Economics
Basic macroeconomics, Indian economy, banking, budget and economic reforms.
Eight concepts of basic macroeconomics and the Indian economy as SSC and banking papers ask them: GDP against GNP, CPI against WPI, the national-income identity, fiscal deficit, Planning Commission to NITI Aayog, the 1991 LPG reforms, the three sectors, and RBI–SEBI–Finance Ministry roles. Prefer stable structure over a rotting 'current' rate — tables and pegs carry the night-before load.

1GDP counts borders; GNP counts nationals
Gross Domestic Product measures the value of all final goods and services produced within a country's borders in a year. Gross National Product starts from that idea and adds net factor income earned from abroad — income of nationals abroad minus income of foreigners earned domestically, in the standard exam gloss.
The word National in GNP is the cue: it tracks production by nationals, not only production inside the geographic border. Exams love swapping the two labels.
Figure. GDP counts production inside borders; GNP ties to nationals via net factor income from abroad.
| Measure | What it counts | Cue |
|---|---|---|
| GDP | Final goods and services produced within borders in a year | Domestic = territory |
| GNP | GDP idea plus net factor income from abroad | National = nationals' income link |
A factory owned by foreign investors produces goods inside India. For India's GDP versus GNP distinction as taught here, that output
- Counts in GDP because production is within India's borders; GNP adjusts further for net factor income from abroad
- Counts only in GNP and never in GDP, because the owners are foreign
- Counts in neither, because only government factories enter national income
GDP is territory-based: production inside borders counts. GNP then links to net factor income from abroad. Foreign ownership does not eject the output from GDP in this framing.
2Inflation: CPI retail, WPI wholesale
Inflation is a sustained rise in the general price level. In India, retail inflation is measured by the Consumer Price Index (CPI) and wholesale inflation by the Wholesale Price Index (WPI).
Monetary-policy questions in these notes tie the RBI's inflation target to CPI, not WPI — the source tip locks the framework band at 4% ± 2%. Prefer that structural CPI link over quoting a rotting 'current' print.
Figure. CPI is the retail index the RBI target uses; WPI tracks wholesale prices.
| Index | What it tracks | Exam cue |
|---|---|---|
| CPI | Retail / consumer prices | RBI inflation target uses CPI (4% ± 2% framework in source tip) |
| WPI | Wholesale / producer-level prices | Not the retail target index |
Retail inflation faced by end consumers is rising, and a monetary-policy stem asks which index India officially uses for that retail reading and for the RBI's target framing in these notes. The answer is
- WPI — because wholesale prices lead retail prices by definition in every stem
- CPI — Consumer Price Index for retail inflation; RBI targeting is tied to CPI here
- GDP deflator alone — because GDP and inflation are the same series
CPI measures retail/consumer inflation and is the index tied to the RBI target in these notes. WPI is wholesale. The GDP deflator is not the retail index named here.
3GDP = C + I + G + (X − M)
The national income identity used in these papers is GDP = C + I + G + (X - M), where C is consumption, I is investment, G is government spending, X is exports and M is imports. Net exports are (X - M).
Real GDP adjusts for inflation using a base-year price; nominal GDP is measured at current market prices. Lock the letter meanings and the real-versus-nominal fork — do not invent a numerical breakdown the source does not give.
Figure. Letter meanings only — bar heights are schematic, not a claimed GDP breakdown.
| Symbol / term | Meaning |
|---|---|
| C | Consumption |
| I | Investment |
| G | Government spending |
| X − M | Exports minus imports (net exports) |
| Real GDP | Inflation-adjusted (base-year prices) |
| Nominal GDP | Current market prices |
Two headlines report 'GDP up 10%' in a year of high inflation. Which reading matches the notes' real-versus-nominal distinction?
- Nominal GDP can rise with prices even when real output grows less; real GDP uses base-year prices
- Real GDP is always larger than nominal GDP by definition
- X − M is removed from real GDP but kept in nominal GDP
Nominal GDP uses current prices, so inflation can inflate the headline; real GDP holds prices at a base year. Real is not always larger, and net exports are part of the identity for both framings in this topic.
