Key concepts

Resources and their types

Resources are anything that can be used to produce goods and services or to satisfy human wants.

Types:
1. Natural resources: gifts of nature: land, water, forests, minerals, sunlight, wind. They can be (a) renewable: replaced naturally over time, such as forests, water, solar energy; or (b) non-renewable: limited stock that cannot be replaced in human time, such as coal, petroleum, iron ore.
2. Human resources: people with their physical effort, skill, knowledge and health: farmers, engineers, teachers, doctors.
3. Capital (man-made) resources: things made by people to help further production: machines, tools, buildings, roads, dams, computers.

In production terms, these appear as land (natural), labour and entrepreneur (human) and capital (man-made).

Worked example

(2 marks) Classify as natural (renewable or non-renewable), human or capital resources: (a) a tractor; (b) coal; (c) a skilled mechanic; (d) a forest.

Try it first, then show the solutionSolution

1. (a) Tractor: capital (man-made) resource. (b) Coal: natural, non-renewable - 1 mark.
2. (c) Skilled mechanic: human resource. (d) Forest: natural, renewable - 1 mark.

Answer: (a) Capital resource; (b) natural, non-renewable; (c) human resource; (d) natural, renewable.

Limited resources (scarcity)

Resources are limited (scarce) when their supply is less than the total demand for them, so not every want can be satisfied. Scarcity is relative: it compares what is available with what is wanted. It does not mean a resource is rare in absolute terms.

Examples:
1. Land: the area of a country is fixed, but it is wanted for farming, housing, factories and roads.
2. Water: a town's reservoir must supply homes, farms and industry.
3. Money: a family's income is limited compared with its wants.
4. Time: a student has 24 hours for study, sleep, play and travel.
5. Fossil fuels: coal and petroleum are being used up.

Even rich countries face scarcity, because wants grow as incomes grow.

Worked example

(2 marks) 'Even a rich country faces scarcity.' Explain.

Try it first, then show the solutionSolution

1. Scarcity means resources are limited relative to wants, not that a country is poor - 1 mark.
2. As incomes rise, wants expand (better health care, new technology, cleaner environment), so resources remain short of wants - 1 mark.

Answer: Scarcity is relative: it compares resources with wants. A rich country has more resources, but its wants grow too, so it still cannot satisfy all of them and must choose.

The basic economic problem

The basic economic problem is the problem of choice that arises because human wants are unlimited while the resources to satisfy them are limited and have alternative uses.

Three facts create it:
1. Unlimited wants: as one want is satisfied, another arises; wants also recur.
2. Limited (scarce) resources.
3. Alternative uses: a resource can be used in more than one way. A plot of land can grow wheat or vegetables, or hold a school; ₹1,000 can buy books or a cricket bat.

Because of these, every person, firm and government must choose which wants to satisfy and how to allocate resources. If resources were unlimited, or had only one use, there would be no problem of choice.

When a resource is used for one thing, the next best alternative given up is its opportunity cost: if a farmer grows wheat on a plot that could have grown vegetables, the vegetables forgone are the cost of the wheat.

Worked example

(2 marks) Why would there be no economic problem if resources had only one use?

Try it first, then show the solutionSolution

1. The economic problem is a problem of choice between uses - 1 mark.
2. If a resource had only one use, there would be nothing to choose between, so no problem of allocation would arise - 1 mark.

Answer: The problem of choice exists because scarce resources can be put to different uses. With only one possible use, there is no decision to make about allocating them, so the basic economic problem would not arise.

Need for efficient use of resources

Since resources are limited, they must be used efficiently: getting the maximum output and satisfaction from given resources, with the least waste, and keeping enough for the future.

Why it is needed:
1. To satisfy as many wants as possible from limited resources.
2. To raise output and incomes, and so reduce poverty.
3. To conserve non-renewable resources for future generations (sustainable development).
4. To reduce pollution and waste.

Example: drip irrigation gives water directly to the roots of plants, so a farmer can irrigate the same field with much less water than flood irrigation and use the water saved on another field. Other examples: LED bulbs, recycling paper, repairing machines, car-pooling.

