Hi.

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.
