Lots thanks!

It says there is a problem in line 116, column 34. Maybe there is a missing bracket.

dear jpfeifer,

Yes, you are right. I fixed it.

Thank you very much indeed!

Dear Jpfeifer,

Thanks a lot first.

When I run my code(riksbank model by Adolfson et al (2005), the following errors took place:
Starting Dynare ...
Starting preprocessing of the model file ...

Could you give me some advice?

Thanks!

Enter the steady state manually. And check for errors in the code.

Dear Jpferier,

Thanks!
I did enter the steady state annually, but how to check the error?
The code is attached. Please give me some advice!

Thank you very much indeed!

But with the posted model, Dynare says

ERROR: There are 86 equations but 95 endogenous variables!

As a follow-up to this, the following endogenous variables are not determined by the model's equations:
wbar, h, pid, pfaiz, v, gamf, rstar, ystar, pistar

Dear Jpfeifer,

Thanks. I got my problem.

Dear Donihue,

Thanks for your kind help!
I will check my code in detail following up to your reminders.

Dear Jpferier,

Thanks for your help.
When I run another version of RIKSBANK Open DSGE model, I met the following errors:

"ERROR: ea_sr07try.mod:20.1-10: syntax error, unexpected PARAMETERS"

but all parameters are defined and used later?

Could you give me a hand?

P.S: "//Y=C+I;" is a comment or an equation?

The // indicates a parameter. Check if there is a semicolon at the end of line 19.

Dear Jpfeifer,

Thanks for your help.
I modified my code and it met the condition. but another problem occured when I ran the code as:
"...

The rank condition is verified.

Improvement on iteration 43 = 0.000000000

Objective function at mode: -1899.896983

POSTERIOR KERNEL OPTIMIZATION PROBLEM!
(minus) the hessian matrix at the "mode" is not positive definite!
=> posterior variance of the estimated parameters are not positive.
You should try to change the initial values of the parameters using
the estimated_params_init block, or use another optimization routine.
