Production cost structure of us hospital pharmacies: Time‐series, cross‐sectional bed size evidence
美国医院药房的生产成本结构:按床位规模分组的时间序列证据
Abstract There are current concerns about potential factor substitutions and their implications for factor employments and cost containment in US hospital pharmacies. A translog production cost model is estimated for these pharmacies, using 1981–9 times‐series data consisting of seven cross‐sectional bed size classes per year. Zellner's joint GLS estimation of three‐factor cost share equations and the parent translog cost function reveals that pairwise factor substitutions…
