Blanchard Kahn conditions are not satisfied: indeterminacy

Postby yshguo » Sat Dec 21, 2013 3:19 am

hello, everybody

I encounter this problem: "Blanchard Kahn conditions are not satisfied: indeterminacy " when I simulate a DSGE model. That would be fine if anybody can solve it, thank you very very much! I come from China, my english is not quite well, so I can't write a lot. my email address is yshguo@gdufs.edu.cn.

Best wishes

the questuions are as follow:

Configuring Dynare ...
[mex] Generalized QZ.
[mex] Sylvester equation solution.
[mex] Kronecker products.
[mex] Sparse kronecker products.
[mex] Local state space iteration (second order).
[mex] Bytecode evaluation.
[mex] k-order perturbation solver.
[mex] k-order solution simulation.
[mex] Quasi Monte-Carlo sequence (Sobol).
[mex] Markov Switching SBVAR.

Starting Dynare (version 4.3.3).

model_diagnostics says:
model_diagnostic: the Jacobian of the static model is singular
there is 1 colinear relationships between the variables and the equations
Colinear variables:
c
ch
cf
p
m
l
w
lamda
ii
tao
k
r
rk
d
n
Colinear equations
16 17 23

The presence of a singularity problem typically indicates that there is one
redundant equation entered in the model block, while another non-redundant equation
is missing. The problem often derives from Walras Law.

hello, jpfeifer

thanks a lot for your response, your reply is very useful for me, I have modified some equations, now the problem has resolved.
