Fundamental Economic Concepts Every Aspirant Must Know
GDP (Gross Domestic Product): The total monetary value of all goods and services produced within a country's borders in a specific time period. India's nominal GDP is ~$3.7 trillion (2024), making it the world's 5th largest economy.
GNP (Gross National Product): GDP + income earned by residents abroad − income earned by foreigners within the country. GNP measures the output of a country's residents regardless of location.
GDP at Constant Prices (Real GDP): Adjusted for inflation; used to measure actual growth.
GDP at Current Prices (Nominal GDP): Measured at prevailing market prices; includes inflation effect.
GDP per capita: Total GDP divided by population. India's GDP per capita is ~$2,600 (2024) — a key measure of standard of living.
National Income = GDP − Depreciation (Capital Consumption) + Net Factor Income from Abroad
Inflation: A sustained increase in the general price level.
- CPI (Consumer Price Index): Measures inflation from the consumer's perspective. RBI targets CPI inflation at 4% (with a band of ±2%).
- WPI (Wholesale Price Index): Measures inflation at the wholesale/producer level.
- Stagflation: Simultaneous high inflation + high unemployment + slow economic growth (worst economic scenario).
Fiscal Deficit: When government's total expenditure exceeds its total receipts excluding borrowings. A high fiscal deficit can lead to inflation and crowding out of private investment.
Current Account Deficit (CAD): When imports of goods and services exceed exports. India typically runs a current account deficit because it imports more oil than it exports.
Reserve Bank of India (RBI): Functions and Monetary Policy Tools
The Reserve Bank of India was established on 1 April 1935 under the Reserve Bank of India Act, 1934. It was nationalised on 1 January 1949. Headquarters: Mumbai.
Functions of RBI:
1. Issue of currency notes (all notes except ₹1 coin, which is issued by the Ministry of Finance)
2. Banker to the Government (manages government accounts and public debt)
3. Banker's Bank (provides credit to commercial banks, acts as lender of last resort)
4. Controller of credit and monetary policy
5. Manager of foreign exchange reserves
6. Supervision and regulation of the banking system
Key Monetary Policy Tools:
| Tool | Definition | Current Rate (approx. 2024) |
|---|---|---|
| Repo Rate | Rate at which RBI lends short-term funds to commercial banks | 6.5% |
| Reverse Repo Rate | Rate at which RBI borrows from commercial banks | 3.35% |
| CRR (Cash Reserve Ratio) | Percentage of deposits banks must keep with RBI (no interest) | 4% |
| SLR (Statutory Liquidity Ratio) | Percentage of deposits banks must invest in approved securities | 18% |
| Bank Rate | Rate for medium/long-term borrowing from RBI | 6.75% |
| MSF (Marginal Standing Facility) | Emergency borrowing by banks overnight | 6.75% |
Exam tip: When RBI raises the repo rate, borrowing becomes costlier → money supply decreases → inflation is controlled (but growth may slow). This is a contractionary monetary policy.
Monetary Policy Committee (MPC): A 6-member committee (3 from RBI + 3 external members appointed by Government) that meets every 2 months to decide the repo rate. Governor of RBI chairs the MPC.
India's Planning and Economic History
Five Year Plans:
India followed Five Year Plans from 1951 to 2017, modelled on the USSR's planning system. The Planning Commission of India (set up in 1950) administered them. In 2015, the Planning Commission was replaced by NITI Aayog (National Institution for Transforming India).
| Plan | Period | Key Focus |
|---|---|---|
| 1st Plan | 1951–56 | Agriculture, irrigation, power |
| 2nd Plan | 1956–61 | Heavy industries (Mahalanobis Model) |
| 3rd Plan | 1961–66 | Self-reliance, agriculture + industry |
| 4th Plan | 1969–74 | Growth with stability |
| 5th Plan | 1974–79 | Poverty alleviation, self-reliance; terminated early |
| 6th Plan | 1980–85 | Poverty reduction, economic growth |
| 7th Plan | 1985–90 | Food, work, productivity |
| 8th Plan | 1992–97 | Human development, liberalisation (post-1991 reforms) |
| 9th Plan | 1997–02 | Equitable distribution with growth |
| 10th Plan | 2002–07 | Reducing poverty by half |
| 11th Plan | 2007–12 | "Faster and More Inclusive Growth" |
| 12th Plan | 2012–17 | "Faster, Sustainable, and More Inclusive Growth" |
Economic Reforms of 1991: When India faced a balance of payments crisis (foreign exchange reserves could cover only 2 weeks of imports), PM Narasimha Rao and Finance Minister Dr. Manmohan Singh introduced the LPG reforms — Liberalisation, Privatisation, and Globalisation. India pledged its gold to IMF to avoid default. These reforms transformed India from a closed, licence-controlled economy (Licence Raj) to a market economy.
NITI Aayog (since 2015): Policy think tank; formulates 15-year vision, 7-year strategies, and 3-year action plans. Unlike the Planning Commission, it does NOT allocate funds to states.
