You'll get results by typing

mi estimate, post : logit employement alder barn

However, I am not sure whether the results mean the same thing as in
normal non-imputed datasets. One problem I can imagine is that average
marginal effects need to be averaged, and I am not sure whether your
marginal effects are averaged over the appropriate sample.

Alternatively you can interpret the odds ratios, which I expect to be
less problematic

mi estimate, or : logit employement alder barn

Hope this helps,
Maarten
