See They Want More Babies: Now They Have Friends in the White House by Lydia DePillis of The NY Times. Excerpts: “In designing policy requests for federal legislators, however, pronatalists run into a problem: There’s little evidence that subsidies and protections have substantially raised the number of children women have over their lifetime.

How can I not link to a new Sam Peltzman piece on such a topic? Here goes: Since 1972, the General Social Survey has periodically asked whether people are happy with Yes, Maybe or No type answers. Here I use a net “happiness” measure, which is percentage Yes less percentage No with Maybe treated as […]

Over the past half-century, the share of men enrolled in college has steadily declined relative to women. Today, 1.6 million more women than men attend four-year colleges in the U.S. This trend has not lowered marriage rates for college women, a substantial share of whom have historically married economically stable men without college degrees. Both […]

It’s well-known that when a couple has a child, the average woman experiences a “child penalty” in labor market outcomes, while outcomes for the man are largely unchanged. For a discussion of this pattern using US data, here’s an article by Jane Waldfogel from back in 1998 in the Journal of Economic Perspectives. As that…

By Claudia Goldin. From NPR’s Planet Money.”Countries around the world have seen a jaw-dropping decline in fertility rates. In this paper, Claudia Goldin, the 2023 winner of the Nobel Prize in economic sciences, offers a new theory to help explain why (listen to The Indicator’s conversation with her back in 2021). Goldin starts by providing…

What does society expect from fathers?

We live in a society utterly confused about parenthood and the role of fathers. The last Labour government made fathers increasingly irrelevant. In 2020 a law change repealing section 70a of the Social Security Act meant mothers applying for a sole parent benefit no longer had to name the father of their child for the…

Six months ago, I’m not sure that I’d ever heard of demographer Lyman Stone. Now, people in my circles randomly drop his name on a weekly basis. His favorite topic, in case you haven’t heard, is global fertility decline. As a longtime natalist, I share his concerns. One of Stone’s top takeaways: Instead of talking…

Bryan Caplan will feel vindicated: This paper asks whether universal pre-kindergarten (UPK) raises parents’ earnings and how much these earnings effects matter for evaluating the economic returns to UPK programs. Using a randomized lottery design, we estimate the effects of enrolling in a full-day UPK program in New Haven, Connecticut on parents’ labor market outcomes […]

Earlier this week, I was interviewed by Paul Brennan on Reality Check Radio, on New Zealand’s declining birth rate. You can listen to the interview here. We didn’t have time to go through all of the questions I was given beforehand, so I thought I would add some points here, along with some links to…

I’m in China this week, teaching about fiscal policy, convergence theory, and inequality at Northeastern University in Shenyang. So it’s a good opportunity to write about some pluses and minuses of Chinese economic policy. We’ll start this series by looking at demographics, which almost surely is the biggest long-run challenge for Chinese policymakers. How big […]
