How liberals and conservatives respond to equality-based and proportionality-based rewards in charity advertising

Abstract

The authors conduct two studies that show how liberals and conservatives in the United States and Korea respond to charity advertising that features equality-or proportionality-based rewards for charitable giving. The findings robustly demonstrate that in both countries, liberals respond more favorably to equality-based rewards, but conservatives respond more favorably to proportionality-based rewards. Study 1, conducted in the United States, finds that liberals perceive greater effectiveness in equality-based rewards based on random drawings, but conservatives perceive more effectiveness in proportionality-based rewards based on donation amounts. Study 2, conducted in Korea, shows that liberal (conservative) donors expect to be more (less) likely to receive rewards based on equality rather than proportionality.
