Examining the Correlation Between More Schooling and Better Health

Better Essays

The second article under consideration is discussing the correlation reflects causality from more schooling to better health. For example, past studies suggest that years of formal schooling completed is the most important correlate of good health; however, the relationship may be traced in part to reverse causality since a longer life expectancy increases the payoffs to investments in schooling and since healthier students may attend school for longer periods of time (Grossman, 2008). In this study, the author’s strategy is to select several older papers that point to or question causal effects. The author deals with the empirical literature on the relationship between an individual’s own health and own schooling or between child health …show more content…

It is because as a consumption commodity, health is a direct source of utility; as an investment commodity, it determines the total amount of time in a period that can be allocated to work in the market and to the production of commodities in the non-market sector (Grossman, 2008). The model is displayed below: (1) where H is a positive function of health because increases in health lower the time lost from these activities due to illness and injury (∂h/∂H≡G>0), M is the inputs of medical care, T is the own time of the consumer, S is the years of formal schooling completed, ρ is the positive parameter, and F is the linear homogeneous in M and T. Schooling has a productive efficiency effect in the sense that an increase in S raises the amount of health obtained from given amounts of M and T. Since H is homogeneous of degree one in these two input, an increase in schooling raises their marginal products on average. The specification in equation (1) assumes that a one-unit increase in S raises each marginal product by the same percentage (ρ) (Grossman, 2008). The consumer maximizesWh-πH, where W is the wage rate and π is the marginal or average cost of producing health. The first-order condition for optimal H is WG=π (2) and using this equation, one obtains formulas for the optimal percentage changes in the quantities of H and M caused by a one-unit increase in schooling (S):
