D) marginal external cost of producing a ton of cement is $7,500.
E) marginal external cost of producing a ton of cement is $4,000.
43) If a good has an external cost, then the marginal private cost curve
A) lies below then the marginal social cost curve.
B) lies above the marginal social cost curve.
C) lies below the horizontal axis.
D) is the same as the marginal external cost curve.
E) is undefined because the firms’ costs are not equal to the social costs.
44) The marginal external cost and marginal private cost
A) are all borne by the seller.
B) are opportunity costs.
C) when added, equal the sum of the marginal private benefit plus the marginal social benefit at equilibrium.
D) are regulated by the government.
E) must always be equal in equilibrium.
45) If the production of a good causes an external cost, then the efficient quantity is
A) equal to the quantity at which the marginal benefit equals marginal cost.
B) less than the quantity at which the marginal benefit equals the marginal cost.
C) more than the quantity at which the marginal benefit equals the marginal cost.
D) the quantity at which the marginal private benefit is greater than the marginal social benefit.
E) None of the above answers is correct.
46) If a good has an external cost, the
A) unregulated competitive market outcome is efficient.
B) marginal private cost reflects the external cost.
C) unregulated competitive market outcome is inefficient.
D) marginal social benefit is equal to the marginal social cost when the market is in equilibrium.
E) external benefit must equal the external cost.
47) The basic reason that a competitive unregulated market produces an inefficient amount of a good with an external cost because
A) producers cannot measure marginal social cost.
B) producers do not pay the external cost.
C) the general public does not care about external costs.
D) external costs are not a political issue.
E) the external cost is paid by consumers rather than producers.
48) When production of a good results in an external cost, the unregulated competitive market equilibrium quantity is
A) the efficient level of output.
B) greater than the efficient level of output.
C) not zero but is less than the efficient level of output.
D) unattainable.
E) zero.
49) If producing a good or a service creates pollution, then
A) an unregulated competitive market produces an efficient output.
B) the industry’s supply curve includes the extra cost of pollution.
C) at the unregulated, competitive market equilibrium quantity, marginal social cost is greater than the equilibrium price.
D) at the unregulated, competitive market equilibrium quantity, marginal social benefit and marginal social cost are equal.
E) at the unregulated, competitive market equilibrium quantity, marginal social benefit is less than the equilibrium price.
50) An external cost in the production of a good creates a difference between the
