【摘要】 为了刻画潜在的空间效应,本文提出了一类空间滞后随机前沿模型.在单边误差项分别服从半正态分布、指数分布及截尾正态分布的情况下,我们给出了模型的对数似然函数及迭代步骤.此外,应用JMLS方法给出了单边误差项的条件均值与条件众数,因而得到了相应的技术效率估计.更多还原

【Abstract】 This paper proposes a stochastic frontier model with spatial lag variable to account for potential spatial effects.We proposed the log-likelihood functions and the iterative steps with three different distributions for the one-sided disturbance term,the half-normal,the exponential and the truncated normal. Besides,using JMLS,we educes the conditional expectation and conditional mode of the one-side error term to estimate technical inefficiency.更多还原
