I don’t think I understand your point. Maybe watch the video again. You can not estimate consumption, labor, and investment. Check the `estimated_params;`

block (in the dynare implementation part of the video)…something like below. In the video, he explicitly states that he estimates “the structural parameters and standard errors of the shock”. That is `RHOA`

(autocorrelation coefficient of shock) and `stderr u_a`

(standard deviations) of the shock…

```
estimated_params;
%parameter, initial value, lower bound, upper bound, unifrom_pdf,,,,, tr
DELTA, 0.025, 0, 1, uniform_pdf,,,,, 1;
BETTA, 0.984, 0, 1, uniform_pdf,,,,, 1;
RHOA, 0.979, 0, 1, uniform_pdf,,,,, 1;
STDA, 0.0072, 0, 1, uniform_pdf,,,,, 1;
stderr u_a, 0.01, 0, 10, uniform_pdf,,,,, 1;
end;
```

Btw, I think your terminologies may be wrong here. In any model, whether RBC/DSGE or linear regression, we have endogenous variables, exogenous variables and parameters, not exogenous parameters and endogenous parameters.
