A negative externality (also called "external cost" or "external diseconomy") is an economic activity that imposes a negative effect on an unrelated third party, not captured by the market price. It can arise either during the production or the consumption of a good or service.
The tax is normally set by the government to correct an undesirable or inefficient market outcome (a market failure) and does so by being set equal to the external marginal cost of the negative externalities. In the presence of negative externalities, social cost includes private cost and external cost caused by negative externalities.
In law and economics, the Coase theorem (/ ˈ k oʊ s /) describes the economic efficiency of an economic allocation or outcome in the presence of externalities.The theorem is significant because, if true, the conclusion is that it is possible for private individuals to make choices that can solve the problem of market externalities.
A pecuniary externality occurs when the actions of an economic agent cause an increase or decrease in market prices. For example, an influx of city-dwellers buying second homes in a rural area can drive up house prices, making it difficult for young people in the area to buy a house.
A merit good can be defined as a good which would be under-consumed (and under-produced) by a free market economy, due to two main reasons: 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 ...
In economics, the principle of absolute advantage is the ability of a party (an individual, or firm, or country) to produce a good or service more efficiently than its competitors. [1] [2] The Scottish economist Adam Smith first described the principle of absolute advantage in the context of international trade in 1776, using labor as the only ...
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 ...
However, if the road is congested, one more person driving the car makes the road more crowded which causes slower passage. In other words, it creates a negative externality and road becomes common good. [1] Clean water and air - Climate stability belongs to classic modern examples. [2] Water and air pollution is caused by market negative ...
