Two-tiered Stochastic Frontier Analysis

[Gaetano Francesco Coppeta]

Hello to everyone,

I am working on application of the two-tier stochastic frontier (Polachek and Yoon 1987). I was wondering if anyone could give me suggestions on how to perform the analysis with Stata.

Browsing the internet, looking for information, I came across some papers that make mention of some ado files, but I couldn't find it.

I hope any of you can help me

Hi,

I am currently working with the two-tier stochastic frontier model. I am aware of the sftt command for cross-sectional data (Lian, Y., Liu, C., & Parmeter, C. F. (2023). Two-tier stochastic frontier analysis using Stata. The Stata Journal, 23(1), 197-229). However, I am unsure how to apply this framework to panel data.

I would greatly appreciate any assistance you can provide.

Thank you!
