Economic Systems: Market & Mixed
Allocation of Resources
A market economic system is one in which resources are allocated by the , through the free interaction of demand and supply, with little or no . Firms are privately owned and produce whatever is profitable; consumers spend their own incomes as they choose.
In a pure market system the government plays almost no role in production. The three questions are answered automatically by prices (topic 6):
- What to produce? Whatever consumers are willing to pay for. High prices signal high demand, so firms produce it.
- How to produce? In the cheapest way, because firms compete and the lowest-cost producer earns the most profit.
- For whom to produce? For those willing and able to pay the market price.
The driving forces are private ownership, the profit motive, and competition between firms.
Common exam question
Recognising a market economy in multiple choice
Question: Pick the feature that defines a market economy, something that could or could not happen in one, or one of its advantages or disadvantages (1 mark, multiple choice).
Set in 5 of the 13 multiple-choice papers. A market economy means private ownership of the factors of production and resources allocated through demand and supply, with no government allocation. So an option in which the government acts (a minimum wage, public ownership, more nationalisation, "state intervention") cannot describe it, while a monopoly, heavy pollution and private firms making defence equipment can all occur in one.
Limited resources with unlimited wants is scarcity, true of every economy, and having both a private and a public sector is a mixed economy. The credited advantage is lower costs of production; less inequality and more public goods come from government. The credited disadvantage is too few merit goods; competition and choice are market features, not things it lacks.
Arguments for the market economic system
- Efficiency. Competition forces firms to keep costs and prices low; inefficient firms lose customers and leave the market.
- Responsiveness to consumers. Prices act as signals, so resources flow quickly to the goods consumers most want. This is sometimes called consumer sovereignty.
- Incentives and choice. The profit motive rewards firms that innovate and work hard, and consumers enjoy a wide variety of goods produced by competing firms.
- Economic growth. The pursuit of profit encourages investment and the development of new products, which can raise output over time.
Arguments against the market economic system
- Market failure. A pure market over-produces goods with external costs (pollution) and under-provides merit goods and public goods (the free market may not provide defence or street lighting at all).
- Income inequality and poverty. Resources go only to those who can pay. People on low incomes, the unemployed and those unable to work may be left without essentials, and there are no automatic welfare benefits.
- Monopoly. Successful firms can grow until they dominate a market, then restrict supply and raise prices at the expense of consumers.
- Instability. Markets can swing between booms and recessions with no one to smooth them out.
Common exam question
Discussing how well a market economy works
Question: Discuss whether or not a market economy gives the best possible allocation of resources, or whether a high level of poverty is likely in a market economic system (8 marks).
Asked in 2 of the 11 structured papers. For the market: prices follow demand and supply, moving resources towards the goods people want more; the profit incentive makes firms produce what consumers want (consumer sovereignty); competition brings efficiency and lower prices; and wage changes draw workers to the jobs most needed. For poverty, add high wages and jobs from efficiency, growth from responding to demand, and relative poverty coexisting with little absolute poverty.
Against: merit goods such as healthcare and education are under-consumed, demerit goods over-consumed, public goods not provided, external costs and benefits ignored, and monopolies can restrict output and raise prices. For poverty, add unemployment, no welfare benefits and income inequality. Level 3 (6–8 marks) needs both sides developed; one-sided answers fit Level 2 (3–5 marks).
