The Emergence of the Child Quantity-Quality Tradeoff - insights from early modern academics

We examine the relationship between family size and human capital among academics in Northern Europe over the two centuries prior to the Industrial Revolution. To measure scholars' human capital, we develop a novel and consistent approach based on their publications. We find that scholars with a high number of publications shifted from having more siblings to having fewer than others during the first half of the 18th century. This shift is consistent with an evolutionary growth model in which the initial Malthusian constraint leads the high human capital families to reproduce more, before being endogenously substituted by a Beckerian constraint with a child quality-quantity tradeoff. Our results support a reinterpretation of the Galor and Moav (2002)'s approach, in which the decline of Malthusian constraints is linked to human capital accumulation during the 18th century.
