Cambridge IGCSE Economics 0455
Syllabus points
- Define the market economic system.
- Explain its advantages and disadvantages.
What is a market economy?
In a market economic system (also called a free-market or capitalist economy), resources are owned privately and allocated by the price mechanism — the interaction of demand and supply — with little or no government involvement. Firms produce what is profitable, and consumers vote with their money.
Key definitions
| Term | Definition |
|---|---|
| Market economy | An economy where resources are allocated by the price mechanism with minimal government involvement. |
| Private sector | Firms and individuals owning resources and producing for profit. |
Advantages
- Efficiency — competition pushes firms to keep costs and prices low.
- Choice — firms produce a wide variety of goods consumers want.
- Incentives — the chance of profit encourages hard work, enterprise and innovation.
- Automatic allocation — prices adjust quickly to changes in demand and supply.
Disadvantages
- Market failure — markets ignore external costs (like pollution) and under-provide public goods.
- Inequality — income depends on what you own and can sell, so some people are left with very little.
- Monopoly power — successful firms may dominate and exploit consumers.
- Instability — free markets can experience booms and slumps.
The market is efficient and responsive, but it can be unfair and can fail to consider costs to society.
Worked example
In a market economy, if consumers start demanding electric cars, their price rises, profits attract firms, and resources shift into making them — quickly and without any government plan. But the same market ignores the pollution from producing them and may leave low-income households unable to afford any car at all, showing the system's weaknesses.
Common exam mistakes
- Saying a market economy has *no* problems — always give disadvantages too.
- Confusing "market" (private, price-led) with "planned" (government-led).
Exam technique
Balance advantages and disadvantages, and use market failure and inequality as the key criticisms that justify some government intervention (leading to the mixed economy, topic 2.11).
Quick revision
