DEA APPLIED TO A GAUTENG SAMPLE OF PUBLIC HOSPITALS1

The research presented in this paper provides an analysis of the delivery of a few health care services by the public sector in Gauteng, South Africa. The data for the study was especially difficult to collect, suggesting the need for hospital level data information systems, as well as staff who are trained to analyze the information collected. The empirical results from the analysis suggest that services provided by small‐scale medical facilities waste fewer resources, while medical centres offering more technical services, such as surgeries, also appear to deliver medical services more efficiently.     

我国区域经济增长的开发性金融支持效应分析——基于面板数据模型的研究

随着我国经济增长方式从粗放型向节约型可持续发展方向转变,开发性金融理论与实践日益受到重视。本文利用面板数据分析了开发性金融对区域经济发展的影响,结果表明,近几年来开发性金融对区域经济增长的促进作用是明显的,对缩小区域差异的作用不明显,但通过分析认为开发性金融是缩小区域经济差异的有效政策手段。     

中国区域经济协调发展中的投资导向研究

总体上以投资促经济增长的发展战略,有可能因忽视区域特点而产生误导.有鉴于此,本文应用省区面板数据,分别从总体和分区域地检验了投资与增长之间的Granger因果关系,并在因果关系的条件下计算了投资对增长的长期影响系数.结果发现,在不同区域投资与增长之间的因果关系呈现出不同的特点,而且投资对增长的影响方向与作用力度迥异.文章最后也尝试着寻求推动区域经济发展的共同因素.本文的理论含义是,总体分析因为忽略了区域特征而产生严重误导;政策建议是,投资应侧重东、中部地区,尤其是中部地区,而西部地区更应注重科技投入和引进外资等发展策略.     

Here come the men in black Technology and anxiety in the postmodern age

This review of the film Men in Black argues that what used to be alarming in the science fiction genre has now become its main source of humour. As a reactionary response to the dystopic X-Files, MiB is an elaborate parody which seeks to recuperate ideological ground lost by the X-Files' examination of gender and technology in contemporary culture. Anxiety about the roles of technology, gender and the state are replaced by humour about the notion of anxiety itself. Anxious we may be at the close of the millenium, but MiB tells us to just laugh it all away.     

The Effect of Sample Size on the Mean Efficiency in DEA with an Application to Electricity Distribution in Australia,Sweden and New Zealand

This study examines the effect of sample size on the mean productive efficiency of firms when the efficiency is evaluated using the non-parametric approach of Data Envelopment Analysis. By employing Monte Carlo simulation, we show how the mean efficiency is related to the sample size. The paper discusses the implications for international comparisons. As an application, we investigate the efficiency of the electricity distribution industries in Australia, Sweden and New Zealand.     

对管理会计方法的几点质疑

管理会计学科知识中涉及到大量的分析模型和数据指标，在现实生活中往往被人们不加推敲地生搬硬套，视其为当然的权威、绝对地正确，使管理会计的学习应用趋于教条化。而实际上，管理会计还是一门发展并不十分成熟的学科，其中存在许多值得我们进一步研究和论证的问题。例如，有些方法已明显与现实脱节，有些方法还停留在以静止的观点看问题。有的不考虑管理会计这一信息系统中数据信息的取得成本，有的分析模型一味追求精确复杂反而推动了实际应用价值，有的分析方法干脆就不具备多少严谨性和可信性。本文针对以上问题进行了讨论，旨在抛砖引玉，使管理会计这一学科更加健全和完善。     

Technology gaps in European banking: Put the blame on inputs or outputs?

This paper investigates the production efficiency of 12 European banking systems over the period 1997–2004, taking into account possible technology heterogeneity. Using a non-parametric metafrontier framework, efficiency and metatechnology ratio measures are computed and decomposed into input- and output-invariant components. Empirical findings indicate the existence of significant and rather increasing technology heterogeneity within European banking. A typology of the national banking systems is also developed, based on the overall productive performance with respect to the European technological edge, the absorptive capacity and the role of knowledge spillover effects. Decomposition results draw attention to catching up policies focusing on input and/or output scale adjustments.     

Testing population variance in case of one sample and the difference of variances in case of two samples: Example of wage and pension data sets in Serbia

Testing one population variance and the difference in variances of two populations based on the ordinary t-statistics combined with the bootstrap method are suggested in this article. Suggested techniques are combined with Hall's transformation approach. Application of presented methods in domain of real economic data set is described and analyzed. We compare the outputs of suggested methods and traditional methods for considered data set. The results show that these introduced methods have small advantages in comparisons with traditional methods especially for small samples.

Evaluating the efficiency and productivity change within government subsidy recipients of a national technology innovation research and development program

This study analyzes the efficiency and productivity change within government subsidy recipients of a national technology innovation research and development (R&D) program. We examine 6,990 government‐sponsored, completed R&D projects during the last three performance follow‐up survey years from 2010 to 2012, and present a design of the sample of panel data to cope with the typical R&D performance time lag using a set of massive observations associated with completed R&D projects for the past 7 years from 2005 to 2011. In particular, data envelopment analysis is adopted to measure the efficiency and productivity change, which is measured in the Malmquist index. Parametric and nonparametric statistical tests are carried out to check for statistically significant differences among the characteristics regarding the types of government subsidy recipients. This study's major findings are as follows. First, during the entire period analyzed (2010–2012), there was a similar yearly pattern of statistically significant differences in the government subsidy means among the recipient types. In contrast, there were no obviously equivalent differences in the efficiency and productivity change. Second, the productivity had increased year on year, but the increments were reduced from year to year. Third, the productivity change was induced mainly by the Frontier‐shift, which indicates overall technology innovation progress, compared with the Catch‐up, which only indicates a simple increase in the efficiency. In particular, in this empirical analysis, the recipient types of ‘national laboratory’ and ‘large company’ had relatively larger sizes of government subsidies per project. However, the efficiency and productivity change of these types was not better than the others. This implies, therefore, that the government should control the ratio of the subsidy to the total R&D budget with an appropriate upper limit.

• I empirically evaluate the productivity change within a national technology innovation R&D program.
• I design a sample of panel data to cope with the typical R&D performance time lag using massive observations.
• There is no obvious relationship between the government subsidy size and R&D productivity change.
• Some particular types of government subsidy recipient are inferior in terms of R&D productivity change.
• It practically implies that the government should control the ratio of the subsidy to the total R&D budget.
