A fourth instance of market failure relates to the supply of public goods. Some types of goods and services are seen as socially desirable or beneficial and are so important that everybody should be able to use them, even if they are poor and cannot afford to pay for them. Here we might think of services including education, health, energy, housing, transport and communications. However, these goods and services are costly to produce or run. They cannot therefore normally be sold cheaply at a lower price so that everyone can afford them, otherwise firms producing these services would be unable to make good profits (

The government has therefore been forced to take on the main responsibility for providing public goods and services such as free education, low cost housing and affordable healthcare.
