Why a positive link between age and income-related health inequality?
() and Ulf-G Gerdtham
Abstract: This study uses Swedish data to analyze why the SES-health
gradient increases with ageing. Since different measures of SES and health
capture different aspects, we use this information to explore the age
increase in health inequality and to discriminate between three types of
explanations, namely: i) age increase in the causal SES effect; ii)
reversed health effect on SES, and iii) lifecycle variation in the
measurement errors in SES and health.
Thus, our analysis points in the
direction that the age increase in health inequality is primarily caused by
a reversed causality going from health to annual income, and the probable
mechanism is health affecting the labour supply of the individual. In
addition the study report that the age variation in health inequality seem
to have increased over time, and during the 1980th the age variation was
rather limited. The evidence in our study is not conclusive, but all
evidence documented agrees and supports this conclusion.
