Foundation Static Core Zero prior knowledge Concepts & Terms

How to use this primer

This primer is your foundation layer — read it first, before the three Mains-level GS3 economy notes. Its goal is simple: when you later encounter "fiscal deficit", "GDP", "repo rate" or "inclusive growth", you already know what those words mean. Every new term is shown in bold blue and defined in plain English, usually with a real-life analogy. There is no need to memorise data here — focus on understanding the ideas. The yellow boxes summarise; the A–Z glossary at the end is your quick look-up. Once these click, the advanced notes will feel easy.

Section 1

What is an economy?

1.1 — Economy & economics: the starting point

The core idea

An economy is simply the system by which people produce, exchange and use goods and services to satisfy their needs and wants. A village, a city, India, or the whole world — each is an economy. Economics is the study of how a society uses its limited resources to meet its unlimited wants. That tension — limited resources, unlimited wants — is called scarcity, and it is the root of all economics.

Analogy

Think of your monthly pocket money. It is limited, but the things you want to buy are many. So you must choose — and every choice means giving up something else. That "next-best thing you gave up" is called opportunity cost. A whole country faces exactly this problem, just on a giant scale: should it spend more on roads or on schools? Economics is the science of making these choices well.

Two zoom levels: micro vs macro

Microeconomics = the close-up view. It studies individual units — a single household, one firm, one market, how a price is set. ("Why did onion prices rise?")
Macroeconomics = the big-picture view. It studies the whole economy together — total output (GDP), inflation, unemployment, government budgets. ("Is India's economy growing?")

UPSC's economy syllabus is mostly macroeconomics, plus how the government manages the economy.

The basic questions every economy must answer

No matter the country, an economy must decide three things: (1) What to produce? (food, phones, weapons…), (2) How to produce it? (by hand or by machine), and (3) For whom to produce? (who gets the goods — everyone, or only those who can pay). How a country answers these decides what "type" of economy it is (see 1.3).

1.2 — Factors of production: what you need to make anything

The four ingredients

To produce any good or service, you need four basic resources, called the factors of production:

Factor	What it means	Its reward/income
Land	All natural resources — soil, water, minerals, forests	Rent
Labour	Human physical & mental effort — workers	Wages
Capital	Man-made tools used to produce — machines, factories, tools (not money itself)	Interest
Entrepreneurship	The person who organises the other three, takes the risk & innovates	Profit

Common beginner confusion

In economics, "capital" does not mean money. It means the physical tools of production — a sewing machine, a tractor, a factory building. Money used to buy these is called financial capital, which is different. Keep this distinction clear; UPSC tests it.

1.3 — Types of economies: who is in charge?

Three models

Market (capitalist) economy — private individuals & firms own resources; decisions are driven by profit and the price mechanism ("the invisible hand"). Example idea: USA. Strength: efficiency & innovation. Weakness: inequality, ignores the poor.
Command (socialist) economy — the government owns and decides almost everything. Example idea: former USSR. Strength: equality & basic needs. Weakness: inefficiency, no incentive to innovate.
Mixed economy — a blend: private sector + government working together. India is a mixed economy. The market drives most activity, but the State steps in for public goods, the poor, and strategic sectors.

Analogy

Imagine a cricket match. A pure market economy is like letting players make all the rules themselves (fast but chaotic, the strong dominate). A command economy is the umpire controlling every ball (orderly but slow, no spontaneity). A mixed economy is a normal match: players play freely, but an umpire sets fair rules and protects the weaker side. India chose the umpire-plus-players model.

1.4 — Demand, supply & how prices are set

The most famous idea in economics

Demand = how much of a good buyers want to buy at a given price. Usually, price up → demand down (law of demand). Supply = how much sellers are willing to sell at a given price. Usually, price up → supply up (law of supply). The price settles where demand meets supply — called the equilibrium price. This is the "market mechanism" or "invisible hand".

Diagram — demand & supply

Where the red (demand) and green (supply) lines cross, the market "agrees" on a price. If demand rises, the red line shifts right and price goes up — that, in essence, is how shortages cause price rise.

