Why do people have kids in developed societies? We propose an empirical test of two alternative theories – children as 'consumption' vs. 'investment' good. We use as a natural experiment the Italian pension reforms of the 90s that introduced a clear discontinuity in the treatment across workers. This policy experiment is particularly well suited, since the 'consumption' motive predicts lower future pensions to reduce fertility, while the 'old-age security' to increase it. Our empirical analysis identifies a clear and robust positive effect of less generous future pensions on post-reform fertility. These findings are consistent with 'old-age security' even for contemporary fertility.
