Aggregate efficiency of industry and its groups: the case of Queensland public hospitals

In this paper, we explore the efficiency of different groups hospitals in Queensland, Australia, focusing on teaching and non-teaching hospitals, by adapting most recent developments statistical analysis aggregate efficiency. We focus two approaches: bootstrap approach proposed Simar Zelenyuk (J Appl Econ 22(7):1367–1394, 2007) central limit theorems recently developed (Oper Res 66(1):137–149, 2018), (Eur J Oper Res, 2020). To adapt these developments, extend to context where there are several sub-groups population. Using real data Queensland public found that significantly less efficient than when benchmarking is done with respect constant returns scale frontier, but more variable frontier.
