There are some aspects of the European RFEC and its implementation today that could benefit from increased harmonisation; there are others in which substantial accommodation to local, national or regional circumstances and preferences is desirable or required. 相似文献

This paper develops a unified framework to analyze the dynamics of firm investment in countries with poor legal enforcement. The firm's technology edge over the government generates endogenous property rights. Industry variation in the technology gap predicts a sectoral pecking-order of expropriations. Long-run investment distortions may be Pareto superior relative to persistent investment at the static optimum. The dynamics of investment and transfers depend on whether incentives (backloading) or efficiency (frontloading) concerns dominate at the initial division of surplus. An increase in government efficiency may reduce its welfare. The model provides a technology-driven rationale for the widespread use of conglomerate structures in emerging market countries. 相似文献

In forecasting a time series, one may be asked to communicate the likely distribution of the future actual value, often expressed as a confidence interval. Whilst the accuracy (calibration) of these intervals has dominated most studies to date, this paper is concerned with other possible characteristics of the intervals. It reports a study in which the prevalence and determinants of the symmetry of judgemental confidence intervals in time series forecasting was examined. Most prior work has assumed that this interval is symmetrically placed around the forecast. However, this study shows that people generally estimate asymmetric confidence intervals where the forecast is not the midpoint of the estimated interval. Many of these intervals are grossly asymmetric. Results indicate that the placement of the forecast in relation to the last actual value of a time series is a major determinant of the direction and size of the asymmetry. 相似文献

We investigate how learning and the task performance of individuals are affected by different forms of knowledge transfer. Whereas previous research has proven the positive performance impacts of knowledge transfer, self-observation and feedback mechanisms individually, we explore the cumulative effect of these factors on learning and performance. With the help of two laboratory experimental studies reproducing manufacturing tasks that are typical for industrial production, we show that explicit knowledge transfer is superior to other forms of knowledge transfer. Externally provided performance feedback in the form of cost information and non-financial performance indicators has no effect on the order of different forms of knowledge transfer. Moreover, external feedback does not even have an additional significant performance effect on learning new tasks irrespective of the type of knowledge transfer. 相似文献

中国乡城流动人口社会网络复杂性特征分析 总被引:3,自引:0,他引:3
借助社会网络等非正式制度方式实现再社会化是乡城流动人口融入城市生活的主要途径之一。对流动人口社会网络的分析不仅可以揭示其网络结构特点,也将为进一步研究流动人口再社会化过程提供理论基础。采用深圳市流动人口专项调查中的整体网络数据,借助复杂性科学,尤其是复杂网络的研究方法,系统分析了乡城流动人口社会支持网络与讨论网络的复杂性特征。在乡城流动人口社会网络中广泛存在小世界现象和无标度特性等复杂网络特征。复杂性科学可以为分析诸如乡城流动人口这样的复杂系统提供有效方法,也是拓展复杂性科学,尤其是复杂网络应用领域的有益尝试。 相似文献

Current empirical research on logistics' relationships with other departments has mostly neglected the interface with production. On the basis of data from 387 manufacturing companies, we answer a recent call for research and extend the literature by examining effective working relationships and achieved integration between the production and logistics functions regarding their performance impacts and their antecedents. With respect to the former, we take a resource‐based perspective, showing that integration achieved between the production and logistics functions drives distribution service performance by serving as a pivotal capability element in the resource–capability–value chain. Within this chain, effective working relationships constitute the underlying resources and prove to be a strong driver of achieved integration. With respect to antecedents, we employ the theory of cooperation and competition and identify positive goal interdependence to substantially improve working relationships between production and logistics. Furthermore, we find this effect to be amplified via formalized performance measurement systems. 相似文献

The paper argues for conceptualizing technology as a socio-technical ensemble which emerges from the socio-political context of the organization. This perspective is used to inform a case study carried out within a consumer goods company, where the focus is upon the configuration of work and technology associated with the job of sales representative. It is argued that the acquiescence and compliance of the sales representatives are to be understood primarily on the basis of senior management's effective deployment of its power resource through 'enacting the environment', the configuration and utilization of the ensemble, and its employment strategy. 'Closure' and 'stabilization' had occurred, and the ensemble was operating on a number of levels. 相似文献

The local indivisibility of space complicates general equilibrium analysis. Mazzoleni and Montesano (1984, p. 286), suggest that the usual reasoning of the non-spatial analyses of competitive equilibrium can be performed in the context of a commodity space that contains subsets of land. This space, however, lacks a linear structure, so it resists application of the usual reasoning. Two examples will show that Mazzoleni and Montesano's existence results are flawed. 相似文献
