Risk Budgeting and Investment Structure Optimizing Models DU Ben-feng 2005, (3):  1-5.  Abstract ( 2021 )   PDF (678KB) ( 1643 )   Save Large investors, including plan sponsors,foundations,etc., face several difficulties in managing their assets.Some of the most perplexing relate to manager structure.Even though and asset allocation study directs investors to the most appropriate asset class structure,most investors have little to guide them in determining the manager structure that will put their money to work in the most effective way.We draw on the literature of active management related to building portfolios of securities,and adapt it to the problem of building portfolios of managers.

Moving Adjust Model of Margins in Futures Trade Based on GARCH-EWMA Model LIU Yi-fang, CHI Guo-tai, YU Fang-ping 2005, (3):  6-14.  Abstract ( 2286 )   PDF (2279KB) ( 1674 )   Save In this paper,based on the idea of EWMA model and GARCH model,combined the idea of SPAN system,using the important functions of the margin in the future markets as the consideration factors which remedy the largest loss in tomorrow and guarantee the trade running normally,making use of venture administering methods of symbolic statistics and VaR,we establish the moving adjust model of margin.Consequently,under the precondition of determined venture coefficient, decrease the rate of margin to the best of our abilities and offer new computing method for the determination of the future markets.The characteristics of this model are as follows:Firstly,we make use of the GARCH model of VaR method to determine the key parameter and attenuation factor of EWMA model, this will solve the problem to assign the decay factors by person causing the model with strong factors man-made. Secondly, introduce the fluctuation functions into the model, use them to confirm the fluctuation coefficient following the time "t", and adopt a lot of data of soybeans and soy meals contracts to fit the fluctuation functions,thus get the continuous function between the fluctuation functions and the time"t".This model can be used to replace the coarse functions used in Dalian Commodity Exchange.Thirdly,adopt nearly 4500 data of the history contracts, and give statistical analysis to the futures contracts of soybeans and soy meals to get the probability distribution of the limit up/down situation of the two types of contracts.Finally,comprehend each situation to get the final margins,thus make the model more comprehensive.

Behavioral Finance:Perceived Risk and Perceived Expected Return YANG Chun-peng, WU Chong-feng, CHEN min 2005, (3):  15-19.  Abstract ( 2199 )   PDF (1378KB) ( 1965 )   Save Under the frame of behavioral finance,this article established a model of perceived risk and a model of perceived expected return based on investor psychology in which over-confidence was taken into consideration,and further studied the relationship between perceived risk and perceived expected return.We showed that the negative correlation between perceived risk and perceived expected return which is contrary to the results in the standard finance theory.Through financial experiments,Shefrin(2001) found it is negatively correlated between perceived risk and perceived expected return.This article gave an effective explanation to the research of Shefrin(2001).

An Analysis of Competitive Telecom Network Interconnection LIAO Cheng-lin, LI Yi 2005, (3):  68-73.  Abstract ( 2082 )   PDF (1996KB) ( 1524 )   Save The competitive telecom network operators may refuse interconnection or may collude in levying high access price because of their own profit.The government’s regulation is necessary since both of the two kinds of conduct do harm consumers’ welfare.Using a three-stage game theory model containing Undercut-Proof Equilibrium mechanism and some contribution factors such as network externalities,dominant (operator’s) market share,market capacity,and users’ switch cost,this paper analyzes the issues of telecom network interconnection,including (service) pricing,connection decision-making,access price regulation,and welfare change.It is concluded that there exists a rational section of access price,in which the telecom network operators will have impetus to interconnect each other and welfare will be improved.

Resource Sharing Decision Model Based on Stackelberg Game in Collaborative Knowledge Creations WANG Jian-yu, FAN Zhi-ping, JIANG Yan-ping, HU Guo-dong 2005, (3):  84-88.  Abstract ( 2184 )   PDF (1409KB) ( 2431 )   Save For any collaborative endeavor to succeed,adequate allocation and sharing of resources are important in inter-organizational collaborative knowledge creation. The purpose of this paper is to explore the condition for resource sharing and maintaining collaboration in inter-organizational collaborative knowledgecreation. Firstly,using the game theoretic framework,the collaboration for knowledge creation is modeled as a Stackelberg leader-follower game with one leader and multi-follower. In this model,decisions are made at two stages. In the first stage,the leader sets the level of its involvement,which is called the participation rate,and in the next stage,the follower reacts to the leaders’ decision by setting an optimal value for the total efforts and respective participation rate. The equilibrium values of current efforts in knowledge creation,the leader and followers’ resource participation rate,and the total expected gain were then determined. Finally,it’s pointed out that maintaining an optimal ratio between the leader’s and followers’ marginal gains is important for the formation and continuation of the collaboration.

Study on Knowledge-Firms’ Incentive Based on Game Theory PAN An-cheng, HU Han-hui, ZHOU Ye 2005, (3):  108-114.  Abstract ( 2125 )   PDF (2405KB) ( 2283 )   Save Efficient incentive mechanisms can exert knowledge-employees’ more creativeness for the knowledge-firms.Under the conditions of the two-stage information asymmetry of value creation and value-addition distribution within the process of firms’sustainable growth,this paper analyzes the Stackelberg game between firm and knowledge-employee,and addresses the mechanism and value-addition distribution of the co-op game behavior in virtue of the evolutionary process of the fully co-op model.The result suggests that the short-run incentive is significantly complementary with the long-run one,and to adjust properly the level of the two can maximize the systematic income of the firm.How to allot firm systematic premiums is further researched,and it is argued that knowledge-employees’risk attitude and position significantly influence the incentive effort.
