Closing the gender gap
The latest episode of The Impact podcast discussed parental leave policies in Denmark and Iceland. It appears that the more equality there is in the amount of parental leave given to men and women, the more the gender wage gap closes over time. Men who take more parental leave also tend to end up taking on more of the household and childcare duties long term.
However, the more optional leave is for men, the less likely they are to take it. In part because of the economic disadvantage, due to the current wage gap.
