Dementia has a devastating impact on affected families' finances. Beginning about six years prior to clinically recognizable dementia, affected families net worth starts to crater. We should treat dementia risk not just as a medical issue, but as a predictable financial shock.

I realised I follow several journals and now I learn about new publications and interesting papers often here first - so I made a Starter Pack with journal accounts in case you wanted to as well. Let me know if I missed an important journal and I'll add it. go.bsky.app/L57tAru

A peer-reviewed study in Biological Conservation reports that China’s 2018 ivory trade ban led to a roughly 50% fall in elephant poaching and a steep drop in ivory seizures. Researchers found no “last-minute rush” before the ban, suggesting consumer demand collapsed buff.ly/2KI1tC1 #ShareGoodNewsToo

It's not innovation per se (on which the US is very good), but its dissemination through the economy and society that determines the success of nations. Europe take note. A good essay by Angela Zhang on the Chinese angle on this. www.project-syndicate.org/commentary/c...

A headline to sum up our times:

"Painfully accurate"

Even after two world wars and a century of upheaval, wealth in 🇩🇪 shows strong persistence. About 8% of today’s top fortunes trace back to the early 1900s: 82 of the richest families today were already among the richest in 1913, challenging the idea of a fully meritocratic elite.

Using voice AI agent to give oral exams to avoid the use of AI is just peak irony.

Tariffs are not fuelling a US manufacturing revival • Manufacturing sector created jobs for last time in March this year, ahead of Liberation Day • Since Trump's tariff salvoes, manufacturing firms slashed headcounts in each month, by around 70k people in total www.ft.com/content/17a1...

Excellent postdoctoral opportunity! Come join us in beautiful Konstanz!

Carol of the Bells in # Kyiv subway. Voices of the Embassies of Germany, France, and the United Kingdom came together to perform Shchedryk in the Kyiv metro as a sign of solidarity with Ukraine. Thankful to everyone who stands with us!

At this holiday season, we should remember people in Ukraine and their fight for freedom. I am proud to support @razomforukraine.org and the Kyiv School of Economics, which is helping to build a brighter future in Ukraine. foundation.kse.ua/en/

Technological progress comes with social costs. A new paper by Stefan Thurner et al. shows that "polarization started to increase exactly with the advent of smartphones and social media." www.pnas.org/doi/10.1073/...

BREAKING: The EU chooses complexity over clarity. Clinging to combustion engines won't make European carmakers great again. Today’s proposal from the European Commission will extend the sales of cars with engines & divert investment from EVs, while China races further ahead of Europe’s carmakers. 🧵

1/ Hope this thread helps break through the mental logjam for normies. For anyone in the game of technology/ innovation/development this is just basic facts now. For the first time in 2 centuries, the West is no longer the leader in future technology,but the follower www.nytimes.com/interactive/...

1/12 China’s favorite US president: Trump is extremely soft on China. The idea that he’s a China hawk is one of the biggest misconceptions. He’s almost as soft on Beijing as he is on Moscow. Both back him for that reason. Here are a few key examples👇

If we add the rest of the EU, then we have an economy with 450 million inhabitants, significantly larger than the US In that bigger economy, productivity is slightly lower than in the US, because of relatively low productivity in Eastern Europe

Ouch. Brutal reality hitting slow EU rare earth policy rollout: Commissioner Sejourne tells NRC: “I was due to travel to Brazil to hold talks about a mine extracting rare earths. 3 days before, we were told that the Americans had come by and bought up all production through to 2030.”

Sehr geehrte demokratische Abgeordnete des Deutschen Bundestags, der einzige Grund, warum die Plattform X in Deutschland noch Relevanz hat, ist Ihre Anwesenheit dort. Ohne Amts- und Mandatsträger wird die Plattform auch für Journalisten irrelevant und mit ihnen für die gesamte politische Blase.

In a rare case of admitting that the Russian invasion of Ukraine in 2022 was based on wrong data, Russian colonel general Chirkin commented as follows: „There was an underestimation of the enemy and overestimation of their troops. Everyone began to say that the war would end in three days.

A simple but solid econ perspective: try to predict worldwide supply and demand in 10 years. Combustion engines will stand no chance against EVs. Makes you realize how useless and backward looking the German discussion of EU policies is.

PM Carney: “Do the Trump” 😅

💻 Laptops are great, but not during class. 💻 Laptops are the standard in classrooms. This needs to change. New meta-analysis of 24 experiments shows that handwriting will lead to higher grades for students. So this 2017 NYTimes op-ed by @dynarski.bsky.social is even truer today.

In light of record submission rates and a large volume of AI-generated slop, SocArXiv recently implemented a policy requiring ORCIDs linked in the OSF profile of submitting authors, and narrowing our focus to social science subjects. Today we are taking two more steps: /1

When Tony Blair came to power in 1997, the UK economy was bigger than China and India combined.

Rarely do German economists agree across various party and ideological lines. On Merz' pension reform (more money for the old, basically) they do.

This is terrifying. "[AI agents] can... infer a researcher's latent hypotheses and produce data that artificially confirms them." ... "We can no longer trust that survey responses are coming from real people" [email protected]

Good Morning Zurich
