What is a market economy?

• A. An economic system where prices and production are determined by supply and demand.
• B. An economy controlled entirely by the government.
• C. An economy based on barter only.
• D. An economy with no production.

Answer: (A)

In a market economy, prices and production are guided by what buyers want and what sellers provide. Prices act as signals: if a good is in high demand and scarce, its price rises, encouraging producers to make more; if demand falls, prices drop and production may slow. This creates a cycle where resources flow toward things people want and are willing to pay for, and away from things that aren’t worth the cost to produce.

People trade money for goods and services, and competition among businesses helps keep prices fair and quality up. Government involvement exists, but it doesn’t set what’s produced or at what price; instead, it enforces laws, protects property rights, and may provide public goods or stabilizing measures.

The other ideas don’t fit a market economy because they describe systems where production and prices are set by the government, or where money isn’t used at all, or where nothing is produced.
