I wonder if the United States can learn anything from the last time a major industrialized country decided to isolate itself from the rest of the world? Almost a decade after the Brexit vote, GDP in the UK is around 6-8% lower relative to peer countries. (Source: www.nber.org/papers/w34459)

Anyone have experiences with a 1040-NR (U.S. nonresident tax return)? How difficult is it (in hours?)?

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. Well, let’s try to learn from 🇩🇰.

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”

as a condition of funding, we were asked to affirm that we wouldn’t undertake any diversity, equity, and inclusion work, whether or not we used the government funds to do so. The PSF simply couldn’t agree to that statement,

In pain and with an arm in a sling, one of the joys of the day comes from @hotgpod.bsky.social. I got it recommended by @p-hunermund.com, and can 100% endorse. A history of which I knew embarrassingly little, narrated very entertainingly by a true expert. Give it a try! The Ottos are unbelievable

Italian Senator left Jeffrey Sachs literally speechless and shocked by calling him a liar and a propagandist. It happened on Prime Time Italian television. Priceless 🤩 [ENG SUB] (The 2nd part in the next tweet)

Tip When I start working on a new project, I run time.now() Once and use the microseconds number as seed

😬 In min/km that’s 2.5km at ~ 5:48, which is ~average running time for a 5k among female participants to the yearly hygge-first DHL relay in DK, to which about 4% of the population participates, and where you run with colleagues among smoking grills and beer stands. dhlstafetten.dk/om-dhl-stafe...

Evidence from random roommate assignment and a gaming ban for minors in China once again show what I now believe incredibly strongly: smartphones and social media destroy civilization via @arpitrage.bsky.social

Linkedin never disappoints. “The social safety net is so good that nobody takes any risks” is a masterpiece. Anyway, 🇩🇰 has also drawbacks.

Random shoutout - I just started to read Data Engineering Design Patterns by @ssp.sh and it is full of tremendous inspiration, not only from a technical perspective, but also on how to effectively communicate data challenges. Getting pumped abt returning to work after paternity leave dedp.online

Fatti non foste a viver come bruti, ma per seguir virtute e canoscenza

It's always the same small circle of people talking to each other at the NBER—while the others quietly watch from the back or from their screens at home. Though I'm sure the institution was founded on noble intentions, nothing better captures the profession's insularity and quiet collusion.

The drones in Copenhagen have been a painful reminder at completing the preparations recommended by the 🇩🇰 government in case of sabotage to critical infra. Last items: water for three days, emergency radio. If you haven’t done it already, it is a good time to do it now!

Sssh, do not break the bubble of the American pundit class, “the Europeans might enjoy decent healthcare, social safety nets and basic human rights, but they are lazy while we work a lot” is all they have left

Well, preparing roe deer stew with the main ingredient grazing just out of the window is a first

I wrote something for The Nation about how Republican style has changed over the last fifty years. But first, let me tell you a short story. 🧵 www.thenation.com/article/soci...

HAPPY INDEPENDENCE DAY, UKRAINE 🇺🇦 34 years ago, we chose us. All of us - East and West, Lviv and Kharkiv, Crimea and Donbas. We chose each other. Not division. We chose unity, identity, and the promise of a shared future. 1/3

I am a fan of the “right tool for the right task” analogy for coding with AI. I also see it as a very powerful tool for three use cases: 1) simple boilerplate functions I code rarely and are always the same. Think “make a decorator for functions that prints the function name + its running time”

I believe we can teach data analysis/ econometrics with Python. From OLS to machine learning and event studies. Scripts for 42 case studies. #pyfixest for regressions. (With Stata and R to compare) Check out the revised Github.com/gabors-data-analysis/da_case_studies

Parenting win: behavioral science defuses sibling device battle Me: whoever uses the device 1st gets 3 minutes less time than whoever uses it 2nd Kid 1 (thinking; loss averse): no, but how about whoever uses it 2nd gets 3 minutes more than whoever uses it 1st? Me: ok Kid 2: deal!

It is a product made by Americans for Americans 🤷‍♂️ Checks out

BREAKING: new study just dropped that shows compelling evidence that cell phone bans cause student grades to modestly increase. Grade increases are largest among low performing students.

In Denmark, new mothers are quasi-randomly assigned to mother groups by nurses. This new paper shows that being assigned to a group with a depressed peer decreases mothers self-reported mental health + increases mental health care uptake. Fascinating!

Enjoying your summer vacations? Here's a Data Engineering #Roadmap that helps you learn the basics to be a data engineer. The schedule is three weeks; it's very ambitious, but you can schedule at your own pace.

Det her IQ-race-nonsens dukker også op på den danske del af X. Det "data" der ligger bagved er ikke kun bras. Det er bevidst udvalgt og behandlet til at give dårligere resultater. Det kan ikke bruges og det siger ikke noget rigtigt om verden. bsky.app/profile/whst...

this reply is complete poster's madness but I was genuinely curious if I could answer this easily (been wanting to try jupyter)

You should never follow any of these color charts. They are all stupid. I'll show you why. 🧵

Europe has replaced the lost US aid to Ukraine in 2025.

Heya #EconSky #DataSky Moving from Stata to duckdb (thx @alemartinello.com for the push) Wrote my 1st substack post about it (and share code). Read for free and please suggest how I can make it faster. Thanks! hanshenriksievertsen.substack.com/p/moving-to-...

Vi finder i dette studie 1) Piger født tidligt på året, og altså relativt ældre i klassen, sjældnere får ADHD medicin end klassekammerater født senere på året 2) Vi finder ingen effekt for drenge 3) Hele effekten på piger er fra piger i lavtindkomstfamilier. www.sciencedirect.com/science/arti...

About 110 Russian drones are already in Ukraine's airspace. Our night begins.

Cool paper providing evidence for something I have often heard as a hypothesis: subtitles as a boost to English skills.

𝐏𝐲𝐅𝐢𝐱𝐞𝐬𝐭 0.30.1 is on 𝐏𝐲𝐏𝐢 and I am extremely happy with this release, mostly because of two 𝐧𝐞𝐰 𝐟𝐞𝐚𝐭𝐮𝐫𝐞𝐬: a Rust back end for all performance critical parts and quantile regression.

Can we take a few minutes together to dig into the economics of immigration? This video is a little longer, but hopefully trades out a bit of heat for a bit more light.

I'll give this a shot. 🧵

Earlier this week, I asked which tie knot you think looks better. Of course, you can wear whichever you like. But here's the social history behind both knots and why some people consider one better than the other. 🧵

The chatbot loves to "Yes, AND..." in the bleakest and stupidest ways imaginable. We NEED to teach people to not trust the bullshit machines. This is going to absolutely ruin some credulous and vulnerable people. I just... no clue what to say here. This made me very sad. For all of us.

Il Big Beautiful Bill che sta per essere approvato in Senato è un concentrato del peggiore trumpismo. Toglie ai poveri per dare ai ricchi, toglie ai bambini per dare agli anziani, taglia l'assistenza sanitaria e l'assistenza sociale ai più vulnerabili, mentre arricchisce ulteriormente l'1%. 1/4
