Good practices include gender-specific compensatory measures such as continuing pension contributions during maternity and childcare leaves, unisex calculation of benefits, equalizing mandatory retirement age and mandatory joint annuities. All these measures, with quite wide margins of difference in the extent of their generosity and with some caveats as to the categories of women who do not benefit from each of these measures, have some marginal impact in reducing the pension gap. Of these gender-specific measures, the only one that almost closes the gender pension gap is mandatory joint annuities. This suggests that the way to rectify women's relative poverty in old age is through mandating joint annuities with their husbands. However, this does not solve the problem for single or divorced women. Furthermore, it leaves the problem of engineering a system that is equitable for traditional dependent marriages and yet can still incentivize economically independent women.
