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 nursejnon-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.
