Exam 10: Externalities

Figure 10-2 -Refer to Figure 10-2.If this market currently produces Q₂,how could total economic well-being be maximized

What is the effect of a negative externality

Why would corrective taxes NOT be preferred over regulations in order to reduce pollution

How can the government internalize a positive externality

Imagine you are a nonsmoker sharing a house with a smoker. According to the Coase theorem, what determines whether your roommate smokes in the house? Is this outcome efficient? How do you and your roommate reach this solution?

When a transaction between a buyer and seller directly affects a third party,the effect is called an externality.

Using a supply and demand diagram, demonstrate how a positive externality leads to market inefficiency. How might the government help to eliminate this inefficiency?

Assume that your roommate,Vanessa,is very messy,and according to campus policy,you have a right to live in an uncluttered apartment.Suppose she gets a $200 benefit from being messy but imposes a $100 cost on you.What would the Coase theorem suggest would be an efficient solution for your roommate

What does the height of the supply curve show

A market for pollution permits can efficiently allocate the right to pollute by the forces of supply and demand.

What does the demand curve for a product reflect

Social welfare can be enhanced by allowing firms to trade their rights to pollute.

What are two types of private solutions to the problem of externalities

Figure 10-3 -Refer to Figure 10-3.How is the negative externality measured

Figure 10-1 This figure reflects the market for outdoor concerts in a public park surrounded by residential neighbourhoods. -Refer to Figure 10-1.What price and quantity combination best represents the optimum price and number of concerts that should be organized

What does the height of the supply curve at any given quantity of coal show

If the government wanted to ensure that the market reaches the social optimum in the presence of a technology spillover,what should it do

The social cost of pollution includes the private costs of the producers plus the costs to those bystanders affected adversely by the pollution.

Using a supply and demand diagram,demonstrate how a negative externality leads to market inefficiency.How might the government help to eliminate this inefficiency

Two firms,A and B,each currently dump 20 tonnes of chemicals into the local river.From now on both firms will require a pollution permit for each tonne of pollution dumped into the river.The government gives each firm 10 pollution permits,which it can either use or sell to the other firm.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.After the two firms buy or sell pollution permits from each other,what would we expect
