Since women on average live longer than men, pension systems that use gender-specific life tables in the calculation of benefits (i.e., one life expectancy estimation for women and another one for men) generate still lower monthly benefits for women. In contrast, the use of unisex life tables generates equal monthly benefits for women and men who have equal pension fund accumulation and retire at the same age. While this involves a subsidy from the average men to the average women, gender-specific life tables, in contrast, privilege the actuarial link between contributions and benefits for each individual and offer higher benefits to men.
