Und dazu natürlich auch wieder eine (wahrscheinlich) äußerst ineffiziente Kaufprämie für PHEVs 😞 👇🏼 link.springer.com/article/10.1...

Ich finde es ja so peinlich, dass unsere Bundesregierung den Lobby-Sprech von den "hocheffizienten Verbrennern" einfach so übernimmt. Wirklich hocheffizient sind nur die elektrischen Antriebe - Wärmekraftmaschinen können da prinzipiell nicht mithalten. #Verbrenneraus #Thermodynamik

"Disseminating AI weather forecasts has an incredibly high return on investment, generating more than $100 for farmers for each dollar invested by the government. Spreading the cost of an AI model across tens or even hundreds of millions of farmers means the per-farmer cost is extremely small."

And when will we even get all Renfe-run trains in one simple to search online timetable tool? 🤔

EU countries have cut a deal on the 2040 climate target. What worries you more: that 5 percentage points of the 90 percent reduction target can be outsourced to other countries, effectively reducing the domestic 2040 target to 85 percent, or that the start of the ETS-2 is postponed to 2028?

Deforestation in the Brazilian Amazon has fallen (again!) in 2025. 😎

Two intense and inspiring months at @columbiasipa.bsky.social have come to an end! It has been an incredibly enriching experience to immerse myself in this thriving academic community — and the kind, curious, and passionate researchers at SIPA made it easy to enjoy every day of my research stay.

6 hours 30 mins they could do from this December, with one change in Badajoz or Elvas - but they're likely not going to do though So 🤷‍♂️ Whenever I hear about these long term plans for ES-PT rail, I wonder why they're not doing the basics with what they have right now? #CrossBorderRail

We need "automated enforcement using cameras mounted on buses to capture drivers illegally blocking the bus lane. This makes them more effective, since a bus lane with cars double-parked in it is no bus lane at all." Having suffered slow buses in NYC for the last two months, this sounds amazing! 🙌

Our PhD program is hiring again! While this is a general econ program, is also gives you the chance to do, for example, quantitative energy economic research and acquire highly marketable skills in this field. So brush up your CVs and apply!

I’ve decided not to post my annual “women on the Econ job market” thread this year. Social media has splintered too much, and now that I’ve left academia I’m focused on other priorities.

Herzlichen Glückwunsch an Noosha Aubel zur Wahl als Oberbürgermeisterin von Potsdam! Freue mich für Potsdam und um so mehr, dass dieses irre Negative Campaigning der SPD die verdiente Quittung bekommen hat. @naubelpotsdam.bsky.social

María Corina Machado es de derechas, no de ultraderecha. En Venezuela no hay partidos de ultraderecha desde hace más de dos décadas. Y, en la coalición opositora que dejó en bragas al chavismo por su fraude en las últimas elecciones presidenciales, la mitad de los partidos eran de izquierdas (1/6).

Bad news for night train lovers: 🌙 The Paris–Berlin/Vienna connection ends this December, and the Berlin–Stockholm route will follow in 2026. Politics, not passengers, are derailing Europe’s night trains. We need fair conditions & stable support for sustainable travel. 🚆💔

Great article from @hannahritchie.bsky.social… and the EU ETS can fund action to reduce these non-CO2 climate impacts from aviation (and from shipping - where black carbon has a GWP of 900). It’s really good that this is getting more public attention

"Eliminating a few percent of the world’s warming is a big deal when the costs are so small. It seems insane to me that such a cheap solution is sitting there, completely untapped." We could reduce the climate impact of aviation by ≈50% in a few years, and nobody seems to be taking this seriously!

The regime's desire for authoritarianism is bottomless, but their capacity is not. Not even close. They rely on bluster and memes to make up the difference. The threat is real, but less powerful than they say. Freedom-loving Americans outnumber them by a lot. Communities can resist. Like this one:

Madrid se desborda en estos momentos en apoyo a Palestina 🇵🇸

Illegal and outrageous. But, of course, nobody will be ever prosecuted as a result of this. podcasts.apple.com/es/podcast/t...

Someone explain how this is a cancelable offense but a Fox News host saying we should murder homeless people as policy is not?

Not really an overstatement to say that the test of a free society is whether or not comedians can make fun of the country's leader on TV without repurcussions.

A complete collapse of political norms around virtue and ethics since 2016. This celebration of cruelty and violence, and the encouragement of the public to take joy in violence against others, is very unhealthy for society.

Murder is wrong. Pogroms are wrong. Using a murder to incite a pogrom against a small and vulnerable group in society is wrong. (If I’m not mistaken, an assassination was the excuse for the wave of mob but state-sanctioned violence in Russia in 1881 that gave us the term “pogrom.”)

I hadn’t seen this. Kirk, the moderate free speech guy who did politics the right way per some liberals (!), called for Biden to be executed. Meanwhile Joe Biden put out a very strong statement condemning Kirk’s killing. Both sides!

Over 125 economists signed the open letter calling on the President, Congress, and the American public to uphold the principles of Federal Reserve independence and not remove Lisa Cook without due process. There's still time to sign! And please share. #EconSky docs.google.com/document/d/1...

On my first day in Rome a month ago, I randomly walked into the newly elected Pope on the street. On my first day in New York, I randomly walk into @zohrankmamdani.bsky.social in a cafe. I guess I run into people winning elections in 2025? 😎

More than 450 million Europeans. 29 countries. 1 shared freedom. This year, we mark 40 years of Schengen! The Schengen Agreement has reshaped how over 450 million Europeans live, work and travel.

Summer time is travel time 🏝️ Take a peak where our PhD students and Alumni spent some time abroad for research stays and internships in the US 🇺🇸 🏙 New York, Los Angeles or Washington, D.C.? A difficult choice but every city offers various opportunities for early career researchers in Economics.

NYT on how the 🇪🇺🇺🇸 „deal“ is quite nonfeasible on energy issues. (Gift article 👇) Handelsblatt also writes about it, adding that issues of food regulation, digital markets and tarriffs on steel and aluminum are also wide open. Not a deal yet. www.nytimes.com/2025/07/29/c...

The German government wants to cut taxes on air travel, but who would benefit from it? 32% of Germans "never" fly, 38.5% do so less than once a year Meanwhile a small group of "frequent flyers" (7.5% who fly at least every 6 months) is responsible for 43%-49% of flights
