Evaluation of Efficiency in Primary Health Care Centres: An Application of Data Envelopment Analysis

The aim of this paper is to analyse one of the principal problems in primary health care management: the evaluation of efficiency in primary health care centres. Given the special characteristics of measuring outcome in primary care it is necessary to evaluate the performance of centres from a quality perspective too. The methodology used, DEA (Data Envelopment Analysis), allows us to introduce quantitative and qualitative variables in a sample of primary care centres in a Spanish province. Once the efficiency of the different centres is known, we investigate the sensitivity of the methodology to changes in the definition of outputs used.     

我国采掘业上市公司并购绩效及其外部扩张

筛选沪深两市采掘业上市公司中在2008年发生并购的公司作为样本,对比全行业和未发生并购企业数据,采用数据包络分析方法(DEA)对长期并购绩效进行分析。研究结果显示,并购活动在短期内会对企业造成绩效冲击,但长期来看,并购有利于公司绩效的提升。     

MUTUAL FUND PERFORMANCE EVALUATION – APPLICATION OF SYSTEM BCC MODEL

For the first time, this research adopts the system BCC model in data envelopment analysis in order to evaluate mutual fund performance and compares the results between the BCC model and the system BCC model. This study is based on the sample of stock funds and balanced funds in Taiwan, with the empirical results summarised as follows. (i) Under the system BCC model, the average score of balanced funds is greater than the average score of stock funds. (ii) There is a significant difference in efficiency scores between the BCC model and the system BCC model, and it is proper to adopt the system BCC model. (iii) The number of major reference sets that have been referenced under the BCC model is larger than under the system BCC model. (iv) If we neglect the distinctions between stock funds and balanced funds, there will be errors on performance assessment. Ultimately, the results reveal that there is a significant difference between the two models. Provided no consideration is made for the funds belonging to two different systems, errors in performance evaluation are inevitable. This research provides investors with both a more accurate and comprehensive evaluation method.     

Merger and acquisitions in South African banking: A network DEA model

Banking in South Africa is known for its small number of companies that operate as an oligopoly. This paper presents a strategic fit assessment of mergers and acquisitions (M&A) in South African banks. A network DEA (Data Envelopment Analysis) approach is adopted to compute the impact of contextual variables on several types of efficiency scores of the resulting virtual merged banks: global (merger), technical (learning), harmony (scope), and scale (size) efficiencies. The impact of contextual variables related to the origin of the bank and its type is tested by means of a set of several robust regressions to handle dependent variables bounded in 0 and 1: Tobit, Simplex, and Beta. The results reveal that bank type and origin impact virtual efficiency levels. However, the findings also show that harmony and scale effects are negligible due to the oligopolistic structure of banking in South Africa.

网络视角下中国各地区创新过程效率研究:基于我国八大经济区的比较

创新效率问题是学术界关注的焦点.本文从解剖创新过程中的要素流动机理出发,揭示了创新过程的网络化特征,并通过构建网络DEA模型,测算了创新过程整体效率、"创新资源转换"效率与"创新知识转化"效率.以我国八大经济区为研究对象发现:"创新资源转换"与"创新知识转化"效率的主要影响因素不同,前者受到R&D人员区域分布结构影响,后者受到各地区经济发展水平差异的影响;区域创新过程整体效率与"创新知识转化"效率高度相关;区域创新整体效率与"创新知识转化"效率在样本期间稳步上升;整体效率与"创新知识转化"效率出现地区追赶的收敛现象,"创新资源转换"阶段是整体效率发散的隐患.     

评价供应链信息共享的交叉效率

供应链管理作为一个整体系统集成了内部和外部的企业流程，通过信息技术，公司可以有效的管理产品流和有关信息的问题。文章通过一个仿真模型设计了不同的信息共享方案来对供应链的绩效进行分析，使用普通的数据包络分析（DEA）模型来测量绩效，并应用了交叉数据包络分析来解决这个问题。结果表明需求信息共享的方案是最有效的一个方案。对产量信息和／或库存信息进行共享，而不对需求信息进行共享，将会干扰制造商的生产，导致误解产生，并放大牛鞭效应。     

A performance evaluation model for international tourist hotels in Taiwan—An application of the relational network DEA

This research utilizes relational network data envelopment analysis to construct a model to analyze the efficiency and effectiveness of international tourist hotels (ITHs) in Taiwan. The different production processes within the hotel are evaluated, as well as the relationships between efficiency, effectiveness, and overall performance. Finally, based on the results, we recommend ways of enhancing the overall performance of the hotel industry in Taiwan.     

New Zealand Bank Mergers and Efficiency Gains

ABSTRACT

This paper uses accounting ratios and DEA (Data Envelopment Analysis) to explore the efficiency impacts of 6 bank mergers in New Zealand between 1989 and 1998. The paper is the first reported application of DEA to the New Zealand banking sector, and its methodology is based around that used by Avkiran in his study published in the Journal of Banking and Finance in 1999 (Avkiran, 1999b).

Consistent with earlier research, acquiring banks were found to be generally larger than their targets, although they were not consistently more efficient. In a majority of cases the merger led to an increase in efficiency, consistent with a trend observed for the banking sector as a whole. No clear conclusions could be drawn on possible public benefits from the mergers.
