The model of public policy studied in this paper has heterogeneous citizens/voters and two public goods: one (roads) chosen directly by an elected policy‐maker, and the other (pollution) stochastically dependent on the amount of roads. Both a one‐country and a two‐country version of the model are analyzed; the latter displays externalities across the countries which create incentives for free riding and strategic delegation. The welfare effects of providing the policy‐maker with information about the relationship between roads and pollution are investigated, and it is shown that more information hurts some—sometimes even all—citizens. In particular, the opportunity not to create an institution for information gathering can serve as a commitment device for a country, although with the unfortunate effect of making the overall outcome even worse. Implications for the welfare effects of “informational lobbying” are also discussed.  相似文献

The principal aim of this paper is to evaluate the impact of the future European high-speed train network on accessibility, by reducing time distance between places and modifying their relative location. We compare the current situation with that foreseen for the year 2010, according to the Outline Plan of the European High-Speed Train Network, in order to analyse which areas will most benefit from construction and improvement of the infrastructure. It is hypothesized that the high-speed train will certainly bring the peripheral regions closer to the central ones, but will also increase imbalances between the main cities and their hinterlands. A weighted average distance indicator is applied for this purpose. This measure identifies the spatial distribution of accessibility in the area of study, emphasizing the infrastructure effects, and locates accessibility changes at the European level. A Geographic Information System (GIS) has been used to carry out this study.  相似文献

Graphical models provide a powerful and flexible approach to the analysis of complex problems in genetics. While task-specific software may be extremely efficient for any particular analysis, it is often difficult to adapt to new computational challenges. By viewing these genetic applications in a more general framework, many problems can be handled by essentially the same software. This is advantageous in an area where fast methodological development is essential. Once a method has been fully developed and tested, problem-specific software may then be required. The aim of this paper is to illustrate the potential use of a graphical model approach to genetic analyses by taking a very simple and well-understood problem by way of example.  相似文献

企业评价创新——从绩效评估到基于战略聚焦的价值管理   总被引:2,自引:0,他引:2  
侯梅  李文 《价值工程》2004,23(4):16-18
新经济时代的企业环境促使企业管理战略发生了巨大变化,同时又为企业组织与运营模式的创新提供了先进手段。在这种环境下,传统绩效评价模式呈现出诸多方面的缺陷和不适,因此必然要求相应的改变。本文分析了企业绩效评价的研究现状,探讨绩效管理的发展趋势,最后就两种面向战略聚焦的价值管理模式进行评述。  相似文献

上海都市旅游规划的时空审视及其战略取向   总被引:1,自引:0,他引:1  
庄志民 《旅游学刊》2007,22(4):43-47
时间和空间是物质存在的方式,也是旅游活动存在的方式.脱离了时间的空间,或者脱离了空间的时间,在实际上都是不可能存在的.针对上海城市对空间的重视程度高于对时间的关注之倾向,本文立足于二元一体的时空坐标,从辩证思维视角,对上海都市旅游作属性定位,提出了上海都市旅游的战略选择取向应当立足于"通过空间展示时间"的观点,进而在时空坐标战略钟的选择中,提出上海城市建设以及都市旅游发展战略选择的合理取向的某些构想.  相似文献

This paper is about the study of purchasing cooperation with the supplier. It is through expanding some courses including demand analysis, choosing supplier, founding cooperation relationship formally and strengthening the cooperation, as well as several key questions, such as sourcing strategy, to estimate and select the supplier, authentication management, and purchase of technology.  相似文献

This paper analyses governance structures used to organize partnerships in R&D networks using two approaches: transaction costs theory and social capital theory. We argue that these theories are complementary; this explains forms of governance through the degrees of administrative (structural and safeguard mechanism) and social factors (cohesion and openness) they embody. Data was obtained from European R&D networks created through Framework Programmes which include a great number of universities, non profit institutions and firms. Findings show the variables that characterize and explain the governance forms based on the applicability of R&D networks. This study not only provides a theoretical model for analysing governance structures of these networks, but is also useful for both improving the management of networks and for fostering collaboration at an international level.  相似文献

This article critiques the efforts by Janet Landa, David Sloan Wilson and others to use group selection paradigms to explain the success of homogenous middlemen groups (HMGs). It argues that group selection theory cannot explain the conflicts of interests that arise within HMGs or why they dissolve in certain occasions. Landa’s earlier explanations, which stressed the combination of genetic (kinship) and social bonds in the creation of trust and cooperation in the extension of credit and the creation of local public goods, better predicts both the strength and weaknesses of HMGs.   相似文献
