[bionet.population-bio] mortality and resources

rogers@ANTHRO.UTAH.EDU (Alan R. Rogers) (07/13/90)

Does anyone know how access to resources (or wealth in humans) affects age-
specific mortality rates?  Is it reasonable to assume that an extra unit of
resource will decrease the mortality of a 20 year old by the same amount as
that of a 40 year old?  Or is the effect more nearly proportional to the
original mortality rate?  In other words, do we want a model of the form

                    u(x,w) = u(x,0) + f(w)                       (1)

or of the form

                    u(x,w) = u(x,0) f(w)                         (2)

or maybe even

                1 - u(x,w) = (1 - u(x,0)) f(w)                   (3)

where u(x,w) is the mortality rate of individuals of age x and "wealth" w,
and f(w) is the effect of wealth on mortality.  Is there some better
alternative?
