Chapter 16- Externalities
What is another name for tradable emissions permits?
Cap and trade systems
According to this, the private sector can correct externalities and produce the efficient level of the good, provided that transaction costs are sufficiently low
Coase Theorem
This states that externalities need not lead to inefficiencies, since people have an incentive to make mutually beneficial transactions, which leads individuals to take externalities into account when making decisions, provided that transaction costs are not too great
Coase Theorem
Taxes that depend on the amount of pollution a firm produces
Emissions Taxes
Rules that protect the environment, by specifying what actions need to be taken by producers and consumers
Environmental Standards
An uncompensated benefit that an individual or firm confers on others; also known as positive externality
External Benefit
External Benefits and external costs
Externalities
True or False: It is likely that the market will generate the optimal amount of pollution
False (those who produce the pollution do not have to bear the costs of pollution)
When transaction costs prevent people from internalizing the externality, what must happen to correct the market and its failure to internalize the externality?
Government Intervention
This does not occur if the cost of communication between the affected parties is too high, if the cost of making a legally binding contract is too great, or if there are costly delays in the bargaining.
Internalization of an externality
Further reduction in pollution emissions will continue to increase total surplus until that level of pollution emissions is achieved where ____=____
MSC, MSB
The additional benefit to society from an additional unit of pollution
Marginal Social Benefit of pollution
The additional cost imposed on society of an additional unit of pollution
Marginal social cost of pollution
This occurs when the value of a good to a consumer increases as more people own or use the good; frequently occur in technology driven sectors of the economy
Network Externality
Do the companies and individuals who create pollution typically bear the cost of their negative externality?
No (borne by the entire society)
A payment designed to encourage activities that yield external benefits
Pigouvian Subsidy
To gain the socially optimum amount of a positive externality requires what?
Pigouvian Subsidy
The use of taxes to address the problem of negative externality, used to reduce external costs
Pigouvian Tax
Taxes that are designed to reduce external costs
Pigouvian Taxes
The quantity of pollution that society would choose if all the costs and benefits of pollution were fully accounted for
Socially Optimal Quantity of Pollution
_____ can be used to reduce any kind of activity that generates a negative externality
Taxes
A term that describes the spread of knowledge among individuals and firms: it measures the external benefit that occurs when new knowledge is discovered in one application and then this knowledge is used in other applications
Technology Spillover
One of the problems with pollution is that it inflicts a cost on who?
The entire society
licenses granted by the government that give the holder of the license permission to emit limited quantities of the pollutant; can be bought and sold by the polluter
Tradable Emissions Permits
The costs to individuals of making a deal
Transaction Costs
True or False: Although effective as a policy, Pigouvian taxes are difficult to implement since government officials do not always know with certainty what level of tax is the efficient level of tax
True
True or False: An emissions tax is more efficient than an environmental standard, since the emissions tax ensures that the marginal benefit of pollution is equal for all sources of pollution, while environmental standard does not consider the marginal benefit of pollution when it is enforced
True
True or False: When externalities are present, the market fails to produce the optimal amount of the good
True
True or False: Environmental standards are inefficient
True (inflexible, and do not incorporate the costs of reducing pollution)
What is the optimum level of pollution for a society?
When marginal social cost (of pollution)= marginal social benefit (of pollution)
In the absence of government intervention, polluters will pollute up to the point where Marginal Social Benefit is equal to what?
Zero
When an externality cannot be directly observed, then the government must implement policies that do what?
aim at generating the right amount of the activity that produces the externality
From a producers prospective, the benefit from emitting one more unit of pollution is measured by the costs the producer saves from not having to do what?
buy and install expensive pollution-control equipment
Pollution generates what two things for society?
costs and benefits
When the level of pollution is limited by tradable emissions permits, this results in producers basing their decision about whether or not to pollute on the basis of what?
costs of reducing their pollution
A reduction in pollution emissions will result in a large _____ in the total social cost of pollution emissions, while causing ____ change in the total social benefits of pollution emissions
decrease, little
What is the government's greatest challenge when implementing tradable emissions permits?
determining the optimal number of permits for the economy
When an externality can be directly observed, then it can be regulated through what?
direct controls, taxation, subsidization
The Marginal social benefit of pollution is a (n) ________ sloping line; when pollution is negligible, an additional unit has a high benefit to society; when there is a lot of pollution, an additional unit brings little benefit to society
downward
Both _______ and _______ create an incentive for producers to create and use less-polluting technology
emissions taxes, tradable emissions permits
The government can reduce the amount of pollution by doing what?
enforcing environmental standards
When an activity generates an external benefit, or a benefit received by someone other than the people directly involved in the transaction, the market does not produce ______ of this good
enough
An uncompensated cost that an individual or firm imposes on others; also known as a negative externality
external cost
When the government implements an optimal Pigouvian tax, it shifts the supply curve up by the _________
external cost
A principal source of market failure occurs when the market fails to take into account side effects or _______ of consumption or production decisions
externalities
Cap and Trade systems are efficient with pollution that is dispersed, but is less effective with pollution that is ________ localized
geographically
The market level of pollution is ______ than the optimal level of pollution, and that market level of pollution is ______ since, at this level of pollution, the marginal social cost of pollution is ______ than the marginal social benefit of pollution
greater, inefficient, greater
One can measure the marginal social benefit of an additional unit of pollution by finding out what is the ___________ to pay for the right to emit this unit of pollution among all the polluters in the society
highest willingness
A reduction in pollution emissions, does what to total surplus?
increases it
When individuals take into account externalities when making decisions

In the case of a positive externality, the market produces too ____ of the good if it does not take into account the externality
little
Companies recognize the importance of network externalities and the positive feedback effect, and they sometimes offer a new product at a very ____ price in hopes of generating a strong network effect

With network externality, the _________ to the individual is dependent on the number of other individuals who use the good
marginal benefit
In the case of a negative externality, the market produces too ____ of the good if it does not take into account the externality
much
A ______ externality is a side effect that imposes costs to others
negative
In the case of a positive externality, the government must target what, rather than the external benefit, because the external benefit can be difficult or impossible to measure
original activity
A ________ externality is a side effect that provides benefits to to others

A good with a network externality exhibits __________: as more people use the good, even more people are inclined to use the good and if fewer people use the good, then fewer people are inclined to use the good
