Eine seriöse Wissenschaftlerin revidiert dann ihre Meinung, wenn ihr die Daten durchgehend widersprechen. Ich kenne keine seriöse Studie, die das greedflation Narrativ unterstützt. Tut sie aber nicht. Und wer da widerspricht ist misogyn? Das kann man doch nicht ernst nehmen.
Come join our macro group @UniBonn! We're hiring two postdocs for three years, starting September 2027. Empirical and theoretical macroeconomists (broadly defined) welcome.
Apply by 15 Nov 2026: econjobmarket.org/positions/…

Le spread has reached today 150 basis points. The question on everyone's mind is: can the ECB intervene? And if so, can it activate TPI? My personal view is that it cannot. This question and the situation we have reached was the central question motivating "Crisis Cycle" , my Princeton University Press book, with @masuch_klaus and @JohnHCochrane.
The purpose of TPI is to be used "in jurisdictions experiencing a deterioration in financing conditions not warranted by country-specific fundamentals." The French problem is a deterioration in country-specific fundamentals: 5.4% deficit in 2026, debt increasing towards 122%, the undoing of the pension reform.
The ECB's text says TPI purchases end when tensions "are due to country fundamentals." So you cannot start when you are in the ending conditions.
Also, the 3rd test of TPI says: is the debt trajectory sustainable? Lagarde has said (see Klaus' tweet below) it is "not on path to be brought back under control". I think Lagarde is answering clearly the question on the 3rd test.
On paper, France passes two tests ("Compliance with EU fiscal framework? "The Commission said in June yes; And "severe macro imbalances" as given by an open excessive imbalance procedure, again ok on paper).
If France needs the ECB, there is a route: an ESM program, like the ones during the Euro crisis, requiring reforms (basically getting the pensions in order will suffice), plus the OMT which allow the ECB to act when a country is subject to a program.
If the ECB calls this current situation a liquidity problem, we will have an open route to monetary bailouts.

German newspapers and I normally tend to disagree a bit on whom to interview as economic expert but the FAZ and @WinandWvp are spot on to interview Jesus! 👇
A couple of weeks ago, I gave a long interview to Frankfurter Allgemeine, and the article by @WinandWvp based on it just came out.
It was a really fun conversation. Because space was limited, the article didn't include much of it, but we discussed immigration, its political consequences, the CDU’s strategic choices over the past decades, constitutional patriotism, and climate change, among other topics.
The article is in German, but any automatic translator will do a fair job.
BTW, being called "Der große @JesusFerna7026" is really cool😀 I feel like Friedrich II. (Preußen).
Our new report on the euro area business cycle is out! See Giovanni’s thread for the main findings. @cepr_org

📣 Level up in HANK modeling: BASEforHANK is back!
Following our Winter School, @christianbaye13, @bornecon and I are running the BASEforHANK Spring School, March 1–10, 2027, at @DIW_Berlin.
Want to solve and estimate HANK models for your own research? Join us for hands-on training in Julia with BASEtoolbox.jl; from household problems and equilibrium computation to solving and estimating heterogeneous-agent business-cycle models.
Already working with HANK? We’ll also cover:
Two-country HANK models
Aggregate uncertainty with ambiguity-averse agents
Higher-order perturbation using the DEGM approach
💻 March 1–5: foundations, online
📍 March 8–10: advanced HANK methods, in person at DIW Berlin.
Morning lectures, afternoon hands-on sessions in small groups.
For PhD students, postdocs and professionals—whether you’re getting started or extending your HANK toolkit.
⏰ Apply by November 15, 2026. An early-bird academic discount is available for eligible PhD students and postdocs, with enrollment by December 6. Enrollment runs until mid January 2027.
Details & applications: diw.de/en/diw_01.c.1020133.e…
Please share with interested students and colleagues. See you online and in Berlin!

Die Bebauung des Tempelhofer Feldes wuerde die Aktionäre von Vonovia kostengünstiger “enteignen”’

Replying to @BenniTanovic
Wenn man im Wertegerüst der alten Republik an die Vermögen der Wohnungskonzerne will, dann weist man Bauland aus und überarbeitet Bebauungspläne so wie @TschenPe s Regierung in HH. Dann gibt es auch tatsächlich mehr Wohnungen.

🧵 #Tankrabatt ist nicht alleine: In der letzten Dekade wurden viele neue (Dauer)subventionen geschaffen: E-Auto-Prämien, GEG-Heizungsförderung, Industriestrompreis, Mütterrente & Gastro-Privilegien... Zusammen ca. 37 Mrd. €/Jahr.
Was wäre, hätte man Arbeit entlastet?

My 2 cents for students:
1. Unless you find a Prof who works shoulder-to-shoulder with you, a pre-doc won’t make you a more mature PhD candidate.
2. Pre-doc coauthorships may eat into PhD solo-research time.
3. Life is short: commit to a 5-year PhD. Make every second count.

ifo Institut: PISA-Abstieg gefährdet unseren Wohlstand
Der eklatante Abstieg der PISA-Ergebnisse muss zu einem Umdenken in der Bildung führen. Die Vermittlung der Basiskompetenzen muss höchste Priorität haben.

Um ein wenig Öl ins Feuer zu gießen: Es ging ja auch um Renten und das “wohlverdiente Privileg” wie Hensel es nannte. Wenn der Westen/Osten seine Renten alleine zahlen und der Bundeszuschuss nach Steueraufkommen verteilt würde, läge der Beitragssatz bei ca 15,5% West bzw. 43% Ost
Replying to @BachmannRudi @RBingener
Schon die erste Wortmeldung war so unerträglich. Sicher war das Kohl Wort von blühenden Landschaften ungeschickt. Nur ist der reale Konsum pro Kopf im Osten 89-2024 um ca 120% gewachsen, im Westen um 30% und in Gelsenkirchen bestenfalls um 0. Wo sind die Verlierer der Einheit?
