Which statement best explains why problems related to negative externalities are difficult to solve?

• A. There are not tangible issues
• B. Externalities do not matter
• C. There is no perfect solution
• D. Trade-offs exist

Answer: (D)

Dealing with negative externalities requires balancing different costs and benefits across society. When a production activity imposes costs on others, the market outcome isn’t socially optimal, so policy aims to correct that gap. But any policy—taxes, fines, regulations, or permits—imposes costs on some groups and benefits on others, and it can create unintended side effects or shift problems rather than eliminate them. Because you must weigh efficiency gains against equity concerns, enforcement costs, and informational limits, there isn’t a single perfect fix. That’s why the idea that trade-offs exist best explains why these problems are difficult to solve. Other statements miss this essential balancing act or overstate simplicity.
