“The Link between Income, Income Inequality, and Prosocial Behavior around the World: A Multiverse Approach”, 2021 (; similar):
The questions of whether high-income individuals are more prosocial than low-income individuals and whether income inequality moderates this effect have received extensive attention.
We shed new light on this topic by analyzing a large-scale dataset with a representative sample of respondents from 133 countries (N = 948,837). We conduct a multiverse analysis with 30 statistical models: 15 models predicting the likelihood of donating money to charity and 15 models predicting the likelihood of volunteering time to an organization.
Across all model specifications, high-income individuals were more likely to donate their money and volunteer their time than low-income individuals. High-income individuals were more likely to engage in prosocial behavior under high (vs. low) income inequality.
Avenues for future research and potential mechanisms are discussed.
