i am trying to replicate the SW AER 2007 paper using dynare version 4.2.0 in the mod file, SW use a command #usmodel\_stst (to call the m file in the syntax modfilename\_stst that defines steady state restrictions on the estimated parameters) however this seems to be causing the error message: ERROR: usmodel.mod:83.1: syntax error, unexpected ‘#’, expecting EQUAL has anybody encountered this problem? thanks reuben ---

I guess that this was written using Dynare 3. This construct is no longer valid under Dynare 4, but you may obtain the same result using the “external\_function” command. I cannot be more precise without more details on your problem (I don’t have the MOD file you’re talking about). Best, ---
