Dear all:

I try the code in 4.2.4 and the error message is as following and by the way the steady state values are calculated by other software so the outcome of steady is same as intial value because Dynare’s calculation is very sensitive to the intial value and the outcome is different every time I run the code(when I do not set the intial values same as outcomes):

Also,I try many different combinations of values of prior parameters setting as recommended in previous related topics but seems still does not work.

Does this mean that there is some fundmental error with my model setting ?

Thank you all for potential suggestions !

Dear Professor:

Thank you very much.

But there is new problem now:

SOLVE: Iteration 9(and 10,12 18 and so on)

Spurious convergence.

and in the small window"turning of the scale parameter" shows that acceptance rates is always 0.0000000

what does this mean (problem with steady state or estimation)? Thanks in advance!

It means that Dynare was able to compute the steady state for the initial parameters but cannot compute it for the new parameters in the MCMC draws during estimation. You might need to provide an analytical steady state in the initval block or a separate steady state file.

Dear Professor:

Thank you very much for your kindly help.I will try what you suggest.

Dear Professor:

I try to write a matlab program to calculate the steady state in a separated file (since there is no analytical solutions) but now there is new error message.Whay should I do ?
