Health expenditure and income in the United States
This paper investigates the long-run economic relationship between health care expenditure and income in the US at a State level. Using a panel of 49 US States over the period 1980–2004, we study the non‐stationarity and co‐integration between health spending and income, ultimately measuring income elasticity of health care. The tests we adopt allow us to explicitly control for cross‐section dependence and unobserved heterogeneity. Specifically, in our regression equations we assume that the error has a multifactor structure, which may capture global shocks and local spill overs in health expenditure. Our results suggest that health care is a necessity rather than a luxury, with an elasticity much smaller than that estimated in other US studies. Further, we detect significant spatial concentration in US health spending. Our broad perspective of cross‐section dependence as well as the methods used to capture it give new insights on the debate over the relationship between health spending and income.