1.5 — Goods, utility & the science of choice

Positive vs normative economics

Two ways economists talk: positive economics deals with facts — what is ("India's inflation was 5% last year"). Normative economics deals with opinions/values — what ought to be ("the government should spend more on the poor"). UPSC answers usually need positive facts first, then a balanced normative judgement.

Types of goods (know these labels)

Private goods — you must pay, and one person's use stops another's (a burger).
Public goods — non-excludable (can't stop anyone using) & non-rival (one's use doesn't reduce another's): street lighting, national defence. Markets under-supply these, so the government provides them.
Merit goods — good for society, so the State encourages them (education, vaccines). Demerit goods — harmful, so the State discourages/taxes them (tobacco, alcohol).
Normal vs inferior goods — as income rises you buy more of a normal good (cars) but less of an inferior good (cheap grain).
Substitutes vs complements — substitutes replace each other (tea/coffee); complements are used together (car/petrol).

Utility & why we stop buying

Utility = the satisfaction you get from a good. The Law of Diminishing Marginal Utility says each extra unit gives less added satisfaction than the one before. The first glass of water on a hot day is bliss; the fourth is "meh". This simple law explains the downward-sloping demand curve — we pay less for more.

Elasticity — how sensitive is demand to price?

Price elasticity of demand measures how much quantity demanded changes when price changes. Elastic goods (luxuries, e.g. cinema tickets) — demand drops sharply when price rises. Inelastic goods (necessities, e.g. salt, medicines) — demand barely changes. This is why governments can tax necessities (people keep buying) and why farm incomes can fall in a bumper-harvest year (food is inelastic).

Diagram — Production Possibility Frontier (opportunity cost)

The curve shows the maximum a country can produce of two things (say "guns vs butter") with limited resources. To get more butter you must give up some guns — that trade-off is opportunity cost. Inside the curve = wasted resources; outside = not yet possible.

Section 1 in one glance

Economy = producing & using goods · Economics = scarce resources vs unlimited wants · opportunity cost = next-best thing given up (PPF curve) · micro vs macro · 4 factors → rent/wages/interest/profit · market/command/mixed (India=mixed) · price = demand meets supply · positive (facts) vs normative (values) · goods: private/public/merit/demerit/normal/inferior · diminishing marginal utility · elastic (luxury) vs inelastic (necessity) demand.

Section 2

Measuring an economy — how big is it?

2.1 — The three sectors of an economy

Where output comes from

Every economy's production is grouped into three sectors:

Primary sector — using nature directly: agriculture, fishing, mining, forestry.
Secondary sector — turning raw materials into goods: manufacturing, industry, construction.
Tertiary sector — services (not physical goods): banking, IT, transport, education, healthcare.

As countries develop, workers usually move from primary → secondary → tertiary. In India, services (tertiary) produce the most output (~55%), but agriculture (primary) still employs the most people (~45%) — a key fact you will meet again in the advanced notes.

Diagram — three sectors

Some books add a Quaternary sector (knowledge: R&D, IT) and Quinary sector (top decision-makers). For UPSC basics, the three above are essential.

2.2 — GDP and its family (the size of the economy)

The headline number: GDP

Gross Domestic Product (GDP) is the total money value of all final goods and services produced inside a country in one year. It is the single most-used measure of an economy's size. If GDP goes up year on year, the economy is growing.

Analogy

GDP is like adding up the bills of everything everyone sold in the country in a year — every loaf of bread, haircut, car and software contract. "Final" means we count the finished bread, not the flour that went into it (to avoid double-counting).

A few cousins of GDP (don't panic — just the idea)

GVA (Gross Value Added) — output measured at the producer's end, sector by sector. GDP and GVA differ only by taxes/subsidies. Used to see which sector grew.
GNP (Gross National Product) — GDP + income Indians earn abroad − income foreigners earn here. ("National" = by Indians anywhere; "Domestic" = inside India by anyone.)
Per capita income — National income ÷ population. Tells us the average person's income, a better welfare measure than total GDP.
Nominal vs Real GDP — "Nominal" is at today's prices; "Real" removes the effect of inflation so we see true growth. Always compare real GDP across years.

