不知道可不可以這樣解釋呢.....
獨占市場的達到均衡時 必為柏拉圖最適
但比起完全競爭 社會將多了一塊無謂損失
那一塊DWL使得獨佔市場不如完全競爭那樣有效率
所以相對而言 獨占市場是less efficiency
(但對獨占市場他自己而言 達到均衡 即為efficiency)
不知道這樣講有沒有錯...
如果有錯歡迎指正喔 ^ ^"
※ 引述《adambrody (adambrody)》之銘言:
: i just got a little confused:
: We always compare monopoly to perfect competition.
: BUT ,According to Pareto's definition ,
: if we can not improve consumers' welfare without hurting profits of a firm,
: WHY we say a monopoly structure is INefficiency?
