**Dear All,  
In my log-linearized medium size DSGE model, I receive the following error messages:**

There are 23 eigenvalue(s) larger than 1 in modulus  
for 17 forward-looking variable(s)

The rank conditions ISN’T verified!

Error using print\_info (line 39)  
Blanchard Kahn conditions are not satisfied: no stable equilibrium

Error in stoch\_simul (line 71)  
print\_info(info, options\_.noprint);

Error in deneme\_stoch (line 580)  
info = stoch\_simul(var\_list\_);

Error in dynare (line 120)  
evalin(‘base’,fname) ;

**\>\> model\_diagnostics(M\_,options\_,oo\_)**  
The following endogenous variables aren’t present at the current period in the model:  
KN  
KD  
model\_diagnostic: the Jacobian of the static model is singular  
there is 1 colinear relationships between the variables and the equations  
Colinear variables:

YD

Colinear equations

\*\*As Blanchard Kahn conditions are not satisfied, I guess the problem is about the values of the parameters (I have checked each equation and log-linearization process several times).  
Any advice to handle the problem is appreciated!

Thanks,\*\*

It’s not about the parameters but about your timing. As model\_diagnostics says:

`The following endogenous variables aren't present at the current period in the model:
KN 
KD 
`  
For at least those two variables, there is a timing problem. If the K stands for capital, take a look at Dynare’s timing convention for predetermined variables in the manual.
