九黄机场对九寨沟国内旅游者结构与行为的影响

九黄机场通航通过改变出行时间和感知距离等旅游决策要素来影响到旅游者结构与行为.对比通航前后九寨沟国内旅游者结构与行为各特征变化,表明九黄机场对游客空间结构、年龄构成、收入构成、居住环境、来源地构成以及出游目的构成等均造成了一定影响,而对文化程度、滞留时间和周边景点游览行为几乎没有影响.最后就分析结果进行讨论,提出了进一步完善九黄旅游网络结构的可能途径.     

构建高校"两课"教学新模式--运用网络教育与传统教育互补优势提高"两课"教学效果

在以科技为主导的21世纪，网络多媒体教学已成为教育领域新兴的重要教学模式，将网络教育引入到“两课”教学建设中，探讨二者的优势互补作用，对激发“两课”的活力，充分发挥“两课”对大学生进行思想政治教育的主渠道和主阵地的作用是十分必要的。

随着当前社会与经济的发展,对于石油等能源物质的需求量不断增加,石油在物流运输过程中所产生的成本也在不断提升。为降低我国石油物流运输工作过程中的成本,需要对当前石油物流的整体发展进行研究,并且基于此构建中国石油物流网络系统,从而使石油物流网络的整体运转效率得到提升并且降低成本。     

Are we nice(r) to nice(r) people?—An experimental analysis

We experimentally investigate whether individuals can reliably detect cooperators (the nice(r) people) in an anonymous decision environment involving “connected games.” Participants can condition their choices in an asymmetric prisoners’ dilemma and a trust game on past individual (their partner’s donation share to a self-selected charity) and social (whether their partner belongs to a group with high or low average donations) information. Thus, the two measures of niceness are the individual donation share in the donation task, and the cooperativeness of one’s choice in the two games. We find that high donors achieve a higher-than-average expected payoff by cooperating predominantly with other high donors. Group affiliation proved to be irrelevant.

The equilibrium set of two-player games with complementarities is a sublattice

Summary. I prove that the equilibrium set in a two-player game with complementarities, and totally ordered strategy spaces, is a sublattice of the joint strategy space. Received: May 31, 2001; revised version: October 4, 2002     

A strategic market game with seigniorage costs of Fiat money

Summary. A model that includes the cost of producing money is presented and the nature of the inefficient equilibria in the model are examined. It is suggested that if one acknowledges that transactions are a form of production, which requires the consumption of resources, then the concept of Pareto optimality is inappropriate for assessing efficiency. Instead it becomes necessary to provide an appropriate comparative analysis of alternative transactions mechanisms in the appropriate context.

从广西看大西南出海通道建设

广西在大西南出海通道的建设中占有极其重要的地位，本文采用网络模型，按现状与规划路网两种情况，综合考虑陆上距离和去不同方向市场的海上距离，分析了北海（代表广西港口群）、湛江、广州等三条出海通道的三个港。各自的吸引范围。并由此得出了一些有益的结论。     

Strategic freedom, constraint, and symmetry in one-period markets with cash and credit payment

Summary. In order to explain in a systematic way why certain combinations of market, financial, and legal structures may be intrinsic to certain capabilities to exchange real goods, we introduce criteria for abstracting the qualitative functions of markets. The criteria involve the number of strategic freedoms the combined institutions, considered as formalized strategic games, present to traders, the constraints they impose, and the symmetry with which those constraints are applied to the traders. We pay particular attention to what is required to make these strategic market games well-defined, and to make various solutions computable by the agents within the bounds on information and control they are assumed to have. As an application of these criteria, we present a complete taxonomy of the minimal one-period exchange economies with symmetric information and inside money. A natural hierarchy of market forms is observed to emerge, in which institutionally simpler markets are often found to be more suitable to fewer and less-diversified traders, while the institutionally richer markets only become functional as the size and diversity of their users gets large.Received: 5 June 2003, Revised: 18 November 2003, JEL Classification Numbers: C7, G10, G20, L10, D40, D50.
