st: mutiple treatment / mutiple selection

["Maertens, Miet" <Miet.Maertens@econ.kuleuven.be>]

Can I include double (or multiple) treatments in a treatment-effects
model? Can I include double (or multiple) selections in a selection
model? 

I want to estimate the effect of two different contract options in an
income equation. The two contract options are not mutually exclusive (it
is possible to have none, one of the two or both) and there is
self-selectivity bias with the options. How can include this double
treatment into a regression model?
