Types of Economic System
An economic system determines how an economy answers the three basic economic questions: what to produce, how to produce it, and for whom.
The three systems
- Market economy: resources are allocated by the price mechanism (supply and demand), with little government intervention. Firms and consumers make decisions freely.
- Planned economy: the government owns resources and decides what, how, and for whom to produce.
- Mixed economy: combines market forces with government intervention — most real-world economies fall here, just at different points on the spectrum.
Worked example
Question: Explain one advantage of a market economy over a planned economy.
Answer: In a market economy, resources are allocated efficiently because firms respond directly to consumer demand through the price mechanism — if demand for a good rises, its price rises, incentivising firms to produce more of it. A planned economy relies on central decisions, which can be slower to react and may not reflect what consumers actually want.
Common mistake: describing a mixed economy as 50% market, 50% planned. It just means both market forces and government intervention exist together, not a fixed split.
