Predetermined variable assumption in cee

i noticed that in CEE (Nominal Rigidities and the Dynamic Effects of a
Shock to Monetary Policy) the author analyse the role of timing assumption .they first made the assumption that consumption, investment and capital utilization are predetermined variables.and then they drop the assumption to see the difference. I want to know how to implement this in dynare?
just add the command
predetermined_variables c i u;
run the model and delete it and run it again? or you have to modify the model equation. thanks a lot!

No, that is not the way to go. These variables are not predetermined, but rather their expectations is taken with respect to a different information set. This can be done with Dynare’s Expectation operator. See e.g. Two country open economy (Corsetti & Pesenti, 2001)
