Dynare forums

Hello every one,
I Have a financial model that I have simplified it to analyse some effects. It is very simple model and I provide external m file to find steady state. When I use external steady state file with the format : filename_steadystate.m , dynare gets an error :

Error using print_info (line 72)
The steadystate file did not compute the steady state.

and I have very small res : like Equation number 9 : 3.2628e-06 for just two variables.

when I remove steady state file and use intval with the values calculated by my external file with "steady(solve_algo = 1)", I have the same problem, but with "steady(solve_algo = 2);" or commenting out "steady" dynare can find the steady state.
Because I would like to make a loop for parameter "theta" with "set_param_value('theta',i);", in the second case I have steady state problem, so It seems I have to use external file to find steady state!
I could not find where is the problem, and why dynare gets error for the tiny residual like -1.4996e-05.
I put the mod file and external steady state here. It is appreciated if you reply at your earliest convenience.
Sincerely,

Dear Prof. jpfeifer,
Would you please help me with this issue! I really stuck a the moment! and I cannot go far!
Sincerely,

I don't understand the problem. Why don't you use the unstable version with

Code: Select all

steady(solve_algo = 4,maxit=1000);


That easily works with your file. Using a steady state file to use a numerical solver seems like an overkill. But if you want to got his route, the solution is to increase the precision of your solver by using

Code: Select all

options=optimset('TolFun',1e-12);
[V,fval]=fsolve(@(x) MN1(x(1),x(2)) ,[1,100],options);


Dear Prof. jpfeifer,
Thank you very much. it solved the problem.

Dear Professor jpfeifer,
In order to solve the previous problem, I got an error: I would like to see how the model changes with changing in "x", so I have added the last part "set_param". when I comment out it and manually change "x"value, dynare works well, but when I use "set_param_value" , dynare tells me it cannot find the steady state. May I ask you what is the problem, and how I could get rid of? It seems when the new variable value is set , for the second stoc_simul, Dynare doesn't use steady state file or the steady state file can't get the new value!
Sincerely,

That is a clear sign you do not take all parameter dependencies into account. You vary x, but you only once set

Code: Select all

d=(1-sigmaa)*(1-x);


before the model block. That will not work.
