The Unassuming Economist

From Conversable Economist:

“For some decades now, the world has been following the patterns of a demographic transition with life expectancies rising and birth rates falling, as we head for a world where the elderly are a much larger share of the global population. However, Matthias Doepke, Anne Hannusch, Fabian Kindermann, and Michèle Tertilt argue that it’s time for “The New Economics of Fertility” (IZA Discussion Paper #15224, April 2022). For a short readable overview of the main themes, you can check their shorter discussion at the VoxEU website (June 11, 2022).

From the abstract of the academic paper, the authors write:

In this survey, we argue that the economic analysis of fertility has entered a new era. First-generation models of fertility choice were designed to account for two empirical regularities that, in the past, held both across countries and across families in a given country: a negative relationship between income and fertility, and another negative relationship between women’s labor force participation and fertility. The economics of fertility has entered a new era because these stylized facts no longer universally hold. In high-income countries, the income-fertility relationship has flattened and in some cases reversed, and the cross-country relationship between women’s labor force participation and fertility is now positive.

A couple of pictures may help, here. It used to be that countries with higher incomes had lower fertility rates, but among high-income countries, this pattern no longer holds. Here’s a figure taken from the VoxEU overview. The top panel shows that within the group of high-income countries in 1980, countries with higher per capita GDP had lower fertility, but by 2000, countries in this group with higher per capita income had higher fertility.”
