"A study... showed that last season’s 2024–2025 mRNA COVID vaccines reduced people’s risk of emergency department visits by 29 percent, their risk of hospitalizations by 39 percent and their risk of death by 64 percent. ”" www.scientificamerican.com/article/new-...

It’s rare, but not unheard of, for non-monarchs to put their faces on coins.

Forskerforum has written a piece about my unfortunate experience with the Danish Office for Naturalization (in Danish) dm.dk/forskerforum...

More volatility and uncertainty from the White House. An abrupt rule change for H1B visa holders. This is not in 🇺🇸 interest.

A surprising result. Let X = Harasheh et al. (2023,Table 1) Y = Ha (2023, Table 1) Z = Table in image Then X - Y = Z.

I added comments on additional papers on @pubpeer.com and wrote up a LinkedIn article. #EconSky #ResearchIntegrity #Economics #Finance #PaperMills @datacolada.bsky.social @retractionwatch.com @elisabethbik.bsky.social www.linkedin.com/posts/peter-...

I recently wrote my first comments on @pubpeer.com Two papers—different assets & sample periods—appear to use the same figure. How did one plot end up representing different variables? #EconSky #OpenScience @elisabethbik.bsky.social @datacolada.bsky.social

🏆 Research integrity consultant and image forensics expert @elisabethbik.bsky.social has uncovered fraudulent data in over 7,600 scientific papers and exposed the practices of ‘paper mills’ that produce counterfeit scientific articles. She is honoured with the €200K Individual Award. Congrats!

Hi @pubpeer.com Have written many comments and have many yet to address. I believe I follow guidelines, but some posts end up as: "comment moderated by admin (For further information, please consult our commenting guidelines)". But I cannot figure out why. Can anyone help? Below is an example.

After the break, we will continue with the next session: "Authorship and Integrity Issues", introduced and moderated by Lex Bouter @lexbouter.bsky.social‬ The first speaker (program change) is Tim Kersjes with 'Paper Mill Use of Fake Personas to Manipulate the Peer Review Process' #PRC10

Give the man a break. At 73, a few minutes of blissful peak performance is impressive. #UNC If you don’t know better — it’s $10M well spent.

We have discovered a new way to compute moments of a random variable with a moment-generating function (MGF). All sorts of moments. #Statistics #Probability #Econometrics

Faculty experience—or even a PhD—is not essential for every university leader, despite research and education being what we do. However, when no one in university leadership has it, this can be the outcome 👇 @UNC www.theassemblync.com/education/hi...

The new Prius is likely to receive a mixed reception.

Vingegaard præstation i dag var “the best long climbing performance ever” på trods af Pogacar var 2 sek. hurtigere. 6.52 ᵉW/Kg for 54:32 min. lanternerouge.com/2025/07/22/h...

44:56 Pogacar 44:58 Vingegaard Slog de lige Pantani's rekord med over et minut? #TdF

#SlavaUkraine fra Dix Park, Raleigh, NC.

Ser kommentarer som ser dette som tegn på doping, og jeg undrede mig også sidste år, hvor Vingegaard og Pogacar begge havde præstationer på Armstrong/Riss niveau. Men der har været forbedringer af grej og hypoxic training som delvist (og lovligt) giver samme effect som EPO. #LivingHighTrainingLow

Pogačar's tid var imponerende. Ifølge CyclingGraphs var præstationen 6.74 ᵉW/Kg for 35:11 min 🔴 på grafen for Pogačar præstationer frem til TdF 2022, hvor Vingegaard vandt på Hautacam 🟣 6.32 ᵉW/Kg for 36:37 min

Trumps handelskrig er et stort opgør med en den regelbaserede frihandel, der er et vigtigt fundament for en moderne markedsøkonomi som den amerikanske. På tilsvarende vis er uafhængige centralbanker en vigtig del af fundamentet. En utrolig vigtig del, faktisk

Every econ debate about immigration:

If Donald Trump wanted to give Russia a helping hand with their summer offensive, it would look exactly like what we are seeing. That is my point in this video, where I also discuss the air war and give a status on the frontline situation. #Ukraine

Tillis: What do I tell 663,000 people in two years, three years, when President Trump breaks his promise by pushing them off of medicaid because the funding's not there anymore, guys?

