Exam 10: Externalities

When externalities are present in a market,how is the well-being of market participants and market bystanders affected by government policies

Since externalities tend to keep markets from reaching a socially optimal equilibrium,when is government action needed

In a market characterized by externalities,the market equilibrium fails to maximize the total benefit to society as a whole.

Because decisions in a market economy are guided by individual self-interest,what exists in an economy

What is government intervention that aims to promote technology-enhancing industries called

In essence,the corrective tax places a price on the right to pollute.

The Credit River has two polluting firms on its banks. Plants A and B each dump 100 tonnes of effluent into the river each year. The cost per tonne of reducing emissions is $20 for plant A and $100 for Plant B. The government wants to reduce overall pollution from 200 tonnes to 50 tonnes. a.If the government knew the cost of reduction for each firm, what reductions would it impose in order to achieve its overall goal at the least possible total cost? What would be the cost to each firm, and the total cost? b.If, in the absence of information about each firm’s costs, the government decided to reach its overall goal by imposing uniform reductions on the firms, what would be the cost to each firm, and the total cost? c.Compare the total costs in parts a and b. If the government does not know the cost of pollution reduction for each firm, is there still some way to reduce pollution to 50 tonnes at the total cost calculated in part a?

What results once tradable pollution permits have been allocated to firms

What will arise when negative externalities are present in a market

When a beekeeper places his hives of bees in an orchard so that the bees can gather nectar to produce honey,the bees pollinate the orchard,which increases the yield of fruit.What is the economic explanation of this activity

Negative externalities lead markets to produce a smaller quantity of a good than is socially desirable,while positive externalities lead markets to produce a larger quantity of a good than is socially desirable.

What is one advantage of allowing a market for pollution permits to control the total amount of pollution released in an area

Which example illustrates the concept of a negative externality?

Figure 10-2 -Refer to Figure 10-2.At Q₃,how does a consumer value the cost of the product

Two firms,A and B,each currently dump 50 tonnes of chemicals into the local river.From now on both firms will require a pollution permit for each tonne of pollution dumped.It costs Firm A $100 for each tonne of pollution that it eliminates before it reaches the river,and it costs Firm B $50 for each tonne of pollution that it eliminates before it reaches the river.The government gives each firm 20 pollution permits.What is the total cost of reducing pollution if the firms are NOT allowed to buy and sell pollution permits from each other,and,NOT including the cost of buying

The Coase theorem suggests that efficient solutions to externalities can be arrived at through bargaining. Under what circumstances does this fail to produce a solution?

When a negative externality exists in a market,how does the cost to producers compare with the cost to society

If an externality is present in a market,what may enhance economic efficiency

When does an externality exist
