Impossible to find the steady state (the sum of square residuals of the static equations is
11.6413). Either the model doesn’t have a steady state, there are an infinity of steady states,
or the guess values are too far from the solution

2

If I may ask, what type of model are you running…?

3

nk-dsge model

4

Oh ok. If you wrote the model from scratch, maybe you can start from some baseline NK model that works and extend it little by little…

5

yes,dear!I did follow your advice to do it!but i’m really confused about the codes,could you please solve the problems? many thanks!

6

Oh ok. If you add features little by little, I guess you could know which stage the problem occurred, and then try to find out what caused it.

7

For a model that size, I would recommend either starting with a simpler model that works or computing the steady state analytically. In any case, without the file it is impossible to tell what is going on.

sorry,professor.I put the file there.

I am getting

ERROR: There are 41 equations but 40 endogenous variables!

oh!sorry professor! I forget it.thanks so much!
