Purpose and Perspective¶
The Health sector derives key indicators that are directly relevant to SDG targets and that feedback to other sectors and processes in the model. These include access to basic health care, prevalence of undernourishment, and proportion of population exposed to PM2.5 levels exceeding World Health Organization guidelines.
Income is a prime consideration in access to health care. In this sector we use the distribution of average after tax income to realistically capture the effects of income inequality and poverty on access to health care. Also, we use the distribution of average income with the food poverty line to assess the prevalence of undernourishment.
Model Structure and Major Assumptions¶
Exogenous Input Variables¶
Initial health care implemented expenditure - Units: Rlcu
Initial per capita health care implemented expenditure – Units: Rlcu/person
Initial average access to basic health care - Units: Dmnl
Initial per capita cereal production – Units: Ton/(year*person)
Initial real food poverty line – Units: Rlcu (year*person)
Initial total PM2.5 emissions – Units: Kt/year
Initial PM2.5 mean annual exposure – Units: g/CM/year
Distribution of income and poverty levels have profound influence on health, including access to basic health care and undernourishment. The effect of income distribution on access to health care is modeled using a functional form that causes access to basic health care to increase at a decreasing rate, asymptotically approaching 1 as real average income by percentile approaches a saturation income. The effects of the other factors further accelerate such progress towards 100% access to basic health care.
