning Commission (1950–2014) was replaced by NITI Aayog (2015) under the executive resolution route. Unlike the Commission’s top-down fund allocation role, NITI Aayog is a policy think tank promoting cooperative federalism through state representation.

1991 Reforms (LPG)

Triggered by a BoP crisis in 1990–91 and IMF conditionality, Finance Minister Dr. Manmohan Singh (under PM P.V. Narasimha Rao) dismantled the License Raj, devalued the rupee, opened trade, and privatised PSUs. The triad — Liberalisation, Privatisation, Globalisation — is a compulsory descriptive question in Mains.

Sectors & Key Schemes

India’s GDP composition is dominated by services (~50%), followed by industry, then agriculture. The UPSC-relevant flagship schemes are MGNREGA, PM-KISAN, Make in India, Atmanirbhar Bharat, GST (2017), and DBT for subsidy transfer.

Banking & Monetary Policy

The RBI is the apex monetary authority. The four primary policy tools — Bank Rate, Repo Rate, Reverse Repo Rate, and MSF — anchor liquidity, while CRR (Cash Reserve Ratio) and SLR (Statutory Liquidity Ratio) dictate credit creation. The money multiplier (m = 1/RR) explains how a 1% CRR cut expands deposits. Be alert: an examiner may ask why CRR change is preferred over Bank Rate for high-impact, short-term liquidity absorption.

Price Indices & Inflation

WPI (Wholesale Price Index) tracks wholesale transactions and is published by the Office of Economic Adviser; CPI (Consumer Price Index) measures retail inflation faced by households and is calculated by NSO, MoSPI. Since 2014, RBI uses CPI (combined) as the formal inflation target under flexible inflation targeting (4% ± 2%) — a direct Prelims trap. GDP Deflator = (Nominal/Real) × 100 captures economy-wide price movement.

Banking Health: NPAs

Non-Performing Assets are advances where interest or principal remains overdue for 90 days or more. The IBC (Insolvency and Bankruptcy Code, 2016) created a time-bound recovery mechanism; Punjab National Bank (2018 fraud) and the YES Bank (2020) restructuring are classic case-study hooks.

External Sector

The Balance of Payments has two heads: Current Account (trade in goods/services, invisibles) and Capital Account (FDI, FPI, external borrowings). Current Account Deficit (CAD) is sustainable below 3% of GDP; the 2012 taper-crisis episode (CAD touched 4.8%) is a frequent Mains question.

Common Mistakes

Confusing GDP at factor cost (now discontinued but still asked) with GVA introduced in 2015.
Treating Fiscal Deficit as borrowing from RBI — it is total government borrowing across the system.
Saying NITI Aayog replaced the Finance Commission — it replaced the Planning Commission.

Practice Prompts

Distinguish between Revenue Deficit, Fiscal Deficit, and Primary Deficit. Why is Effective Revenue Deficit considered a better measure of revenue quality? (150 words)
“The 1991 reforms were a structural break from the 1956–1989 development model.” Discuss with reference to LPG and the role of the BoP crisis. (250 words)