4Fiscal deficit = spending − non-borrowed receipts
Fiscal deficit equals total expenditure minus total receipts excluding borrowings. In words: how much the government must borrow to bridge the gap between what it spends and what it raises without borrowing.
That definition is the examinable load. Do not invent a current deficit ratio or budget number; those rot and the source does not fix them as evergreen pegs.
Figure. Fiscal deficit = total expenditure − receipts excluding borrowings.
| Piece | Role |
|---|---|
| Total expenditure | What the government spends |
| Total receipts (excl. borrowings) | Revenue and other non-borrowed inflows |
| Fiscal deficit | Expenditure − those receipts (borrowing need) |
While computing fiscal deficit, a student subtracts total receipts including this year's market borrowings from expenditure. What did they get wrong?
- Nothing — borrowings always count as receipts in the fiscal-deficit formula
- Borrowings must be excluded from the receipts side; the deficit is the gap that borrowings fill
- Expenditure must be excluded; only tax receipts enter the formula
Fiscal deficit uses receipts excluding borrowings. Including borrowings shrinks the measured gap by construction. Expenditure stays on the other side of the definition.
5Planning Commission (1950) → NITI Aayog (2015)
The Planning Commission was set up in 1950 and ran the Five-Year Plans. In 2015 it was replaced by NITI Aayog (National Institution for Transforming India), a policy think tank aimed at cooperative federalism.
Distinguish NITI Aayog from the Finance Commission (constitutional tax devolution), SEBI (securities regulation) and NABARD (rural credit). The year pair 1950 → 2015 is the transition peg.
Figure. Planning Commission (1950) → NITI Aayog (2015). Finance Commission and SEBI are lookalikes, not replacements.
| Body | Role to lock |
|---|---|
| Planning Commission (1950) | Five-Year Plans; replaced in 2015 |
| NITI Aayog (2015) | Policy think tank; cooperative federalism |
| Finance Commission | Constitutional body for tax devolution (not the replacement) |
| SEBI | Securities market regulator |
| NABARD | Rural / agricultural credit institution |
The Planning Commission of India was replaced in 2015 by which institution?
- Finance Commission — because it also advises on federal finance
- NITI Aayog — the policy think tank that succeeded the Planning Commission
- SEBI — because markets replaced planning
NITI Aayog replaced the Planning Commission in 2015. The Finance Commission and SEBI are different institutions with different mandates.
61991 LPG reforms
The 1991 reforms are remembered as LPG: Liberalisation, Privatisation and Globalisation. They were introduced under P. V. Narasimha Rao as Prime Minister and Dr. Manmohan Singh as Finance Minister, and they dismantled much of the License Raj.
Lock the three words, the year 1991, and the PM–FM pair. Do not invent GDP growth percentages or a list of every deregulated industry.
Figure. 1991 LPG under Rao (PM) and Manmohan Singh (FM): liberalisation, privatisation, globalisation.
| Fact | What to lock |
|---|---|
| Year | 1991 |
| LPG | Liberalisation, Privatisation, Globalisation |
| Prime Minister | P. V. Narasimha Rao |
| Finance Minister | Dr. Manmohan Singh |
| Thrust | Dismantling the License Raj |
In the standard 1991 LPG story used in these papers, Dr. Manmohan Singh's role was
- Prime Minister who coined LPG
- Finance Minister under P. V. Narasimha Rao
- RBI Governor who replaced the Planning Commission
Narasimha Rao was PM; Manmohan Singh was Finance Minister. NITI Aayog/Planning Commission is a different concept; he is not cast here as RBI Governor for 1991.
7Primary, secondary, tertiary
The primary sector covers agriculture and mining. The secondary sector covers manufacturing and industry. The tertiary sector covers services. In India's GDP mix as stated in the legacy notes, services contribute the largest share.
Classification questions name an activity and ask which sector; share questions remember that services lead, without inventing a precise percent.
