固定市場範圍情況下的簡單空間定價策略之經濟效益分析

關於固定市場範圍情況下的兩類型單一定價策略之經濟效益分析，Cheung 與Wang (1996)指出在固定市場範圍下，需求函數的型態可以決定兩類型單一定價經濟效益的優劣，在特殊條件成立下。首先，我們檢視Cheung 與Wang (1996)命題中的特殊條件。再者，我們重新探討在固定市場範圍情況下需求函數的型態對兩類型單一定價策略經濟效益的影響。最後結果發現，現在固定市場範圍下，除了利潤會受到需求函數型態的影響外；需求函數的型態無法完全決定兩類型單一定價策略產出與社會福利的優劣。換言之，分析兩類型單一定價策略時，經濟空間扮演著極為重要的角色，而需求函數非唯一的決定因素。

According to related studies about simple monopoly spatial price theory, Cheung and Wang (1996) show that, the shape of demand function can fully determine the relative economic advantages between two simple spatial pricing policies in a world with fixed market area, provided other respective condition are satisfied. First, we examine other respective condition of Cheung and Wang (1996). Second, we reexamine this general context between the shape of the demand function and two simple pricing policies. Finally, the most important, we find the shape of the demand function cannot fully determine the total output and social welfare between FOB and CIF pricing with fixed market area. In other words, when we are compare relative economic benefits between two simple pricing policies, the economic space plays an important role, the shape of the demand function is not the main factor.
