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.

New WP w/@thomaspiketty.bsky.social !

We build a database of World Historical BoP (wbop.world) and study +200 years of economic transactions

Key takeaway: power plays a key role in global imbalances.
Collective rules are needed to correct them.

Feedback very welcome!

Why are we not doing more to fight climate change? New study surveys 40k people in 20 countries to understand 1/ what drives support/opposition to important climate policies 2/ how much people know about climate change & 3/ how info can change perceptions socialeconomicslab.org/internationa...

We hope sharing this data will inspire further research on this crucial topic! 🚀🚀

📂 The raw data are also available on our repository for further analysis: doi.org/10.3886/E208...

Header of the tool webpage describing how the interactive tool works

Example of how to use the tool. It shows that you can select a block of question and navigate it to find a question. Then you can pick the country (here Canada) and the socio-economic group (here gender) for which you want to explore the data.

🔍Data Explorer Tool: Second tool allows to dive into the full survey data! Explore climate attitudes globally by socio-economic groups

Ever wonder how people in Canada perceive climate change by gender? You can now look at it

Use the tool here: bluebery-planterose.com/fighting-cli...

4/5 🧵

Show the tool with the full table showing support by country for each policy

Show example for support for subsidies in Denmark by gender

🛠️Climate Policy Support Tool: The first tool allows you to explore support for all climate policies across 20 countries!

It's interactive! Click on a cell to see how support varies by socio-economic groups within each country

3/5 🧵

Graph showing share of people who think climate change is an important problem and share that think their country should do something to fight climate change, for each of the 20 countries surveyed

Our study, with 40,000 respondents from 20 countries, provides new data on attitudes toward climate change

It contains a lot of information on various policies, more than we could analyze in the paper. Hence why we wanted to make the data easily explorable

2/5 🧵

Really happy to see the paper finally out! 🥳

Stay tuned to @s-stantcheva.bsky.social thread on the results!

In addition to the paper, I've also developed tools to explore the survey data and help people better understand global perceptions of climate change and support for climate policies🌱

Super excited to see our paper on attitudes towards climate change out in the @aeajournals.bsky.social American Economic Review today! So much more work to do on this pressing issue--data is publicly available! Short summary thread coming!

Bravo, super parcours ! C'était vraiment un plaisir de vous suivre et de vous voir partager votre bonne humeur chaque jour 🎉

Victoire historique :

La loi pour taxer les milliardaires a été adoptée par l’Assemblée Nationale après d’intenses débats.

C’est un pas de géant pour la France et cela pourrait inspirer d’autres pays.

Une immense avancée !

Cela semble absurde, et j’ai été choqué la première fois que je l’ai compris, mais la France – il n'y a pas d'autre mot – est bien un paradis fiscal pour milliardaire

Explications détaillées 🧵

Thrilled to see our paper published! Huge thanks to @aeajournals.bsky.social and everyone who supported this work!

I'm immensely grateful to my amazing co-authors (especially @s-stantcheva.bsky.social and @adrien-fabre.bsky.social who are around here) 🥳 🥳

Face a l’arrivée de Trump, il y a urgence à repenser les relations économiques internationales.

Sereinement, mais radicalement.
