基于消费行为的中国奢侈品市场研究

中国已成为世界第二大奢侈品消费国。本文首先介绍了奢侈品的发展概况,接着从中国目前奢侈品消费市场的调研出发。分析了中国奢侈品市场的消费行为特点,最后对中国奢侈品市场的未来进行了展望。     

Second-party and third-party punishment in a public goods experiment

We experimentally investigate whether third-party punishment is more effective than second-party punishment to increase public goods contribution. In our experiment, third parties first played the standard public goods game and then made punishment decisions as independent bystanders. We find that third parties punished more frequently, severely and less antisocially, resulting in a higher contribution level than that driven by second-party punishment. The third party’s exaggerated emotion towards free riders is proposed to explain their superior punishment effectiveness.     

Finite-dimensional utilities

Summary. Sufficient axioms are identified for the existence of a finite- dimensional quasilinear utility function whose lexicographically ordered vectors preserve a decision maker's preference order on a mixture set . It is shown that those axioms are also necessary for the linear lexicographic representation when the underlying set is a mixture space.

Conditional ordering extensions

We produce a solution to the problem of extending a quasiordering conditional on a finite list of ex-ante comparisons between pairs. This constitutes yet another extension of the classical Szpilrajn’s theorem. Some examples of use of our result follow.     

Japanese Consumption,External Disequilibrium and their Statistical Measurement

Georgescu-Roegen's work is usually divided into two categories, his earlier work on consumer and production theory and his later concern with entropy and bioeconomics beginning with his 1966 introductory essay to his collected theoretical papers published in the volume Analytical Economics. Most economists usually praise his earlier work on pure theory and ignore his later work which is highly critical of neoclassical economics. Those economists sympathetic to his later work usually take the position that he “saw the light” and gave up neoclassical theory some time in the 1960s to turn his attention to the issues of resource scarcity and social institutions. It is argued here that there is an unbroken path running from Georgescu's work in pure theory in the 1930s, 1940s, and 1950s, through his writings on peasant economies in the 1960s, leading to his preoccupation with entropy and bioeconomics in the last 25 years of his life. That common thread is his preoccupation with “valuation.” The choices our species makes about resource use and the distribution of economic output depends upon our valuation framework. Georgescu-Roegen's work begins in the 1930s with a critical examination of the difficulties with the hedonistic valuation framework of neoclassical economics, moves in the 1960s to the conflict between social and hedonistic valuation, and culminates in the 1970s and 1980s with his examination of the conflict between individual, social, and environmental values. This paper traces the evolution of Georgescu-Roegen's thought about valuation and the environmental and social policy recommendations which arise out of his bioeconomic framework.     

Contracting with capacity constrained suppliers

This paper characterizes the optimal and efficient mechanisms to allocate simultaneously two substitute tasks to two suppliers. Two main results emerge from this analysis. First, even under some regularity conditions efficiency and optimality do not systematically coincide. Efficiency can always be achieved using some second price auctions which are optimal when both suppliers compete for the same task. When there is competition for different tasks the optimal production is distorted from efficiency over a nondegenerate interval of types so as to extract the full surplus over that interval. Second, full extraction of the surplus may still guarantee incentive compatibility. Received: November 2, 1998; revised version: March 2, 2000     

环境信息披露机制与企业发展——以日常耐用品生产企业为例

日常耐用消费品与人们的生活息息相关,其环保程度,对大众的身体健康有着重要影响。企业通过信息披露机制反映自身关于企业污染、治理方面的信息,可反映企业产品的环保程度,有利于消费者更好地了解企业,更好地反映产品的品质信息。企业披露高质量的环境信息,有利于建立良好的社会形象,有利于发展与消费者、政府间的互信机制,有利于强化企业产品的差异化程度,增强产品市场竞争力。
