Money vs. Happiness

The question whether the rich are more satisfied with their lives is often taken for granted, even though surveys, like the Gallup World Poll, show that the relationship between subjective well-being and income is often weak, except in low-income countries in Africa and South Asia. Researcher Daniel Kahneman and his collaborators, for example, report that the correlation between household income and reported life satisfaction or happiness with life typically ranges from 0.15 to 0.30. There are a few plausible reasons. First, growth in income mostly has a transitory effect on individuals’ reported life satisfaction, as they adapt to material goods. Second, relative income, rather than the level of income, affects well-being — earning more or less than others looms larger than how much one earns. Third, though average life satisfaction in countries tends to rise with GDP per capita at low levels of income, there is little increase in life satisfaction once GDP per capita exceeds $10,000 (in purchasing power parity). This article studies the relationships between subjective well-being, which is narrowly defined to focus on economic well-being in India, and variants of income, based on the only panel survey in India Human Development Survey (IHDS).
