dear all:
Hello! I’m new. I can’t find the steady state of my model. Could you help me?

Residuals of the static equations:

Equation number 1 : 0 : lamda

Equation number 4 : 0 : q
Equation number 5 : 0 : k
Equation number 6 : 0 : y1

Impossible to find the steady state (the sum of square residuals of the static equations is
3195.4417). 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

many thanks!!!

Put resid before other calls to commands to see that there is a residual

Equation number 21 : -0.079492 : Xat

So it seems your system in equations 21 to 24 is problematic.

many thanks,dear professor!!

Dear prfessor
When I choose the the order in “stoch_simul(order=2,irf=40) ;” to be 2,the dynare Warning: the matrix is close to singular value, or scaling error. The results may not be accurate ,what should to solve this problem?

The message is most likely caused by the unit roots in the model. Also note that at order=2 the shock variances matter. You set them to 100 percent. I am again attaching a steady state file compatible with Dynare 5.3.
