technical inefficiency with determinants and marginal effects

[ABIBA PATOUOKOUMCHE]

I am doing research in tax efficiency. I would like to determine tax effort (persistent and transient including determinants) and marginal effect.

I would like to use the Kumbhakar et al, 2018 model explained in this article "panel data stochastic frontier model with determinants of persistent and transient inefficiency".

I have "a practictioner's Guide to Stochastic frontier Analysis using STATA '' 2015 but the authors don't explain how to figure out persistent with determinants, transient with determinants and marginal effects. I attached to this message the article.

Please, I would like to know what command in STATA could I use. What packages do I need ? or what commands should I use to estimate persistent, transient and marginal effects?

Thanks, I really need your help.

I do not believe that the estimation method employed in the article that you attach has been programmed in Stata. But we implement a simpler multi-step procedure in this paper using Stata. You can have a look at our do-files.

Hey Andrew Musau ,

I read your paper and I was interested in using the same approach. However, I did not find your do-files for that paper. Could you please share them?

Thanks!
