提出加性一般误差模型,将误差设定作为优化模型的一部分,而非事后添加线性误差项,实证表明该模型优于标准超越对数模型。

Abstract

Many empirical studies of production specify a deterministic model of the firm, derive the implied behavioral equat ions (input demand or share system), and then "embed this system in a stochastic framework" by tacking on linear error terms. In contras t, this paper proposes general error models (GEMs) in which the error specification is an integral part of the optimization model. These m odels are the statistical embodiment of Stigler's view that apparent observed inefficiencies reflect the investigator's ignorance of the t rue optimization problems. Additive GEMs are proposed and interpreted Specification tests indicate that a translog additive GEM is superi or to the standard translog specification.
