我国服务业增加值的核算问题

本文集中讨论我国服务业增加值估算中存在的问题。由于历史原因和服务业本身的一些特点 ,我国现价服务业增加值被严重地低估了 ,服务业增长率计算也可能存在着偏差。对服务业增加值的以往研究均受到基础数据的限制而未能根本地解决这些问题。服务业统计核算的缺陷严重地阻碍着经济分析和经济决策。因此 ,改善我国服务业统计核算是当务之急。从长远的角度来说 ,服务业增加值核算的改善在很大程度上取决于统计调查的完善。但是 ,在现有的条件下 ,仍然有很大的改善余地。

我国海洋养殖资源资产流失量价值模型构建

海洋养殖资源资产的流失已成为制约养殖业发展的重要因素之一。本文通过对养殖资源及养殖资源资产流失的界定,在资源所有者的所有权受损和海域低效利用基础上提出流失量价值即为海洋养殖资源资产价值与国家养殖资源资产总收益的差值,并将海水资源价值、环境成本价值和养殖成本价值作为养殖资源资产的总价值。     

中国航空货运顾客价值动因的实证研究

通过考察中国航空货运,建立航空顾客价值的决定因素与动态性理论模型,运用结构方程方法对其检验,结果表明:时间因素和便捷性因素是影响货运顾客价值的核心要素,价格因素已退之其次,而且来自竞争者、服务商、顾客、宏观环境的变化都对顾客价值动态性有显著影响。     

Review of tourism resources valuation

Tourism resources valuation is now a hot issue of the science of tourism resources, resources economics and environmental economics. This paper reviews research progresss on tourism resources valuation, introduces its theoretic basis, and elaborates two classical valuation methods： TCM and CVM. And two existing problems are discussed Firstly, tourism resources value constitution system is still under dispute. This paper puts forward the Value constitution system based on present value categories. Secondly, tourism resources valuation methods need further studies because both TCM and CVM have deficiencies. Finally, the paper points out the development direction of tourism resources valuation.     

论第三方物流的经济性

第三方物流是一种专业化的物流组织，具有很强的经济性。随着第三方物流的发展，它的经济性会发挥的更加充分。第三方物流的经济性，主要包括规模经济性，价值创新性和外部经济性。规模经济性是它的基本特征，价值创新性是它的功能特性，而外部经济性则是它的社会效益的表现。全面理解第三方物流的经济性，有利于企业进行科学的物流决策，有利于政府制定有效的物流发展战略。     

The measurement and decomposition of nonuse values: A critical review

We critically review the literature that claims that existence values, or nonuse values in general, are a large and measurable component of total value for certain environmental resources. Our concern is not with the question “do nonuse values exist?” For some individuals they surely do. Rather, our concern is with two interrelated questions: are there operationally meaningful theorems which might lead to the specific measurement of nonuse values, and do we in fact have a body of credible evidence which shows that nonuse values, particularly components of any nonuse value, are “large”? We find nothing in the way of operationally meaningful hypotheses which would permit the estimation of values attributable to specific motives of individuals. We find no credible basis for claims related to either the measurement of existence and other motive-related values or claims for the “large” relative size of such values. In short, we question the conventional wisdom that such values are measurable and that they are significant as a component of total value.

Price discrimination and efficient matching

This paper considers the problem of a monopoly matchmaker that uses a schedule of entrance fees to sort different types of agents on the two sides of a matching market into exclusive meeting places, where agents randomly form pairwise matches. We make the standard assumption that the match value function exhibits complementarities, so that matching types at equal percentiles maximizes total match value and is efficient. We provide necessary conditions and sufficient conditions for the revenue-maximizing sorting to be efficient. These conditions require the match value function, modified to incorporate the incentive cost of eliciting private type information, to exhibit complementarities in types.JEL Clalssification Numbers C7, D4We thank Jonathan Levin, Tracy Lewis, and the seminar audience at University of California at Los Angeles, University of British Columbia, Duke University, and 2003 Econometric Society North American Summer Meeting for comments and suggestions.

Component efficient solutions in line-graph games with applications

Recently, applications of cooperative game theory to economic allocation problems have gained popularity. We investigate a class of cooperative games that generalizes some economic applications with a similar structure. These are the so-called line-graph games being cooperative TU-games in which the players are linearly ordered. Examples of situations that can be modeled like this are sequencing situations and water distribution problems. We define four properties with respect to deleting edges that each selects a unique component efficient solution on the class of line-graph games. We interpret these solutions and properties in terms of dividend distributions, and apply them to economic situations.
