OCR GCSE Economics: Economic groups, factors of production and scarcity (J205)

This guide covers sections 1.1 and 1.2 of the OCR GCSE (9-1) Economics specification (J205), version 2.0, for first assessment in 2019. They sit in component J205/01, Introduction to Economics, a written paper of 80 marks and 1 hour 30 minutes worth 50% of the qualification. J205 has no tiers, so every candidate learns the same content. Each number in the worked examples is made up for illustration.

Where next: revision notes, practice questions, the broader Introduction to Economics guide, the course hub, the checklist and the free diagnostics if you want to find your weak spots.

1.1 The main economic groups

Consumers are the people (individually or as households) who buy goods and services to satisfy their wants. They also supply labour to firms and pay taxes.

Producers are the firms and other organisations that make goods and provide services. They combine factors of production, employ workers, and usually aim to earn a profit.

The government collects taxes, spends them on public services such as roads, schools and health care, passes laws that firms and consumers must follow, and can redistribute income through benefits.

Interdependence

No group can act alone. Follow the chain:

1. Households supply labour (and sometimes land or savings) to firms.
2. Firms pay wages, rent, interest and profit to households.
3. Households spend that income on what firms produce.
4. Firms and households pay taxes to the government.
5. The government spends the revenue on services and infrastructure that both groups use.

Break the chain at any point and the others are affected. Suppose the government raises the tax on firms’ profits. Firms may cut investment or jobs; households then have less income; they spend less; firms sell less; and tax revenue can fall. Equally, a government that cuts taxes may leave more income with households and firms, yet have less to spend on the roads and schools those same groups rely on.

Evaluation point: the size of the effect depends on how far firms can pass the tax on, how long it lasts, and what the government does with the money. A tax that funds better training could help firms later, even if it hurts them now.

1.1 The factors of production

Factor	Meaning	Examples (a bakery)	Usual reward
Land	Natural resources and the space they occupy	The rented unit, flour from farmland, water	Rent
Labour	Human effort, physical and mental	Bakers, delivery drivers	Wages
Capital	Man-made goods used in making other goods	Ovens, mixers, the delivery van	Interest
Enterprise	Organising the other factors and bearing the risk	The owner who starts the business	Profit

In economics, capital means productive equipment, not money. Money used to buy machinery is finance, not a factor of production.

Combining the factors

Output depends on the mix. A labour-intensive method uses many workers and little equipment. A capital-intensive method uses machines and few workers. The choice depends on the relative cost of each factor, the product, the scale of output and the skills available.

Worked example (invented). Oakfield Print Shop makes boxes of greetings cards. Workers earn £80 a day.

	Method 1: hand presses	Method 2: printing machine
Workers	12	4
Tool or machine cost per day	£60	£300
Output per day	60 boxes	100 boxes

Output per worker: Method 1 = 60 ÷ 12 = 5 boxes. Method 2 = 100 ÷ 4 = 25 boxes.

Daily cost: Method 1 = 12 × £80 + £60 = £1,020. Method 2 = 4 × £80 + £300 = £620.

Cost per box: Method 1 = £1,020 ÷ 60 = £17.00. Method 2 = £620 ÷ 100 = £6.20.

Method 2 is cheaper per box. If the daily wage rose to £120, Method 1 would cost 12 × £120 + £60 = £1,500, or £25.00 a box, and Method 2 would cost 4 × £120 + £300 = £780, or £7.80 a box. A wage rise widens the gap, because Method 1 uses more labour.

Evaluation: Method 2 is not automatically best. If demand is uncertain, the machine’s fixed cost is risky. Eight workers lose their jobs, which is a social cost. The enterprise factor (the owner) bears that decision and its risk.

1.2 Scarce resources and unlimited wants

Resources are scarce: there is not enough land, labour, capital and enterprise to produce everything people would like. Wants are unlimited: when one want is met, another appears. Scarcity is therefore a permanent feature of every economy, rich or poor. It is not the same as a shortage of one product on one day.

The economic problem

Because resources are scarce, every society must choose. The questions are:

• What goods and services should be produced (more hospitals or more roads, more food or more cars)?
• How should they be produced (labour-intensive or capital-intensive methods, which materials, how much energy)?
• For whom should they be produced (who gets them, and how is income shared)?
• How should resources be allocated between all these uses, and who decides: markets, the government, or a mix?

Worked example (invented). Island A uses all its resources to produce rice and fish, in thousand tonnes.

Option	Rice	Fish
P	0	60
Q	10	56
R	20	48
S	30	36
T	40	20
U	50	0

This table is a teaching aid, not a diagram the specification names. It shows that the island cannot have more of both. Choosing S answers “what” (30 rice, 36 fish). Each move to the right answers it differently.

Opportunity cost

Opportunity cost is the loss you accept when you choose one thing over the second-best thing you could have had. It is the one best alternative forgone, not a total of everything you could have done.

Example 1. A student has £40. The options, in order of preference, are a concert ticket (£40), trainers (£35) and a game (£25). She buys the ticket. Her opportunity cost is the trainers, not the trainers plus the game.

Example 2 (from the table). Moving from P to Q costs 60 − 56 = 4 fish for 10 rice. Q to R costs 8, R to S costs 12, S to T costs 16, T to U costs 20. Opportunity cost per 10 rice rises: 4, 8, 12, 16, 20. Resources moved later are worse suited to rice.

Example 3. A council has £60 million. Its ranking is: bypass, health clinic, sports centre. It builds the bypass, so the opportunity cost is the clinic.

Opportunity cost applies to consumers (time and money), producers (what else the factors could make) and governments (other uses of tax revenue).

Evaluating economic choices and sustainability

Evaluate by listing costs and benefits, deciding who gains and loses, how big and how long-lasting each effect is, and then reaching a justified judgement. Three types of sustainability matter:

• Economic: can the activity keep producing income and jobs over time?
• Social: does it support well-being, fairness and communities, now and for later generations?
• Environmental: does it protect resources, wildlife and the climate, or use them up?

Worked example (invented). The council of Lowmoor owns 40 hectares of unused land and has three options.

	Solar farm	Housing	Nature park
Money	Cost £8.0m; income £0.9m a year for 25 years	Developer pays £4.5m for the land	Cost £1.2m; running cost £0.10m, café income £0.05m a year
Economic	Payback £8.0m ÷ £0.9m = 8.9 years; net £0.9m × 25 − £8.0m = £14.5m	One-off £4.5m; 90 building jobs for 2 years	Net cost over 25 years: £1.2m + 25 × £0.05m = £2.45m; 2 jobs
Social	6 jobs; cheaper energy	150 homes; more traffic and school demand	Recreation and health benefits
Environmental	Clean energy; panels to recycle	Green space lost	Biodiversity and flood protection

The developer’s figures are consistent: 150 homes at £210,000 earn £31.5m, against £25.5m of building costs plus £4.5m for the land, leaving a £1.5m profit.

Judgement. The solar farm earns the most over time and is environmentally friendly, but it needs £8.0m up front. Housing gives a quick payment and meets a social need, but it uses the land up for good. The park costs money, yet its benefits are hard to price. A reasoned conclusion might back solar on part of the land, because it sustains income and the environment, while saying the answer depends on whether the council values income or housing more. Always name what you gave up: that is the opportunity cost.

Common errors

• Defining capital as money.
• Giving a list of alternatives as the opportunity cost instead of the best one.
• Treating scarcity as a shortage of one product.
• Listing costs and benefits without a judgement.
• Mentioning sustainability in one word without saying which type or why.
