Mixed economy

  • A mixed economy means that part of the economy is left to the free market, and part of it is run by the government.
  • In reality most economies are mixed, with varying degrees of state intervention.
  • Mixed economies start from the basis of allowing private enterprise to run most business. Then the governments intervene in certain areas of the economy, such as regulation, and spending money on public services.

Examples of mixed economies

Share of government spending as a % of GDP

All the above economies are mixed. Some of economy is managed by the government, the rest left to private firms and individuals.

However, there are different degrees of state intervention. European economies such as Sweden and France have a generous level of social security spending. Education and health care are free at the point of US. In the US, government spending as a share of GDP is lower, but health care has to be paid for.

As economies develop, the government often take a higher share of total spending. Developed countries, such as in Western Europe, often choose to provide state welfare support, and greater government regulation of the environment and business environment.

Advantages of mixed economies

  • Most business and industry can be left to private firms. Private firms tend to be more efficient than government controlled firms because they have a profit incentive to cut costs and be innovative.
  • Mixed economies can reduce the amount of government regulation and government control prevalent in a command economy.
  • Mixed economies can enable some government regulation in areas where there is market failure. This can include:
    • Regulation on the abuse of monopoly power, e.g. prevent mergers, prevent excessively high prices.
    • Taxation and regulation of goods with negative externalities, e.g. pollution,
    • Subsidy or state support for goods and services which tend to be under consumed in a free market. This can include public goods, like police and national defence, and merit goods like education and health care.
  • A mixed economy can create greater equality and provide a ‘safety net’ to prevent people living in absolute poverty. At the same time, a mixed economy can enable people to enjoy the financial rewards of hard work and entrepreneurship.
  • Government can pursue policies to provide macro-economic stability, e.g. expansionary fiscal policy in times of a recession.

Disadvantages mixed economies

  • Can be difficult to know how much governments should intervene, e.g. discretionary fiscal policy may create alternative problems such as government borrowing.
  • Mixed economies are criticised by socialists for allowing too much market forces, leading to inequality and an inefficient allocation of resources.
  • Mixed economies are criticised by free market economists for allowing too much government intervention. Libertarians argue that governments make very poor managers of the economy, invariably being influenced by political and short-term factors.


  • In reality, it depends how a mixed economy is managed. Even the most ardent market economists argue we need a degree of government intervention – if only to protect private property. For example, Adam Smith in ‘Wealth of Nations’ argued governments needed to prevent the exploitation of monopoly power.
