It has become received wisdom in Brussels and Washington that there is a new “euro-sclerosis”: that the EU economy is lagging the US This view is wrong A little primer on the measurement of productivity – and why reports of the economic death of Europe are greatly exaggerated🧵

Un grand merci aux aixoises et aux aixois d'être venus si nombreux à Sciences Po pour parler de l'avenir de la justice fiscale et de la démocratie. La tournée de conférences publiques se poursuivra en 2026 dans toute la France -- à très bientôt !

Un grand merci aux amiénoises et amiénois d'être venus si nombreux hier pour parler de l'impôt plancher sur les ultra-riches et de l'avenir de la justice fiscale

400 personnes à la Librairie des Volcans, plus de 1 000 à la faculté, toutes curieuses de s’approprier les savoirs, de réfléchir aux nouveaux horizons de la démocratie : C’est à Clermont-Ferrand que la grande bataille citoyenne pour la justice fiscale a commencé 🧵

Aujourd’hui sort mon nouveau livre «Les milliardaires ne paient pas d’impôt sur le revenu et nous allons y mettre fin.»🧵

Opinion: More than any other western European country, France is dominated by powerful billionaires paying relatively low taxes. Most voters agree that France should cut its deficit, and the majority says: the super-rich first. on.ft.com/4hedHHZ

Tout juste sortis de l'imprimerie. En librairie le 24 octobre. Très hâte !

Parfois c’est ce qui nous est le plus proche que l’on met le plus de temps à voir. Pendant quinze ans j’ai cartographié les grandes fortunes mondiales, objectivé leurs techniques pour contourner l’impôt dans les paradis fiscaux, du Luxembourg aux îles vierges britanniques... 🧵

🚨New working paper🚨 In this updated work with Annette Alstadsaeter, @bluebery-planterose.com , @gabrielzucman.bsky.social and @andokl.bsky.social , we use leaked data to chart the rise of offshore real estate in Dubai www.taxobservatory.eu//www-site/up...

Matching the Forbes 400 to tax data finds that they pay a total tax rate of 24 percent of economic income, lower than the 30 percent tax rate paid on average in the US, from Akcan S. Balkir, Emmanuel Saez, Danny Yagan, and Gabriel Zucman https://www.nber.org/papers/w34170

New Bureau of Economic Analysis data: In 2023 US multinationals booked 42% of their foreign profits in the main tax havens After 2 years of unprecedented decline, profit shifting seems to be rising again Back to the lung-run trend that started in 1978?

Think how much you pay in taxes. Now think about this: The ultra-wealthy pay between 0% and 0.6% of their wealth in individual income tax – around 0.6% in a country like the United States and 0.1% in a country like France. We wrote about it in @lemonde.fr www.lemonde.fr/en/opinion/a...

An international call for action just got louder: Today, 7 Nobel Laureates have issued a powerful call for a minimum tax on the ultra-wealthy in Le Monde Here’s a quick breakdown of the debate—and where things stand globally 🧵 www.lemonde.fr/en/opinion/a...

Fewer reporting requirements had large negative effects on French wealth tax compliance, w/ 35% of wealth taxpayers missing in affected brackets & evading 10% of payments each year. @bgarbinti.bsky.social @s-stantcheva.bsky.social @gabrielzucman.bsky.social et al. cepr.org/voxeu/column... #EconSky

Quelle que soit la façon dont on regarde les choses, les milliardaires sont considérablement moins imposés que le reste de la population dans son ensemble Merci au Grand Continent de m’avoir permis de revenir sur cette réalité incontestable et inacceptable legrandcontinent.eu/fr/2025/07/0...

The G7 is exempting American multinationals from the global minimum tax. It’s pathetic and scandalous.

Predictable—and yet shameful and pathetic—capitulation of the G7, who agrees to let US multinationals escape the global minimum tax of 15% A clear illustration of why we need fundamentally new rules of the game www.nytimes.com/2025/06/27/b...

Après Olivier Blanchard et Jean Pisani-Ferry, Patrick Artus appelle à mettre en oeuvre la taxe Zucman. Le gouvernement dispose désormais : - de toute la caution intellectuelle nécessaire - d'une majorité à l'Assemblée Une situation rare ! www.alternatives-economiques.fr/patrick-artu...

New post: A minimum tax on billionaires mainlymacro.blogspot.com/2025/06/a-mi... The very rich pay a much lower percentage of their income in tax than almost everyone else. The 'Zucman tax' addresses this problem directly in a way designed to attract the maximum popular support.

L’impôt plancher sur le patrimoine a été adopté par l’Assemblée nationale Il est plébiscité par les Français Sa logique économique est limpide Le Sénat, en première lecture, le rejette aujourd’hui Que fait on maintenant ? On continue ! 🧵

Pour que les Français acceptent la nécessaire consolidation des finances publiques, il faut que la charge en soit équitablement répartie. Ma tribune @lemonde avec O. Blanchard et G. Zucman. www.lemonde.fr/idees/articl...

Olivier Blanchard, Jean Pisani-Ferry et Gabriel Zucman : « Nous partageons le constat qu’un impôt plancher sur les grandes fortunes est le plus efficace face à l’inégalité fiscale »

ah these countries where the head of state and oligarchs spend their time self-dealing or fighting for contracts, laws, and everything always revolves around this ... couldn't happen here, fortunately

Imagine if Latin American countries acted as one and said: "Our billionaires must pay their fair share" That's how global change starts So great to take part in the event hosted by @icrict.bsky.social Rumbo Colective & Oxfam at the Chilean Congress Library today—thanks for having me!

💥 “It sounds like we should tax billionaires…” A 2% minimum tax on the ultra-rich is the punchline with a plan: make them pay what ordinary people already do. With growing global momentum, this is no longer just theory. Read: www.ft.com/content/859e...

Zucman and co were proven exactly right—extreme wealth inequality makes democracy and the rule of law untenable. A global wealth tax is probably the most pro-democracy policy out there. www.ft.com/content/859e...