Beginner traps

(1) GDP measures production inside the country, regardless of who owns it. (2) A high total GDP doesn't mean people are rich — divide by population (per capita) to judge living standards. (3) "Growth" should always mean real (inflation-adjusted) growth.

3 ways to measure the same GDP

Because every rupee spent is also a rupee earned and a rupee of output, GDP can be calculated three ways that should all match:

Production (value-added) method — add up the value added at each stage of production (avoids double-counting).
Income method — add up all incomes earned: wages + rent + interest + profit.
Expenditure method — add up all spending: C + I + G + (X − M) = Consumption + Investment + Government spending + (Exports − Imports). This formula is worth remembering.

Market price vs factor cost (one key adjustment)

The same output can be valued two ways. At market price = the price you actually pay (includes indirect taxes, minus subsidies). At factor cost (now called "basic price") = what producers actually receive (taxes removed, subsidies added back). The bridge: Market Price = Factor Cost + Net Indirect Taxes (indirect taxes − subsidies).

2.3 — The national-income family (GDP's relatives)

A simple ladder of terms

Starting from GDP, four small adjustments give the other aggregates. Don't memorise — just see the logic:

Term	How to get it	Plain meaning
GDP	Output made inside India	The starting point
GNP	GDP + net income from abroad	Output by Indians anywhere
NNP	GNP − depreciation	"Net" — after machines wear out
National Income (NNP at factor cost)	NNP − net indirect taxes	Income actually earned by people
Personal Income	NI − retained profits, + transfers	Income households receive
Disposable Income	Personal income − direct taxes	What you can actually spend/save

Depreciation = the wear-and-tear/value lost by machines & buildings over time. "Gross" includes it; "Net" removes it. Base year = a reference year (currently 2011-12 in India) used to compare real values across years and strip out inflation.

2.4 — The circular flow of income (how money goes round)

The big picture of an economy

An economy is a loop. Households own the factors (land, labour, capital) and sell them to firms, earning income (wages, rent, etc.). They then spend that income buying the goods & services firms produce. So money flows firms → households (as income) and households → firms (as spending), round and round. This is the circular flow of income.

Diagram — circular flow of income

The two arrows show money circulating endlessly between households and firms. Real economies also have "leakages" (savings, taxes, imports) and "injections" (investment, government spending, exports) — when injections > leakages the economy grows.

Section 2 in one glance

3 sectors (primary/secondary/tertiary); India = services biggest output, agriculture biggest employer · GDP = final goods/services made inside India in a year · 3 methods: production / income / expenditure (C+I+G+(X−M)) · market price = factor cost + net indirect taxes · ladder: GDP→GNP→NNP→National Income→Personal→Disposable · gross vs net = before/after depreciation · base year 2011-12 · circular flow = money loops between households & firms; injections vs leakages.

Section 3

Money, banks & prices

3.1 — What is money, really?

More than just notes & coins

Money is anything widely accepted in exchange for goods and services. Before money, people used barter (swapping goods directly — "I'll give you rice for your cloth"), which was clumsy. Money solves that. It has four functions: a medium of exchange (you can buy anything with it), a measure of value (prices are set in it), a store of value (you can save it), and a standard for deferred payment (you can borrow/lend in it).

3.2 — Money supply: how much money is in the economy (M0–M4)

Why "money" is measured in layers

"How much money exists in India?" has no single answer, because money comes in degrees of liquidity (how easily it can be spent right now). Cash in your hand is instantly spendable; a 5-year fixed deposit is not. So the RBI measures money supply in widening circles, labelled M0, M1, M2, M3, M4 — each adds a less-liquid layer to the one before.

The five measures — from narrowest to broadest

M0 (Reserve Money / "high-powered money") = currency in circulation + bankers' deposits with RBI + other deposits with RBI. This is the money the RBI itself creates — the base of everything.
M1 (Narrow Money) = currency with the public + demand deposits (your current/savings account money you can withdraw anytime) + other deposits with RBI. Most liquid spendable money.
M2 = M1 + savings deposits with post-office savings banks. (A slightly wider circle.)
M3 (Broad Money) = M1 + time deposits with banks (fixed deposits). This is the most important and most-watched measure — when economists say "money supply", they usually mean M3.
M4 = M3 + all post-office deposits (except National Savings Certificates). The broadest, least liquid measure.

