The Silence Bleating! of the Lambdas: Comment
指出Alston和Chalfant的函数形式最小二乘检验有偏，推导了适用于单变量和多变量回归模型的有效检验，并提出了处理内生预算份额的估计方法，结论是他们的数据不支持对LA-AIDS模型的强烈否定。
Abstract Alston and Chalfant…s least squares test for functional form is biased. A valid test is derived for both univariate and multivariate regression models. An estimation method to account for endogenous left‐ and right‐hand‐side current‐period budget shares in the Rotterdam and LA‐AIDS models is presented. Alston and Chalfant…s strenuous rejection of the LA‐AIDS model in favor of the Rotterdam model is not supported by their data.
