RELATIVE INCOME, SUICIDAL IDEATION, AND LIFE SATISFACTION: EVIDENCE FROM SOUTH KOREA

The relative income hypothesis predicts that an individual's level of happiness decreases in others' income. We examine its empirical relevance in South Korea using large survey data from the Korea Welfare Panel Study. We find evidence that higher peer income is strongly correlated with life satisfaction, but its effect on suicidal ideation is modest and largely insignificant. We also find that the effect of peer income is highly heterogeneous; those who consider themselves relatively poorer seem to be more strongly (and adversely) affected by their relative disadvantage than those relatively richer are (positively) affected by their relative advantage.
