We attempt to identify the benefits of multi-unit chain membership and study the boundary conditions of the effects of chain affiliation. We test our arguments in the context of the U.S. hospital industry by examining the number of hospitals affiliated with hospital systems. We find that the number of hospitals in the system is positively associated with establishment performance. We find that the level of market competition positively moderates the relationship between the number of hospitals and establishment performance. Lastly, we find that the level of product scope negatively moderates the relationship between the number of hospitals and establishment performance.
