Here is the redistribution obtained from the median preferred parameters: 5% of (nominal) world income redistributed from the top 18% to the bottom 49%, financing a minimum income of $287/month (in PPP).
Such redistribution would be a game-changer for the global poor.

Finally, people can choose interactively their preferred global income redistribution.
You can do it too here: www.centre-cired.fr/en/custom-gl...
Below is a video explaining how the task works.
Interestingly, 48% choose a custom redistribution that makes them lose while only 9% choose to win.

🧐Now, a word on support for more radical proposals.
Most people would accept an income tax on the global top 1% (resp. 3%): above $120k (resp. $80k) per year. This tax would collect 2% (resp. 5%) of world income and alleviate poverty below $250 (resp. $400) per month (in PPP).

🔴To sum up, most people in high-income countries would accept global redistribution policies.
🟢People value climate change and global poverty, and agree their country should finance sustainable development.
🟡Few mobilize due to the low priority of this issue, but many could.

Belief that global redistribution is likely increases by 7 pp among informed respondents (33%->40%).
Under warm glow, support should *decrease* among convinced respondents.
I find the contrary: being convinced causally *increases* the number of global policies supported by 18 pp.

In case of warm glow, people express support to enjoy moral comfort as long as global policies appear unlikely and support harmless.
To test that, I inform a random half of respondents of ongoing international negotiations/initiatives.
The treatment increases support by 1 pp.

Support for an international policy decreases only slightly as country coverage shrinks.
We also see that for a wealth tax with 30% funding LICs: support is reduced from 74% in the case of global coverage to 68% if only a few countries participate.

Support for global redistribution stems from a sense of duty or empathy, not guilt or interest.
Consistent with this finding, there is no majority support for reparations for slavery or colonization. => The decolonial narrative is not the most effective for global redistrib.

Direct questions confirm this finding:
- 36% are more likely to vote for a party if it is part of a global coalition for sustainable development (vs. 17% less likely)
- 68% would support such a coalition (including 52% of the 584 millionaires who answered)
- 45% are universalists

The conjoint experiment indicates that global redistribution may be vote-determining for some people. A program is
- 4 p.p. more likely to be preferred if it contains a globally redistributive wealth tax
- 4 p.p. less likely to be preferred if it contains cutting development aid.
- 4 p.p. more likely to be preferred if it contains a globally redistributive wealth tax
- 4 p.p. less likely to be preferred if it contains cutting development aid.

Before respondents could infer the survey's topic, they had to allocate the revenue from a global wealth tax.
87% of respondents allocate a positive amount to the global item. This item receives an average preferred share of 17.5%, slightly below an equal split of 20%.
