摘要

在個體理論及探討廠商行為的文獻中，成本極小及利潤最大，是被普遍採用的行為假設。在這篇文章中，我們探討當廠商具備及不具備技術無效率時，如何以translog的系統方程式，估計成本模型及利潤模型。我們也提出檢測成本極小假設和利潤極大假設的方法。我們以美國航空業的資料作為實證範例。

Cost minimization and profit maximization behavioral assumptions are most widely used in microeconomic theory to analyze firm behavior. In this paper we address estimation of a translog cost and profit systems with and without technical inefficiency. We also test whether cost minimization or profit maximization hypothesis is appropriate for a given data. The technique is illustrated using a panel data for the US airlines.
