Can't find steady State for OLG model with 60 cohorts

[YUYI]

Hi

This is my first time using Dynare. I am trying to apply a shock to my OLG model which has 60 cohort; therefore I have 60 states to solve for the IRF. The initial steady state with shock has been solved through an OLG model built in Matlab, which is input into Dynare.

Running the Dynare model, I get the following message:

??? Error using ==> print_info at 57
Impossible to find the steady state. Either the model doesn't have a steady state,
there are an infinity of steady states, or the guess values are too far from the
solution.

Looking at the output of the residual of the static equations, I believe the error is related to the euler equations. I am not sure what could be wrong, I appreciate any help on this or if someone could send me an example of RBC model with many agents as an example. Attached is my OLG model.

Cheers,

Yuyi

With the development version I get the error message:

STEADY: and evaluating it at the steady state then results in a division by 0.
Error using dynare_solve (line 60)
An element of the Jacobian is not finite or NaN

Thus, please provide valid starting values.

Many thanks.

I realized I need to also initialize the steady state for other variables I have declared.
