两级随机前沿模型的两次复制研究
Two Two‐Tier Stochastic Frontier Replications
摘要
We replicate the two foundational studies which proposed the two‐tier stochastic frontier model, first in the cross‐sectional setting and then for the fixed effects panel data model. We explore matters of software then and now, different mathematical formulations of the likelihood, and alternative current software tools. We also highlight several data issues that arose in both replications.
中文摘要
我们复现了两项开创性研究，这些研究首次提出了双层随机前沿模型，先是在截面设定下，随后应用于固定效应面板数据模型。我们探讨了当时与现在的软件问题、似然函数的不同数学表述，以及当前可用的替代软件工具。同时，我们指出了两次复现过程中出现的若干数据问题。
