Thank you all.
I will try adding more variables to the model, and think on the
economic vs statistical significance of the results (I will look for
the appropiate null hypothesis, as opossed to the default zero).
Regarding the independe of the observations I ran Durbin Watson
(although my data is non time series), and the error term do not seem
to be correlated among observations.
Regards and thanks again,
