Production of Health - Mortality Rates How do we measure health? Mortality rates, morbidity (illness) rates, and disability days Research shows that the marginal contribution of health care is significant but small: we are at the flat part of the production function Auster et al. (1969) estimated a health production function D=AM α E β C γ I δ D = mortality rate, M = medial care expenditures, E = education expenditures, I = income, C = cigarette consumption, A = constant The elasticity of mortality rates with respect to medical care to be around -0.1 The elasticity of education is about -0.2 The elasticity of cigarettes is about -0.1 The elasticity of income is positive – in general, there are mixed results for the effect of income on health Some empirical studies show that socioeconomic status (e.g., education) and lifestyle (e.g., not smoking) may have a greater MP than health care 3/3/2010 Econ 157 Mortimer 3

Production of Health - Mortality Rates Incremental benefits, however, still exceed incremental costs of health care Gains in life expectancy may be small in terms of years but can be large in terms of $ The production function can be shifted out with new technologies and medical research Murphy and Topel (2006) show that the value of medical research is much greater than the cost (“The Value of Health and Longevity”) Post-1970 gains in life expectancy added about $3.2 trillion per
