Hi I am trying to run the attached code to solve for ramsey policy.

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. ---

Good afternoon, I am writting here because I am currently experiencing the same problem.

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. ---

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? ---
