The Signalling Function
Price signal info that allows buyers and sellers in a market to plan and coordinate their economic activities. Prices fall and rise to reflect scarcities and surpluses. if prices rise due to increased demand this signals suppliers to expand production.
The Rationing Function
An increase in price gets rid of excess demand, the rising price reflects the strength of consumer preferences and consumers ability to pay. This function distributes scarce goods to consumers who value them highly.
The Incentive Function
Prices create incentives for people to alter their economic behavior. A higher price creates an incentive for firms to supply more because they believe higher profits can be made.

Excludable Definition
The owners can exercise the private property rights, preventing other people from using the good or consuming its benefits.
Rival Definition
If someone consumes the good, then no one else can consume it and gain its benefits.
Non-excludability Definition
The benefits derived from pure public goods cannot be confined solely to those who have paid for it.
Non-rivalry Definition
Consumption by one consumer does not restrict consumption by other consumers.
Free Rider Problem
Because public goods are non-excludable it is difficult to charge people for benefiting from a good or service once it is provided. This leads to under provision of a good and thus causes market failure.
Quasi-Public Goods Definition
A good which is not fully non rival and/or where it is possible to exclude people from consuming the product.
Semi Non-Excludable Definition
It is possible but often difficult or expensive to exclude non paying customers.
Technological Change
Made it easier for the government or local authorities to reduce the free rider problem. Roads used to be a pure public good where it was impractical to charge motorists for the use of the roads, due to technical change governments and local authorities have been able to use electronic pricing to charge motorists. Roads are a quasi-public good.

Why does the government provide merit goods and services?
