OxTalks is Changing
OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Aging and Heterogeneity in the Analysis of Mortality
The association between the mortality rate and individual characteristics such as social class, income, education, and gender is different at different ages. This is often interpreted as evidence that the causal effects at the individual level change with age. However, in the presence of unobserved heterogeneity, dynamic selection may occur at a higher speed among subjects with observed characteristics that increase the mortality rate, and this will also, by itself, generate age variation in the association between characteristics and mortality. We show that these explanations can be distinguished empirically. We derive a simple test and we apply it to data on mortality among the elderly from the US National Longitudinal Mortality Study. We find that dynamic selection explains observed mortality variation across age for many covariates, but selection can not explain the large relative mortality improvement among black men at high ages. We extend our approach to the macro level, using country as the unit of observation. Dynamic selection explains the attenuation of the association of GDP and mortality at high ages.