Worked example

(2 marks) Explain the need for efficient use of resources with an example.

Try it first, then show the solutionSolution

1. Resources are limited relative to wants, so wasting them leaves wants unsatisfied; efficient use gets the most output from given resources - 1 mark.
2. Example: drip irrigation saves water compared with flooding the field, so more land can be irrigated with the same water - 1 mark.

Answer: Because resources are scarce, using them without waste lets more wants be satisfied and conserves them for the future. For example, a farmer using drip irrigation waters his field with much less water than flood irrigation and can use the saving on another plot.

Central problem 1: What to produce (and how much)

The economy must decide which goods and services to produce and in what quantities, because it cannot produce everything. This includes choices between:
1. Consumer goods (food, clothes) and capital goods (machines, roads).
2. Necessities and luxuries.
3. Civil goods and defence goods.
4. Present consumption and future growth.

Example: a government with a limited budget must decide whether to build more hospitals or more highways; a farmer must decide whether to grow wheat or sugarcane. Producing more of one means producing less of another.

Worked example

(2 marks) Explain the problem of 'what to produce' with an example.

Try it first, then show the solutionSolution

1. Because resources are limited, the economy must choose which goods to produce and how much of each - 1 mark.
2. Example: choosing between more food grains (consumer goods) and more tractors (capital goods) - 1 mark.

Answer: With limited resources an economy cannot produce everything, so it must decide which goods and how much of each to produce, for example whether to use resources for food grains for today or for tractors that raise future output.

Central problems 2 and 3: How to produce and for whom to produce

How to produce: the choice of technique of production, that is, the combination of factors to be used.
1. Labour-intensive technique: more labour, less capital, such as handloom weaving or hand harvesting. Suits a country with plenty of cheap labour, and creates jobs.
2. Capital-intensive technique: more machines, less labour, such as power looms or combine harvesters. Gives large output and uniform quality, and suits a country with plenty of capital.
The aim is to use the technique that gives the output at the lowest cost while making the best use of the factors the country has.

For whom to produce: the problem of distributing the output (or national income) among the people: who gets how much. It depends on how income is shared among the owners of the factors of production (wages, rent, interest, profit) and among rich and poor. Example: should a government provide subsidised food grains for the poor through a public distribution system, or let all grain be sold at market price? Should luxury cars or affordable buses be produced?

Capitalist economies solve all three problems mainly through the price mechanism; socialist economies through central planning; mixed economies such as India through both.

Worked example

(2 marks) Distinguish between labour-intensive and capital-intensive techniques with one example each.

Try it first, then show the solutionSolution

1. Labour-intensive: more labour and less capital per unit of output, e.g. handloom weaving - 1 mark.
2. Capital-intensive: more machines and less labour per unit of output, e.g. a power loom factory - 1 mark.

Answer: A labour-intensive technique uses relatively more workers and fewer machines (handloom weaving); a capital-intensive technique uses relatively more machines and fewer workers (power loom mill).

Problems of an Economy: key facts

Basic economic problem

Unlimited wants + limited resources + alternative uses = problem of choice

All three are needed.

Types of resources

Natural (renewable, non-renewable), human, capital (man-made)

Central problems

What to produce (and how much); How to produce (technique); For whom to produce (distribution)

Cost of a technique

Total cost = (number of workers × wage) + cost of capital used

Opportunity cost

Opportunity cost = value of the next best alternative given up

Helps explain alternative uses.

Who solves them

Capitalist: price mechanism; Socialist: central planning; Mixed: both

Where students lose marks in Problems of an Economy

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

• ✗Mistake: Leaving out 'alternative uses'

  The basic problem needs all three facts; without alternative uses there is no choice.

  Wrong working

  'The economic problem arises because wants are unlimited and resources are limited.'

  Right working

  '…and resources are limited and have alternative uses, so choice is necessary.'

  ✓Do this: Write U-L-A every time.

  Usually costs: 1 mark.

• ✗Mistake: Defining scarcity as 'shortage' or 'rarity'

  Scarcity is relative to wants; a resource can be plentiful yet scarce.

  ✓Do this: Say 'limited in relation to the wants for it'.

