Only a few years ago European low-cost service was almost exclusively focused on Western Europe. However, the enlargement of the European Union to East Central Europe has brought with it an expansion of the liberalised air space, thereby offering new opportunities for service to Community airlines. Low-cost air service has since diversified in favour of new west–east air links that represent almost 60% new routes that have opened up between Western and East Central Europe. The western low-cost airlines dominate the market rather than Eastern European ones. The new west–east routes reflect new forms of mobility: post-migration flows from the east by those who have gone to work in Western Europe, new tourist practices and undoubtedly new types of business as well.  相似文献

In the past few years, few human resource practices have received as much attention as multi-source feedback systems (MSFSs). In the US and Canada, it is estimated that over one-third of organizations are using some form of MSFS and recent surveys show that this practice is still gaining popularity. Concurrently, a substantial amount of literature has focused on the effectiveness of this performance management practice. However, while few would dispute the popularity of MSFS, relatively little has been published on the use of these systems outside North America and thus little is known about their form and effectiveness in international contexts. This paper outlines the results of an international survey of MSFS. Interview data from HR managers and consultants from Argentina, Australia, China, Slovakia, Spain and the UK demonstrate that MSFS are being implemented, in slightly different ways, in each of these six countries. The main challenges in the application of MSFS in these various countries are the communication efforts necessary before and after implementation, and the inherent difficulty in giving and receiving feedback. The results of this study also provide data as to the perceived future of MSFS in each of the countries surveyed.  相似文献

This paper examines the generalization of the regulated production function. It characterizes the set of admissible regulatory constraints that are compatible with the existence of a regulated production function in a sufficiently weak framework to encompass the usual rate-of-return constraints à la Averch and Johnson and value constraints.  相似文献

Summary. This paper studies monotone risk aversion, the aversion to monotone, mean-preserving increase in risk (Quiggin [21]), in the Rank Dependent Expected Utility (RDEU) model. This model replaces expected utility by another functional, characterized by two functions, a utility function u in conjunction with a probability-perception function f. Monotone mean-preserving increases in risk are closely related to the notion of comparative dispersion introduced by Bickel and Lehmann [3,4] in Non-parametric Statistics. We present a characterization of the pairs (u,f) of monotone risk averse decision makers, based on an index of greediness G u of the utility function u and an index of pessimism P f of the probability perception function f: the decision maker is monotone risk averse if and only if . The index of greediness (non-concavity) of u is the supremum of taken over . The index of pessimism of f is the infimum of taken over 0 < v < 1. Thus, , with G u = 1 iff u is concave. If then , i.e., f is majorized by the identity function. Since P f = 1 for Expected Utility maximizers, forces u to be concave in this case; thus, the characterization of risk aversion as is a direct generalization from EU to RDEU. A novel element is that concavity of u is not necessary. In fact, u must be concave only if P f = 1.Received: 10 April 2001, Revised: 18 November 2003, JEL Classification Numbers: D81.

We study how uncertainty and risk aversion affect international agreements to supply global public goods. We consider a benchmark model with homogeneous countries and linear payoffs. When countries directly contribute to a public good, uncertainty tends to lower signatories' efforts but may increase participation. Despite risk aversion, uncertainty may improve welfare. In contrast, when countries try to reduce a global public bad, uncertainty tends to increase signatories' efforts and decrease participation. In that case, an ex-ante reduction of uncertainty may have a large positive multiplier effect on welfare.  相似文献

In recent years, scholars have increasingly turned their attention to the separate areas of corporate social responsibility (CSR) and supply chain management (SCM). However, little scholarly attention has been paid to the transmission of CSR requirements from a small to medium-sized enterprises (SME) perspective. Drawing on institutional and innovation diffusion theories, this paper investigates to what extent the CSR requirements of customers influence the CSR activities of SMEs and their CSR requirements toward their own suppliers. Multiple mediation analysis was performed on data from a sample of 146,060 French SMEs. The findings indicate that the CSR requirements of customers have a direct negative effect on SMEs’ CSR requirements toward suppliers. However, the relationship becomes positive when we take into account the mediating role of the SMEs’ own CSR activities (i.e. economic, social and environmental activities). Furthermore, the study reveals that the indirect effect through economic CSR activities is the greatest, followed by social and then environmental CSR activities. Our main contribution is that implementing CSR activities within SMEs is a necessary step so that SMEs can be brokers in the transmission of CSR requirements in the supply chain.  相似文献
