Suppose a worker at a computer company rearranges existing machines and labor and
increases production in the process. Using the production function, with output on the
vertical axis and labor on the horizontal axis, this would be described as
an upward shift of the curve combined with an upward movement along the curve.
a movement upward along the curve.
a movement downward along the curve.
a downward shift of the curve.
an upward shift of the curve.
Because marginal product decreases as input is increased
nothing is implied about how much input is required to produce one more unit of output.
it takes decreasing amounts of input to produce one more unit of output.
it takes increasing amounts of input to produce one more unit of output.
the amount of input it takes to produce one more unit of output does not change.
it takes zero input to produce one more unit of output.

The chance a firm takes in defecting form a cooperative solution to a game is that

In looking at the distribution of income provided by quintile statistics and the Lorenz
curve, it must be kept in mind that
all individuals with high incomes have a lot of wealth, whereas all individuals with
low incomes have very little wealth.
those who are poor generally stay poor, and those who are rich generally stay rich.
when families split up, the two new families formed move down in terms of income
into lower quintiles.
income per person is being measured.

agreement.
both parties are willing to negotiate with each other
transactions costs of an agreement are high compared to the costs of the externality
itself.
Emission taxes have an advantage over taxes on production in that
they change the firm's output whereas taxes on production do not.

they do not raise the firm's prices whereas taxes on production do.
the firm can increase the amount of pollution associated with a given amount of
production.

Firm X and firm Y are the only two Internet providers in a small town. The demand for
Internet subscriptions is P = 60 −Q . Neither firm X nor firm Y has any fixed costs.
The marginal cost of firm X is constant at $10, and the marginal cost of firm Y is
constant at $20. Each firm can sell either 10 or 20 subscriptions, and they meet only
once in this market.

在一古董拍賣會中,有貨真價實的「老」古董,也有乍看之下具有價值但實為新
品的「新」古董。假設老古董最低願意出售價格為20 萬元,新古董最低願意出售
價格為15 萬元,而買方願意出價25 萬元來購買老古董,18 萬元來購買新古董。
若在今日之拍賣會中,共有約80 件古董欲出售,試問老古董約至少有多少件(或
佔多少比例),這些老古董的擁有者才會願意割愛?(15%)
