Using a hedonic wage-amenity model, this paper examines the valuation of medical inputs into the production of health. The data used in this study include the incomes, demographics and measures of human capital for households in eastern North Carolina with county level medical input supply. These data allow an estimate of the marginal value of medical care inputs such as the physician to population ratio and the availability of specialized services in an area of the country where the lack of available medical care has been of particular concern to policy makers. Our results indicate that while health care inputs are not a significant determinant of earnings overall, they are important in counties that have been designated as medically underserved. In underserved counties each additional physician per 10,000 individuals in the county decreases earnings by about 11.6%. This suggests that physicians act as an amenity and workers are willing to accept lower wages to locate in counties with a higher physician to population ratio.

This paper examines the thesis that monopsony power is an important determinant of wages in nursing labor markets. Using data from the 1985-93 Current Population Surveys, measures of relative nurse/non-nurse wage rates for 252 labor markets are constructed. Contrary to predictions from the monopsony model, no positive relationship exists between relative nursing wages and hospital density or market size. Nor is support found for the presence of monopsony power based on evidence on union wage premiums, slopes of experience profiles, or the mix of RN to total hospital employment.
