(1) is incorrect, because it is illegal syntax. Stata won't know what to do with the unmatched quotes. 

(2) is legal syntax. I can't say whether it is correct for your problem, but provided all the locals are defined, it looks OK to me. 

But it is better to get Stata to tell you this.

Sorry, I am a little confused. Two expressions:

(1)   replace `lnc'=`a'*`lnpe'+`b'*``lnpe'*`lnpe''


(2)   replace `lnc'=`a'*`lnpe'+`b'*`lnpe'*`lnpe'


Which is the correct one?
