Cohort Effects Don’t (Fully) Explain Why Well-Being Is U-Shaped in Age %D 2007 %8 2007 Nov %I Institute of Labor Economics (IZA) %C Bonn %7 IZA Discussion Paper %N 3170 %U https://www.iza.org/index.php/publications/dp3170 %X The statistical analysis of cross-section data very often reveals a U-shaped relationship between subjective well-being and age. This paper uses fourteen waves of British panel data to distinguish between two potential explanations of this shape: a pure life-cycle or aging effect, and a fixed cohort effect depending on year of birth. Panel analysis controlling for fixed effects continues to produce a U-shaped relationship between well-being and age, although this U-shape is flatter for life satisfaction than for the GHQ measure of mental well-being. The pattern of the estimated cohort effects also differs between the two well-being measures and, to an extent, by demographic group. In particular, those born earlier report more positive GHQ scores, controlling for their current age; this phenomenon is especially prevalent for women. %K subjective well-being %K cohorts %K fixed effects %K panel data
