This table reports the marginal rates of substitution (MRSs) of quality for distance derived from the conditional logit model (see equation 6). For the survival and readmission rates, the MRS given by equation (6) is divided by 100 to put it into percentage point terms. Only one quality measure is used at a time in each logit model. Standard errors are analytic and clustered at the market level.
The sample is all patients with the condition in 2008 who stayed in their market of residence for treatment. The choice set for a patient is all hospitals in his market with the quality measure available that treated at least one patient in 2008. The mean and SD miles statistics are taken from the patients in the column’s risk-adjusted survival sample (risk-adjusted readmission for hip/knee replacement). All MRSs in a column are evaluated at this mean.
