Steady state problems

Dear All,

I would have a question…
We had improved a DSGE model in Matlab and decided to solve it in Dynare as well. We computed the linearised equations and the steady state values (as initval) - from our previous Matlab results. I’m wondering why Dynare cannot solve the problem but sends the following message:

'Impossible to find the steady state. Either the model doesn’t have a unique steady state of the guess values are too far from the solution

Thanks in advance
Agnes
