摘要

本文嘗試利用一個獨占模型，以研究廠商經營所面臨的不確定性與生產技術伸縮性間之關係。我們將廠商的營運過程分成兩個階段，並將伸縮性當成一個內生性變數，此時，廠商首先在事前的投資階段決定生產函數所具有伸縮性的大小，其次，則在事後的生產階段決定產出。結論顯示“價格波動幅度增加會使獨占者採取較具伸縮性之成本結構，而使廠商平均成本線愈為平坦。此外，獨占廠商在價格波動情形下的期望產出則大於價格穩定情形下的產出，反映在新進者無法進入市場的前提下，價格波動幅度增加，透過凸性的利潤函數，會使廠商的期望利潤增加。

This article uses a monopoly model to investigate the relation between flexibility and uncertainty. The evidences presented show that the greater is price variation, the higher the degree of flexibility. This conclusion is consistent with the finding of competitive model. On the other hand, our model shows that with fluctuations expected output for the monopolistic firm is larger than the output in the absence of uncertainty. This fact reflects a convex profit function.
