“…We also note that the sign and magnitude of spillover effects cannot be deduced by examining the empirical evidence from other industries. Although evidence from other industries shows that economies of scale are, for the most part, pervasive (Junius 1997), there is conflicting evidence as to the extent and direction of scope effects. Benefits have been demonstrated to exist in contexts such as drug R&D (Henderson and Cockburn 1996) and advertising (Silk and Berndt 1993), while diseconomies have been found in others such as transportation (Rawley and Simcoe 2010) and automobile assembly (Fisher and Ittner 1999).…”

Economies of Scale and Scope in Hospitals: An Empirical Study of Volume Spillovers

General hospitals across the world are becoming larger (i.e., admitting more patients each year) and more complex (i.e., offering a wider range of services to patients with more diverse care needs). Prior work suggests that an increase in patient volume in a hospital service is associated with reduced costs per patient in that service. However, it is unclear how volume changes in one service affect the costs of the other services in the same hospital. This paper investigates such volume-cost spillover effects between elective and emergency admissions and across specialties, using condition-level panel data comprising all acute hospital trusts in England over a period of 10 years. We provide evidence that increased elective volume at a hospital is associated with an increase in the cost of emergency care (a negative spillover). Furthermore, for emergency admissions, we find evidence that increased emergency activity in one specialty is associated with lower costs of emergency care in other specialties (a positive spillover). By contrast, we find no evidence of spillover effects across specialties for elective admissions. We discuss the implications of these findings for individual hospital growth strategies and for the regional organization of hospital systems. This paper was accepted by David Simchi-Levi, operations management.

“…To increase the flow of young specialists to DIC enterprises a complex approach based on interaction of academic institutions and industrial enterprises is necessary to be developed. To provide the activity of future specialists three flows should be organized: youth; industrial enterprises that need new young specialists; scientists (Junius, 1997). Having united these three flows in the conditions of the system of additional education the increase of quality human resources in DIC can be made.…”

“…Inadequate improvements in student outcomes and a turbulent environment have led systems and consortia to adapt in ways that include: (a) strengthening the vitality of the campuses that comprise them, (b) coordinating the work of campuses across shared goals and strategies, and (c) leveraging the collective capacity of campuses toward improved student outcomes. These efforts to better position systems and consortia to create economies of scale and scope may result in increasing efficiencies that allow for resources to be reallocated toward student success (Clark, ; Junius, ). Specifically, systems and consortia and campuses are targeting high‐impact practices, such as scaling UR (Kuh, ).…”
