Externalities, Property Rights, and the Coase Theorem

Quick Quiz

The following nine questions relate to the graph below and the story that follows. Mr. Loud Mouth buys tickets to a baseball game. He is more interested in beer and raucous behaviour than in baseball, and so he makes life difficult for Mr. Ardent Fan, who is seated next to him. The marginal benefit curve on the graph shows the extra benefit Loud gets from each successive beer. Thus the area under the curve is the total perceived benefit he gets from beer. If he tried to protect people like Ardent from being annoyed, he would have to stop drinking or hire someone to monitor his behaviour and keep it in check. The more he drinks, the more expensive the monitor. This cost is listed as "Cost of monitoring beer drinker". Two other costs are relevant to this problem. First, Ardent Fan could absorb the irritation by staying in the next seat. This cost function is called "Cost of sitting next to beer drinker". Finally, Mr. Fan could move back to a less desirable, but unoccupied seat. This function is called "Cost of moving away". The more beer Loud drinks the farther Ardent must move away. If the rules allow Loud Mouth to do as he pleases and Mr. Mouth and Mr. Fan can negotiate without cost, how many drinks will Loud consume?

B)There is no efficient outcome of an externality problem.
C)If negotiation costs are zero, it makes no difference who is responsible because efficiency will be reached.
D)If negotiation costs are zero, efficiency is best served if the person held responsible for the problem is the one with the highest cost of solving the problem.

7

The moral of the story in questions 17-4 to 17-6 is that
A)when negotiation costs are prohibitive, the best alternative is to make the person responsible who has the highest cost of solving the problem.
B)when negotiation costs are prohibitive, the best alternative is to make the person responsible who has the lowest cost of solving the problem.
C)a law outlawing beer at games would serve society best.
D)no rules or regulations are necessary. Let the parties battle to some solution or live in conflict. The medicine of rules is worse than the externality disease.
8