Memory aid: liquidity falls as you go M1 → M4 (M1 is the most "spendable", M4 the least). M0 is a different idea — the RBI's base money, not a liquidity ranking.

Analogy

Think of money as water in different containers. M1 is water in an open glass — drink it instantly. M3 adds water in a sealed bottle (a fixed deposit) — drinkable, but you must open it first. M0 is the tap itself — the RBI controls the tap, and from that base water, banks fill many glasses through lending.

How banks "create" money — the money multiplier

Here's the surprising part: banks create money. When you deposit ₹100, the bank keeps a small reserve (say ₹10) and lends out ₹90. That ₹90 gets deposited elsewhere, and ₹81 is lent again, and so on. So one ₹100 of base money becomes many times more in total deposits. This multiplication is the money multiplier, and it is exactly why the RBI controls the base (M0) and reserve ratios (CRR/SLR) to manage how much total money (M3) the banking system can create.

3.3 — Banks and the RBI

What banks do

A bank takes deposits from people who have spare money and gives loans to people who need money, charging more interest on loans than it pays on deposits — that gap is its profit. By doing this, banks move idle savings into productive use (a factory loan, a home loan). This is called financial intermediation.

The boss of all banks: the RBI

The Reserve Bank of India (RBI) is India's central bank — the "bank of banks" and the authority that manages money. Its main jobs: issue currency, control inflation, regulate & supervise banks, and manage the country's foreign-exchange reserves. The RBI's most famous tool is the repo rate — the interest rate at which it lends to banks. If the RBI raises the repo rate, loans become costlier, people borrow & spend less, and prices cool down. If it cuts the rate, borrowing is cheaper and the economy speeds up. This whole activity is called monetary policy.

Analogy

Think of the economy as a car and the repo rate as the accelerator/brake. When the economy "overheats" (prices rising too fast), the RBI presses the brake (raises rates). When the economy is sluggish, it presses the accelerator (cuts rates). The RBI's goal is a smooth, steady ride — not too fast, not too slow.

3.4 — The RBI's toolkit & the types of banks

The RBI's main levers (you'll meet these everywhere)

The RBI controls money and credit using two kinds of tools.

Quantitative tools (affect the amount of money):

Repo rate — rate at which RBI lends to banks (the main signal). Reverse repo / SDF — rate at which RBI borrows from / absorbs money from banks.
CRR (Cash Reserve Ratio) — % of deposits banks must keep as cash with the RBI (earns no interest).
SLR (Statutory Liquidity Ratio) — % of deposits banks must keep in safe liquid assets (government bonds, gold) with themselves.
MSF — emergency rate, the ceiling; Bank Rate — long-term version of repo.
OMO (Open Market Operations) — RBI buys/sells government bonds to add or remove money from the system.

Qualitative tools (affect where credit goes): margin requirements, moral suasion (persuasion), and selective credit controls.

Simple rule: raise CRR/SLR/repo → less money, cools inflation; lower them → more money, boosts growth.

The types of banks in India

Commercial banks — the everyday banks: Public-sector (govt-owned, e.g. SBI), private, foreign, and Regional Rural Banks (RRBs).
Cooperative banks — member-owned, serve local/rural communities.
Small Finance Banks & Payments Banks — newer "differentiated" banks. Payments banks can take small deposits & offer payments but cannot give loans.
NBFCs (Non-Banking Financial Companies) — lend money but are not banks: they cannot accept demand deposits or issue cheques.
NPA (Non-Performing Asset) — a "bad loan" the borrower has stopped repaying (90+ days). Large NPAs weaken banks — a recurring policy problem.

3.5 — Inflation: when money buys less

The idea

Inflation is a sustained rise in the general level of prices. When inflation is high, each rupee buys less than before — your money loses value. A little inflation (say 4%) is normal and even healthy; very high inflation hurts the poor most.

