"[S]ome countries often characterized as low-mobility emerge as matching or surpassing the egalitarian Nordic countries, reinforcing the view that wider mobility differences cannot be attributed solely to the education system." This month in our journal, @sociologicalsci.bsky.social

Damning overview of the nudging literature. "[We] provide the most comprehensive synthesis of the effectiveness of nudging." "We find a small aggregated effect size." "[Our results show] the urgent need for higher quality, preregistered meta-analyses to clarify the true impact [of nudging]."

In an interesting turn of events, US and Danish government came up with the same to help with the affordability crisis: longer mortgages! That has sparked some backlash. But in the US, it seems the discussion is focusing on the wrong stuff. Well, let’s try to learn from 🇩🇰.

New WP: We study how minimum wage increases affect poverty and food hardship in the U.S from 1981-2019. Different from recent work, we study the Supplemental Poverty Measure + two measures of food hardship, factor in cost-of-living differences, and more. www.iza.org/publications...

This is a fabulous response by my colleague Kevin Munger to "that" Economist piece about the EUI. Perhaps @spignal.bsky.social and @jhooper.bsky.social might be interested! kevinmunger.substack.com/p/i-guess-th...

[New finding!] Ryohei Mogi, Ryota Mugiyama, & Alyce Raybould (@alyceraybould.bsky.social ) has shown that individuals without a romantic partner are more likely to revise their fertility desires downward.‪ ‬

Want to know why demographers aren't panicking over low birth rates? @lesja.bsky.social, @shelleydclark.bsky.social, & I have a new piece in @theconversation.com explaining the faulty logic that underlies the low birth rate-induced population panic than fuels the pronatalism movement. 1/n

A Nazi owns Twitter, right wing billionaires own the Wall Street Journal and the LA Times, and CBS is run by a right wing nepo baby who just fired one of the network’s biggest stars for criticizing Donald Trump. Here’s why America has a left-wing media bias problem.

🔴New working paper with @marcocozzani.bsky.social and @juhoharkonen.bsky.social. We describe the temporal link between conception timing and preterm birth rates. When conception rates fluctuate, preterm birth proportions shift predictably but with different magnitudes depending on baseline risk. 1/4

Much of that distortion can be traced back to a few hyperactive users -Just 10% of users produce 97% of political tweets -A mere 0.1% of users share 80% of fake news This leads us to believe that society is more polarized, angry, & deluded than it really is. www.theguardian.com/books/2025/j...

My book, "Decline and Prosper!", presents a comprehensive and evidence-based overview of the causes and consequences of global fertility decline. I argue that low fertility is inevitable, yet also has positive effects. We should help people have the children they want bit.ly/35Hm3Yk

As some of you guessed, the two models are statistically indistinguishable. The answer is Model 1, but there was no way to tell from the data. I was very surprised when I first saw this. Here we show that this confounding of heterogeneity and reinforcement is general: www.pnas.org/doi/10.1073/...

“We argue that higher dependency ratios associated with the demographic transition can be considered a manageable challenge for many”

In Nordic welfare states, not all family policies promote equality. A new AJS article by Evertsson, Moberg & van der Vleuten compares earnings penalties in same- and different-sex couples across countries, showing how policy design shapes work–care divisions www.journals.uchicago.edu/doi/10.1086/...

Children from dissolved families benefit 5-7% less from non-school learning environments, with effects increasing over time. Schools showed little ability to compensate, suggesting deteriorating home environments post-separation primarily drive achievement gaps. New article out in ESR

“higher earnings for both men & women increase likelihood of first birth; couples in which both partners are high earners are most likely to have children. The positive income-fertility association remained stable for married couples but grew stronger for single/cohabiting individuals in late 2010s”
