Subject   st: creating constraints in panel data

Dear Stata users,

I hope you can help me. I am trying to estimate a cobb-douglas function
(Y=X1^a*X2^b*X3^c*....) using panel data with fixed effects.

I am using the log of the production function as my functional form,
that is, Ln(Y) = aLn(X1) + bLn(X2) + cLn(X3)+....

And I need to assume that the sum of the exponentials must be equal to 1

Can I make such constraint for panel data models? I know I can use
"cnsreg" command, but this is not panel data estimation, and it is not
valid in may case.

Thank you very much,
