Examples of positive consumption externalities include: An individual who maintains an attractive house may confer benefits to neighbors in the form of increased market values for their properties. This is an example of a pecuniary externality, because the positive spillover is accounted for in market prices.
Coase used the example of pollution (raised by George Stigler in The Theory of Price, 1952) several times: he argued that arbitrage between actors in a market with low transaction costs could lead to an efficient market solution. [6] Coase extends this framework throughout his development of a functional theorem concerning externalities.
Ultimately, because non-pecuniary externalities overestimate the social value, they are over-produced. To deal with over-production, Pigou recommends a tax placed on the offending producer. If the government can accurately gauge the social cost, the tax could equalize the marginal private cost and the marginal social cost.
Mathematically, social marginal cost is the sum of private marginal cost and the external costs. [3] For example, when selling a glass of lemonade at a lemonade stand, the private costs involved in this transaction are the costs of the lemons and the sugar and the water that are ingredients to the lemonade, the opportunity cost of the labor to combine them into lemonade, as well as any ...
Environmental economics is related to ecological economics but there are differences. Most environmental economists have been trained as economists. They apply the tools of economics to address environmental problems, many of which are related to so-called market failures—circumstances wherein the "invisible hand" of economics is unreliable ...
The impact of social norms on the free-rider problem differs between cultural contexts, which may lead to a variance between results in research on the free-rider problem when applied cross-culturally. Social norms impact on privately and voluntarily provided public goods; however, is considered to have some level of effect on the problem in ...
Different economists have different views about what events are the sources of market failure. Mainstream economic analysis widely accepts that a market failure (relative to Pareto efficiency) can occur for three main reasons: if the market is "monopolised" or a small group of businesses hold significant market power, if production of the good or service results in an externality (external ...
Positive externalities are education, public health and others while examples of negative externalities are air pollution, noise pollution, non-vaccination and more. [ 23 ] Pigou describes as positive externalities , examples such as resources invested in private parks that improve the surrounding air, and scientific research from which ...
