標題[考試] 兩個相同成本的廠商進行貿易？
時間Thu Feb 7 15:57:52 2013
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

2F：→ Dukoff:說兩市場的兩獨佔廠商若有勾結，相對於完全沒勾結之下，會 02/08 16:14
3F：→ Dukoff:有怎樣的差異。且題目好像不是四題都要算出來。 02/08 16:15
4F：推 moondark92:各國有唯一獨佔廠商,國家間發生貿易後和沒貿易前比較 02/08 18:16
5F：→ moondark92:市場融合,需求曲線水平加總,然後獨佔變寡(雙)佔 02/08 18:18
6F：→ moondark92:由於兩國原需求和成本函數都相同,原來產量和價格應同 02/08 18:20
7F：→ moondark92:市場結合後若二者皆維持產量不變如同獨佔廠商結合結果 02/08 18:22
8F：→ moondark92:但任一廠商片面增加產量皆可增加利潤...... 02/08 18:22