Figure. Three sectors; services (tertiary) take the largest share of India’s GDP in the source note.
| Sector | Covers | India GDP note |
|---|---|---|
| Primary | Agriculture, mining | — |
| Secondary | Manufacturing / industry | — |
| Tertiary | Services | Largest share of India's GDP (as stated) |
A banking call-centre and a software export firm are grouped for a sector question. Which sector are they in, and which sector the notes say leads India's GDP?
- Secondary — and primary leads GDP
- Tertiary (services) — and services contribute the largest share to India's GDP
- Primary — because all private firms are primary by definition
Services are tertiary; the notes say services contribute the largest share to India's GDP. Call centres and software are not manufacturing (secondary) or agriculture/mining (primary).
8Inflation types; RBI, SEBI, Finance Ministry
Demand-pull inflation is too much money chasing too few goods. Cost-push inflation comes from rising input costs. Hyperinflation is an extremely rapid price rise. Keep those labels distinct from the CPI/WPI measurement concept.
Key institutions: the RBI is the monetary authority; SEBI regulates the securities market; the Finance Ministry handles fiscal policy and the Union Budget. Monetary versus fiscal is the fork exams exploit.
Figure. Inflation types above; RBI / SEBI / Finance Ministry below for policy levers.
| Item | What to lock |
|---|---|
| Demand-pull | Too much money chasing few goods |
| Cost-push | Rising input costs |
| Hyperinflation | Extremely rapid price rise |
| RBI | Monetary authority |
| SEBI | Securities market regulator |
| Finance Ministry | Fiscal policy and Union Budget |
Crude and other input costs jump and firms pass them into prices, while the Finance Ministry is preparing the Union Budget. Which inflation label fits the price story, and which body is the monetary authority rather than the budget author?
- Demand-pull; SEBI is the monetary authority
- Cost-push; RBI is the monetary authority (Finance Ministry handles the Budget)
- Hyperinflation by definition; NITI Aayog sets the policy repo
Rising input costs are cost-push. RBI is the monetary authority; the Finance Ministry handles fiscal policy and the Budget. SEBI is securities regulation; NITI Aayog is not the monetary-policy authority here.
Notes
- GDP and GNP: Gross Domestic Product measures the value of all final goods and services produced within a country's borders in a year, while Gross National Product adds net factor income earned from abroad.
- Inflation: A sustained rise in the general price level; in India retail inflation is measured by the Consumer Price Index (CPI) and wholesale inflation by the Wholesale Price Index (WPI).
- Planning in India: The Planning Commission (set up 1950) and its Five-Year Plans were replaced in 2015 by NITI Aayog (National Institution for Transforming India), a policy think tank.
- Economic reforms: The 1991 LPG reforms introduced Liberalisation, Privatisation and Globalisation under P. V. Narasimha Rao as PM and Dr. Manmohan Singh as Finance Minister, dismantling the License Raj.
- Sectors of the economy: The primary sector covers agriculture and mining, the secondary sector covers manufacturing/industry, and the tertiary sector covers services; services contribute the largest share to India's GDP.
Formulas
- National income identity: GDP = C + I + G + (X - M), where C is consumption, I is investment, G is government spending, X is exports and M is imports.
- Real vs nominal: Real GDP is GDP adjusted for inflation using a base-year price, while nominal GDP is measured at current market prices.
- Fiscal deficit: \text{Fiscal Deficit} = \text{Total Expenditure} - \text{Total Receipts (excluding borrowings)}.
- Types of inflation: Demand-pull inflation (too much money chasing few goods) and cost-push inflation (rising input costs); hyperinflation is extremely rapid price rise.
- Key institutions: RBI is the monetary authority, SEBI regulates the securities market, and the Finance Ministry handles fiscal policy and the Union Budget.
Exam traps & shortcuts
- GDP counts production 'within borders' while GNP is 'by nationals' - use the word 'National' in GNP to recall it includes income earned abroad.
- LPG reforms of 1991: Liberalisation, Privatisation, Globalisation - link them to Manmohan Singh as Finance Minister.
- CPI = 'Consumer/retail', WPI = 'Wholesale' - India targets CPI-based inflation for monetary policy.
- Planning Commission (1950) became NITI Aayog (2015) - remember '1950 to 2015' as the transition.
