Measuring Hospital Performance in the Presence of Quasi-Fixed Inputs: An Analysis of Québec Hospitals

This research proposes an approach to measure hospital performance based on a generalization of Banker and Morey (1986) and Førsund (1996). This approach considers quasi-fixed inputs explicitly, calculates their implicit cost, and quantifies returns to scale. The performance measure is decomposed into allocative and technical inefficiencies. Based on a very complete data set of Québec hospitals, we find that significant inefficiencies of up to 17% ($700 CAN million) could have been saved through improved performance. Postestimation analyses that include qualitative measures of care suggest that differences in performance are attributable to differences in management or unobservable quality of care rather than patient case mix.     

A new continuous distribution and two new families of distributions based on the exponential

Recent work on social status led to derivation of a new continuous distribution based on the exponential. The new variate, termed the ring(2)-exponential, in turn leads to derivation of two closely related new families of continuous distributions, the mirror-exponential and the ring-exponential. Both the standard exponential and the ring(2)-exponential are special cases of both the new families. In this paper, we first focus on the ring(2)-exponential, describing its derivation and examining its properties, and next introduce the two new families, describing their derivation and initiating exploration of their properties. The mirror-exponential arises naturally in the study of status; the ring-exponential arises from the mathematical structure of the ring(2)-exponential. Both have the potential for broad application in diverse contexts across science and engineering. Within sociobehavioral contexts, the new mirror-exponential may have application to the problem of approximating the form and inequality of the wage distribution.

市场拥挤、财政支出和税后资本平均产出关系分析

税后资本平均产出的高低对私人部门投资决策产生重要影响,但是我国自1994年分税制改革以来,税后资本平均产出处于不断下降趋势,与此同时,财政支出规模呈不断扩大趋势。本文在财政支出解决市场拥挤框架下分析了财政支出对税后资本平均产出的影响,在理论分析中,说明财政通过增加支出缓解市场拥挤来影响税后资本平均产出,其影响程度由税率、财政支出的产出弹性、市场拥挤程度决定。在实证分析中,计量检验了世界范围内和中国地方政府财政支出对税后资本平均产出的影响,并结合现实对计量结果给予解释。
