Understanding the Mixed Economic System (Cambridge International IGCSE Economics)
Characteristics of a mixed economic system
-
Any economic system needs to decide how to answer the three fundamental economic questions
- What to produce? More weapons for the military or more schools to educate children?
- Who to produce for? Only those who can afford to pay for it? Or for everyone in society?
- How to produce it? Should more labour be used, or should the economy focus on using technology instead?
-
A mixed economic system is a blend of a market and planned economy
-
Individuals, firms and the government own factors of production and distribute goods or services
-
In reality, almost every country in the world operates as a mixed economic system
-
Some countries have more government intervention than others
- e.g. China has more intervention than the USA
-
The higher the level of government intervention, the more the economy will lean towards operating like a planned economy
-
Why do governments intervene?

To correct market failure
-
In many markets there is a less than optimal allocation of resources from society's point of view
- In maximising their self-interest, firms and individuals will not self-correct this misallocation of resources and there is a role for the government
- Governments often achieve this by influencing the level of production or consumption
To earn government revenue
-
Governments need money to provide essential services and public and merit goods
- Revenue is raised through intervention such as taxation, privatisation, sale of licenses (e.g. 5G licenses), and the sale of goods/services
To promote equity
- To reduce the opportunity gap between the rich and poor
To support firms
- In a global economy, governments choose to support key industries to help them remain competitive
To support poorer households
-
Poverty has multiple impacts on both the individual and the economy
- Intervention seeks to redistribute income (tax the rich and give to the poor) so as to reduce the impact of poverty

Arguments for and against the mixed economic system
-
The majority of economies in the world operate as a mixed economic system
-
The extent to which they are mixed varies
- Some lean more towards the free market
- Other lean more towards a planned economy
The spectrum of economic systems and where certain economies fall based on the degree of government intervention
- North Korea is a planned economy
- The United States, Japan and Singapore are mixed economies but have less government intervention than Norway, Germany or China
Evaluating mixed economies
| Advantages | Disadvantages |
|---|---|
| - Efficient resource allocation - The private sector responds to consumer demand, encouraging innovation and competition - Government addresses market failure - Public goods (e.g. street lighting) and merit goods (e.g. education) are provided where the market would under-provide - Reduces inequality - Governments can redistribute income through taxation and welfare to protect vulnerable groups - Protects consumers and the environment - Laws and regulations can reduce external costs and ensure product safety | - Government failure is possible - Decisions by the state may be inefficient or influenced by politics rather than economics - Higher taxes - To fund public services and welfare, taxes may be high, which can discourage work and investment - Bureaucracy and inefficiency - Public sector organisations may lack profit incentives and become wasteful or slow to respond to change - Risk of reduced innovation - Excessive regulation may limit risk-taking and creativity in the private sector |
