[133] Heterofriendly: The Intuition for Why You Always Need Robust Standard Errors - Data Colada When I taught my first PhD-level methods course, I invited students to submit questions about any topic in statistics or methodology. Six out of 10 students asked about the same topic: robust & cluste...

Thanks for the initiative! The AWI Lab in Heidelberg will support this.

Das wäre wie, wenn meine Autowerkstatt 100€ für die Reparatur will und ich es selbst für 5€ machen kann. Dann ist die Differenz auch keine Subvention.

"Der private Wert von Solarstrom beträgt also 30 Cent pro KWh. Der volkswirtschaftlich wahre Wert des Stroms bemisst sich dagegen am Marktwert, also dem Wert des Solarstroms an der Börse. Dieser beträgt aktuell weniger als 5C pro KWh. Die Differenz von 25C pro KWh sind versteckte Subventionen."

Vielen Dank für den Link. Aber da Hirth nutzt eine ziemlich ungewöhnliche Definition von Subventionen.

Exclusive: Unrest at Wiley journal whose EIC is cited in more than half of its papers Timothy Lee (center) of Macau University of Science and Technology was named editor-in-chief of the International Journal of Tourism Research in 2023. On Feb. 18, a researcher in Italy sent a disgr…

“Maybe, I would have been treated better if I had cited some of the editor in chief’s papers,” Bimonte, of the University of Siena, wrote in boldface in the email, which we have seen. Two days later, an unhappy editor at the journal quit, Retraction Watch has learned.

Bots have made their way to Prolific experiments. Our lab has stopped online testing of adults entirely now for this reason - we want to know if what we study is real. Probably data collected 2-3 years ago are ok, but moving forward we just can't know. www.pnas.org/doi/10.1073/...

Many small delays that add up. But we can improve: here is an example from Magdeburg where they are completely transparent about the timing of all steps.

Fucking love this guy.

This is such a strong comment, published in 2022. It has 14 Google Scholar citations. The replicated paper has 65 citations in 2025 alone - and counting. www.aeaweb.org/articles?id=...

Price controls cause chaos Price controls are worse than you think

I'm super excited for my new paper with Alex Tabarrok
and Mark Whitmeyer.

tl;dr: price controls cause chaos. That chaos causes misallocation. We develop new tools to measure that misallocation, which is 1-9 the size of the Harberger triangle www.economicforces.xyz/p/price-cont...

A few years ago, I was on a commission here in the Max Planck Society that tried to motivate the society to stop wasting millions of Euros on Microsoft licenses for bad calendar and email software. That and Elsevier subscriptions are just wasteful use of public funds imo. >

Not sure but wouldn't these price controls protect (uninformed) consumers in many cases?

The Bundeskartellamt decided yesterday that Amazon cannot remove prices of third party sellers on their platform if these prices - check notes - are too high.

Wiley: "We’re supporting responsible research assessment practices" onlinelibrary.wiley.com/journal/1520...

Also Wiley: "Prove that your article is a good fit for this journal 😉😉😉😉😉 by citing at least two of our articles in your manuscript before we will even consider reviewing it" 🤡

Haha, I thought exactly the same when seeing this paper. It's a 1 in 6 chance, though.

Statement from Bill Clinton

And for payments between consumers we have the same problem as with messenger apps. Multi-homing is possible but inconvenient.

Given that Wero has much lower fees, it should be a dominant strategy for dealers to offer is as an additional payment option. However, for consumers who do not benefit from the lower fees it is all about convenience. I switched from PayPal to ApplePay because it requires two clicks less.

Platform competition (e.g. Rochet/Tirole, 2003, JEEA)

Commitments for public goods provision (e.g. Bagnoli/Lipman, 1989, RES, Oechssler et al, 2022, JET)

Ethical consumers (e.g. Hainmueller et al, 2015, REStat, Kaufmann et al, 2024, QJE)

But I'm not aware of a study of their combination.

Tried to read the Handelsblatt article, hit a paywall, and guess what...

Let us all stand with Chairman Powell.

Interesting perspective on gambling laws. And thanks mentioning our paper!

Video taken by bystander Caitlin Callenson shows an ICE officer fatally shooting a driver in Minneapolis on Jan. 7, 2026. ICE officer fatally shoots driver in Minneapolis

This is a video of federal immigration officers murdering a woman who was not attacking them. In Minneapolis, today.

The United States Constitution protects all people in the United States, Conservative and Liberal. Its suspension will eventually harm all people, Conservative and Liberal.

Marco Rubio is reportedly saying Maduro will stand trial in US courts.

Which means it’s now the US administration’s position that US courts can hold foreign presidents, but not the US president, accountable for crimes.

Point of no returns: researchers are crossing a threshold in the fight for funding With so little money to go round, the costs of competing for grants can exceed what the grants are worth. When that happens, nobody wins.

This report in Nature on the costs of competing for & administering scientific grants is shocking: "In other words, European taxpayers will have spent more on the funding process than on the funding itself, and the scientific ecosystem has been drained." www.nature.com/articles/d41... 🧪

Nice job at Hochschule Heilbronn

Senator Kelly is correct.

Plus a Public Service Announcement:

KEY section of Department of Defense's Law of War Manual is 18.3.2.1.

The VERY rule on the "requirement" to refuse illegal orders gives as its paradigmatic example of what is "clearly illegal:
"orders to fire upon the shipwrecked."
