st: endogeneity and count models.
I am estimating a count model and I have an endogeneity problem. However my
endogenous varaibles are not dummies but continuous variables. I want to
estimate the impact of trade variables on innovation. The trade variables I
have are limited to multinational firms while the innovation activity is no=
The endogeneity of those variables comes from the fact that more innovative
firms have a higher probability of becoming multinationals.
I know that there is a GMM model that treat endogeneity in count models =
don't think that it is available with STATA. However STATA estiamtes a "FIM=
estimation of an endogenous switching model for count data" where the
endogenous variable needs to be a dummy.
If I include in the "FIML estimation of an endogenous switching model for c=
data" estimation a dummy for multinational firms and treat it as endogenous=
will this be sufficient to controle for the endogeneity of the trade variab=
Thank you for you time and attention.
