Hey guys!
I am writing a dynare code following Gertler and Karadi’s paper “A model of unconventional monetary policy”. I want to introduce a credit policy shock but the code cannot run!
The problem is:
"Error: File: GK_creditpolicy2018.m Line: 416 Column: 18
Unexpected MATLAB expression.
Error in dynare (line 223)
evalin(‘base’,fname) ;"
GK_creditpolicy2018.mod (9.8 KB)
I cannot find the errors! Would anyone help me?
I post the code here…
Thank you in advance!
title('Household's consumption')
needs to be
title('Household''s consumption')
to be recognized as a string in Matlab
Thank you professor! Now the error is:
"Error using print_info (line 83)
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 check (line 76)
** print_info(info, 0, options);**
Error in GK_creditpolicy2018 (line 386)
oo_.dr.eigval = check(M_,options_,oo_);
Error in dynare (line 223)
evalin(‘base’,fname) ;"
What is wrong in your opinion? Thanks for the attention!
You need to find out why your changes imply that the steady state cannot be found.
Thank you professor!
Now I changed some equations and I added the initval block!
The error now is:
"Error using print_info (line 37)
The generalized Schur (QZ) decomposition failed. For more information, see the documentation for Lapack function
dgges: info=28, n=26. You can also run model_diagnostics to get more information on what may cause this problem.
Error in check (line 76)
print_info(info, 0, options);
Error in PROVA (line 491)
oo_.dr.eigval = check(M_,options_,oo_);
Error in dynare (line 223)
evalin(‘base’,fname) ; "
What is wrong now? I post, as usually, the code…PROVA.mod (10.7 KB)
model_diagnostics
returns
MODEL_DIAGNOSTICS: The Jacobian of the static model is singular
MODEL_DIAGNOSTICS: there is 1 colinear relationships between the variables and the equations
Colinear variables:
psi
Colinear equations
32 36
The equation
psi = psi+kap*(Rk(+1)-R-SPRSS)+shockpsi;
is strange, because it implies
0 = kap*(Rk(+1)-R-SPRSS)+shockpsi;
i.e. the psi
drops out.
Hi everyone! I’m still working on Gertler and Karadi paper…
Now I’m trying to study this model with EU calibration. Now I have a problem: the residual of equation 21 is not zero and I don’t understand why.
I attach the code here…Could anyone help me?
Thank you in advanceGK18EU.mod (10.2 KB)
gov = 0.215; % government spending over GDP
seems to be inconsistent with
GSS = 0.38; % ... government spending
