Hi
I am trying to run the attached code to solve for ramsey policy. When I run the code in MATLAB, I get the following.

dynare C:\dynare\4.1.3\work\leviathancomp\leviathanopt-ramsey.mod

So I do have some computations but program stops with the above error message. Any suggestions? I am using MATLAB 7.10.0(R2010a).

There are many problems. For starters:
[ul]
] Don’t use a hyphen “-” in the filename. It gives you the mentioned error./:m]
*] The syntax is

planner_discount=DOUBLE;
which means you have to substitute a number for DOUBLE. By default, it is

planner_discount=1;/*:m]
*] Add

steady; check;
after the initval block to compute the steady state from the initial values ./*:m]
]Dynare cannot handle inequality constraints like the first one./:m]
*] You did not specify an initial value for q.The default starting value for the steady state search is then 0.

q^(-a-1)
will give you an error as the exponent is negative and hence you would have a division by 0./*:m][/ul]

Thanks for the response. I will try making those changes and run it again.

Ok. So i made the changes you suggested and I still keep on getting the following error:

I am attaching the corrected mod file. Let me know if you think of something.

Good afternoon,

I am writting here because I am currently experiencing the same problem. I tried all the solutions mentioned above, I reinstalled Dynare, tried several versions, and created a dedicated “work” subfile.

Here is the complete Matlab output. I am using a student version, 7.10.0 (R2010a)

EDU>> addpath c:\dynare\4.1.0\matlab
EDU>> cd c:\dynare\work
EDU>> dynare CashInAdvanceModel-1

??? Error using ==> evalin
Undefined function or variable ‘CashInAdvanceModel’.

Error in ==> dynare at 132
evalin(‘base’,fname) ;

It seems to me that the problem comes from that Matlab doesn’t recognize the “CashInAdvanceModel” function which is defined in the .mod file

This is really frustrating because I have been stuck with this issue for a couple of hours and I can’t finish my work…

I really appreciate your help,

Thank you for your time and consideration.

Best regards,

Julien

First, only use alphanumeric characters in the filename. So do not use a “-”.
Second, in the mod-file, delete the last for loop. The “%” used for defining the string format interferes with Matlab’s use of % for comments, when preprocessing with Dynare.

Hi,

i am using Dynare 4.2.4 and Matlab 7.12.0 (R2011a) and i set path to the directory c:\dynare\4.2.4\matlab but still have the same problem:

??? Error: Unexpected MATLAB operator.

Error in ==> dynare at 120
evalin(‘base’,fname) ;

what can i do to fix this?

Thanks

The command

works fine for me. Did you rename the mod-file before uploading it?

merdogul · January 22, 2012, 10:53pm

Hi,

i did not change the file name but recognize that i wrote wrong command to run the code.

thank you very much…

Why are there @ signs in you file?

Hello,

I am trying to run the attached file but I keep on receiving this error message:

??? Error using ==> sigma at 83
Not enough input arguments.

Error in ==> RBClevels2nd at 102
set_param_value(‘sigma’,sigma)

Error in ==> dynare at 180

I am spending a lot of time on it, could you please provide any help with it?

Thank you.

jpfeifer · November 6, 2014, 11:09am

Matlab does not know sigma and tries to call the function called sigma. Are you sure that the file you load actually contains a parameter named sigma?

Nemo4t · November 6, 2014, 11:38am

Even if I give some value to sigma (0.07) and nu (3) it doesn’t work

jpfeifer · November 6, 2014, 11:55am

The attached file works on my machine. Did you forget the semicolon at the end of the line?

Great! I don’t really know how you did it, but It works!

Tanks a lot!

Nemo4t · November 10, 2014, 10:22am

On the same model I would like to display (and eventually manage) the time varing policy matrix.
I tried different solutions but I just couldn’t, can anyone help me with it?

jpfeifer · November 10, 2014, 4:48pm

What do you mean with

?

Nemo4t · November 11, 2014, 8:35am

I mean the G3 matrix in the model 3rd order aproximated.
