Victor:
as per your low R.sq within and most of your predictors showing wide 95% Cis I wonder whether your model is correctly specified.
I would first investigate whether -fe- specification is the right one for your regression model. As you invoked non-default standard errors, -hausman- is out of debate there. You should rely on the glorious community-contributed command -xtoverid- which, in turn, being a bit old-fashioned, does not support -fvvarlist- notation. The usual fix is to prefix your -xtreg- code with -xi:-. If -xi:- does not do the trick, you should calculate interaction by hand (provided it makes sense to keep them).
