Preview: ... dent variables to test hypotheses that come from X-inefficiency Theory. The study was based on 1989 data for 195 Pennsylvania acute care hospitals. This data base was chosen because of the availability of patient-level severity of illness data, a measure of output that is not available from most data sources. The stochastic frontier analysis models estimated mean inefficiency scores that ranged from 0.075 to 0.180. The addition of the DRG case mix index (CMI) reduced estimated inefficiency by more than 50%. The incremental effect of a severity of illness variable to an equation with CMI was very small. The second-stage results suggest inefficiency and are inversely associated with regulatory pressures and industry concentration.<br><br>Here's a hint: mixtures can always be broken down into other things. <br>1. Sea water is a mixture because it has a ton of different things in it, like salt and water and various microorganisms. <br>2. Cooking oil is a mixture. It is a blend of various kinds of oils. <br>3.
