Radio stations, tornado sirens, light houses, and street lights are all public goods in that all are nonrivalrous and nonexclusionary. Therefore why does the government provide tornado sirens, street lights and light houses but not radio stations (other than PBS stations)?

Short Answer

Expert verified
The government provides tornado sirens, street lights, and lighthouses because they are nonrivalrous, nonexclusionary public goods that contribute significantly to public safety and welfare. On the other hand, radio stations, which also share nonrivalry and nonexclusion characteristics, are not essential for public safety and can generate revenue through advertisements and subscriptions. This allows private entities to operate radio stations, while the government funds public broadcasting services (PBS) due to their focus on socially valuable educational, cultural and public affairs programming.

Step by step solution

01

Understand public goods

A public good is a good that is nonrivalrous and nonexclusionary. Nonrivalrous means that one person's consumption of the good does not reduce the availability of the good to others, while nonexclusionary means that it is very difficult (or even impossible) to prevent someone from consuming the good. Examples of public goods include national defense, clean air, and street lights.
02

Examine the role of government in providing public goods

The government plays a crucial role in providing public goods because, in many cases, the free market would not provide them adequately. This is mainly due to the free-rider problem, where individuals can benefit from the good without contributing to its cost, resulting in a lack of incentive to pay for it. The government steps in to ensure the provision of such goods through taxes or other funding sources.
03

Analyze the reasons for the government providing tornado sirens, street lights, and lighthouses

Tornado sirens, street lights, and lighthouses are considered public goods because they are nonrivalrous and nonexclusionary. These goods strongly contribute to public safety and welfare. Tornado sirens serve as an early warning system for communities, alerting residents of an approaching tornado, which can save lives and reduce damage. Street lights ensure safety on roads and streets, deterring crime and reducing accidents. Lighthouses are essential for safe navigation, helping to prevent maritime accidents, and protect the marine environment. In all these cases, the free-rider problem could lead to insufficient provision, so the government steps in to ensure these public goods are adequately available for everyone's benefit.
04

Discuss why the government does not provide radio stations (excluding PBS stations)

While radio stations also share characteristics of nonrivalry and nonexclusion, they are not considered essential for preserving life, property, and public safety in the same way as tornado sirens, street lights, and lighthouses. Furthermore, radio stations can generate revenue through advertisements and subscriptions, providing sufficient incentives for private entities to operate them. However, public broadcasting services (PBS) are partially funded by the government because their focus is on educational, cultural and public affairs programming, which are considered to be socially valuable, yet may not be as profitable for private companies. By understanding the characteristics of public goods and the role of government in providing them, we can see why the government steps in to provide tornado sirens, street lights, and lighthouses, whereas radio stations, except for PBS stations, are left to the private entities in the market.

Explain why the federal government funds national defense.

Assume that the marginal private costs of a firm producing fuel-efficient cars is greater than the marginal social costs. Assume that the marginal private benefits of a firm producing fuel-efficient cars is the same as the marginal social benefits. Discuss one way that the government can try to increase production and sales of fuel efficient cars to the socially desirable amount. Hint: the government is trying to affect production through costs, not benefits.

Provide two examples of goods/services that are classified as private goods/services even though they are provided by a federal government.

HighFlyer Airlines wants to build new airplanes with greatly increased cabin space. This will allow HighFlyer Airlines to give passengers more comfort and sell more tickets at a higher price. However, redesigning the cabin means rethinking many other elements of the airplane as well, like engine and luggage placement, and the most efficient shape of the plane for moving through the air. HighFlyer Airlines has developed a list of possible methods to increase cabin space, along with estimates of how these approaches would affect the plane's operating costs and ticket sales. Based on these estimates, Table 13.5 shows the value of \(\mathrm{R} \& \mathrm{D}\) projects that provide at least a certain private rate of return. Column 1 = Private Rate of Return. Column 2 = Value of R\&D Projects that Return at Least the Private Rate of Return to HighFlyer Airlines. Use the data to answer the following questions. $$\begin{array}{c|c}\hline \text { Private Rate of Return } & \text { Value of R\&D } \\\\\hline 12 \% & \$ 100 \\ \hline 10 \% & \$ 200 \\\\\hline 8 \% & \$ 300 \\\\\hline 6 \% & \$ 400 \\\\\hline 4 \% & \$ 500 \\\\\hline\end{array}$$ a. If the opportunity cost of financial capital for HighFlyer Airlines is \(6 \%,\) how much should the firm invest in R\&D? b. Assume that the social rate of return for \(\mathrm{R} \& \mathrm{D}\) is an additional \(2 \%\) on top of the private return; that is, an \(\mathrm{R} \& \mathrm{D}\) investment that had a \(7 \%\) private return to HighFlyer Airlines would have a \(9 \%\) social return. How much investment is socially optimal at the \(6 \%\) interest rate?