Two main causes

Demand-pull inflation — too much money chasing too few goods. Demand outruns supply, so prices rise. (Everyone wants to buy, shops run short.)
Cost-push inflation — the cost of making things rises (fuel, wages), so sellers raise prices. (Petrol up → transport up → vegetables up.)

A vocabulary of price changes (recognise these)

By speed: creeping (slow, mild) → galloping (fast, double-digit) → hyperinflation (out of control, money becomes worthless).
Deflation — prices falling (dangerous: people delay buying, economy slows). Disinflation — inflation still positive but slowing down. Stagflation — the bad combo of high inflation + stagnant growth + unemployment.
Core inflation — inflation excluding volatile food & fuel, to see the underlying trend.

How inflation is measured

CPI (Consumer Price Index) — retail prices of a typical household shopping basket. This is the RBI's target index; the target is 4% (within a 2–6% band).
WPI (Wholesale Price Index) — wholesale/bulk prices between businesses (no services).
GDP deflator — the broadest price measure, covering everything in GDP.

Who inflation hurts: savers & fixed-income earners (money loses value) and the poor (food costs more); it can help borrowers (they repay in cheaper rupees).

Section 4

Government & the economy

4.1 — The Budget: the government's yearly money plan

What a budget is

The Union Budget is the government's annual statement of how much money it expects to earn (receipts) and how much it plans to spend (expenditure) in a financial year (1 April–31 March). Just like a household plans its income and expenses, the government plans for the whole country. The action of using spending and taxes to steer the economy is called fiscal policy.

Diagram — a budget in one picture

A budget has two sides: what comes in, and what goes out. When spending is more than income, the shortfall is covered by borrowing — that shortfall is the deficit (4.3).

The budget has two halves (revenue & capital)

Both the "money in" and "money out" sides are split into two accounts:

Revenue account — the day-to-day stuff. Revenue receipts (taxes, fees — money that doesn't have to be repaid) and revenue expenditure (salaries, interest, subsidies — spending that creates no asset).
Capital account — the long-term stuff. Capital receipts (borrowings, disinvestment — create a liability or reduce assets) and capital expenditure (roads, schools, machinery — spending that creates an asset).

Why it matters: capital expenditure builds the future (good borrowing), while too much revenue expenditure funded by borrowing is risky.

Where the money sits: the three government funds

Consolidated Fund of India — the main account; all government income goes here, and withdrawals need Parliament's approval.
Contingency Fund — an emergency reserve at the President's disposal for urgent unforeseen spending.
Public Account — money the government merely holds for others (provident funds, small savings); no Parliament vote needed to pay it back.

4.2 — Taxes: where the government's money comes from

Two big families of tax

Direct tax — paid directly by the person/company on whom it is levied; cannot be passed on. Examples: Income Tax, Corporate Tax. Generally "progressive" (the rich pay a higher rate).
Indirect tax — levied on goods/services and passed on to the final buyer in the price. Main example: GST (Goods & Services Tax). Generally "regressive" (rich and poor pay the same rate on a product).

GST (since 2017) merged many older indirect taxes into "One Nation, One Tax" to create a single national market.

How tax rates can be designed

Progressive tax — the rich pay a higher rate (income tax). Reduces inequality.
Regressive tax — takes a bigger share from the poor (most indirect taxes — a ₹2 tax on salt hits a poor buyer harder).
Proportional tax — everyone pays the same flat rate.

Cess = a tax levied for a specific purpose (e.g. health & education cess) — not shared with states. Surcharge = a "tax on a tax" on high incomes. Both go to the Centre, which is why states dislike them.

4.3 — Deficits and subsidies

When spending exceeds income

If the government spends more than it earns, the gap is a deficit, which it fills by borrowing. The most important one is the fiscal deficit = total spending − total income (excluding borrowing). A fiscal deficit is not automatically bad: borrowing to build roads and schools (assets that boost future growth) is healthy; borrowing just to pay salaries and subsidies is risky if it grows too large.

Subsidies

A subsidy is financial help the government gives to make something cheaper for citizens — e.g. cheaper food, fuel, or fertiliser. Subsidies help the poor and ensure essentials, but if poorly targeted they strain the budget. Modern reform uses Direct Benefit Transfer (DBT) — sending money straight to a citizen's bank account — to cut leakages.

