No steady state and NO IRF RESULTS

Thank you sir. Could you please suggest what contemporaneous variables ?

What do you mean with

All variables in your model must appear at time t. Otherwise they cannot be determined.

Thank you, Sir. BUT I meant asking precisely in terms of my model what changes should I make while treating inflation expectations exogenous.

ALSO, I JUST HAVE SAMPLE SIZE 15 FOR THIS MODEL. WHEN I RUN TSLS IN EVIEWS 11, IT SAYS THAT THE NUMBER OF VARIABLES is LESS.
CAN I DETERMINE THE PARAMETER VALUES FOR THIS MODEL IN DYNARE WITH SAMPLE PERIOD SIZE 15

I cannot answer that as I can only provide technical advice. It is your model and you need to decide how expectations are formed.
Regarding estimation: See e.g.

Sorry for the late response sir. Thank You very much for the information.
