One of the eigenvalues is close to 0/0

Postby fda » Fri Sep 30, 2016 6:53 pm

Hello jpfeifer,
I run a model but this model have an error:
??? Error using ==> print_info at 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 at 76
print_info(info, options.noprint);

Error in ==> calib711nobd at 493
oo_.dr.eigval = check(M_,options_,oo_);
I don't know how to solve this problem?

model_diagnostics returns a whole bunch of collinearity warnings, but my first guess is numerical problems. The differences between your steady state values for various variables are highly implausible. If
Z=1 and L =0.22, K usually cannot be K=78303.73. I would recheck the steady state computation or use a nonlinear model that assures consistency.
In any case, you should alway start with a simple model that works. Finding the problem in your big model will be extremely challenging.
