The calculations of researchers show that if the salary levels of men and women differ by 30-40%, under other equal conditions the pension savings of women will amount to 70-77% of men^,s savings. Going on baby-minding leave will reduce the pension savings of women by 7-11%, two children “eat up” 14-21% of the savings and three children – 21-30%.
