How do externalities affect the economy?

• A. They always result in a negative impact
• B. They create market monopolies
• C. They influence the supply and demand balance
• D. They only affect specific markets

Answer: (C)

Externalities significantly influence the supply and demand balance in an economy by introducing costs or benefits that are not reflected in market prices. When externalities are present, the actions of individuals or businesses can have repercussions on third parties, which are not included in the economic transactions taking place. For instance, when a factory emits pollution, the surrounding community suffers health issues or environmental damage that the factory does not have to pay for. This type of negative externality means that the true cost of producing goods is higher than the market price reflects, leading to overproduction of harmful goods. Conversely, positive externalities, such as the benefits of a well-educated workforce derived from public education, can result in underproduction because those benefits are not captured by the market, leading to insufficient investment in education. As a result, externalities disrupt the efficient allocation of resources. They create a divergence between private costs or benefits and social costs or benefits, causing the supply or demand curves to shift, which can lead to inefficiencies in the market. Understanding how externalities impact supply and demand is crucial for addressing market failures and ensuring that economic resources are utilized effectively.
