The steady state contains NaN or Inf

Dynare help (legacy posts)

Dear all,
I am a greenhand in practicing dynare. I have read some posts and found similar questions, however, I still cound’t solve my problem :frowning:
so my apologies if this has been dealt with already. Please help me.

I got an error message which is showing like:

Warning: Some of the parameters have no value (pai_ss, adj_B_ss, rb_ss, rd_ss, r_ss,
Rb_ss, Kb_B_ss, D_B_ss, jb_Kb_ss, Kb_k_ss, adj_k_ss, T_k_ss, G_B_ss, T_B_ss, y_B_ss)
when using steady. If these parameters are not initialized in a steadystate file, Dynare
may not be able to solve the model…

As it says: if you are not providing numerical values for the parameters

[quote]pai_ss, adj_B_ss, rb_ss, rd_ss, r_ss,
Rb_ss, Kb_B_ss, D_B_ss, jb_Kb_ss, Kb_k_ss, adj_k_ss, T_k_ss, G_B_ss, T_B_ss, y_B_ss[/quote]

Dynare cannot compute the steady state. Your problem is the non-recursive specification of parameters.

In the line

rd_ss=eps_d/(eps_d-1)*r_ss; //5 rb_ss=eps_b/(eps_b-1)*Rb_ss; //6 Rb_ss=r_ss+eta_ss-ka_kb*(Kb_B_ss-vb)^2*Kb_B_ss^2;
you did not set r_ss when rd_ss is computed. Similarly, Rb_ss is the computation of rb_ss is not defined.

Thank you so much!!!

but I still have a question, I have defined “pai_ss” in calibrated parameters part, I let pai_ss equal 1.008. Why it says pai_ss has no value?

Appreciate your help!!! : )

Please post the updated file.

thank you very much!

Just sequentially execute the parameter definitions in Matlab using F9. Now Kb_B_ss is not defined in

Rb_ss=r_ss+eta_ss-ka_kb*(Kb_B_ss-vb)^2*Kb_B_ss^2;

ok, I will try in Matlab right now . Thank you !: )
