Dear
I am Zhangyan, a PhD candidate in Economics.
I am using levpet to calculate TFP. But stata said
"
. tsset frdm year
panel variable: frdm (unbalanced)
time variable: year, 2005 to 2007, but with gaps
delta: 1 unit
. levpet lnva, free( lncyry lnage) proxy( lnzjtrj) capital(lngdzch) valueadded i
(frdm) t(year) reps(250)
repeated time values within panel
r(451);
"
I have calculate TFP using OP method. Now i want to use intermediate input to
solve the simultaneous problem.
Would you do me a favor? Thanks a lot!
Best regards!
