This is what rapidly accelerating warming looks like. Another off the chart datapoint: NOAA Sea Surface Temperature data for the summer 2025. We will discuss this and more on Climate Chat today. See link for time and hit the 🔔 to get a notification when we go live 1/2 youtube.com/live/BNZ_biC...

Extremely useful article. I would just add that for industrial policy to work we need to think about how to boost the information capacity of governments -- and, in liberal democracies, do so in a way that doesn't infringe on civil liberties. The other big concern is ofc political economy.

Well worth a read

"With poorer "new information" entering the information ecosystem, the quality of the information decreases both because the equilibrium quantity of truthful information declines and because the share of misinformation increases."

Excellent thread -- very thought-provoking!

The greatest fixed point estimation of all ages 😇

This is fun...

So much (economic)? history in one picture...

Interesting and thoughtful thread

A very interesting take

A tale of two moments...

As many jobs simply amount to a database query, framing the impact of AI in this way is easy. We may see that many of these jobs survive, not because of the fact that the database query can now be done cheaply. The constraint may well be (not) knowing what questions to ask.

On high dimensional complexity in reasoning, I am wondering. Do we have measures of high dimensional cognitive complexity? When we "explain" stuff in economics in applied terms, we typically at most consider 2 to 4 variables max.

Reasoning versus storytelling funnels in a statistical world

Kafka Meets Schroedinger -- that would also be a great paper title 😅

If only there was an „onward use“…

Obviously there is a latent point to be made about common law versus civil law based systems...

Going over my "digital assets", websites and projects I have had going for many years, I came across this old one. In 2010/2011, I developed an automated conflict event retrieval pipeline using semantic role labeling for my then job market paper. Constructing structured data...

This case is really interesting and one that illustrates the role that licensed occupations in society. I think it also illustrates some arbitrariness, traces of feudalism and highlights how AI may disrupt legal services. A short journey through this "story" with AI....1/N

In light of development around d immigration and UK policy stance I want to reiterate this. It’s almost the same decadal play…

I always suspected that there is a REASON why the UK pushed ahead with the census right during the pandemic... despite it being done mostly online.

Right hand drive problems (?)

Unless of course it’s full on flight and fight response and we are doomed but I refuse to accept this. We have to talk about informational boundaries

Not sure but I think you could even work out the location of the interference if it were a point source given the structure of the passes (these satellites go around the earth really fast) but maybe that’s for another day and also this is why I fear about 🛰️💥

Artifacts of electronic warfare when studying SAR satellite imagery...

Growth by vintage — and if you zoom out sufficiently far one basically realizes that money also has vintages…

But but but... "it worked". Next up: high dimensional imbalance in presence of high dimensional treatment effect heterogeneity.

Choke points, any guess which one is which? A)

Good...

Not for U! This product labelling is the product of the UK/EU trade deal post Brexit. It also may serve as subtle messaging: not good enough (?) for the EU/single market?

Funny,... this is how AI sees the world when asked to draw a stylized world map of some main countries of focus.

Interesting will we see a Siberian Curry Trade 🧐

The Son shines inside, the sun shines outside.

We have yet to fathom and come to terms with the (accidental) damage that platforms like google scholar etc may have done to the advancement of the human condition.

Soon we will arrive at the conclusion that perceived authority of knowledge or their articulated stories is really what matters. Then we may ask ourselves about the mechanisms of the what, why & how this authority is shaped. Then we are not far from deep encoding of information.

Curious to see when we get more disclosure on UK strategic shift towards bilateralisation post Brexit. The UK is pursuing a similar approach to the US bypassing European institutional pillars. One proxy for measurement: (re)activation of consulates & hiring activity.

The sooner we recognize that much of the labor market in particular in the „high skill“ services domain may better resemble economic care communities the better… AI will create a reckoning that will further amplify already blatantly extreme demographic frictions.

State of UK charging infrastructure...

Another geopolitical hotspot to consider. There is so much going on in the baltic sea as many things are coming together. What you see here at a distance is a ship that is or was part of the Russian shadow fleet. What is going on here? And how will technology change the game...

My approach to research 😬

Guard duty.

And we have another trade shock incoming...

Let me add a reflection on this great paper. The "Kafkaesque" overload of rules isn’t only about political instability (as the work by @grattonecon et al shows). But there may be another important factor: how or if the state can insure itself or its representatives... 1/n

This is great — back a year ago I was sketching/playing with my own solution but this seems clever way to build a lean index…

Methinks… peculiar „line“… hmm 🧐 1/…

One way to interpret this: this intervention was meant to be a lifeline for the high street...

I think I accidentally dumbstruck a bank employee yesterday attempting to cash in an old cheque saying: "A bank is just a spreadsheet."

Trade shock... incoming.
