Madison and Chakravarty's data for system membership are from the American Hospital Association. We updated the data with merger acquisition data from other sources such as Modern Healthcare, a hospital trade publication. We checked the data using a hospital systems database constructed for California hospitals, which has a high degree of correlation with Madison and Chakravarty's database

We estimated robust standard errors to take into account any unobserved factors that might be clustered at the hospital level. This robust standard error method also takes into account any unobserved correlations at the Metropolitan Statistical Area level, which is the level of aggregation at which managed care market characteristics are measured

We performed several tests. First, to test for the possibility that the market penetration of health maintenance organizations is not random, we followed previous studies, reestimating our models but using labor market characteristics that others have used to predict managed care penetration. The results from this test were similar to those in our original models. Second, since payer-mix data were not available for adjusted days, we used payer-specific discharge data to construct payer mix measures, finding that adjusted days and admissions were highly correlated (0.84). And third, we used pooled data across years to provide more precise estimates (the pooled coefficients were essentially the weighted average of the coefficients from the two separate models)

Under this specification, the dependent variable becomes the average revenue per unit of output (adjusted patient days), and the estimated coefficients for the other variables can be interpreted as the marginal relationship between the independent variables, including concentration measures, on average hospital price

We measured each hospital's market separately, using actual hospitalspecific ZIP code-level data on patient flow and following the detailed method described in Note 13. We used Medicare discharge data to construct annual, hospital-specific indexes based on each hospital's geographic market, adjusted for hospitals that are part of multihospital systems with other members in the same geographic market
