Perhaps you can try Tobit model (with censored/truncated data). Thus you can address the problem at the same time.

Subject: st: Multiple imputation and selection model
Hi,
I am working on a dataset with 2 problems:
- missing observations for some countries that I assume are missing at random, and for which I use multiple imputation
- some countries are not in the sample because no data are available, and this is not missing at random but rather linked to the level of institutional capacity/ development. I could use a Heckman selection model to control for this problem.
Ideally, I would be able to address both problems at the same time - is it possible? Or should I solve the problems separately?
Thanks a lot for your help!
