We can’t just compare women with children to those without them because having children is a choice that’s correlated with all of the outcomes we care about. So sorting out two groups of women based on observed fertility will also sort them based on income and education and marital status etc.
Successfully implanting embryos on the first try in IVF is probably not very correlated with these outcomes.
This is maybe a dumb question, but I would have imagined that successful implantation would be related to good health outcomes (based on some intiution that successful implantation represents an organ of your body functioning properly, and imagining that the higher success rates of younger people has to do with their health). Is that not true?
This is what I came to ask about. Randomizing based on health and then finding that the healthier group makes more despite other factors seems like it doesn’t really prove the thing the paper is claiming.
Although the fact that wages matched between the groups beforehand is pretty interesting.
