We develop an instrumental variable approach that relies on the large increase in benefits for birth cohorts from 1885 through 1916, and the subsequent decline and flattening of real benefits growth due to the Social Securing 'notch', to estimate of Social Security on elderly poverty. Our findings suggest that over all elderly families the elasticity of poverty to benefits is roughly unitary. This suggests that reductions in Social Security benefits would significantly alter the poverty of the elderly UR - https://www.nber.org/papers/w10466 UR - http://dx.doi.org/10.3386/w10466 ER -
