Basic Economic Terms and the Four Entities of an Economy (ICSE Class 9)

Updated 18 October 2026 · Fact-checked

Economics uses precise terms: wants (desires backed by ability and willingness to pay), goods (tangible) and services (intangible), wealth (scarce, transferable goods with utility), utility (want-satisfying power), production, consumption, sustainable consumption, factors of production, market, price, value, income, saving, welfare and economy. An economy has four entities: households, firms, the government sector and the foreign sector.

Notice that households and firms exchange factors and goods, while the government and foreign sector link to both of them.

Understand Basic Economic Terms and the Four Entities of an Economy

Wants, goods and services. Wants are human desires backed by ability and willingness to pay; they are unlimited, recur and differ in urgency. Goods are tangible things that satisfy wants (rice, a shirt) and can be stored; services are intangible activities (teaching, banking, a haircut) produced and used at the same time. Free goods are plentiful gifts of nature with no price (air); economic goods are scarce and have a price.

Wealth and utility. Wealth means goods and assets that have utility, are scarce and can be transferred, so they have money value (a building, gold, shares). Air has utility but is not wealth because it is not scarce. Utility is the want-satisfying power of a good or service; it is not the same as usefulness and depends on person, place and time.

Production and consumption. Production is the creation of goods and services that have utility and exchange value. Consumption is the use of goods and services to satisfy wants directly. Sustainable consumption means meeting present needs while reducing waste and pollution so that resources remain for the future (a cloth bag, repairing instead of discarding, saving electricity).

Factors of production. Land (natural resources), labour (human effort), capital (man-made aids such as machines) and entrepreneur (organises the other three and bears the risk).

Market, price and value. A market is the arrangement through which buyers and sellers of a commodity come into contact, in person, by phone or online; it is not necessarily a place. Value is value-in-exchange, the quantity of other goods for which a good can be exchanged; value expressed in money is price.

Income, saving, welfare, economy. Income is the money earned over a period (wages, rent, interest, profit). Saving is the part of income not spent on consumption: Saving = Income - Consumption. Welfare is the well-being of people; economic welfare is the part measurable in money. An economy is the system in which people earn their living through production, consumption, exchange, saving and investment.

The four entities.

  • Households: individuals or families who own the factors of production, supply them to firms, earn incomes and consume.
  • Firms: producing units that hire factors from households and produce goods and services for sale.
  • Government sector: central, state and local governments that make laws, collect taxes and provide public goods and services (defence, roads, schools, hospitals).
  • Foreign sector: all economic dealings with other countries, such as exports, imports and flows of money and capital.

Households supply factors and receive income; firms sell goods to households, the government and foreigners; the government taxes and spends.

Basic Economic Terms and the Four Entities of an Economy in real life

The idea, met in an everyday situation. Answer the question in your own words, then compare with the model answer. The one-line hook is what to remember.

Saving in a household

Suppose a family earns Rs 40,000 in a month and spends Rs 31,000 on food, rent, fees and travel.

Find the saving and the percentage of income saved.

Try it first, then show the solutionSolution
  1. Saving = Income - Consumption = 40,000 - 31,000 = Rs 9,000.
  2. Percentage saved = 9,000 / 40,000 x 100 = 22.5 per cent.

Answer: Saving is Rs 9,000, which is 22.5 per cent of income.

Memory hook: Income minus spending is saving.

Basic Economic Terms and the Four Entities of an Economy: solved examples

Ordered from board level to HOTS. Try each one before you open the solution.

Example 1: Value in money · 1 mark · MCQBoard level

Value expressed in terms of money is called:
(a) wealth (b) utility (c) price (d) income

Try it first, then show the solutionSolution
  1. Price is value expressed in money.

Answer: (c) price

Example 2: Saving and consumption · 3 marks · Short answerHarder board level

A family's monthly income is Rs 40,000 and its consumption is Rs 31,000. Find its saving and the percentage of income saved.

Try it first, then show the solutionSolution
  1. Saving = Income - Consumption. (1 mark)
  2. Saving = 40,000 - 31,000 = Rs 9,000. (1 mark)
  3. Percentage saved = 9,000 / 40,000 x 100 = 22.5 per cent. (1 mark)

Answer: Rs 9,000 and 22.5 per cent

Example 3: Evaluate two statements · 3 marks · Short answerHarder board level

Evaluate: (a) "Utility and usefulness mean the same." (b) "Value and price mean the same."

Try it first, then show the solutionSolution
  1. (a) Wrong: utility is the want-satisfying power of a good and depends on person, place and time, whereas usefulness suggests benefit; for example, a woollen sweater has more utility in a cold hill town in December than in a hot coastal city. (1 mark)
  2. (b) Value is the quantity of other goods a good can be exchanged for. (1 mark)
  3. Price is value expressed in money, so every price is a value but value need not be expressed in money. (1 mark)

Answer: Neither statement is correct; utility depends on person, place and time, and price is only value in money.

Example 4: Case study: the four entities · 4 marks · Case-basedHOTS / competency

In an imaginary economy, households supplied labour to firms and earned wages of Rs 600 crore. They spent Rs 500 crore on goods from firms. Firms also sold goods worth Rs 30 crore to other countries and the government collected taxes of Rs 40 crore which it spent on schools.
(i) Name the entity that supplies labour and the entity that pays the wages. (1)
(ii) Find the saving of households, using Saving = Income - Consumption. (1)
(iii) Which entity buys the exports and which entity spends the taxes? (2)

Try it first, then show the solutionSolution
  1. (i) Households supply labour; firms pay the wages.
  2. (ii) Saving = 600 - 500 = Rs 100 crore.
  3. (iii) The foreign sector buys the exports; the government sector spends the taxes on schools.

Answer: (i) households and firms (ii) Rs 100 crore (iii) foreign sector, government sector

Example 5: Sustainable consumption · 3 marks · Short answerHarder board level

What is sustainable consumption? Give three examples from daily life and explain why it matters.

Where students lose marks in Basic Economic Terms and the Four Entities of an Economy

The slips examiners see most often, and what to write instead.

  • Mistake: Forgetting that saving is income minus consumption

    Saving is added to consumption by mistake.

    Wrong working

    Saving = Income + Consumption

    Right working

    Saving = Income - Consumption

    Do this: Write the formula first.

    Usually costs: 1 mark

  • Mistake: Calling every good wealth

    Scarcity is ignored.

    Wrong working

    Air is wealth

    Right working

    Air has utility but is not scarce, so it is not wealth

    Do this: Check scarcity and transferability.

    Usually costs: 1 mark

  • Mistake: Mixing value and price

    Both are connected.

    Wrong working

    Value is price

    Right working

    Value is exchange power; price is value in money

    Do this: Define each separately.

    Usually costs: 1 mark

Exam tips

  • Give a definition and an example for every term.
  • Write Saving = Income - Consumption before substituting numbers.
  • State the four entities in the order households, firms, government sector, foreign sector.
  • Mention that a market is an arrangement, not just a place.

  5. Q5 · 3 marks · Short answerHOTS / competency

    "A diamond ring is wealth but fresh air is not, though both have utility." Explain.

    Hint

    Which conditions must wealth meet?

    Answer

    Wealth must have utility, be scarce and be transferable with money value. A diamond ring meets all three. Fresh air has utility but is not scarce and cannot be transferred for a price, so it is not wealth.
