1 Choices and Limited Resources
Should you spend your pocket money on snacks, or save it for shoes? Should a farmer grow wheat or barley? Should a government build more highways, or more hospitals? These are all examples of economic choices, decisions that individuals, enterprises and governments must make every day because resources are limited.
1.1 Needs vs wants
Needs
- Essentials for survival
- Food, water, shelter
- Do not change much over time
Wants
- Things we desire but can live without
- Gadgets, vacations, luxury items
- Unlimited, and keep changing
Bicycle → motorbike → car: a want becomes a habit, then a bigger want appears. That is what “wants are unlimited and keep changing” means.
1.2 Resources are scarce
Resources are the factors used for the production of goods and services. They can be natural, like water and coal, or human-made, like capital and technology. In Class 8 you learnt these are the four factors of production: land, labour, capital and technology.
Every resource is limited, and one resource often has more than one use. Steel, for example, can become any one of these, but not all of them from the same batch:
Medical equipment
Hospital instruments and machines
Aircraft manufacturing
Aeroplane parts and frames
Refrigerator manufacturing
Home appliances
Choosing one use means giving up the others, this is the idea behind opportunity cost.
Opportunity cost is the value of the next-best alternative that is given up when one option is chosen instead.
Situation. One piece of land can grow either barley or wheat, not unlimited amounts of both.
Answer. Growing more barley means giving up some wheat, the opportunity cost of the extra barley.
1.3 The Production Possibility Curve (PPC)
The farmer’s possible combinations of barley and wheat can be written as a table:
| Combination | Barley (in kg) | Wheat (in kg) |
|---|---|---|
| A | 0 | 100 |
| B | 25 | 90 |
| C | 50 | 70 |
| D | 75 | 40 |
| E | 100 | 0 |
The Production Possibility Curve (PPC) is the curve showing the different combinations of two goods that can be produced using all the available resources efficiently.
Plotted with barley on the x-axis and wheat on the y-axis, this forms a downward-sloping curve. From A to E, barley rises and wheat falls, the lost wheat being its opportunity cost.
The PPC shows the maximum output possible using resources efficiently, without wastage. A point inside the curve wastes resources; a point outside it is not possible with the resources currently available.
2 What Does Economics Deal With?
“Economics” comes from the Greek oikonomia: oikos (household) + nemein (management), so it first meant “household management”. Nations, not just households, must plan their limited resources too. The word economy itself has two related senses: a country’s overall production, consumption and flow of money, or the whole system of production, distribution and trade within a country.
Economics is the discipline that deals with how choices are made by optimising the use of limited resources to satisfy needs and wants.
Economics explains how economic entities (consumers, producers, governments, financial institutions) interact: how wages are earned, how prices are set in the market (any place, physical or virtual, where buying and selling happens), and how government policy (a course of action adopted by governments or organisations) affects prices and jobs.
2.1 Good decisions need data, not guesswork
This planning uses data (facts and statistics collected for reference or analysis), gathered through surveys (systematic data collection on economic conditions), such as government surveys and company financial statements.
2.2 What economists actually do
Policy-making
Guiding governments on taxation or welfare spending
Business consulting
Helping firms plan growth or improve efficiency
Research and education
Studying economic trends and teaching others
Finance
Advising investors on where to invest
The Economic Survey of India, by the Ministry of Finance, is presented in Parliament just before the Union Budget. It reviews the past year’s economy and helps shape the coming Budget.
3 Key Questions in Economics
Unlimited wants meeting limited resources creates scarcity, and scarcity forces every economy to answer three key questions.
What to produce
Which goods, and how much of each?
How to produce
Which resources and methods to use?
For whom to produce
Who gets to use and benefit from it?
3.1 What to produce, and for whom?
Situation. Should farmers grow sugarcane and paddy (water-intensive, high profit), or millets and pulses (drought-resistant, save water and soil)?
Answer. The opportunity cost of sugarcane is the saved water and healthier soil given up, trading short-term profit for long-term sustainability.
“For whom to produce” depends on people’s income, tastes and lifestyle, as this table of shoes shows:
| Type of shoe | Made for | Key features |
|---|---|---|
| School shoes | Students | Simple design, durable, affordable |
| Office-wear shoes | Working professionals | Comfort, formal look, leather or polished material |
| Sports shoes | Athletes and fitness enthusiasts | Rubber soles, lightweight, grip and flexibility |
| Casual shoes/slippers | Daily use, general public | Comfortable and affordable |
Producers weigh buyer preference, spending power and demand before deciding what to make, so resources are not wasted on things nobody wants.
Healthcare and education, or defence and space exploration? Governments face this “what to produce” trade-off too.
3.2 How to produce?
Land
Natural resource used in production
Labour
Human effort put into production
Capital
Machines, tools and money invested
Technology
Methods and know-how used to produce
Labour-intensive
- More workers, less machinery
- Common in agriculture, handicrafts
- Preferred when labour is cheap
Capital-intensive
- More machines, fewer workers
- Common in steel, automobiles
- Preferred when machines are affordable
Situation. A garment manufacturer must choose between labour-intensive and capital-intensive production.
Answer. Expensive machines favour labour; affordable machines favour automation. Customised clothes need skilled labour, mass-produced garments suit machines. The choice depends on capital cost, technology, product type, and government laws.
4 Economic Systems and How Choices Are Made
How resources are organised and who controls decisions differs by country; this mechanism is the economic system.
An economic system is the mechanism that defines how production, consumption, and distribution of goods, services, and resources are organised in a country.
There are three kinds of economic systems: planned, market, and mixed.
| Planned economy | Market economy | Mixed economy | |
|---|---|---|---|
| Who decides | A central government authority decides what, how, and for whom | Demand and supply decide, with little government intervention | Government and private sector both decide |
| Ownership | Government owns most resources: land, factories, banks, transport | Mostly private: individuals and companies own factories, shops, land | Mix of private ownership and public-sector companies |
| Government’s role | Controls production through strict permits and licences | Acts like a referee: ensures safety and law and order, does not fix prices | Regulates the private sector while allowing it to compete |
| Effect on competition | Restricts competition among private enterprises | Many producers compete, which improves quality and lowers prices | Fair competition rules alongside welfare programmes and public goods |
| Examples | Former Soviet Union, North Korea, Cuba | United States of America, Japan, Hong Kong | India (post-1991), China (post-1978), Germany, Sweden |
Even the USA and Singapore, market economies, have real government involvement. No economy is 100% planned or 100% market.
Public goods are goods and services available to all individuals without anyone being excluded. One person using them does not stop others from using them too, for example parks, roads, police services, street lights, and basic education.
4.1 India’s economic journey
- Wants are unlimited and keep changing, but resources are always limited (scarce)
- Every choice has an opportunity cost: the value of the next-best option given up
- The PPC table/curve shows the maximum combinations of two goods producible with the resources available
- Economics literally means “household management” (oikonomia), but applies to nations too
- Good economic decisions rely on real data and surveys, not guesswork
- Every economy must answer three questions: what to produce, how to produce, for whom to produce
- Planned economies: government decides everything. Market economies: demand and supply decide. Mixed economies: both play a role
- Almost every real economy, including India’s, is mixed; India moved from a planned approach before 1991 to today’s more market-oriented mixed economy