The three deficits you should know

Revenue deficit = revenue expenditure − revenue receipts. Means the government is borrowing even for its day-to-day running (a warning sign).
Fiscal deficit = total expenditure − total receipts (excluding borrowing). The headline number; it equals how much the government must borrow in the year.
Primary deficit = fiscal deficit − interest payments. Strips out the cost of past debt to show the current year's fresh borrowing.

To keep deficits in check, India has a law — the FRBM Act, 2003 (Fiscal Responsibility & Budget Management) — that sets discipline targets for government borrowing.

Section 4 in one glance

Budget = govt's yearly income & spending plan · fiscal policy = taxes/spending to steer economy · two accounts: revenue (day-to-day) vs capital (asset-building) · 3 funds: Consolidated / Contingency / Public Account · taxes: direct (income/corporate) vs indirect (GST); progressive vs regressive; cess & surcharge · 3 deficits: revenue / fiscal (key = borrowing) / primary (minus interest) · FRBM Act 2003 = borrowing discipline · subsidy + DBT cuts leakages.

Section 5

Growth, development & people

5.1 — Growth vs development: not the same thing

The crucial difference

Economic growth = the economy producing more (a rise in GDP). It is purely about quantity. Economic development is wider: growth plus better lives — health, education, equality, a clean environment, dignity. An economy can grow while many people stay poor; growth is necessary but not enough for development.

Analogy

Growth is like a person gaining weight; development is like a person becoming genuinely healthier and stronger. More mass (GDP) is not the same as good health (development). UPSC loves answers that show you understand this difference.

Measuring development: HDI

Since GDP ignores quality of life, the UN created the Human Development Index (HDI). It combines three things: health (life expectancy), education (years of schooling), and income (per-capita income). A score from 0 to 1 — higher is better. It shifts the focus from "how much money?" to "how good are people's lives?"

5.2 — Poverty, unemployment & inclusive growth

Key people-centred terms

Poverty — lacking the income/resources for a minimum standard of living. Measured against a poverty line. "Multidimensional" poverty also counts health, education & living conditions, not just income.
Unemployment — people willing and able to work but unable to find a job. Special Indian types: disguised (more people working on a farm than needed) and seasonal (work only part of the year).
Inclusive growth — growth whose benefits reach everyone, especially the poor, women and backward regions — through jobs, education, health and financial access. It is one of UPSC's favourite themes.
Demographic dividend — the economic boost a country can get when it has a large young working-age population (India's situation now) — if it creates enough jobs and skills.

How poverty is measured

A poverty line is the minimum income/consumption needed for basic living; people below it are "poor". India's lines were defined by expert committees — the Tendulkar Committee and later the Rangarajan Committee. A modern, richer measure is the Multidimensional Poverty Index (MPI), which counts not just income but also health, education and living standards (cooking fuel, sanitation, electricity) — so a family can be "poor" in several ways at once. NITI Aayog publishes India's National MPI.

Unemployment — the types & the measuring terms

Types:

Disguised — more people on a job than needed (4 farmers doing 2 farmers' work); removing some changes nothing.
Seasonal — work only in certain seasons (farm labour, tourism).
Structural — skills don't match available jobs; long-term.
Frictional — short gap while changing jobs.
Cyclical — caused by an economic slowdown.

The three measuring terms (from the official PLFS survey): LFPR (Labour Force Participation Rate) = share of people working or looking for work; WPR (Worker Population Ratio) = share actually employed; Unemployment Rate = share of the labour force that is jobless. The data source is the Periodic Labour Force Survey (PLFS).

5.3 — Inequality & how we measure it

Measuring the gap between rich and poor

Inequality is the uneven distribution of income or wealth. The main tools:

Gini coefficient — a single number from 0 (perfect equality — everyone has the same) to 1 (perfect inequality — one person has everything). Higher = more unequal.
Lorenz curve — a graph showing how far actual income distribution bends away from a perfectly equal line; the Gini is calculated from it.

Growth can raise average incomes while inequality widens — which is exactly why "inclusive growth" matters.

