I would like to ask question about writing variable in Dynare . In my model (optimal fiscal policy under commodity price shock) I have one equation (sovereign fund ) about law of motion for stock of asset Ft+1=Ft+Tt
Where Ft+1 is stock of asset in t+1 time and Ft is stock of asset in t time and Tt is oil revenue in time t . It means country put oil revenue which it earns in time t in sovereign fund and then stock of asset accumulation rule is set as above.
I would like to ask when I write this equation I should write Ft+1 variable as a F (not F(+1)) which is like writing capital .
Thanks from now
