The fertility wars

The political flurry in the US over the virtues of parenthood and a high birth rate is part of a much larger cultural moment in which the debate on the significance of falling global fertility is pitting two increasingly militant and unyielding sides against each other. We have trade wars, culture wars, even actual wars; we can now add fertility wars to the list. When Elon Musk, a US entrepreneur and businessman, calls Ms. Harris an “extinctionist”, because she has linked the reluctance of young people to have children to “climate anxiety”, he means it, just as he means it when he concludes that “the natural extension of her philosophy would be a de facto holocaust for all of humanity!”

How to get handle on this? With difficulty, but in the end, hopefully with precision and clarity. First, I will briefly show that the fertility wars have been fought for a long time. I will then draw the contours of three separate positions in the fertility wars today—on the Conservative right, on the left, and a feminist perspective—before offering a suggestion on where this discourse goes next, and where it ultimately ends up, if we are sufficiently unlucky or un-attentive.

Things to think about #4

The Economist’s Free Exchange column drops in on the question of an economic motherhood penalty from childbirth. It is nice to see that the Economist correctly distinguishes between two distinct economic motherhood penalties, both of which can be traced to the interplay between evolutionary forces and modernity, where the latter in this case is defined as an environment with rapidly increasing returns to investment in human capital and education. The first, between fathers and mothers, emerge because the cost of child-rearing especially in the early part of a child’s life overwhelmingly falls on the mother, a conclusion which follows from Trivers (1972). This is true in terms of the cost during pregnancy and immediately after too. It is also true before we consider the possibility that the resource allocation trade-off for many women shifts in the wake of motherhood. The second motherhood penalty occurs between women. Put simply, in an economic structure where childless women have the ability to devote all their resources to somatic investment and take advantage of the above-mentioned increasing returns to human capital investment, the wage and wealth divergence between women who have many children and those who have none will widen significantly, at least in theory. For more on this, I cover the theory in more detail in my essay on fertility and sexual selection; see here.

The BOJ & JPY and some new predictions on global fertility

I have a few things on my mind this week. We have to talk about Japan and the BOJ. Last week’s decision by the BOJ to raise its deposit rate above zero for the first time in 17 years cements Japan and its central bank as a counter cyclical indicator, of sorts. While major central banks have spent the majority of the past 18 months raising interest rates, the BOJ has stubbornly resisted calls to exit NIRP, despite rising inflation. Now that the ECB, BOE and Fed are on the cusp of lowering interest rates, the BOJ is pulling the trigger on a hike. The BOJ’s decision raises a number of fundamental questions for global macro traders and thinkers. The most obvious one is whether the twin inflation shock from Covid and shifting geopolitics is now pulling major developed rate markets out of their ZIRP/NIRP funk. And if they are, does this mean that the idea of long-term gravity of rapidly ageing population weighing on inflation and interest rates is wrong? Is Japanification now reversing? I am sceptical, but if Japan manages to escape, it would go a long way to falsify the idea of a determinist link between ageing and disinflation.
