The authors analyze the economic efficiency of rural credit unions of large size compared to a group of credit unions. The methodology is based on the analysis of profitability, productivity and efficiency ratios and on the estimation of a Cobb–Douglas cost function. The evolution during the period 1989–1994 as well as the situation at the end of this period are examined. The same methodology is used to study the rural credit unions individually.  相似文献

This paper examines rail access charges for high speed trains on new high speed lines in Europe and the impact these have on the market position of high speed rail. It examines the latest evidence on the marginal infrastructure and external costs of high speed rail, finding that the best evidence is that these are both not more than 2 €/train-km. However, current legislation states that environmental costs should not be charged for unless they are charged for on competing modes. Mark ups based on Ramsey pricing principles might reasonably raise prices by 100–200%, given that infrastructure charges are only a part of the final price of rail. The paper then examines the actual prices charged in the main European countries operating high speed trains and the impact these are likely to have on traffic levels and mode split. It is found that mark ups often exceed even the optimal Ramsey levels, with a significant impact on rail volumes and market share. It is concluded that, whilst it is not surprising that governments wish to recover some of the construction costs of new high speed rail lines from users, they should consider carefully whether the level of charges is actually significantly reducing traffic on and benefits from these lines.  相似文献

The dramatic impact of the 2008 crisis on the Italian economy led to policy responses including structural reforms and labour market liberalisation to reverse the worrisome output and employment trends. A key action by the Italian government, the evocatively named Jobs Act of 2014, has deeply changed Italian industrial relations. The Jobs Act has introduced a new contract type that substantially limits workers’ rights to reinstatement in case of fi rms invalidly fi ring them. This article frames the Jobs Act within the overall liberalisation process begun in Italy in the 1990s, providing an initial evaluation of its impacts. Using detailed data sources, we show that the expected boost in employment cannot be detected, the share of temporary contracts over open-ended ones has increased and the number of part-time contracts has risen. This evidence suggests that the Jobs Act is failing to achieve its main goals.  相似文献

Technology education has long struggled to establish itself as an equal partner in general education and often struggled to gain recognition for the value of its instruction. Frequently technology educators tout the effectiveness of their programs based on anecdotal evidence gathered from their classroom experiences on how their instructional methods empower students to learn. Although technology education originated without any meaningful input from cognitive science research, it appears that technology education instruction methods are remarkably consonant with findings from cognitive science that define good instruction. Specifically, there is considerable accord between how instruction in technology education and cognitively based instructional models such as collaborative learning, socially distributed expertise, design/engineering, and project-based instruction can be connected. The role of the cognitive research findings on instruction could inform a long over-due theoretical grounding of instruction in technology education. The absence of research on learning and instruction in technology education could be attributed to a lack of theoretical grounding in this relatively new field. This paper examines four cognitively based models of instruction and reviews the relationships between research in the cognitive sciences on learning and instruction in technology education. The consonance between the research recommendations from the cognitive sciences and practice in technology education instruction could serve to stimulate debate on the theoretical grounding of an emerging field of study.  相似文献

Human resources audit   总被引:4,自引:0,他引:4  
Human resource management (HRM) has experienced a strong evolution. In order to provide useful information to managers, it is necessary to evaluate the results generated by the design and implementation of personnel policies. This is the goal of the HR audit that includes two different analyses and valuations: the HR policies and their level of fit with the strategy of the firm, and the characteristics of human capital. Several criteria have been used to assess different HR policies. Nevertheless, the measurement of the value that human capital brings to the firm is a very complex topic. Consequently, different models are being presented that aim to properly solve this challenge. This paper will analyze the HR function from two perspectives: the evaluation of the implemented policies and the quality of human capital in relation to real competencies, and the capability to learn and develop new skills.  相似文献

The rate of market and technological changes has accelerated in the last years. This turbulent environment requires new methods and techniques to bring successful new products to the marketplace. Much attention has focused on new development techniques, but little empirical research has been conducted to validate these techniques. In this study, the relationship between popular new development techniques and new product success is examined. Our findings suggest that only a subset of these popular techniques is significantly related with new product success in Spanish firms. The study also identifies the main contributors to new product development (NPD) effectiveness in Spanish firms.  相似文献

In ques to la voro si introduce la classeU delle funzioni reali definite in un reticolo che sono funzioni di utilità di una classe di decisorti detti avversi al rischio e si caratterizza la dominancza stocastica secondo la classeU.
Summary The aim of this paper is to generalize a result of [4] about stochastic dominance under the assumption of risk aversion. The generalization consists in considering the case of random variables defined on a lattice. We introduce a class of real valued utility functions on a lattice, we show their properties in terms of comparison of lotteries and risk aversiion. The main result of the paper is a characterization of stochastic dominance through this class of functions.
