Externalities [WLO: 4] [CLOs: 1, 2, 4, 6, 7]
ANSWER
Differences between Positive Externality and Negative Externality:
Positive externality and negative externality are two distinct concepts in economics that refer to the external effects of economic activities. Here are the key differences between the two:
- Nature of Impact:
- Positive Externality: A positive externality occurs when an economic activity generates benefits for parties other than the immediate participants. These benefits are not directly considered in the market transaction and, as a result, are underrepresented. Positive externalities lead to a situation where social benefits exceed private benefits.
- Negative Externality: On the other hand, a negative externality arises when an economic activity imposes costs on parties not directly involved in the activity. These costs are not accounted for in the market transaction, causing social costs to exceed private costs.
- Market Outcome:
- Positive Externality: In the presence of a positive externality, the market tends to underproduce the good or service since the additional benefits to society are not being fully considered by individual buyers and sellers.
- Negative Externality: With a negative externality, the market often overproduces the good or service because the negative costs affecting society are not fully taken into account by buyers and sellers.
Example of Positive Externality: Education Education is a classic example of a positive externality. When individuals receive education, they not only benefit themselves by gaining knowledge and skills but also contribute to the overall productivity and advancement of society. A highly educated population tends to lead to lower crime rates, better health outcomes, technological innovation, and a more informed citizenry. However, individuals pursuing education primarily consider their personal gains, leading to an underinvestment in education from a societal perspective.
Example of Negative Externality: Pollution Pollution is a prominent example of a negative externality. Consider a factory that produces goods but releases pollutants into the air and water as byproducts. The costs associated with these pollutants, such as health issues and environmental degradation, are borne by the general public rather than the factory owner alone. As a result, the market price of the goods does not reflect the true social cost of production.
Solving Externalities and Government Intervention:
To attain market efficiency and address externalities, interventions are often necessary:
- Positive Externality Solution: In the case of positive externalities like education, the government can subsidize education by providing grants, scholarships, or funding for educational institutions. This reduces the gap between private and social benefits, encouraging more individuals to pursue education.
- Negative Externality Solution: For negative externalities like pollution, the government can impose taxes or regulations on polluters. For example, implementing a carbon tax on industries emitting greenhouse gases would make the cost of pollution a part of the production cost, encouraging them to adopt cleaner technologies.
Government Intervention: Government intervention is often required to correct externalities, especially when the market alone fails to account for the external costs or benefits. By internalizing these externalities, interventions aim to align private actions with social welfare, thus promoting market efficiency.
In conclusion, positive and negative externalities highlight the impacts of economic activities on parties not directly involved in transactions. Addressing these externalities is crucial for achieving optimal market outcomes and maximizing overall societal welfare. While government intervention may be needed to correct externalities, it should be carefully designed to balance the costs and benefits of such interventions.
QUESTION
Description
Externalities are costs or benefits associated with consumption or production that are not incurred by the consumer or producer and are therefore not reflected in market prices. The cost or benefit of an externality remains external when falling to parties other than the buyer or seller.
Respond to the following:
Describe some differences between a positive externality and a negative externality.
Provide one example of a positive externality and a negative externality, respectively. Explain your reasoning.

- Does the government need to intervene with externalities to effect market efficiency?
- Your initial post should be a minimum of 300 words.
