Is it Better to Work When We Are Older? An Empirical Comparison Between France and Great Britain

Résumé 0

Classical literature uses the cross-sectional age-earnings profile to describe how the earnings evolve over the life cycle. Using a cohort analysis, I argue that this interpretation of age-earnings profile is not correct. I show that the cohort effects largely explain the decline observed at older ages. I illustrate this point by using a rotating panel data from France and a British longitudinal panel dataset for the period 1991 to 2007. I find no clear evidence that the earnings decline at older age, although the profiles are different between countries. Earnings for French workers rise linearly with age, with a further increase at the end of career, while it becomes flat for older workers in Great Britain. Overlapping cohorts provide an explanation of the observed decline of earnings for older workers in cross-sectional data. This suggests that cross-section age-earnings profile fails to represent the individual age-earnings profile.
