Bivariate Correlations of Hospital Price with Observable Factors, 2008–2011

The x-axis reflects the level of the bivariate correlations between key variables featured in our regressions and hospitals’ regression-adjusted inpatient prices that are risk-adjusted for DRG, age, and sex. The bars show the 95% confidence intervals surrounding the correlations. Because these are bivariate correlations, “duopoly” is duopoly or monopoly and the implicit omitted category is triopoly or greater. “Triopoly” is triopoly, duopoly, or monopoly. For government and nonprofit, the omitted category is private for-profit hospital.
