2. After a hurricane, Florida hoteliers often find that people cancel their upcoming vacations, leaving them with empty hotel rooms. This causes:

Marginal social benefit equals marginal social cost.
Marginal social benefit is greater than marginal social cost.

6. Public goods are distinguished by two primary characteristics

9. Rocky Mountain Forest is a government-owned forest in which private citizens were allowed in the past to harvest as much timber as they wanted free of charge. Which of the following statements best describes the problem with this scenario?
Since the Rocky Mountain Forest is government owned, it is likely to be inefficient.
Since the timber is free, the individual’s marginal cost of harvesting the timber is greater than the marginal social cost of harvesting a tree, leading to over harvesting.
The marginal social cost of harvesting a tree is greater than a private logger’s individual marginal cost, which leads to over harvesting.
