Core EU has 290 million inhabitants: it's a bit smaller than the US (340m) but not much so
The key fact is that productivity in this core EU is essentially the same as in the US:

Adjusted for the difference in price level, GDP per capita has grown 70% in the US since 1990 vs. 63% in the EU27
This corresponds to an annual growth rate of 1.6% in the US vs. 1.5% in the EU.
The US has been doing better post-Covid, but over the medium run no big divergence

So today on the train I chatted with a PhD student in microbiology. She said “I do not know how people used to do research w/o AI!” And she did use it a lot! Sparring, asking questions, testing hypotheses.
In the meantime I was busy bringing a modicum of order to AI code slop by a junior colleague

That perfectly shows all the great stuff of the Danish home financing market I mentioned in the other thread @p-hunermund.com
1) 4% = very high rate here
2) you are not locked-in bc you can redeem the mortgage by repurchasing the bonds - cashing in the present value diff in future payment streams

The @nytimes.com manages to turn folks lucky enough to buy houses with very low (4% in this case) mortgages seem like victims. Huh?

Longer maturities for mortgages are back in the news.
I wrote a Substack post about the benefits of longer maturities, potential concerns of households making mistakes, and what longer maturity mortgages might do for young households and first-time buyers (not much?)

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.

Fun fact. If you are comparing means between two groups in an experiment you can present it as
“Results from a single layer neural network with a linear activation function trained on the dichotomous experimental partition”
“Results from a single layer neural network with a linear activation function trained on the dichotomous experimental partition”
ok so i bought some consumer data and decided i'd test this single layer neural network with a linear activation function from the image below. after testing it against other algorithms i found that this estimator thing had the lowest variance of any linear unbiased training algorithm??
