st: ACKERBERG-CAVES-FRAZER PRODUCTION FUNCTION

[Dario Pozzoli <dariopozz@gmail.com>]

Hi everyone,


I am estimating a production function using the Levinsohn and Petrin
approach and I would like to implement the ACKERBERG-CAVES-FRAZER
(ACF) one too.

Does anyone know how to modify the levpet code in stata to estimate
the labour coefficient in the second step as ACF suggest?

Best Wishes

Dario
