  A tailor-made internet survey experiment provides individuals with
information on their income positions to examine their effects on subjective
well-being. In the first survey, respondents were asked about their household
income and subjective well-being. Based on the data collected, three different
respondents' income positions within the residential locality, within a group
of the same educational background, and cohort were obtained. In the follow-up
survey for the treatment group, respondents are informed of their income
positions and then asked for subjective well-being. Key findings are that,
after obtaining information, a higher individual's income position improves
their subjective well-being. The effects varied according to individual
characteristics and proxies.
