Chapter 10/11 Flashcards
Negative externality
a situation when a person’s actions have a negative impact on a bystander
Positive externality
a situation when a person’s actions have a beneficial impact on a bystander
corrective tax
A tax designed to induce private desicion maker to take into account the social costs that arise from a negative externality
externality
the uncompensated impact of the actions of one person on a bystander
social cost
the sum of private and external costs
internalizing an externality
altering incentives so that people take into account the external effects of their actions
give an example of a negative externality and an example of a positive externality
The exhaust from automobiles is a negative externality because it creates smog that other people have to breathe. As a result of this externality, drivers tend to pollute too much. The federal government attempts to solve this problem by setting emission standards for cars. It also taxes gasoline to reduce the amount that people drive.
Restored historic buildings convey a positive externality because people who walk or ride by them can enjoy the beauty and the sense of history
that these buildings provide. Building owners do not get the full benefit of restoration and, therefore, tend to discard older buildings too quickly. Many local governments respond to this problem by regulating the destruction of historic buildings and by providing tax breaks to owners who restore them.
Coase theorem
the proposition that if private parties can bargain without cost over the allocation of resources, they can solve the problem of externalities on their own
transaction costs
the costs that parties incur in the process of agreeing and following through on a bargain
- In what way does the patent system help society
solve an externality problem?
The patent laws protect the rights of inventors by giving them exclusive use of their inventions
for a period of time. When a firm makes a technological breakthrough, it can patent the idea and capture much of the economic benefit for itself. The patent internalizes the externality by giving the firm a property right over its invention. If other firms want to use the new technology, they have to obtain permission from the inventing firm and pay it a royalty. Thus, the patent system gives firms a greater incentive to engage in research and other activities that advance technology.
- List some of the ways that the problems
caused by externalities can be solved without
government intervention.
- Moral codes and social sanctions
- Charities
- The interested parties to enter into a contract
- Relying on the self-interest of the relevant parties
- What are corrective taxes? Why do economists
prefer them to regulations as a way to protect
the environment from pollution?
Instead of regulating behavior in response to an externality, the government can use market-based policies to align private incentives with social efficiency. For instance, as we saw earlier, the government can internalize the externality by taxing activities that have negative externalities and subsidizing activities that have positive externalities. Taxes enacted to deal with the effects of negative externalities are called corrective taxes. They are also called Pigovian taxes after economist Arthur Pigou (1877–1959), an early advocate of their use. An ideal corrective tax would equal the external cost from an activity with negative externalities, and an ideal corrective subsidy would equal the external benefit from an activity with
positive externalities.
- Imagine that you are a nonsmoker sharing a
room with a smoker. According to the Coase
theorem, what determines whether your
roommate smokes in the room? Is this outcome
efficient? How do you and your roommate
reach this solution?
the Coase theorem after economist Ronald Coase, suggests that it can be very effective in some circumstances. According to the Coase theorem, if private parties can bargain over the allocation of resources at no cost, then the private market
will always solve the problem of externalities and allocate resources efficiently.
Explain what is meant by a good being
“excludable.” Explain what is meant by a good
being “rival in consumption.” Is a slice of pizza
excludable? Is it rival in consumption?
excludability: the property of a good whereby a person can be prevented from using it
rivalry in consumption: the property of a good whereby one person’s use diminishes other people’s use
A slice of pizza could be both
- Define and give an example of a public good.
Can the private market provide this good on its
own? Explain.
public goods: goods that are neither excludable nor rival in consumption - For example, a tornado siren in a small town is a public good A private market can’t provide is not excludable, people have an incentive to be free riders. A free rider is a person who receives the benefit of a good but does not pay for it. Because people would have an incentive to be free riders rather than ticket buyers, the market would fail to provide an efficient outcome.
- What is the cost-benefit analysis of public goods?
Why is it important? Why is it hard?
cost-benefit analysis: a study that compares the costs and benefits to society by providing a public good
They do not have any price signals to observe when evaluating whether the government should provide a public good and how much to provide. Their findings on the costs and benefits of public projects are rough approximations at best.
- Define and give an example of a common
resource. Without government intervention,
will people use this good too much or too little?
Why?
Common resources are rival in consumption but not excludable. For example, fish in the ocean are rival in consumption: When one person catches fish, there are fewer fish for the next person to catch. Yet these fish
are not an excludable good because, given the vast size of an ocean, it is difficult to stop fishermen from taking fish out of it.
People would use this good too much
Tragedy of the
Commons
a parable that illustrates why common resources are used more than is desirable from the the standpoint of society as a whole
private good
both excludable and rival in consumption
public good
neither excludable nor rival in consumption
common good
goods that are nonexcludable but rival in consumption
club good
excludable goods but nonrival in consumption
free rider
a person who receives
the benefit of a good but
avoids paying for it
3: Suppose that a commercial apple orchard uses pesticides in the production of apples. In the process, dangerous fumes drift across a nearby neighborhood. 1. Is this an example of a positive or a negative externality? Explain.
- If this externality is not internalized, does the market overproduce or underproduce apples? What does it mean to overproduce or underproduce a product?
- To internalize this externality, should the government tax or subsidize apples? Why or why not?
Short-Answer Questions Negative externality, because the social cost of producing apples exceeds the private cost of producing apples
Overproduce: To overproduce is to produce units Where the true cost exceeds the true value To underproduce t to fai, to produce unite where the true value exceeds the true cost.
Tax apples because to Internalize the externality, & requires that the supply curve for apples be Shifted upward until it equals the true social cost.
