We show that older male pensioners have substantially lower incomes th
an younger pensioners. There are a number of possible reasons for this
including under-indexation of private pensions and the running down o
f income producing assets. In fact we find that cohort differences mor
e than account for the lower incomes of older pensioners in the sense
that the mean income of order pensioners is actually higher than the m
ean income of the same cohort of pensioners when they were younger. We
explore a number of possible reasons for this and conclude that it;is
driven by differential mortality between richer and poorer pensioners
. We show how this manifests itself in a long time series of cross-sec
tional datasets.
