A beekeeper lives adjacent to an apple orchard. The orchard owner benefits from the bees because each hive pollinates about one acre of apple trees. The orchard owner pays nothing for this service, however, because the bees come to the orchard without his having to do anything. Because there are not enough bees to pollinate the entire orchard, the orchard owner must complete the pollination by artificial means, at a cost of \(10 per acre of trees.

Beekeeping has a marginal cost MC = 10 + 5Q, whereQis the number of beehives. Each hive yields \)40 worth of honey.

a. How many beehives will the beekeeper maintain?

b. Is this the economically efficient number of hives?

c. What changes would lead to a more efficient operation?

Short Answer

Expert verified
  1. The beekeeper would be able to maintain 6 beehives.

  2. 6 beehives is not the efficient number of hives.

  3. The merger of both the business of a beekeeper and orchard will lead to a more efficient outcome.

Step by step solution

01

Explanation for part (a)

The revenue of the beekeeper will be maximized where marginal cost is equal to the marginal benefit.

The marginal benefit is $40 since that is the worth of honey produced by the hives, and the marginal cost is given, therefore:

40=10+5QQ=6

The beekeeper will maintain 6 beehives.

02

Explanation for part (b)

If there are too few bees to pollinate the orchard, the farmer, in that case, must pay $10 per acre for artificial pollination. Therefore, the farmer would pay up to $10 to the beekeeper to maintain each additional hive, which is the external cost. Thus,the marginal social benefit, $50, is greater than the marginal private benefit of $40.

Equating the marginal social benefit to marginal social cost:

50=10+5QQ=8

Therefore the economically efficient number would be 8.

03

Explanation for part (c)

If both the farmers merge their businesses, the farmer would be willing to pay $10 to the beekeeper. Therefore, this will always produce the most efficient outcome where the marginal social cost equals marginal social benefits.

In a market for dry cleaning, the inverse market demand function is given byP= 100 -Q, and the (private)marginal cost of production for the aggregation of all dry-cleaning firms is given by MC = 10 +Q. Finally, the pollution generated by the dry-cleaning process creates external damages given by the marginal external cost curve MEC =Q.

a. Calculate the output and price of dry cleaning if it is produced under competitive conditions without regulation.

b. Determine the socially efficient price and output of dry cleaning.

c. Determine the tax that would result in a competitive market producing the socially efficient output.

d. Calculate the output and price of dry cleaning if itis produced under monopolistic conditions without regulation.

e. Determine the tax that would result in a monopolistic market producing the socially efficient output.

f. Assuming that no attempt is made to monitor or regulate the pollution, which market structure yields higher social welfare? Discuss.

Medical research has shown the negative health effects of โ€œsecondhandโ€ smoke. Recent social trends point to growing intolerance of smoking in public areas. If you're a smoker and you wish to continue smoking despite tougher anti-smoking laws, describe the effect of the following legislative proposals on your behaviour. As a result of these programs, do you, the individual smoker, benefit? Does society benefit as a whole?

a. A bill is proposed that would lower tar and nicotine levels in all cigarettes.

b. A tax is levied on each pack of cigarettes.

c. A tax is levied on each pack of cigarettes sold.

d. Smokers would be required to carry government-issued smoking permits at all times.

A computer programmer lobbies against copyrighting software, arguing that everyone should benefit from innovative programs written for personal computers and that exposure to a wide variety of computer programs will inspire young programmers to create even more innovative programs. Considering the marginal social benefits possibly gained by this proposal, do you agree with this position?

There are three groups in a community. Their demand curves for public television in hours of programming, T, are given respectively by

W1 = \(200 -T

W2 = \)240 - 2T

W3 = \(320 - 2T

Suppose public television is a pure public good that can be produced at a constant marginal cost of \)200per hour.

a. What is the efficient number of hours of public television?

b. How much public television would a competitive private market provide?

A number of firms have located in the western portion of a town after single-family residences took up the eastern portion. Each firm produces the same product and, in the process, emits noxious fumes that adversely affect the residents of the community.

a. Why is there an externality created by the firms?

b. Do you think that private bargaining can resolve the problem? Explain.

c. How might the community determine the efficient level of air quality?
