Externalities can lead to market failures from "summary" of Basic Economics by Thomas Sowell
Externalities occur when the actions of individuals or firms have an impact on third parties who are not directly involved in the market transaction. These external effects can be positive or negative, and they are not reflected in the prices that buyers pay or sellers receive. As a result, market participants do not take these external costs or benefits into account when making their decisions. When externalities exist, market outcomes are not efficient because the prices that guide decision-making do not fully capture all the costs and benefits of production and consumption. This leads to a divergence between private costs and social costs, or between private benefits and social benefits. In the presence of negative externalities, such as pollution, the market will produce more of the good than is socially optimal because the cost of pollution is not borne by the producers or consumers. On the other hand, positive externalities, such as education, may result in underproduction because the full benefits are not captured by the producers or consumers. Market failures occur when the allocation of resources by the market is not efficient, leading to a loss of economic welfare. Externalities are one of the main reasons for market failures because they cause a divergence between private and social costs and benefits. In the case of negative externalities, the market overproduces the good, leading to a misallocation of resources. In the case of positive externalities, the market underproduces the good, resulting in a suboptimal allocation of resources. Policymakers can intervene to correct these market failures by internalizing the externalities, either through taxes or subsidies. By imposing taxes on producers who create negative externalities or providing subsidies to those who generate positive externalities, policymakers can align private costs and benefits with social costs and benefits. This internalization of externalities helps to ensure that resources are allocated efficiently and that economic welfare is maximized.
