隐藏“网上邻居”中的共享文件夹

在局域网中共享文件夹的时候，可能会遇到这种情况。一方面不想让别人通过局域网内别的电脑查看到你共享的文件夹，另一方面又不得不共享这些文件夹以便同事或自已在别的电脑上调用其中的文件，两全其美的办法就是在局域网中隐藏这个共享文件夹，然后在其他机器上直接访问它。

Pareto optimal redistribution and private charity

When private charity exists and is motivated by utility interdependence a non-Pareto optimal outcome, the ‘free-rider’ problem, typically arises. Nevertheless, incremental fiscal redistribution cannot achieve a Paretian welfare improvement so long as private charity continues at positive levels. Donors respond to incremental fiscal redistribution by reducing their voluntary contributions by exactly a dollar for every dollar transferred in this way. No net transfer is achieved unless incremental fiscal redistribution is pursued to the point where private contributions have been driven to zero. Alternatively, a net transfer may be achieved by fiscal measures which affect donors' marginal incentives to donate.     

Regulation of State-Owned and Privatized Utilities: Ukraine Electricity Distribution Company Performance*

Both ownership and regulation affect the behavior of utility managers. Private ownership rewards managerial decisions that enhance shareholder value. Regulatory incentives reward behavior that affects profits and costs. An empirical analysis of 24 Ukraine electricity distribution companies from 1998 to 2002 indicates that privately owned firms do respond to incentives that add to net cash flows (associated with reducing commercial and non-commercial network losses). However, they also respond more aggressively than do state-owned distribution utilities to mark-up (cost-plus) regulatory incentives that increase shareholder value but decrease cost efficiency. This study was initiated while Val Tsaplin was a PURC Visiting Scholar with funding from the FSA Contemporary Issues Fellowship Program. Michael Pollitt, David Sappington, Fernando Damonte, and an unknown reviewer provided very helpful comments on earlier drafts. We thank Patricia Mason for copy-editing the paper.

企业信息化网络构架的选择

在信息社会里,信息化是各行各业发展的必经之路,而企业在信息化中面对的首要问题就是实现信息化的基础构架,即网络结构的选择。目前,企业根据信息化的不同阶段和用途可以选择的网络结构有：Intranet（企业内部网）、Extranet（企业外联网）、Internet（国际互联网）,通过对不同网络结构特点的分析,指出了企业对三种网络构架的选择方法。     

Transboundary air pollution and soil acidification: A dynamic analysis of an acid rain game between Finland and the USSR

Transboundary air pollution is analysed as a dynamic game between Finland and the nearby areas of the Soviet Union. Sulphur emissions are used as the environmental control variables and the acidities of the soils as the state variables. Acidification is consequently considered to be a stock pollutant having long-lasting harmful effects on the environment. The state dynamics consist of two relationships: first, of a sulphur transportation model between the regions and, second, of a model describing how the quality of the soil is affected by sulphur deposition. The countries are assumed to be interested in maximizing the net benefits from pollution control as measured by the impacts on the values of forest growth net of the abatement costs. Cooperative and noncooperative solutions of the game are compared to assess the benefits of bilateral cooperation. Using empirical estimates of abatement costs, acidification dynamics and impacts on forest growth it is shown that cooperation is beneficial to Finland but not to the Soviet Union. Consequently, Finland has to offer monetary compensation to induce her neighbor to invest in environmental protection.

ENDOGENOUS CONSUMER PARTICIPATION AND THE RECYCLING PROBLEM*

We endogenise the extent of consumer participation in the recycling process, and analyse its effect on the ‘recycling problem’. When recycling requires consumers to undertake costly sorting activities to separate scrap from household waste, they will participate only if the net reward from sorting is positive. Consumers' sorting cost is subject to a network effect arising due to social norms. With heterogeneous consumers differing in terms of their sorting cost, the entire output of the recyclable product may not be subsequently available as scrap to the recycling firms. This increases the virgin producer's monopoly power, and may also lead to multiple equilibria if the network effect of sorting is sufficiently large. The latter result suggests a role for the government in influencing equilibrium selection to improve social welfare. Depending on the fraction of consumers that participate in recycling, increased societal pressure on consumers to recycle may decrease consumer participation and increase the virgin producer's market power.     

人民币汇率对我国对外贸易结构的影响分析

作者利用贸易特定化系数衡量了我国2005年7月21日人民币汇率形成机制改革之后的对外贸易结构，结果显示随着人民币汇率的爬行式缓慢升值，我国大部分资源密集型商品的净出口减少，劳动密集型商品和资本、技术密集型商品的净出口增加，竞争力增强，进出口商品的贸易结构得到优化。因此，进一步完善人民币汇率形成机制，推动人民币汇率稳步升值对我国进出口商品贸易结构是长期利好的。     

Efficiency in International Trade with Firm Heterogeneity and Networks

This paper examines integrated effects of firm heterogeneity and communication network services on international trade. Patterns and effects of trade are analyzed in a general equilibrium model where firms with different productivity levels share among them the cost of network services and compete in a monopolistically competitive market for a differentiated good. The paper reveals that the more efficient country in the production of the differentiated good is not always the net exporter of the good. The less efficient country also has the chance to expand the industry and then to become the net exporter in this intra‐industry trade due to the combination of the efficiency effect induced by firm heterogeneity and the cost‐sharing effect by the existence of the network service industry.     

中国可持续发展水平区域差异的人工神经网络判定

本文在对目前区域可持续发展水平度量方法进行分析的基础上,提出以人工神经网络(ANN)作为区分中国可持续发展水平区域差异的模型工具。构建了ANN模型分析中较为先进的自组织特征映射网络(Self-Organizing Maps,SOFM),并以中国31个省市(自治区)1996年的社会、经济、资源和环境状况作为待分样本,用SOFM进行了可持续发展区域差异的判定。网络运行结果表明,1996年中国可持续发展水平的区域差异可分成5类,SOFM分类结果与专家的判断基本近似。可见,人工神经网络是一条具有发展和应用前景的途径。
