兩個相同成本的廠商進行貿易？ - 經濟

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
