I want to enter the codes of investmen Adjustment cost equation in Dynare.
Model is not in log-linear form.
I do not know how
to enter S(It/It-1) and S’(It/It-1) and S"(It/It-1) in Dynare.
It is investment in time t.
It-1 is investment in time t-1.
S’ is the first derivative and S" is the second derivate.