  Usually costs: 1 mark.

• ✗Mistake: Explaining 'how to produce' as 'how much to produce'

  How to produce is about technique; how much belongs with 'what to produce'.

  ✓Do this: How = technique (labour- or capital-intensive).

  Usually costs: 1 mark.

• ✗Mistake: Central problems without examples

  The syllabus asks for a brief understanding with examples.

  ✓Do this: One concrete example under each problem.

  Usually costs: Up to half the marks.

• ✗Mistake: Forgetting the capital cost in technique numericals

  Students compare wages only.

  ✓Do this: Total cost = workers × wage + capital cost.

  Usually costs: The calculation mark.

1. Q1 · 1 mark · MCQExam level

   The basic economic problem arises because:
   (a) resources are unlimited
   (b) wants are limited
   (c) wants are unlimited and resources are limited with alternative uses
   (d) prices are high

   Hint

   U-L-A.

   Answer

   (c) wants are unlimited and resources are limited with alternative uses.

2. Q2 · 1 mark · MCQExam level

   Which of these is a capital (man-made) resource?
   (a) A river
   (b) A dam
   (c) A teacher
   (d) Iron ore

   Hint

   Made by people to help production.

   Answer

   (b) A dam.

3. Q3 · 2 marks · Very short answerExam level

   Distinguish between renewable and non-renewable resources with one example each.

   Hint

   Can nature replace it?

   Answer

   Renewable resources are replenished naturally over time (forests, solar energy). Non-renewable resources have a fixed stock that cannot be replaced once used up in human time (coal, petroleum).

4. Q4 · 2 marks · Very short answerHarder exam level

   'Scarcity is a relative concept.' Explain.

   Hint

   Relative to wants.

   Answer

   Scarcity compares the supply of a resource with the demand for it. A resource may be large in quantity yet scarce if demand is larger; it is not about being rare in absolute terms.

5. Q5 · 2 marks · Short answerHarder exam level

   Give one example each of a 'what', 'how' and 'for whom' decision faced by a school.

   Hint

   Think of the school as a small economy.

   Answer

   What: whether to spend the budget on a science laboratory or a library. How: teach computers with one computer per student or with a shared computer lab and projector. For whom: whether to offer fee concessions to students from poor families.

6. Q6 · 2 marks · Very short answerHarder exam level

   Why are human resources called the most important resource?

   Hint

   They use the others.

   Answer

   Because natural and capital resources become productive only when people with skills and knowledge use them; skilled, healthy people can also discover and create new resources.

7. Q7 · 2 marks · Short answerHarder exam level

   A factory can make 1,000 bags either by hand (40 workers at ₹400 a day, ₹2,000 of tools) or by machine (8 workers at ₹400 a day, ₹12,000 of machine cost). Which technique is cheaper, and by how much?

   Hint

   Workers × wage + capital cost.

   Answer

   By hand: 40 × 400 + 2,000 = ₹18,000. By machine: 8 × 400 + 12,000 = ₹15,200. The machine (capital-intensive) technique is cheaper by ₹2,800.

8. Q8 · 2 marks · Short answerHOTS / competency

   In the bag factory above, at what daily wage would both techniques cost the same?

   Hint

   40w + 2,000 = 8w + 12,000.

   Answer

   40w + 2,000 = 8w + 12,000, so 32w = 10,000 and w = ₹312.50. Below this wage the hand technique is cheaper; above it the machine technique is cheaper.

9. Q9 · 5 marks · Long answerHOTS / competency

   'Choice is the essence of economics.' Discuss with reference to the basic economic problem and the central problems.

   Hint

   Why choice arises; where it is made.

   Answer

   Choice is needed because wants are unlimited while resources are limited and have alternative uses (the basic economic problem). Every economy must therefore choose (1) what to produce and in what quantities, (2) how to produce, labour- or capital-intensive, and (3) for whom to produce, i.e. how output is shared. Households (budgets), firms (products and techniques) and governments (spending and welfare) all face these choices, and the way they are made (market, plan or both) defines the type of economy. So economics is essentially the study of how choices are made under scarcity.
