Dynare forums

Dear All,

I'm running my model with dynare and getting error message as follows:

STEADY: The Jacobian contains Inf or NaN. The problem arises from:

STEADY: Derivative of Equation 2 with respect to Variable c_h (initial value of c_h: 0.61)
STEADY: Derivative of Equation 5 with respect to Variable c_h (initial value of c_h: 0.61)

STEADY: Derivative of Equation 2 with respect to Variable phi_h (initial value of phi_h: 17.03)
STEADY: Derivative of Equation 3 with respect to Variable phi_h (initial value of phi_h: 17.03)
STEADY: Derivative of Equation 5 with respect to Variable phi_h (initial value of phi_h: 17.03)
STEADY: Derivative of Equation 12 with respect to Variable phi_h (initial value of phi_h: 17.03)
STEADY: Derivative of Equation 3 with respect to Variable x (initial value of x: 2.727)
STEADY: Derivative of Equation 12 with respect to Variable d (initial value of d: 1.282)
STEADY: Derivative of Equation 3 with respect to Variable l_h (initial value of l_h: 0.019)
STEADY: Derivative of Equation 5 with respect to Variable r_d (initial value of r_d: 12.23)
STEADY: Derivative of Equation 12 with respect to Variable r_d (initial value of r_d: 12.23)
STEADY: Derivative of Equation 6 with respect to Variable c_e (initial value of c_e: 0.18)
STEADY: Derivative of Equation 18 with respect to Variable c_e (initial value of c_e: 0.18)
STEADY: Derivative of Equation 12 with respect to Variable s (initial value of s: 9.145)

STEADY: Derivative of Equation 12 with respect to Variable l_b (initial value of l_b: 11.098)
STEADY: Derivative of Equation 12 with respect to Variable r_p (initial value of r_p: 12.75)
STEADY: Derivative of Equation 6 with respect to Variable (initial value of : 0)
STEADY: Derivative of Equation 3 with respect to Variable w (initial value of w: 0)
STEADY: Derivative of Equation 18 with respect to Variable h_h (initial value of h_h: 0)

STEADY: Derivative of Equation 12 with respect to Variable s (initial value of s: 0)
STEADY: Derivative of Equation 12 with respect to Variable c_e (initial value of c_e: 0)
STEADY: Derivative of Equation 12 with respect to Variable r_d (initial value of r_d: 0)

STEADY: The problem most often occurs, because a variable with
STEADY: exponent smaller than 1 has been initialized to 0. Taking the derivative
STEADY: and evaluating it at the steady state then results in a division by 0.

How to solve that problem?

Hope your help.
Thanks in advance

check your equations. For example in equation 2, you divide by rlh_ss, but this parameter is 0. Put

Code: Select all

resid;

before steady and follow all equations that have NaNs.

Dear All,

Thank you Johannes Pfeifer for the suggestion before. But after I changed the initial value, the problem as follows :

Maximum number of iterations reached:
increase options.MaxIter.

Residuals of the static equations:

Equation number 1 : 1.1133
Equation number 2 : -0.28936
Equation number 3 : -0.66412
Equation number 4 : -3.0979

??? Error using ==> print_info at 74
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

Error in ==> steady at 92
print_info(info,options_.noprint, options_);

Whats the problem of this estimation ? I've tried change the initial value but always receive this error message.
Hope your help.

Thanks in advance

Please sit down and rethink what you are doing here. It seems you are mixing linearized equations with nonlinear ones. This generally makes not much sense and risks making inconsistent choices, because some parameters are functions of the steady state values for the variables that you are trying to determine.
