Scarcity means no economy can produce everything, so every society must answer three fundamental questions about how to use its limited resources.
What to produce?
An economy must decide which goods and services to make, and in what quantities. Should scarce resources go towards food, housing, schools or entertainment? Producing more of one thing means producing less of another, so this question is really about opportunity cost. For example, using more land for houses means there is less land left over for farming and growing food.
How to produce?
Once we know what to produce, we must decide the method. Should a good be made using a lot of labour (labour-intensive) or a lot of machinery (capital-intensive)?
- A small tailor may sew clothes by hand (labour-intensive).
- A large factory may use automated machines (capital-intensive).
The best method depends on costs, the resources available and the scale of production.
For whom to produce?
Finally, an economy must decide how output is shared out among people. Who gets the goods and services produced? This is the question of distribution. In some economies, those with higher incomes can buy more; in others, the government shares output more equally. This raises questions of fairness and incentives that economists often debate. Sharing output very equally may feel fair, but some argue it weakens the reward for hard work; letting the market decide may reward effort and skill, but can leave the poorest with very little. There is rarely one answer that everyone accepts as best.
Different systems, different answers
| System | Who mainly decides |
|---|---|
| Market economy | Buyers and sellers through prices |
| Planned economy | The government |
| Mixed economy | Both the market and the government |
Every economy must answer all three questions; the difference lies in who makes the decisions.
