The main purposes are to develop a method for measuring the economies of scope, which involves the use of non-parametric production frontiers and does not require information on input prices; and to apply this method to individual hospital data drawn from a sample of Spanish hospitals. The results confirm the presence of technical inefficiencies and also of potential and non-exploited economies of scope. The combination that produces most economies of scope is that of gynaecology and paediatrics.
