The basic economic problem of scarcity, the need for choice, opportunity cost as the next best alternative given up, and the four factors of production.

What this dot point is asking

The SQA wants you to explain the basic economic problem, why scarcity forces individuals, firms and governments to make choices, what opportunity cost means, and the four factors of production used to make goods and services.

Scarcity: the root of economics

Economics exists because of one stubborn fact. The resources available to make goods and services - workers, land, factories, raw materials - are finite, but human wants are unlimited. People always want more, better or newer things than the available resources can provide. This gap between limited resources and unlimited wants is scarcity, and it applies to individuals, firms and the government alike.

It is important to separate a want from a need. A need is something essential for survival, such as food, water and shelter. A want is something desired but not essential, such as a holiday or a games console. The economic problem covers both, because even basic needs compete for the same scarce resources.

Choice and the three questions

Because resources are scarce, no economy can produce everything. It must choose. Economists summarise the choices every economy faces as three questions: what to produce, how to produce it, and for whom to produce it. A decision to use steel and workers to build hospitals is also a decision not to use them for something else, so choosing is unavoidable.

Opportunity cost

Every choice has a hidden price. When you pick one option, you give up the chance to have the next best thing. That sacrificed alternative is the opportunity cost of the decision.

Opportunity cost runs through every level of the economy:

• A consumer who spends £40 on a concert ticket gives up the clothes that £40 could have bought.
• A firm that uses a factory to make cars cannot use the same factory to make vans at the same time.
• A government that spends an extra £1 billion on defence cannot spend that £1 billion on schools.

The four factors of production

To make any good or service, an economy combines four factors of production. Each earns a reward.

The entrepreneur supplies enterprise. They spot a gap in the market, gather the land, labour and capital, take the financial risk, and keep any profit (or bear any loss). Without enterprise, the other three factors would not be brought together to produce anything.

Why this matters across the course

The basic economic problem is the foundation of everything else in National 5 Economics. Demand and supply are the market's answer to what and for whom to produce. The factors of production reappear when firms calculate costs. Government objectives such as economic growth are really attempts to ease scarcity by producing more from the same resources. Get this dot point secure and the rest of the course has a frame to hang on.
