Endogenous variables problem

General DSGE Modeling
1

Hi all,
by preprocessing DSGE-MODEL, this problem met.
however, equation in my research is not wrong and correctly setting.
In fact, similar model under other paper says it can processed.

So that, what matter prevent processing my model?
file is under.
jpdat.mod (19.9 KB) jpmodel.mod (9.1 KB)

 Using 64-bit preprocessor
Starting Dynare (version 4.6.2).
Calling Dynare with arguments: none
Starting preprocessing of the model file ...
Substitution of endo lags >= 2: added 2 auxiliary variables and equations.
ERROR: There are 53 equations but 52 endogenous variables!

error: Dynare: preprocessing failed
error: called from
    dynare at line 282 column 5

As the message says: you have more equations than variables, i.e. your system is over-determined.

Thank you four your response.
I checked my equation, I noticed the error concerned as “u” variables.
This “u” is capital utilization rate and it is making by follow equations.

//capital utilization
u = mu*(rk-q);

This u is estimated as 1 in maximum. so that this is not parameter but endogenous variables.

thank you.
