🚨New Paper🚨

Would people support global redistributive policies?

Surveys in 20 countries (🇪🇺🇺🇸🇨🇳🇮🇳🇯🇵🇧🇷🇿🇦...) show strong majority support for:
- global climate policies
- a global wealth tax
- a global democratic assembly
- transfers from high- to low-income countries

1/N With @ADechezlepretre, @T_Kruse_, @BPlanterose, @asanchezchico, @S_Stantcheva, we found that people support some global climate policies as much as the most preferred national ones.

Importantly, 85% stated that climate policies should be at the >global< level.

Proposition intéressante : faire dépendre le prix de l'essence des revenus de l'acheteur.
On pourrait aller plus loin : définir les amendes en proportion du revenu et/ou autoriser les commerçants à faire dépendre le prix du revenu de l'acheteur.
Y a de la littérature éco sur ça ?

Ça nécessite de lier une donnée fiscale (le revenu) à un moyen de paiement tout en préservant l'anonymat, ce que permet déjà une cryptomonnaie comme
@GNUtaler (développée à l'@Inria).
Pour les amendes, ça semble une mesure de bon sens, sans regret.

With @ADechezlepretre, @S_Stantcheva, @BPlanterose, Ana Sanchez Chico and Tobias Kruse,
We surveyed climate attitudes in 20 countries covering 72% of global CO2 emissions.
In brief, people around the World want ambitious, global, and fair climate policies.
oecd-ilibrary.org/deliver/3406f2… People support ambitious action but are pessimistic that we will succeed in halting climate change during this century.
World leaders: please prove them wrong!

🇪🇺 There is little information about it in the media, so I read (rapidly) the final report of the Conference on the Future of E.
🔴It reveals consensus among European and their representatives on a fairer & more integrated EU on some (not all) issues.🧵⬇️
futureu.europa.eu The conference spanned 3 years and 4 initiatives:
1. A temporary digital platform gathered proposals from 50k participants (5M people looked at the website).
2. Six European countries organised national panels, the others also organised initiatives (I skipped this part).

Hi #EconTwitter!
A thread about my job market paper:

"Disagreement Aversion"

JMP link: ssrn.com/abstract=39641…

Although my other works document the political economy of climate change with empirical evidence (e.g. aeaweb.org/articles?id=10…), this paper is more theoretical.
1/20 Experts disagree.
Take climate sensitivity, a parameter crucial to model climate change: climate modelers disagree on its probability distribution.
How should we aggregate these experts' distributions? How should we make decisions under expert disagreement?
