A city builds a new lighthouse on its coast. The light from the lighthouse helps all ships in the area navigate safely, regardless of how many ships are present. The city funded the construction through taxes, and it is impossible to charge individual ships for using the light as they pass. Which aspect of this situation best demonstrates the defining characteristic of a public good?

A key characteristic used to classify economic goods is 'rivalry'—the extent to which one person's use of a good diminishes its availability for others. A good is considered 'non-rival' if one person's consumption does not reduce the amount available for someone else. Which of the following scenarios describes a good that is best characterized as non-rival?

Community Project Funding Dilemma

A good can be classified based on two key characteristics: whether its consumption by one person prevents another from consuming it (rivalry), and whether it is possible to prevent people who have not paid for it from having access to it (excludability). Match each type of good with its correct description based on these characteristics.

A group of residents in a neighborhood proposes hiring a private security firm to patrol their streets at night.

Evaluating a Policy for Improving Air Quality

A company develops a new, highly effective mosquito repellent formula and sprays it over a large public park. The spray eliminates all mosquitoes in the area for a week, and anyone visiting the park benefits from the mosquito-free environment. The company cannot charge individual park visitors for this benefit. However, the pleasant, mosquito-free air in the park does not extend to the surrounding neighborhoods. Which statement best analyzes this situation in the context of a public good?

A national radio station incurs a total cost of $50,000 to produce and transmit a specific one-hour program. Once the program is broadcast, its signal is available to anyone with a radio receiver in the broadcast area. From an economic perspective, what is the cost of allowing one more person within this area to listen to the program?

Analyze the characteristics of each item listed below and match it to the correct economic classification based on its properties of rivalry (whether one person's use prevents another's) and excludability (whether people can be prevented from using it).
