# Scarcity, Opportunity Cost and the Production Frontier

Wants run ahead of what the available time, money and land can make, so every choice gives up the next best use of the same resources. A production frontier draws that trade-off for a whole economy: points inside waste resources, points outside are out of reach, and moving along the curve costs some of the other good.

## Ready when they can

- State the opportunity cost of a decision as the single best alternative given up, not the whole list of things not chosen
- Read a production frontier: name a point that wastes resources, a point that is unreachable, and the cost of moving along the curve
- Explain why the frontier bends instead of running straight (resources are not equally suited to both jobs)

## Lesson: Choosing costs something

Economics starts with scarcity: human wants for goods, services and resources run past what is available. Labour, tools, land and raw materials all sit in limited supply, and time is the scarcest of all, with just 24 hours a day for everyone. Every choice therefore gives up something else.

**Example.** Study an hour and you spend an hour of gaming, so the gaming hour is the opportunity cost. A government putting an extra billion into hospitals pays the best other use of that billion, perhaps highways. Opportunity cost is always that single best alternative given up, never the whole list.

A production frontier draws the trade-off for a whole economy making two goods. Points inside the curve waste resources, points outside sit out of reach, and moving along the curve costs some of the other good. The curve bends instead of running straight because resources are not equally suited to both jobs.

**Tip.** Name costs honestly. More resources, better tech or stronger skills can push the whole frontier outward.

**Recap.** Scarcity forces choice, choice carries an opportunity cost, and the frontier maps the trade.
