Government Price Controls

Government price controls are situations where the government sets prices for particular goods and services. This can take various forms such as:

  • Minimum prices – Prices can’t be set lower (but can be set above)
  • Maximum price – Limit to how much prices can be raised (e.g. market rent)
  • Buffer stocks – Where government keep prices within a certain band
  • Limiting price increases – In a privatised monopoly (e.g. electricity, gas, water – where there is no competition) the government regulator may play a role in limiting how much prices can be increased. In the UK, regulators use a formula like RPI-X.
  • Direct price setting – In a command economy, prices of goods may be set by the government.

For various reasons, governments may wish to intervene in a free market to set prices. Usually, prices are set the market forces (where supply and demand differ) But, in some markets, governments may want to artificially set different prices.

Minimum Prices


This is when the government don’t allow prices to go below a certain level. If minimum prices are set above the equilibrium it will cause an increase in prices.

For example, the EU has used minimum prices for agriculture. It is argued farmer’s incomes are too low. Therefore, minimum prices have been used to increase prices above the equilibrium. This enables farmers to get a higher income.

However, the big problem is that this minimum price creates a surplus. Therefore, the government have to purchase the surplus to maintain a minimum price. The Common Agricultural Policy became very expensive because the minimum prices encouraged farmers to supply as much as possible.

Related to minimum prices is the concept of a minimum wage

Maximum Prices


This is when the government wish to prevent prices going above a certain level. If a maximum price is placed below the equilibrium, prices will fall.

But if the price is below the equilibrium, demand will be greater than supply leading to a shortage.

The government may wish to use maximum prices to reduce the cost of renting a house.

The government may also use maximum prices for important food-stuffs or pharmaceutical drugs which it wants to make more affordable.

Buffer stocks


A buffer stock is a price control where the government seeks to keep the price within a certain band. It is effectively combining elements of maximum and minimum prices. The aim is to both stabilise prices (and incomes) for farmers and prevent shortages and high prices. If successful, the government buy surplus in a good harvest and then sell surplus if there is a shortage.

Limiting price increases

In a free-market economy, some industries are natural monopolies (the most efficient number of firms is one). In this case, it is not possible to have effective competition. In the absence of government regulation, the monopoly could charge excessively high prices. As a surrogate for competition, the government regulator can set prices (or limit price increases) to make sure the level of profitability is not excessive.

Regulation of monopolies is often controversial. Consumer groups claim regulators become guilty of ‘regulatory capture’ whilst companies can complain they are starved of funds for investment.

Direct price setting

In a command economy (Communist) the government play an important role in deciding what to produce, how to produce and what prices to charge. In this situation, market forces are ignored and the government set the most ‘socially efficient’ prices.

  2. are there any differences among different industries while government control their prices? what’s the side effect of Government Price Controls? is it only useful in the short time? could you explain a bit? thank you

  3. They should make sure that the price is on the product or can be recognised. We are getting repped of in shops because of this. Its not fair we are paying taxes
