Dear all,
I had two questions regarding the estimation of a production function.
1) When using the 'opreg' command (Olley and Pakes approach), does anyone know how to predict the productivity measure resulting from that regression? It seems that 'predict newvar, omega' does not work with 'opreg' (in contrary to 'levpet')
2) How can one implement the approach described by Gandhi, Navarro, Rivers (described in their paper: "On the identification of production functions: How heterogeneous is productivity?" in Stata?
Thank you in advance for your answers,
Jordi
