With regard to the return to work, the work we have done recently, not yet published, suggests that women are less likely to unretire, having retired. This may be connected with their care and responsibilities, and also with, let us say, a more hostile labour market with regard to their opportunities—especially with regard to things such as starting a new business, where women seem to have lower rates of entry.
So the “return to work” process is taking place, but it seems to be at a lower rate for women than for men.
