[考試] 兩個相同成本的廠商進行貿易？
Suppos there are two countries. In the same industry, each country has only
one producer. Producers produce the same good. Two producers have the same
cost function and face the same demand function, Suppose there is
international trade between two countries and producers choose output to
maxmize profit. there is also no collusion between firms.
(a) compared with the scenario when there is no trade, the price charged
by a firm is larger.
(b) compared with the scenario when there is no trade, the production level
of each firm is larger.
(c) compared with the scenario when there is no trade, the deadweight
loss is larger.
(d) compared with the scenario when there is no trade, the profit of each
firm increase.
我的想法是If there is no trade, 則廠商就是獨占市場，當然訂高價囉， 所以選(A)囉
可是下面的(B)、(C)、(D)怎麼算呢 >"< 暈倒
