Germany's Die Linke won last month's Berlin election on a pledge to socialize ~220k flats owned by large landlords. A thread on why housing expropriation is a successful campaign promise, how Berlin's flats became an asset class, and what expropriation would do. 🧵

🚨New preprint! We mapped sibling similarity in education across 28 European countries from 1945 to 1992, finding massive cross-national variation but mostly stability over time. We found NO robust evidence for the GGC within countries across cohorts. 👇https://osf.io/preprints/socarxiv/qayk9_v1

🔍 How does economic inequality impact beliefs in meritocracy? Using comprehensive survey data from 39 advanced capitalist democracies over more than three decades, Markus Gangl & I examine how rising economic inequality has been shaping citizens' belief in meritocracy. 🔗 doi.org/10.1093/ser/mwag016

⏳ Excited to share my new piece, published in @millennjournal.bsky.social! I explore how imagined futures of emergent and disruptive tech loop back to shape present-day politics of war - and how the early history of military ballooning (1783-1907) shows us this recursive logic at work.

Culture shapes #FamilyInvestment choices. @collinsmatthew.bsky.social found that having a brother reduces #Education for first-born boys by 0.05 SD in cultures where sons don’t inherit from their fathers. When sons can’t inherit, parents compensate with more education. doi.org/10.3368/jhr....

Sibling Gender, Inheritance Customs and Educational Attainment
Matthew Collins
This study identifies the causal effect of second-born gender on the education of first-born children and how it varies across traditional inheritance customs in 27 sub-Saharan African countries. When customs dictate that sons do not inherit from fathers, having a brother causes a 0.05 SD reduction in education. For boys who inherit, having a brother reduces inheritance, for which parents substitute greater educational investments. For first-born girls whose brother can inherit, having a brother causes a 0.028 SD reduction in education. Exploiting national legal reforms, I show that sibling gender effects converge when all children can inherit from their parents.
