A Study on the Zero-Level Approach to Assets Pricing in Incomplete Markets CHEN Jin-long 2004, (2):  1-5.  Abstract ( 1817 )   PDF (2171KB) ( 1532 )   Save The approach of zero-level pricing of a nonmarketed asset is to find the price such that a certain investor with special utility function and wealth will select the new asset included in his optimal portfolio at the zero-level.In other words,the optimal portfolio would not change at the price when the new asset presents.In this paper,the idea and characters of zero-level pricing will be introduced,which were presented by Lenberger and other researchers.After comparing this approach with e-arbitrage methods,we point out that the two approaches are the same under the condition of partially complete markets.

A Real Option Pricing Model Based on Information Entropy Theory CAI Jian-xue, QIU Wan-hua 2004, (2):  22-26.  Abstract ( 2035 )   PDF (848KB) ( 2491 )   Save This paper presents a real option pricing model based on information-theory. It depends on historical data and investor’s experience to estimate the option price of a project or production,as a result it avoids the problem caused by traditional option pricing models which heavily rely on the choice of parameters and many assumptions.Furthermore,in this paper,the author also discusses the relationship between this model and the traditional option pricing model,and reasonably explains the importance of information in the investment decision Finally,the applicaition value of this model is illustrated by using an example.

Design of the Raw Material Industrial Index and Study of Its Funtions Luo Xiao-ling, Zhang Yang 2004, (2):  27-31.  Abstract ( 2017 )   PDF (837KB) ( 2227 )   Save Commodities futures index,first as an economic indicator,second as a financial derivative tool,it is helpful for government department,investor and investigator to hold and grasp commodity price.Therefore,we bring forward the index compilation method according with the real condition of China and figure out the raw material industrial index.The conclusings have drawn,the Chinas raw material industrial index circulates normally,the Granger causality is existing from China’s raw material industrial index to PPI,the former leads the latter by three months.Since the China’s raw material industrial index reflects the price fluctuations of raw material industrial products,it could be a indicator to monitor the industrial boom of our country.Ultimately,the author suggests that the government administration should put the raw material industrial index into the Shanghai Futures Exchange as a financial derivative investable tool with a feasible plan.

Market Share Research Based on Customer Orientation HUANG Jin-song, ZHAO Ping, WANG Gao, LU Qi-bin 2004, (2):  95-101.  Abstract ( 2327 )   PDF (1526KB) ( 1886 )   Save Market share is one of the most important aspects that companies pay their attention to. However, Chinese companies always tend to lower the price of their products in order to increase market share. In this article, we firstly describe the effects of customer satisfaction, customer loyalty and price that exert on market share in terms of customer satisfaction theory. Where after, we carry out an experiential analysis by using data of seven Chinese family electric appliances industries and draw following conclusions: Price exerts some influences on market share, but the pivotal factors of increasing market share are improving customer loyalty, customer satisfaction, customer brand image perception and customer product and service perception.

An Iterated Model on the Degree of Willingness to Cooperate Based on Member Characteristic and History Information YE Hong-xin, XUE Yao-wen, SHENG Zhao-han 2004, (2):  102-107.  Abstract ( 2164 )   PDF (1438KB) ( 1587 )   Save In this paper, we above all present the concept of the degree of willingness to cooperate (DWC) based on relative game-theoretic concept from viewpoint of psychology. On the base of the consideration of member characteristic and history information, we build up DWC model on dynamic evolution of group, which surmounts the localization of the neglect of history information, group member characteristic, and their desire and of the absence of initiative interpretation about cooperation-competition-conflict. By that we open out the process of strategy adjustment and interaction of group member before attain equilibrium. In order to show its value in application, we engage in simulation study on DWC model involved with circumstance and continency and givea detail analysis about simulation result.

The Influence of the Delayed Decision on the Dynamical Evolution of a Production System LI Yu, SHENG Zhao-han, CHEN Guo-hua 2004, (2):  118-123.  Abstract ( 1814 )   PDF (1175KB) ( 1314 )   Save firms are bounded rationally in the market.So they make production decisions not only based on the marginal profit of current period but on the marginal profits of many continuous periods.The paper studies the influence of the delay on the system and finds that the stable region of Nash equilibrium is enlarged,which offers a realistic way to realize the control of the period doubling bifurcations.Meanwhile,when two parameters,adjusting speed and weighted factor,satisfy certain conditions,other complicated dynamical behaviors such as Hopf bifurcation will occur at the Nash equilibrium.Delayed decision rule can improve the system performance and has great influence on the market competition.
