Denmark is best in EU in getting workers back into jobs (twice the average rate). They also do tons of RCTs to find out what works and apply behavior science. Can’t say it’s causal, but it’s an interesting correlation at least.
I 2024 var Danmark bedst i #EU til at få ledige i job. 40,8 pct. af de ledige i et givent kvartal, kom i job i det efterfølgende kvartal, hvilket er væsentligt over EU-gennemsnittet på 24,2 pct. Det er 14. år i træk, at Danmark er EU-mestre i at få ledige i job #dkpol www.ae.dk/analyse/2025...
Danmark er EU-mestre for 14. år i træk: Bedst til at få ledige i job
Gennemsnitligt 40,8 pct. af de ledige i et givent kvartal kom i job i det efterfølgende kvartal i 2024. Det er den højeste andel i EU – for 14. år i træk. Danmark er også bedst til at få langtidsledig...

Oh wow, this is really great work. Recent results on PCGs allowed much more efficient MPC preprocessing (among other things) using somewhat new assumptions. Apparently, these assumptions are too strong.
Congratulations to the authors on their IACR grant slam of breaks :)

The Trump admin communicates on Signal and added a journalist to a war planning chat group.
Despite the obvious trainwreck that this news is (but not surprising), I'd like to thank them all for some extra material I'll teach tomorrow in a course about private communication :)
