Abstract: Nine studies find that people believe their money has greater purchasing power than the same quantity of others’ money. Using a variety of products from socks to clocks to chocolates, we found that participants thought the same amount of money could buy more when it belonged to themselves versus others—a pattern that extended to undesirable products. Participants also believed their money—in the form of donations, taxes, fines, and fees—would help charities and governments more than others’ money. We tested six mechanisms based on psychological distance, the endowment effect, wishful thinking, better-than-average biases, pain of payment, and beliefs about product preferences. Only a psychological distance mechanism received support. Specifically, we found that the perceived purchasing power of other people’s money decreased logarithmically as others’ psychological distance from the self increased, consistent with psychological distance’s subadditive property. Further supporting a psychological distance mechanism, we found that framing one’s own money as distant (versus near) reduced the self-other difference in perceived purchasing power. Our results suggest that beliefs about the value of money depend on who owns it, and we discuss implications for marketing, management, psychology, and economics.
