Economic Systems: Market & Mixed
Allocation of Resources
A mixed economic system is one in which both the private sector and the public sector (government) allocate resources. Most goods and services are left to the market, but the government intervenes where the market on its own would fail.
The mixed economy is the most common real-world system; almost every country is a mixed economy of some kind. The balance varies: some governments intervene heavily, others lightly.
In a mixed economy:
- The private sector / private firms produce most goods and services through the price mechanism, motivated by profit.
- The public sector / government provides goods the market under-supplies (public goods, merit goods), redistributes income through taxes and benefits, and regulates the harmful side-effects of private activity.
Common exam question
Identifying what makes an economy mixed
Question: Identify who allocates resources in a mixed economy, or give two reasons why a country in the source counts as a mixed economy (2 marks).
Asked in 2 of the 11 structured papers. The marks go one to each sector, so name both: the private sector (private firms, or firms and producers) and the public sector (the government, or state-owned and nationalised firms). With a source, use it: public-sector jobs, output from state-owned firms or a government intervention it describes all earn the public-sector mark, and you still need the separate point that a private sector exists.
The same idea is set in 1 of the 13 multiple-choice papers, which asks for the pair of services the private sector would most likely provide. Choose services firms can sell at a profit, such as banking and insurance; courts, prisons, tax collection and defence are provided by the government.
The government intervenes for several reasons: to correct market failure, to support firms, to promote equity, to support poorer households, and to collect government revenue.
Arguments for the mixed economic system
- Keeps the strengths of the market. Competition, choice, the profit incentive and efficiency are retained for most goods.
- Corrects market failure. The government provides public goods and merit goods, taxes goods with external costs, and subsidises goods with external benefits.
- Reduces poverty and inequality. Taxation and welfare benefits redistribute income; state healthcare and education give the poor access to essential services.
- Greater stability. The government can use policy to smooth booms and recessions.
Arguments against the mixed economic system
- Higher taxes. Government spending must be funded, so taxes reduce the incentive to work and invest.
- Inefficiency in the public sector. State-run organisations face no competition and may have weaker incentives to keep costs down.
- Risk of government failure. Intervention can be poorly designed; the cost of correcting a market failure can end up larger than the failure itself.
- Bureaucracy. Regulation and administration can slow firms down and add to their costs.
Common exam question
Discussing whether government intervention works
Question: Discuss whether or not intervention by the government can overcome the weaknesses of a market economy, or whether it benefits firms (8 marks).
Asked in 2 of the 11 structured papers. For intervention: the government can provide merit goods and public goods, restrict demerit goods, regulate monopolies or block mergers, tackle external costs such as pollution, and help people on low incomes. A regulation can ban a product, limit purchases or set an age limit, cutting harmful consumption and external costs. Firms gain from subsidies and tax cuts that lower costs.
Against: government failure, as governments can lack accurate information, decide slowly, weaken incentives or suffer corruption. Regulations, taxes and a minimum wage can raise firms' costs and cut profits. A ban can be hard to police and may create illegal markets, policing has an opportunity cost, and jobs, output and tax revenue from the industry can fall. Level 3 (6–8 marks) needs both sides developed.
