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

Abstract: 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 c… Show more

“…We used a fixed effects estimator to identify the causal effects of FFS on the outcomes, and hence we control for the time variant characteristics to remove potential trend effects: Hospital level:Since the data we collected contains the information of hospital level, we used a binary variable to indicate if a hospital belongs to grade III (tertiary hospital) or not. Hospital size and Staff number: Hospital size by controlling bed size and the number of full-time employees [ 16 , 22 , 23 , 29 , 34 , 35 ]. We take the natural logarithm of beds and the number of employees to account for the heavy tails in this distribution.…”

“…A diversified product portfolio may enable organizations to leverage existing capabilities, cross-learn from the varied categories, and hedge against demand and supply uncertainties of their operating environment (Ding et al, 2019). Extant literature identifies multiple mechanisms such as learning from variety, complementarity of capabilities in related areas and spillovers by which diversification may be posited to improve organizational knowledge (Boh et al, 2007;Narayanan et al, 2009;Schilling et al, 2003;Clark and Huckman, 2012;Freeman et al, 2019).…”

“…Our research complements and serves to address the call for research in this area (e.g. Senot et al, 2016;Roth et al, 2019;Ding et al, 2019;Dreyfus et al, 2020) by accounting for heterogeneity in (in)efficiency of care in examining the interrelationships between throughput, experiential quality and net revenue from operations, and the role of operational drivers such as diversification of care in improving these outcomes of care along the production frontier.…”

“…Two papers (Catena, Dopson, & Holweg, 2020;Lee, Venkataraman, Heim, Roth, & Chilingerian, 2020) examine how operational policies set by a national health system affect the delivery of healthcare. Two papers (Ding, Peng, Heim, &Jordan, 2020 andMishra, Salzarulo, &Modi, 2020) examine how strategic approaches taken by hospitals, possibly in response to national health-system policies, affect the delivery of healthcare in those hospitals. Two papers describe hospital-emergency-department operations (Berry Jaeker & Tucker, 2020;Davis, Zobel, Khansa, & Glick, 2020).…”
