With a model that size it is impossible to tell. I can only give you the generic advice:

> [@Production negatively react to technology shock](https://forum.dynare.org/t/production-negatively-react-to-technology-shock/20981/4):
>
> You should try to shut of features of the model to see where this comes from. For example, you have a complicated Taylor rule and capital adjustment costs that can be simplified.
