# Blanchard Kahn conditions are not satisfied: indeterminacy

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

model_diagnostics says:

[quote]model_diagnostic: the Jacobian of the static model is singular
there is 1 colinear relationships between the variables and the equations

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.
