Question 45

Negative externalities in a market result in overproduction.

When negative externalities are present in a market, they typically lead to overproduction of goods or services, as the costs of these externalities are not reflected in the market price, resulting in an inefficient allocation of resources.

A) Efficiencies

This option is incorrect because negative externalities do not lead to efficiencies. Instead, they create market failures where the social costs exceed private costs, resulting in an inefficient outcome rather than an efficient one.

B) Overproduction

This option is correct as negative externalities cause overproduction. Producers do not take into account the external costs imposed on society, leading them to produce more than the socially optimal level, thus creating a surplus that harms overall welfare.

C) Subsidies

This option is incorrect because subsidies are financial aids provided to encourage production or consumption of certain goods, which does not directly relate to the concept of negative externalities causing overproduction. In fact, subsidies could exacerbate the problem by encouraging even more production without addressing the external costs.

D) Underproduction

This option is incorrect because underproduction occurs when the market fails to produce enough of a good or service to meet social demand. Negative externalities lead to overproduction, as the costs associated with the negative impacts are not accounted for by the producers.

Conclusion

In summary, the presence of negative externalities in a market leads to overproduction, as producers ignore the external costs their activities impose on society. Options A, C, and D fail to recognize this fundamental issue, while option B accurately captures the inefficiency created by negative externalities. Understanding this concept is crucial for addressing market failures and achieving a more efficient allocation of resources.
