This paper uses longitudinal data from the Gfirman Socioeconomic Panel (GSOEP) to analyze the course of subjective well-being over the life cycle. The long time dimension offers an opportunity to disentangle ageing effects from fixed birth co- hort effects. The paper _finds that the U-shaped pattern of life satisfaction over age is less supported in a longitudinal analysis, and that the observed trajectory can vary across model specifications. Moreover, assets and material well-being seem to play an important role in detfirmining the course of satisfaction over life time. The upsurge of happiness after mid-life seems to be more robust to model specifications, which might imply that the latter is inherent to mankind.
