Pensions and Fertility: Microeconomic Evidence

This study identifies the causal effect of pension generosity on women’s fertility behavior. It capitalizes on Brazil’s expansion of the pension system to rural workers, whose pension wealth subsequently more than tripled. Difference-in-difference, instrumental variable, and event study methods show that the pension reform reduces the propensity of childbearing of women of fertile age by 8 percent in the short run. Completed fertility declines by 1.3 children within 20 years after the reform, reducing the contribution base of the pay-as-you-go long run. The fertility response is strongest at higher birth parities, among older women, and among mothers with sons. (JEL H55, I38, J13, J16, O15)
