Hi,

I am trying to solve my model non-linearly (the mod file is attached), but I've got the following error message
"Error using print_info (line 52)
One of the eigenvalues is close to 0/0 (the absolute value of numerator and denominator is
smaller than 1e-6)
Error in check (line 76)
print_info(info, options.noprint);
Error in Model (line 537)
oo_.dr.eigval = check(M_,options_,oo_);
Error in dynare (line 120)
evalin('base',fname) ;"

I guess it can be solved if I re-parameterize, although I am not sure which exactly parameters I need to change given the complexity of model. Is there any way to figure it out or somehow fix this issue?

Thank you

It's not about parameters, but a deeper issue.

Code: Select all: model_diagnostics(M_,options_,oo_)

says

model_diagnostic: the Jacobian of the static model is singular
