当代企业为达到适岗适才的目的,需要应用人才测评的方法挑选和评价员工.而结构化心理学量表往往导致被测评人对问题的回答和个性表现不一定真实可靠.罗夏墨迹测验正好弥补了这方面的缺陷.然而对于罗夏墨迹测验的质疑从一开始就未停止.本文将综合罗夏墨迹测验相关研究,对争论的焦点问题进行回顾,并对罗夏测验在人才测评中存在的问题及其实用价值进行探讨. 相似文献

通常认为模糊DEA评价是用于测度管理有效性的一种方法,但是实际运行中由于有些模糊DEA有效单元信息贫乏,导致评价结果难以令人信服.本文提出的基于优势生产前沿面的DEA有效单元再评价方法克服了传统评价的问题,更有效地反映了评价单元的管理进步效果,经过理论分析和实践检验,是目前用于管理有效性评价的最佳方法之一.其特性表现在,将优势前沿面方法应用在非营利组织的测评管理中,通过构造有效性更强的新决策单元实现对DEA有效单元的区分和排序,克服了原来使用的靠DEA基于权重和判断准则进行再评价的缺点,具有现实可行性和有效性,评价结果具有较好的稳定性和可比性,能够对模糊DEA有效单元进行有效区分.研究使管理有效性方法在非营利组织评价中的应用更加具有理论意义和实际价值. 相似文献

员工效率工资与企业的管理效率分析 总被引:1,自引:0,他引:1
本文在文献回顾基础上分析了效率工资的solow模型和shapiro-stiglitz模型存在的局限性,认为由于工资合约具有非完备性特点,通过工资合约对员工进行完全激励是困难的;之后基于重复博弈理论构建了同时考虑内外部劳动力市场要求的效率工资模型,运用博弈理论分析了企业和员工在效率工资博弈过程中的行为和策略,揭示了该模型较之均衡效率工资模型具有的更为丰富的经济内涵,从八个方面阐述了效率工资对企业提高管理效率的价值,认为效率工资需要与其它激励机制相互补充.建立全面报酬体系才能实现其激励的目的. 相似文献

In this article, we use data envelopment analysis combined with principal component analysis to evaluate the efficiency of online retailers in search advertising. We examine various efficiency model specifications involving several resource and performance‐related variables in search advertising. Our analysis based on 200 retailers suggests different efficiency patterns for multichannel and Web‐only retailers. The results of our efficiency pattern analysis indicate that the performance metrics, impressions, online sales, click‐through rate, and conversion rate together reveal differences in efficiency mainly for multichannel retailers. On the other hand, ad positions in sponsored and organic links reveal differences in efficiency for Web‐only retailers. In terms of overall efficiency, we find that multichannel retailers occupy relatively most of the top positions. These results contribute to organizational level understanding of search advertising practices in online retailing and offer insights into keyword management, resource utilization, and performance metrics in search advertising campaigns. 相似文献

In this paper, we generalize the notion of Pareto efficiency to make it applicable to environments with endogenous populations. Two efficiency concepts are proposed: ℘‐efficiency and 𝒜‐efficiency. The two concepts differ in how they treat potential agents that are not born. We show that these concepts are closely related to the notion of Pareto efficiency when fertility is exogenous. We prove a version of the first welfare theorem for Barro–Becker type fertility choice models and discuss how this result can be generalized. Finally, we study examples of equilibrium settings in which fertility decisions are not efficient, and we classify them into settings where inefficiencies arise inside the family and settings where they arise across families. 相似文献

Abstract. This work analyses the links between credit and labour markets highlighting the influence of credit market inefficiencies on employment. We argue that if banks are not efficient in monitoring the borrowers in the presence of asymmetric information, credit market imperfections have real effects. We estimate dynamic equations using system generalized method of moments (GMM) for bank loans and employment on panel data for Italian firms. The system GMM estimates indicate that the impact of credit market on employment is higher where the local financial market is less developed, asymmetric information is widespread, bank managers are less efficient in assessing the firms' solvency and do not use appropriate methods to evaluate the borrowers' payback capacity. 相似文献

We consider large double auctions with private values. Values need be neither symmetric nor independent. Multiple units may be owned or desired. Participation may be stochastic. We introduce a very mild notion of “a little independence.” We prove that all nontrivial equilibria of auctions that satisfy this notion are asymptotically efficient. For any α>0, inefficiency disappears at rate 1/n2‐α. 相似文献

The conventional data envelopment analysis (DEA) models for measuring the relative efficiency of a set of decision making units (DMUs), without considering the operations of the component processes, often produce misleading results, and network models have thus been recommended. This paper discusses the development of a network DEA model for systems with a hierarchical structure. It is shown that the hierarchical structure is equivalent to a parallel structure, with the components being the units at the bottom of the hierarchy. Due to the characteristics of a parallel system, the efficiency of a hierarchical system is thus a weighted average of those of the units at the bottom of the hierarchy. A hypothetic example shows that the proposed model is able to distinguish the order of the efficient DMUs evaluated by the conventional DEA model. Moreover, it provides the efficiencies of the functions of the DMU, which enables managers to identify areas of weakness, and thus better focus efforts to improve overall performance. 相似文献
