This paper studies the intracohort redistributive aspects of the United Sta
tes social security system in the context of a computable general equilibri
um model. It determines how the well-being of individuals who differ by gen
der race, and education is affected by government social security policy. D
ifferences in life expectancy and labor productivity translate into differe
nces in capital accumulation and labor supply distortions that are responsi
ble for the observed welfare difference between individuals of the same age
cohort. [JEL: E62, H55, H61, J1].