Beyond HDI: the development indices family

HDI — health + education + income (the headline development measure).
IHDI — HDI adjusted for inequality (a fairer picture).
GII (Gender Inequality Index) — gaps between men and women.
SDGs (Sustainable Development Goals) — 17 global goals for 2030 (no poverty, zero hunger, quality education, climate action…), agreed at the UN; India tracks progress via NITI Aayog's SDG India Index.

Section 5 in one glance

Growth (quantity) ≠ development (quality + equity) · HDI = health+education+income; variants IHDI, GII · poverty line (Tendulkar, Rangarajan) & MPI (multidimensional) · unemployment: disguised/seasonal/structural/frictional/cyclical; LFPR/WPR/UR from PLFS · inequality: Gini (0–1) & Lorenz curve · inclusive growth = benefits reach all · demographic dividend = young population (if jobs created) · SDGs = 17 goals for 2030.

Section 6

India's economy story — a 3-minute timeline

From 1947 to today, simply

1947–1991 — The planned era. After independence, India was poor and chose economic planning: the government led the economy through Five-Year Plans and a Planning Commission (1950), built public-sector factories, and tightly controlled private business (the "licence raj" — you needed a government permit for almost everything). Growth was slow (the so-called "Hindu rate of growth" of ~3.5%).
1991 — The big turn (LPG reforms). A severe crisis (India nearly ran out of foreign currency) forced bold reforms under PM Narasimha Rao & FM Manmohan Singh: Liberalisation (remove controls), Privatisation, Globalisation (open to the world). The economy was unleashed and growth accelerated.
1991–today — The fast-growth era. India became one of the world's fastest-growing major economies, a global services & IT hub, and (by total size) among the largest economies. In 2015 the NITI Aayog replaced the Planning Commission. Challenges remain: enough good jobs, stronger manufacturing, and making growth inclusive.

Names & terms you'll now recognise

Planning Commission · NITI Aayog · Five-Year Plans · licence raj · 1991 LPG reforms · Manmohan Singh · mixed economy · services-led growth · jobless growth · inclusive growth · demographic dividend. You don't need detail yet — just recognise them. The advanced files explain each fully.

Money, banking & prices

RBI: Reserve Bank of India — the central bank; issues currency, controls inflation, regulates banks.
Repo rate: Rate at which RBI lends to banks; up = costlier loans (cools economy), down = cheaper loans (boosts economy).
Inflation: Sustained rise in prices; money buys less. Demand-pull (excess demand) or cost-push (rising costs).
CPI / WPI: Consumer Price Index (retail prices, RBI's target) & Wholesale Price Index (bulk prices).

Financial inclusion: Giving everyone access to banking, credit, insurance & pensions (e.g. Jan Dhan accounts).

Government, budget & tax

Union Budget: Government's yearly plan of income (receipts) and spending (expenditure).
Fiscal deficit: The gap when government spends more than it earns; filled by borrowing.
Revenue vs Capital expenditure: Revenue = day-to-day spending (salaries, interest); Capital = asset-building (roads, schools).

What to read next

Your study path from here

Now that the foundations are clear, move to the three Mains-level GS3 economy notes in order:

Economy, Planning, Growth, Inclusive Growth & Budgeting (plus Monetary Policy, Banking & External Sector). This deepens everything in Sections 2–5 here.
Land Reforms, Liberalization & Industrial Policy. This expands Section 6's story.
Infrastructure & Investment Models.

Read a topic here first to understand it, then read the matching advanced section for exam depth, data, diagrams and previous-year questions. Re-visit this glossary whenever a word trips you up.

A beginner's 6-step revision habit

Read a concept here until you can explain it to a friend in one line.
Note the key term (blue word) in your own notebook with a one-line meaning.
Then open the matching advanced section.
Watch one explainer video if a topic still feels abstract.
Follow simple budget/RBI news to see concepts in action.
Revise this glossary weekly — it builds vocabulary fast.

Remember

Economics is just organised common sense about choices. You already make economic decisions every day. UPSC only asks you to apply that thinking to the whole country. Start here, go slow, and the advanced notes will fall into place.
