Dear Johannes

You can use function selection() of the sampleSelection package and
estimate an endogenous switching regression ("tobit-5") model, where
you have the selection equation to model investmentment vs.
non-investment and you have two outcome equations, one for firms that
invest and the other for firms that do not invest.

Best regards,
