Also known as laissez-faire economies, where governments leave markets to their own devices, so the market forces of supply and demand allocate scarce resources
Free market economies
Economic decisions are taken by private individuals and firms, and private individuals own everything. There is no government intervention
In reality, governments usually intervene by implementing laws and public services, such as property rights and national defence
Adam Smith
Famous free market economist, developed the theory of the invisible hand of the market
Friedrich Hayek
Famous free market economist, argued that government intervention makes the market worse
How prices are determined in free market economies
Prices are determined by the 'spending votes' of consumers and businesses
Adam Smith recognised some of the issues with monopoly power that could arise from a free market
Hayek argued that the Fed caused the 1930s crash by keeping interest rates low and encouraging 'malinvestments'
What is determined in a free market economy
What to produce: determined by what the consumer prefers
How to produce it: producers seek profits
For whom to produce it: whoever has the greatest purchasing power in the economy, and is therefore able to buy the good
Advantages of free market economies
Firms are likely to be efficient because they have to provide goods and services demanded by consumers. They are also likely to lower their average costs and make better use of scarce resources. Therefore, overall output of the economy increases
The bureaucracy from government intervention is avoided
Some economists might argue the freedom gained from having a free economy leads to more personal freedom
Disadvantages of free market economies
The free market ignores inequality, and tends to benefit those who hold most of the wealth. There are no social security payments for those on low incomes
There could be monopolies, which could exploit the market by charging higher prices
There could be the overconsumption of demerit goods, which have large negative externalities, such as tobacco
Public goods are not provided in a free market, such as national defence. Merit goods, such as education, are underprovided
Command economy
This is where the government allocates all of the scarce resources in an economy to where they think there is a greater need. It is also referred to as central planning
Karl Marx
Saw the free market as unstable and argued for the "common ownership of the means of production"
What is determined in a command economy
What to produce: determined by what the government prefers
How to produce it: governments and their employees
For whom to produce it: who the government prefers
Advantages of command economies
It might be easier to coordinate resources in times of crises, such as wars
The government can compensate for market failure, by reallocating resources. They might ensure everyone can access basic necessities
Inequality in society could be reduced, and society might maximise welfare rather than profit
The abuse of monopoly power could be prevented
Disadvantages of command economies
Governments fail, as do markets, and they may not be fully informed for what to produce
They may not necessarily meet consumer preferences
It limits democracy and personal freedom
Mixed economy
This has features of both command and free economies and is the most common economic system today. There are different balances between command and free economies in reality
The market is controlled by both the government and the forces of supply and demand
Governments often provide public goods such as street lights, roads and the police, and merit goods, such as healthcare and education
What is determined in a mixed economy
What to produce: determined by both consumer and government preferences
How to produce it: determined by producers making profits and the government
For whom to produce it: both who the government prefers and the purchasing power of private individuals
