    formula 25

“f=1-(mean(q)mean(k)/(nuqk))((kappagomegag-kappalomegal)/(kappag*omegag))”

the k means the mean value of capital, i maybe need the external function,but i do not work.

the D bar means the steady of the D. so i need to compute the steady state first and get the steady number of D.

I think, you could try steady_state(q) to represent the steady value.

f=1-(steady_state(q)*steady_state(k)/(nuqk))((kappagomegag-kappalomegal)/(kappag*omegag))
