Majority support for global redistributive and climate policies.

We document majority support for policies entailing global redistribution and climate mitigation. Surveys on 40,680 respondents in 20 countries show strong majority support for a global carbon price funding equal cash transfers, called the Global Climate Scheme (GCS). Through our surveys on 8,000 respondents in the USA, France, Germany, Spain and the UK, we test several hypotheses that could reconcile strong stated support with scarce occurrences in public debates. Three quarters of Europeans and half of Americans support the GCS, even as they understand its cost to them. Using several experiments, we show that the support for the GCS is sincere and that political programmes that include it are preferred to programmes that do not. We document widespread support for other globally redistributive policies, such as increased foreign aid or a wealth tax funding low-income countries. In sum, global policies are genuinely supported by majorities, even in wealthy, contributing countries.
