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.  相似文献

论流通观念创新   总被引:1,自引:0,他引:1  
市场经济的实质和核心是交换经济、流通经济;流通不仅是中介,而且直接渗透到再生产的各个领域;流通不是地摊经济,现代流通也要运用高新技术,实现流通现代化;开放是流通的本质特征,市场经济的发达程度与流通的开放程度紧密相连;品牌本身是一种流通现象,品牌形象形成名牌和名牌经济,要在扩大对外开放中让中国自己的名牌走向世界。  相似文献

企业转让是指为了一定的营业目的通过签定合同将企业作为一个有机组织体的全部财产或部分重要财产进行有偿转让的活动。它是企业的所有权在不同的市场主体之间的移转,既不同于货物买卖也不同于企业财产的转让。企业转让制度在《德国商法典》、《日本商法典》和《韩国商法典》中都有专门规定,但在《澳门商法典》中规定的更为全面,主要涉及商号、债权债务关系、竞业禁止和劳动关系内容。建立企业转让制度是市场经济的内在体现,对我国发展经济和解决就业有着重要的现实意义,同时也符合我国建立现代产权制度的要求。  相似文献

The construction of an importance density for partially non‐Gaussian state space models is crucial when simulation methods are used for likelihood evaluation, signal extraction, and forecasting. The method of efficient importance sampling is successful in this respect, but we show that it can be implemented in a computationally more efficient manner using standard Kalman filter and smoothing methods. Efficient importance sampling is generally applicable for a wide range of models, but it is typically a custom‐built procedure. For the class of partially non‐Gaussian state space models, we present a general method for efficient importance sampling. Our novel method makes the efficient importance sampling methodology more accessible because it does not require the computation of a (possibly) complicated density kernel that needs to be tracked for each time period. The new method is illustrated for a stochastic volatility model with a Student's t distribution.  相似文献

Abstract

Attitudes are at the heart of the Theory of Reasoned Action (TRA), but problems in defining and measuring attitudes have contributed to typically low ability to predict behaviour. This article investigates the impact of potential disjuncture between evaluations that an individual externally verbalises (explicit attitudes), and evaluations that are internally held and may exist outside of conscious awareness (implicit attitudes), on the predictive ability of TRA. We study consumers’ attitudes towards eating healthy food and subsequent behaviour in a context of socially consensual behaviour. An Implicit Association Test (IAT) is used to measure implicit attitudes, and these scores are contrasted with self-reported explicit attitude scores. Ninety one participants took part in the study. We found, surprisingly, that implicit attitude has no significant effect on behavioural intention. However, a disjuncture between an individual’s implicit and explicit attitudes, reflecting internal psychological conflict, affected behaviour.  相似文献

In addition to explicit contracts, corporations issue their stakeholders implicit claims, including fair treatment of employees and the promise of continuing service to customers. Corporate value is created by selling these implicit claims for more than it costs to honour them. Recently, a new class of non-investor stakeholders, related to environmental, social and governance (ESG) issues, has arisen. Although many ESG advocates stress their role in creating shareholder value, they do not explain how this value creation occurs. This paper shows that implicit claims provide a critical link that ties non-investor stakeholders and ESG to shareholder value, both its creation and its possible destruction.  相似文献

Three metrics are designed to assess Colombian financial institutions' size, connectedness and non-substitutability as the main drivers of systemic importance: (i) centrality as net borrower in the money market network; (ii) centrality as payments originator in the large-value payment system network; and (iii) asset value of core financial services. An aggregated systemic importance index is calculated based on expert knowledge by using a fuzzy logic inference system. We use principal component analysis to calculate a benchmark index for comparison purposes. Overall similarities between both indexes put forward that expert knowledge aggregation is consistent with that based on a purely quantitative standard approach. Specific non-negligible differences concur with the nonlinear features of an approach whose intention is to replicate human reasoning. Both indexes are complementary and provide a comprehensive relative assessment of each financial institution's systemic importance in the Colombian case, in which the choice of metrics pursues the macroprudential perspective of financial stability.
