关于收益法的经济价值论及其基础之研究

收益法是资产评估中最基本的一种方法,本文对资本价值理论及其价值论基础--效用论、边际效用论以及理论应 用(收益法)进行全面系统的研究。     

城市空间扩张与土地集约利用

我国自1996年已经进入城市化快速发展时期,城市化快速发展使得大量农村人口涌入城市,经济总量的提升加速城市空间的扩大,大量占用非城市建设用地,而现有自然承载力的限制使得城市化快速发展与城市空间的扩张对土地集约利用提出了更深层次的要求。文章构建了城市化与土地集约利用模型,分析动态城市化对不同行为主体的影响,提出低成本、集约型城市化模式概念,以推动和促进我国城市经济的健康、科学发展,构建社会主义和谐社会。     

非期望效用理论研究述评

期望效用理论（EUT）出现后,成为主流经济学和管理学中研究不确定性环境下决策活动的理论基础。但近50年特别是最近20多年来,随着行为科学的发展以及实验经济学的崛起且逐步融入主流,与EUT相抵触的经验证据大量涌现,因此其作为不确定性决策活动的理论根基正在被广泛质疑,各学科寻找EUT替代者的努力催生了多种不同的非期望效用理论。本文在对经典期望效用理论批判的基础上,对国外正处于进展中的非期望效用理论文献进行全面回顾和简单评价,以期为国内从事这一领域理论和应用研究的学者提供一些线索和思路。     

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     

托达罗人口流动模型的改进——基于风险升水的视角

农村劳动力的迁移决策是一个理性的经济决策行为,迁移者在做出迁移决策时不仅仅要考虑预期的城乡收入差异,理性的迁移者还会考虑到不确定性带来的效用损失,文章用一个风险升水值来度量这种效用损失,并认为应该从托达罗模型的预期收入差异中剔除这个损失额度。因而,实际预期的城乡收入差异会比托达罗模型所表述的更小,一些风险规避的迁移者可能就会因此退出迁移。     

Etzioni versus Becker: Do Moral Sentiments differ from Ordinary Tastes?

There are two competing definitions of economics. One, exemplified in Etzioni's work, stipulates that economics is the study of one kind of ends, the pursuit of material benefits (welfare). This definition entails that material ends are incommensurable with moral ends. The other, expressed in Becker's work, registers that economics is the analysis of one aspect of all ends, optimization. This definition implies that material and moral ends are commensurable. The paper finds that each definition has its own shortcomings. The paper outlines an alternative view, illustrated by the difference between gifts and grants, which promises to supplant the shortcomings of each definition.
