Service mix, market competition, and cost efficiency: A longitudinal study of U.S. hospitals Academic Article uri icon

abstract

  • © 2019 Association for Supply Chain Management, Inc. We examine the longitudinal impact of service mix on cost efficiency in U.S. acute care general hospitals. We propose two different dimensions of service mix, with the first dimension capturing internal emphasis on specific service lines (i.e., specialization) and the second dimension reflecting the deviation of a hospital from the average level of specialization for hospitals in the same service area (i.e., differentiation). We hypothesize that as the level of a hospital's specialization increases, hospital cost efficiency should improve at a decreasing rate. We also hypothesize that differentiation helps improve cost efficiency in competitive markets. Lastly, we examine whether acute care general hospitals can use service mix as an operational lever to improve cost efficiency when specialty hospitals are present in the same local markets. We find strong empirical support for the hypothesized relationships.
