Problem using predict with prodest

[Cem Ozdemir]

Hello everyone,

I am having trouble when trying to use predict in

prodest

.

I have a panel dataset where firms are recorded over years. This is an unbalanced panel. For each firm I can observe the wage bill, material costs, sales, investment, and capital. My aim is to get TFP measures which are the residuals from the estimated production function.

In order to estimate the production function I am using -prodest-. However, due to data-security measures, one cannot apply -ssc install prodest- because there is no internet access, hence I've downloaded the program from the link

http://fmwww.bc.edu/repec/bocode/p/prodest.ado

and installed the program offline.

This is my code below:

xtset firm year
prodest sales, method(lp) free(wage) proxy(material) state(lcap) control(year industryyear) acf attrition
predict tfp, residuals

However, I get the following error:
"command prodest_p is unrecognized"

The regression goes through but I can not use -predict- to get the residuals. When I implement the same code with network access on fake data and install -prodest- through -ssc install prodest- it works.

I would really appreciate if anyone can help!

prodest_p is a different ado file. need it too.
