A few ides for question 1:
1. Generate dummies and then use -cnsreg-
2. Use Jeroen Weesie's -linest- with -xtreg-
3. Since you are estimating a production function, you might find Stata's
-frontier-, -xtfrontier-, or -levpet- (from SJ4-2) commands useful. Both
-frontier- and -xtfrontier- allow linear constraints.
Hope this helps,
Scott

Subject: st: cnsreg with panel daya
Dear List members
I am a new Stata user and have two related questions concerning constrained
regression in panel data setttings.
1) My first question: Is it possible to estimated xtreg commands using
cnsreg, or are there other ways of estimating constrained linear panel
models? (For economists on the list, the example I have in mind is of
imposing the constraint of constant returns to scale on a panel production
function)
