What is economics?

Economics is the study of how individuals, businesses and governments use scarce resources to satisfy unlimited wants. Its central problem is scarcity and choice. Adam Smith (The Wealth of Nations, 1776) is the "father of economics"; Alfred Marshall defined it as the study of man in the ordinary business of life; Lionel Robbins as the science of scarcity; J. M. Keynes (General Theory, 1936) founded modern macroeconomics; Paul Samuelson wrote a famous textbook.

• Microeconomics studies individual units — consumers, firms, markets, prices. Macroeconomics studies the economy as a whole — national income, inflation, employment, growth.
• Factors of production: land (rent), labour (wages), capital (interest), entrepreneurship/organisation (profit).
• Basic economic problems of every society: what to produce, how to produce and for whom to produce.
• Production Possibility Frontier (PPF) shows the maximum combinations of two goods possible with given resources; the opportunity cost is the value of the next-best alternative given up.

Economic sectors

• Public sector (owned by the government), private sector, joint sector, and the cooperative sector. Organised (registered, regulated) vs unorganised (informal) sector — the unorganised sector employs the large majority of workers.
• Structure of the Indian economy: the services sector contributes over half of the Gross Value Added (GVA) (about 55 %), industry about 25–30 % and agriculture about 15–18 %, while agriculture still employs the largest share of the workforce. (Approximate; check the latest figures.)

Types of economic systems

India adopted a mixed economy with planning after independence (Industrial Policy Resolution 1948 and 1956 — the "Economic Constitution of India"), with the public sector on the "commanding heights", and moved towards a market-oriented model after 1991.

National income concepts

National income is the total value of all final goods and services produced by a country in a year.

• Gross = including depreciation; Net = excluding it. Domestic = within the territory; National = by the nationals.
• At market prices includes indirect taxes less subsidies; at factor cost excludes them. Since 2015 India measures growth by GDP at market prices (and GVA at basic prices).
• Nominal (current-price) GDP is measured at the prices of the current year; real (constant-price) GDP at base-year prices, removing the effect of inflation. GDP deflator = (nominal GDP ÷ real GDP) × 100.
• Base year: the current series has the base 2011–12 (introduced in 2015); a new series with base year 2022–23 was to be released by MoSPI in 2026 (check the current status).
• Statistical bodies: MoSPI and the National Statistical Office (NSO), which release the National Accounts (quarterly and annual GDP estimates), the Index of Industrial Production (IIP) and Consumer Price Index (CPI); the Central Statistics Office merged into the NSO in 2019; the National Statistical Commission (2006).

Methods of measuring national income

1. Product (value-added) method: sum of the value added in each sector. Avoids double counting.
2. Income method: sum of factor incomes — wages, rent, interest, profit and mixed income.
3. Expenditure method: $\text{GDP}=C+I+G+(X-M)$ — consumption, investment, government spending, and net exports.

In India, the product method is used for agriculture, industry, and the income method for services; the expenditure method is used to cross-check.

Size of the Indian economy (indicative)

India is the fifth-largest economy by nominal GDP in recent years (about 3.5–4 trillion US dollars, having passed the UK in 2022 and then approaching Japan and Germany) and the third-largest by purchasing power parity (PPP). It has been one of the fastest-growing major economies (growth of about 6–8 % in recent years). Per capita income remains in the lower-middle income category. The government's goal is "Viksit Bharat" by 2047 (a developed nation) and a 5 trillion US dollar economy. (Check the latest rank and value.)

A note on figures. Policy rates (repo, CRR, SLR) and inflation targets are revised by the RBI from time to time. Use the latest Monetary Policy Statement for current values.

Money

Money is anything generally accepted as a medium of exchange, a measure of value, a store of value and a standard of deferred payment. Barter suffers from the double coincidence of wants.

• Forms: commodity money (gold, silver), fiat money (currency notes and coins declared legal tender), bank money (deposits, cheques), digital money (UPI, cards, wallets, CBDC).
• Legal tender: unlimited for notes; limited for coins (e.g., coins up to certain limits). ₹1 notes and coins are issued by the Government of India (Ministry of Finance); all other notes (₹2 to ₹500) are issued by the RBI (the Governor's signature is on the note; the Finance Secretary's signature on the ₹1 note). Minimum Reserve System (1956) for the note issue: the RBI must hold gold and foreign securities worth ₹200 crore, of which gold at least ₹115 crore.
• Security Printing: notes are printed at Nashik, Dewas, Mysuru, Salboni (Note Printing Presses); coins are minted at Mumbai, Hyderabad, Kolkata, Noida.
• Demonetisation (8 November 2016) withdrew ₹500 and ₹1000 notes; a new ₹2000 note was introduced (withdrawn from circulation in 2023).

Money supply

The RBI publishes four measures:

Money multiplier = M3 / M0.

Banking structure in India

• History: the first Indian bank was the Bank of Hindustan (1770); the Presidency Banks (Bengal, Bombay, Madras) merged into the Imperial Bank of India (1921), which became the State Bank of India (1955).

Nationalisation: 19 July 1969 (14 banks with deposits above ₹50 crore — Indira Gandhi) and 15 April 1980 (6 more).
• Banking Regulation Act 1949 (now the Banking Laws Amendment); the RBI Act 1934.
• Deposit insurance: DICGC (a subsidiary of the RBI) insures deposits up to ₹5 lakh per depositor per bank.
• Priority Sector Lending (PSL): 40 % of adjusted net bank credit — agriculture, MSMEs, education, housing, weaker sections. Lead Bank Scheme (district level); Kisan Credit Card (1998); Jan Dhan Yojana (2014) for financial inclusion.
