ETSC: Mutual recognition deal with U.S. will cost lives on Europe’s roads By signing up to mutual recognition of vehicle standards with the United States, the European Union has waved the white flag on road safety. This is not a technical detail – it is a political choice…

This is an INSANE decision by the E.U.

“By signing up to mutual recognition of vehicle standards with the U.S., the E.U. has waved the white flag on road safety. This is not a technical detail – it is a political choice that puts trade convenience ahead of saving lives.”

This will kill people.

Economic data. Where does it come from, what do we do with it, and why must politics stay out of it? In this episode of "The Professor Is In," economist Justin Wolfers tackles the battle over the jobs numbers—and why trustworthy economic data matters for everyone. 📊 Why do we need…

This week on #TheProfessorIsIn, we dig into official economic statistics. What are they? Why does the government provide them? Why there's a trade-off between accuracy, timeliness, and cost. And why it's so important that these numbers be produced free of political interference. youtu.be/oSbnv2drRkA

"In the end the Party would announce that two and two made five, and you would have to believe it." - Orwell, 1984

I'm genuinely unsure whether this is the best or worst time to be working in official statistics 🤔

So, basically, going forward, we're going to have:
☑️ fake economic numbers
☑️ fake census numbers
☑️ fake public health numbers
☑️ no education numbers at all

Trump Gets Rid of Those Pesky Statistics The numbers were simply not patriotic enough.

Donald Trump Declares Victory Over Statistics

I was just informed that our Country’s “Jobs Numbers” are being produced by a Biden Appointee, Dr. Erika McEntarfer, the Commissioner of Labor Statistics, who faked the Jobs Numbers before the Election to try and boost Kamala’s chances of Victory. This is the same Bureau of Labor Statistics that overstated the Jobs Growth in March 2024 by approximately 818,000 and, then again, right before the 2024 Presidential Election, in August and September, by 112,000. These were Records — No one can be that wrong? We need accurate Jobs Numbers. I have directed my Team to fire this Biden Political Appointee, IMMEDIATELY. She will be replaced with someone much more competent and qualified. Important numbers like this must be fair and accurate, they can’t be manipulated for political purposes. McEntarfer said there were only 73,000 Jobs added (a shock!) but, more importantly, that a major mistake was made by them, 258,000 Jobs downward, in the prior two months. Similar things happened in the first part of the year, always to the negative. The Economy is BOOMING under “TRUMP” despite a Fed that also plays games, this time with Interest Rates, where they lowered them twice, and substantially, just before the Presidential Election, I assume in the hopes of getting “Kamala” elected – How did that work out? Jerome “Too Late” Powell should also be put “out to pasture.” Thank you for your attention to this matter!

Unquestionably the most dangerous and corrupt attack on the independence of US economic data in American history. Trump is firing the head of the BLS, a longtime civil servant confirmed 86-8 by the Senate, simply because the job numbers came in below his expectations today

People have no idea how valuable it is to have accurate statistics on the state of the economy and society. And yet, here we are as Trump turns to another page in the autocrat's playbook.

Trump is ticking every box in the authoritarian playbook: firing the heads of statistical agencies that publish numbers he doesn’t like. U.S. data can no longer be trusted — and the world’s trust in America is gone for good.

US economic data quality a worry, authorities not acting urgently enough, experts say Risks to the quality of official U.S. economic data - long seen as the gold standard - are worrying 89 of 100 top policy experts polled by Reuters, with most also concerned that the authorities are not addressing the issue urgently enough.

"People take statistical agencies for granted. So they're easy to cut because there's no lobby or special interest group that's powerful enough to protect them."
- Ethan Harris, former head of global economic research at Bank of America

Super ouvrage, je suis très content de lire qu'il continue à évoluer 👏 Est-ce que l'édition anglaise sera également mise à jour ? 😇

The Theory of Economic Complexity Economic complexity estimates rely on eigenvectors derived from matrices of specialization to explain differences in economic growth, inequality, and sustainability. Yet, despite their widespread use,...

Same here! 👋 My Twitter/X content has become deeply boring, whilst I cannot spend 5min here without reading something interesting 🥰 I plan to use the "Sky Follower Bridge" one last time this week and then I am gone 😊
