Externalities 2683
43. Suppose that Company A’s railroad cars pass through Farmer B’s corn fields. The railroad causes
an externality to the farmer because the railroad cars emit sparks that cause $1,500 in damage to
the farmer’s crops. There is a special soy-based grease that the railroad could purchase that
would eliminate the damaging sparks. The grease costs $1,200. Suppose that the railroad is not
liable for any damage caused to the crops. Assume that there are no transaction costs. Which of
the following characterizes the efficient outcome?
a. The railroad will continue to operate but will pay the farmer $1,500 in damages.
b. The railroad will purchase the grease for $1,200 and pay the farmer nothing because no crop
damage will occur.
c. The farmer will incur $1,500 in damages to his crops.
d. The farmer will pay the railroad $1,200 to purchase the grease so that no crop damage will
occur.
44. Suppose that Charles wants to dine at a fancy restaurant, but the only available table is
in the smoking section. Charles dislikes the smell of cigarette smoke. He notices that only one
person, Sam, is smoking in the smoking section. Charles values the absence of smoke at $40.
Sam values the ability to smoke in the restaurant at $15. Which of the following represents an
efficient solution in the absence of transaction costs?
a. Sam continues to smoke because he has a right to smoke in the smoking section.
b. Charles offers Sam between $15 and $40 not to smoke. Sam accepts, and both parties are
better off.
c. Charles offers Sam between $15 and $40 not to smoke. Sam declines because he has a right to
smoke in the smoking section.
d. Only a government policy banning smoking in restaurants will solve this problem.