Endnu en måned er gået, og Kasper Juul Eriksen sidder stadigvæk indespærret.

Hermed #dagenshelikopter, der handler om noget så spændende som det økonomiske råderum. Gæst er overvismand @cjdalgaard.bsky.social

Nine years ago the godfather of Brexit, Lord Daniel Hannan, predicted life in Brexit Britain in June 2025. Roll the tape… (VO by @gavinesler.bsky.social. Part 2 below👇)

This thread turned out to be very accurate.

Firing ALL of the vaccine experts on the ACIP committee? A very RFK Jr. kind of move, and a disaster for America's health.

Absurd nyt fra 🇺🇸 Medlemmer af vaccineudvalget udvælges på baggrund af deres faglige kvalifikationer og ekspertise, og må ikke have interessekonflikter. En af dem (medforfatter) har bl.a. forsket i balladen om HPV vaccinen i 🇩🇰. #dksund

Starting to look like I might not be able to work at Harvard anymore due to recent funding cuts. If you know of any open statistical consulting positions that support remote work or are NYC-based, please reach out! 😅

New publication: “A Multivariate Realized GARCH Model” in the Journal of Econometrics with Ilya Archakov and Asger Lunde. A new class of multivariate GARCH models that incorporate realized measures -- flexible and scalable. #Econometrics #GARCH #Finance www.sciencedirect.com/science/arti...

www.youtube.com/watch?v=i0q_... A brilliant, thoughtful takedown of RFK Jr. by Dr. Mike Varshavski.

A retraction by Oncotarget, but the journal is taking all the credit for my 2020 findings! "Oncotarget’s Image Forensics analysis identified multiple instances of image manipulations". What a crappy move from Oncotarget. HT: @thatsregrettab1.bsky.social pubpeer.com/publications...

Often reminded of this post….

Harvard's past international students include incubator of Moderna, co-founder of Facebook, at least 11 Nobel Prize winners, and 14 heads of state.

Among current Tesla owners I suspect his favorability rating is also disastrous, and losing brand loyalty will be costly for Tesla. Tesla has long held the top spot in brand loyalty (at about 67% vs 52% average).

Det er virkeligt skørt herovre. Kasper Juul Eriksen fra Aalborg har nu været spærret inde i over en måned. www.mississippifreepress.org/ice-arrests-...

Yeah, it does seem kinda bad for a newspaper owner to get into business with a guy who vivisected one of his opinion columnists.

It’s this time of the year… #UNC Economics Commencement 2025 We have about 450 Econ Majors this year.

Man taler varmt om at styrke 🇩🇰 dansk forskning. Men børn af forskere straffes — fordi de har været med på forskningsophold i udlandet. Absurd ringe svar fra ministeren. Det er 100% #Kafka #dkmedier #dkforsk #dkpol

Tesla would have been a great deal better off had its CEO stayed out of polarizing politics.

If only someone in the White House would have uttered the words: “You don’t have the cards”.

Citation needed.

Der ville være noget at juble over, hvis det var attraktive forhold i Europa🇪🇺 der fik forskerne til at komme. Der er altid 🧑‍🔬 👩‍🔬 som krydser Atlanten — i begge retninger. Den nuværende effekt — hvis den findes — vil være kortvarig. #dkforsk #dkmedier

High-frequency data ruled financial econometrics for 20 years. What is the next frontier? 👇

Some personal news: the Department of Homeland Security has given me, an immigration lawyer born in Newton, Massachusetts, seven days to leave the U.S. Does anyone know if you can get Italian citizenship through great-grandparents?
