Elsevier has dismissed Richard Tol as editor of the highly successful "Energy Economics". His account of the alleged and the actual reasons casts an even darker shadow over the academic publishing business.

🆕 The ‘missing intercept’ problem with going from micro to macro

Today on VoxDev, @benmoll.bsky.social (LSE) and @olihanney.bsky.social explain the problem with scaling cross-sectional estimates to the aggregate level, and discuss solutions for economists: voxdev.org/topic/method...

Many of the 'facts' that travel the furthest from economic research are based on a flawed method of scaling cross-sectional estimates to the aggregate.

@benmoll.bsky.social and I have written about this 'missing intercept' problem, and what economists can do about it, here ⤵️

Stronger together - support for 🇺🇦 from private individuals, coordinated with @oechssler.bsky.social:

200 people gave at least 200€. Combined with extra donations, the total is about 60.000€.

The money is already in Ukraine. Thank you!

According to this @zdfde.bsky.social Politbarometer poll, 76% of Germans are in favour of more defence spending with new debt.

This includes 90% of CDU voters, 52% of Die Linke voters and even 70% of FDP voters.

A fiscal public opinion revolution.

If one person gives a euro to Ukraine, the result is €1.

If two people give 2 each, it is €4.

If 3,000 give 3,000 each, it is 9 million.

Let’s coordinate, here 👇

SO true. "Oh noes I don't know how we're going to rearm we've only got one of the world's great industrial powerhouses looking for a new growth area whose government can borrow very cheaply, woe is us".

The European Union remains a funny animal.

Outside observers: rich place, lots of industry, lower debt levels than US/China. Should be able to rearm quickly and cheaply if they coordinate decision-making.

Leaders on the inside: I don’t trust my neighbour so let’s bicker while the house burns down.

To better compare Ukraine aid to defence spending, I turned the @kiel.institute figures into annual % of GDP, using the latest GDP data available and some extrapolation.

Europe will need to pull all the levers to up its defence spending How to get to 3.5%

Did some of the maths in this week's The @economist.com on EU defence spending and Ukraine aid if America withdraws.

Doable, but requires putting a lot of money on the table. www.economist.com/europe/2025/...

To spend big, Germany’s next government may need EU help How self-imposed constraints could lead to a bizarre outcome

"In an ironic twist, Germany might end up dependent on EU debt, which it usually opposes, to fund its armed forces [as EU debt does not fall under the debt brake]."

Big congrats to this year's Sloan Fellows!

... and I say this as someone who has contributed to developing such linearization methods myself benjaminmoll.com/WIMM/.

Of course these methods are very useful for answering some questions. But just not for many others. (Plus the downsides in Fatih's thread)

@benmoll.bsky.social might have an opinion inspired by his work on rational expectations in HA model (benjaminmoll.com/challenge/)

For the one interested, @benmoll.bsky.social will present @igier @bocconi on Tuesday at 4.30pm

I couldn't agree more!

The excessive focus on linearized solutions to HA models is a bit like the old joke about the drunk who is looking for a key under a lamppost because that's where the light is.

As I keep saying to German journos: the Finnish foreign minister is a native German speaker. Rare opportunity to get her on radio and TV, as this 👇 really matters.

Nichts von den US-Ankündigungen ist besonders überraschend. Aber sie machen einmal mehr deutlich, dass Europa seine Sicherheit selbst organisieren muss, wenn es bestehen will. Die Wiederherstellung von Sicherheit muss unbedingte Priorität der nächsten Bundesregierung sein.
