試題 :
1.The table below shows the possible output levels of a firm whose production
has positive externalities to its neighborhood; together with the values of
firm's net private benefits to its neiborhood under various output levels.
╭────┬──────────┬───────────╮
│quantity│net private benefit │neighborhood's benefit│
├────┼──────────┼───────────┤
│ 0 │ $0 │ $0 │
├────┼──────────┼───────────┤
│ 1 │ $20 │ $10 │
├────┼──────────┼───────────┤
│ 2 │ $40 │ $20 │
├────┼──────────┼───────────┤
│ 3 │ $33 │ $30 │
├────┼──────────┼───────────┤
│ 4 │ $30 │ $31 │
└────┴──────────┴───────────┘
(1)What is the production level that maximizes social benefit?(5%)
(2)If the firm has the right to determine its quantity, what will be the
quantity produced? What if the neighborhood has the right? Is either
quantity the social optimum?(5%)
(3)If negotiation between the firm and the neighborhood is not possible, what
can the government do to attain social optimum?(10%)
(4)If negotiation is perfect(frictionless) between the two parties, what will
happen even without intervention? How do your results confirm the two main
predictions of the Coase Theorem?(15%)
(5)Suppose the cost of negotiation is $0 if the firm initiates the negotiation,
and is $10(for the neighborhood) if the neighborhood initiates. Do the
Coase Theorem's result still hold?(10%)
2.Consider the divergent expectation theory of litigation. Explain why
(1)Increase in litigation cost(for either plaintiff or defendant) encourages;
(2)settlement is less likely when either party is more optimistic regarding
litigation outcome; and(3)risk aversion increases settlement possibility.(15
%)(The best way to answer the question is to draw pictures.)
3.The probability of an accident(which causes a damage of $300 to the victim
if occurs) is a function of the care levels of the potential perpetator (P)
and the victim (V), and is captured in the following table.
╭───────┬───────┬───────────╮
│P's care level│V's care level│ prob. of accident │
├───────┼───────┼───────────┤
│ L │ L │ 0.5 │
├───────┼───────┼───────────┤
│ L │ H │ 0.4 │
├───────┼───────┼───────────┤
│ H │ L │ 0.42 │
├───────┼───────┼───────────┤
│ H │ H │ 0.35 │
└───────┴───────┴───────────┘
The cost of high and low levels of care are $30 and $10 for P; and are $25
and $20 for V. Consider the 4 liability rules: strict liability, no
liability,negligence with defence of contributory negligence and liability
with defence of contributory negligence. Which rule(s) implement(s) the
social optimum?(40%)
