When consumed, a merit good creates positive externalities (an externality being a third party/spill-over effect of the consumption or production of the good/service). This means that there is a divergence between private benefit and public benefit when a merit good is consumed (i.e. the public benefit is greater than the private benefit).
Externalities arise when consumption by individuals or production by firms affect the utility or production function of other individuals or firms. [22] Positive externalities are education, public health and others while examples of negative externalities are air pollution, noise pollution, non-vaccination and more. [23]
Externalities can be positive or negative depending on how a good/service is produced or what the good/service provides to the public. Positive externalities tend to be goods like vaccines, schools, or advancement of technology. They usually provide the public with a positive gain. Negative externalities would be like noise or air pollution.
In this way the provision of non-excludable goods is a classic example of a positive externality which leads to inefficiency. In extreme cases this can result in the good not being produced at all, or it being necessary for the government to organize its production and distribution.
For example, externalities of economic activity are non-monetary spillover effects upon non-participants. Odors from a rendering plant are negative spillover effects upon its neighbors; the beauty of a homeowner's flower garden is a positive spillover effect upon neighbors.
The engine for growth can be as simple as a constant return to scale production function (the AK model) or more complicated set ups with spillover effects (spillovers are positive externalities, benefits that are attributed to costs from other firms), increasing numbers of goods, increasing qualities, etc. [citation needed]
Nevertheless, governments also provide merit goods because of reasons of equity and fairness and because they have positive externalities for society as a whole. [15] In order to provide public and merit goods, the government has to buy input factors from private companies, e.g. police cars, school buildings, uniforms etc.
