Okay, I can try to comment on that.
I don't think we always have empirical evidence for some of these ideas. Generally we saw a very large increase in the educational levels of women, starting with women who were going to college in the 1960s. They were going to college for the purposes of training for careers, and then that obviously led into their careers.
There is a big generation difference there on how all decisions are being made in the family. For women who were getting married before the 1970s, it was very much taking what their husbands were doing as given, and then maybe joining the labour force, contributing a little bit in terms of income to the household.
Today, though, when you look at how decisions are made by families, we can definitely say that those decisions are made jointly. So a husband and wife are going to sit down together and decide how much each of them is working in the labour market, how much time each of them is spending in the household and on child care, and all of these things, and all of their financial planning would be done jointly as well.
Now, there is some individual aspect to that. To the extent that if a woman spends time out of the labour force for child care, which might just be the choices they make as a family, she's the one who has to take the penalty in the sense that she's lost some labour market experience. She might have given up that raise, given up a job promotion. That happens, and you just take that as part of the package of staying home to take care of your children.
The concern is that if that couple were to get divorced, you couldn't contract how to handle that loss in the labour market. You can try. We do try to account for these things in divorce agreements, at least to some extent, but it's not something we can measure perfectly, so it's not something we can contract perfectly.
To that extent, we don't have perfect contracts for marriage. There is still some individual component to financial planning, and perhaps that's where we see a generation of women now who really independently plan their careers before they even think about getting married and having children. So you might think this really does get built into the individual decision, prior to marriage, before that even starts.
