The Measurement of Consumption Efficiency Considering the Discrete Choice of Consumers

In this study we propose a mathematical definition of the consumption efficiency of multi-attribute products in the price–quality space. A new model, the discrete Range Adjusted Measure (RAM) model, is suggested as an empirical tool to measure the level of consumption efficiency. We further discuss the effect of consumption efficiency on the innovation incentive. Empirical work is made for the mobile phone market. We expect that the consumption efficiency concept will contribute to the extension of the traditional framework of production efficiency analysis on the one hand and to the understanding of the nature of innovation in a technology-intensive market on the other hand.JEL Classification: C67, D11, D12, D21

基于价值工程理论的房地产性价比确定

高性价比已成为房地产开发商和消费者共同追求的目标,然而长期以来性价比都只是定性描述。本文建立了房地产性能评价指标体系,并应用价值工程理论构建了房地产性价比的确定模型,将其定量化,最后通过一个案例进行了说明。     

The housing question in Japan

This article first examines how bad housing conditions are in Japan based on international comparisons. The next question is whether the extremely high land prices in Japan can be explained by economic logic. We then turn to more specific housing policy questions that are peculiar to or important in Japan, such as the tax advantages of owning land that have caused under-utilization of land and the reasons why the average size of Japanese rental housing is so small.     

一种新的顾客满意度指数测评模型

顾客满意度指数是近年来许多国家和地区积极开展研究和采用的一种新的经济指标。本文在已有研究的基础上,结合我国消费者行为的特点,构建了一种新的顾客满意度指数测评模型。该模型在期望不一致模式的基础上,同时考虑了公平模式和需要不一致模式,引入感知公平和感知价格变量,并为这些结构变量设计了相应的观测变量和路径关系,建立了由顾客满意、企业形象、感知价格到顾客忠诚三条路径关系,改变了传统模型中从顾客满意到顾客忠诚路径过于单一的情况。

Outsourcing and trade in a spatial world

This paper provides an analysis of outsourcing and trade in a spatial model à la Hotelling. In this setting, we discuss the trade-off between transport-cost-related disadvantages and outsourcing-related production cost advantages of a large economy and we investigate how the existence of national transport costs influences both the structure of industrial production and the pattern of final goods trade. In addition, the model gives a rich picture of the possible welfare effects of trade liberalization. In particular, we show that a final goods exporting country definitely gains from economic integration, while a final goods importing country may lose. Finally, when lowering domestic outsourcing activities, trade liberalization may reduce world welfare, even if pro-competitive effects lead to a decline in consumer prices.     

企业推广排污权交易的可行性研究

排污权交易(Ernission trading)是一种基于市场(Market-based)的环境政策。本文坚持以科学的发展观，来研究经济发展与环境保护的协调关系，目的是实现环境资源和环境容量的可持续利用。本文分析了企业的排污行为决策，并将环境资源和环境容量的稀缺性纳入排污权交易价格之中。通过价格这个经济杠杆去调节人们对环境资源和环境容量的利用，反映于企业为其排污行为所作的选择，进而论述企业推进排污权交易的可行性。     

Blocked-Error-R 2: A Conceptually Improved Definition of the Proportion of Explained Variance in Models Containing Loops or Correlated Residuals

Bentler and Raykov (2000, Journal of Applied Psychology 85: 125–131), and Jöreskog (1999a, http://www.ssicentral.com/lisrel/column3.htm, 1999b http://www.ssicentral. com/lisrel/column5.htm) proposed procedures for calculating R ² for dependent variables involved in loops or possessing correlated errors. This article demonstrates that Bentler and Raykov’s procedure can not be routinely interpreted as a “proportion” of explained variance, while Jöreskog’s reduced-form calculation is unnecessarily restrictive. The new blocked-error-R ² (beR ²) uses a minimal hypothetical causal intervention to resolve the variance-partitioning ambiguities created by loops and correlated errors. Hayduk (1996) discussed how stabilising feedback models – models capable of counteracting external perturbations – can result in an acceptable error variance which exceeds the variance of the dependent variable to which that error is attached. For variables included within loops, whether stabilising or not, beR ² provides the same value as Hayduk’s (1996) loop-adjusted-R ². For variables not involved in loops and not displaying correlated residuals, beR ² reports the same value as the traditional regression R ². Thus, beR ² provides a conceptualisation of the proportion of explained variance that spans both recursive and nonrecursive structural equation models. A procedure for calculating beR ² in any SEM program is provided.     

企业资产结构的影响因素及模式研究

资产结构是指企业资本在不同资产形态上分布状况及分配比例。资产结构一般具有整体性、封闭性、动态性等特征;资产结构的形成受到诸多内外部因素的影响。本文研究了影响企业资产结构的因素,分析了资产结构的类型,并根据资产变现性的特征,将资产结构模式分为三种类型。
