The Nature of the Economic Problem

Scarcity is a situation where there are not enough resources to satisfy everybody’s wants. It is when unlimited wants exceed limited resources.
Examples of scarcity faced by the four economic decision-makers:
- Consumers: A student on a fixed monthly allowance cannot afford both a new phone and a Jio data top-up, so must choose between them.
- Workers: A software engineer in Bengaluru has only 24 hours in a day. Working overtime means giving up leisure or family time.
- Producers: A Punjab farmer has limited land and water, so must choose between growing wheat or rice.
- Governments: The Union Budget has limited tax revenue, so the government must choose between spending on defence, education or roads. More spent on one means less available for the others.
This gives rise to a choice. The economy has to answer the following basic economic questions:
- What to produce? Which goods and services to make, and how much of each (for example, more food crops or more vaccines).
- How to produce? Which methods and resources to use, such as labour-intensive or capital-intensive production.
- For whom to produce? Who receives the output, decided by income and willingness to pay, or by government allocation.
Needs: Needs are something which are required for the survival of the human being.
- Example: Food, clothing, shelter
Wants: Wants are something which are not required for the survival but they add comfort to ones life.
- Example: Luxury car, branded T shirt

Types of Goods

Economic Goods: A product which requires resources to produce it and therefore has an opportunity cost.
- Example: Education, Bottled Water
Free Goods: A product which does not require any resources to make it and so does not have an opportunity cost.
- Example: Air, Wind
Capital Goods: Capital goods are those goods which are required to produce other goods.
- Used by: Producers
- Purpose: Business
- Example: Pizza Ingredients, Taxi
Consumer Goods: Consumer goods are those goods which are directly used for final consumption.
- Used by: Consumers
- Purpose: Consumption
- Example: Pizza, Car
Durable Goods: Durable goods are the goods which last for a longer period of time. It can be used many times.

Example: Refrigerator, Washing Machine, Machinery

Perishable Goods: It cannot be stored and preserved for a longer period of time. It can be used only once.
- Example: Fruits, Vegetables, Bread
Merit Goods: People underestimate the benefits of these goods. Merit goods have positive externalities.
- Example: Education, Vaccination, Healthcare
Demerit Goods: People underestimate the costs of these goods. Demerit goods have negative externalities.
- Example: Tobacco Products, Alcohol, Violent Games and Movies

Common Mistakes That Lose Marks

The trap is in bold. Read the fix after it.

“Scarcity means a shortage.” Wrong. Scarcity is permanent and exists in every economy, even rich ones: resources are limited but wants are unlimited. A shortage is temporary: demand is greater than supply at the current price, like onions after a poor monsoon.
“Wants are limited.” Wrong. Needs (food, water, shelter) are what we must have to survive. Wants are everything we would like to have, and they never run out: once you own a phone, you want a better one.
Stopping at “resources are scarce”. Complete the chain: scarcity, so people must choose, so every choice has an opportunity cost. An “explain” question needs the links, not just the word.
“A free good is anything you don’t pay for.” Wrong. A free good is not scarce and has no opportunity cost (air, sunlight, sea water). A free government school or a free vaccine is an economic good: it uses scarce teachers, buildings and medicine, paid for by taxpayers.
Ignoring whose problem it is. The economic problem affects every economic agent: consumers (limited income), workers (limited time), producers (limited resources) and governments (limited tax revenue). Use the agent named in the question.
Goods vs services. Goods are tangible (a cricket bat). Services are intangible (a haircut, a bank account, a Zomato delivery). The food is a good; the delivery is a service.

Exemplar Questions

Define finite resource. (2 marks)
- A resource is an aid to production (1) which is limited in supply (1) it cannot be replaced over time / fast enough / will run out (1) to keep pace with consumption (1).
Explain what is meant by the ‘economic problem’. (2 marks)
- There are finite/limited/scarce resources (1) but unlimited/infinite wants (1) and so it is necessary for a choice to be made (1).
Explain why the economic problem can never be solved. (4 marks)
- the economic problem is scarcity (1).
- infinite wants (1) finite resources (1).
- wants exceed resources (1) as wants grow faster than resources/growth of resources will not exceed growth of wants (1).
Explain why scarcity forces households to make choices. (4 marks)
- The economic problem is that resources are limited while wants are unlimited, so not every want can be satisfied. For households, this means limited income cannot buy everything they want, forcing them to choose which goods and services to buy and which to give up — the goods not bought represent the opportunity cost of the goods chosen.
Explain two examples of the basic economic problem facing a government. (4 marks)
- Example 1: A limited tax revenue/budget means the government must choose between, e.g., healthcare and education (1); spending more on one means less is available for the other, which is the opportunity cost (1). Example 2: Limited funds mean the government must choose between, e.g., fuel subsidies and building infrastructure (1); resources used on one cannot be used on the other (1).
Distinguish between an economic good and a free good. (4 marks)
- An economic good requires scarce resources to produce (1), so it has an opportunity cost (1), e.g. bottled water. A free good needs no resources to produce (1), so it has no opportunity cost (1), e.g. air.
Explain, using examples, the difference between a merit good and a public good. (4 marks)
- A merit good is one that is more beneficial to consumers than they realise, so it would be under-consumed if left entirely to the market, e.g. education, where people may undervalue its long-term benefits. A public good is one that is non-excludable and non-rival, so private firms have no incentive to supply it at all because of the free-rider problem, e.g. street lighting, which benefits everyone whether they pay for it or not. The key difference is that a merit good is under-provided by the market, while a public good would not be provided at all.
