Wealth redistribution promotes happiness.

Area of Science:

• Psychology
• Economics
• Behavioral Science

Background:

• Decades of research explore the money-happiness link, but lack experimental data across diverse economic groups.
• Previous studies often focus on specific populations, limiting generalizability to the global economic spectrum.

Purpose of the Study:

• To experimentally quantify the happiness gains from wealth redistribution across diverse global economic strata.
• To investigate the causal effect of direct cash transfers on individual happiness and well-being.

Main Methods:

• A real-world experiment involving high-net-worth donors redistributing US$2 million.
• US$10,000 cash transfers were provided to 200 individuals globally.
• Preregistered analyses were used to evaluate the impact on happiness.

Main Results:

• Cash transfers substantially increased happiness across economically diverse individuals worldwide.
• Recipients in lower-income countries reported happiness gains three times greater than those in higher-income countries.
• Positive effects on happiness were observed for individuals with household incomes up to US$123,000.

Conclusions:

• Direct cash transfers are a potent tool for increasing global happiness and well-being.
• Wealth redistribution via cash transfers yields significant, measurable happiness benefits across a wide economic range.
• The impact of financial aid on happiness is disproportionately larger in lower-income contexts.
