Abstract:Based on the concept of willingness to cooperate(DWC),the paper construct the normal condition DWC model for infinite cooperating games.The aim is to study 2 problems: how the player is perception style will influence the rate of payoff and how accident environment will affect player's DWC.After studying the 2-people infinite repetition games,we find that the flexible-thinking player could acquire less DWC and rate of payoff than rigidity-thinking player;the ahead-thinking player may not get high rate of pa...

Abstract:Karotkin et al discovered that sets of weighted majority rules possess a property of essential order.However,they didn't explain the reason of that. In this paper,we proposed the concept of decision-rule chain and distance function of decision rules,and pointed out that when a set of decision rules compose a decision-rule chain they possess the property of essential order.Therefore the property of essential order is explained.And we can examine whether a set of decision rules compose a decision-rule chain b...

Abstract:In the course of decision group meta-synthetic argumentation, it is necessary to analyze and design the attributes, the structure and the relationships of argument information strictly, to explore new visual technology of group argument information. This paper designs a new visual organizing and revealing of argument information to adapt to the group dynamic communication. The semantic relationships between different speeches are classified as supporting, opposing, querying, supplying and correlating. Accor...

Abstract:By the WTO(World Trade Organization) Safeguard Rules, turn it into three stage dynamic games model,and compare and discuss mainly the difference of safeguard against one country and two countries at the same time.In the objection of industry interests maximization and social welfare maximization,the paper discuss the influence of safeguard to complaint country and target countries,and the request of WTO safeguard regular and the effect of anti-retaliate instead, if safeguard be to implemented abuse,and be v...

Abstract:Under the background of China mobile's MMS service,supply chain cooperation mechanism of Mobile Internet is investigated in this paper.It is found that with certain market demand,when mobile internet operator and service provider collaborate and make decisions of network construction scale and product's sale price together,then as a result of the revenue-sharing contract,supply chain profit can be maximized and coordination of mobile internet can be realized.

Abstract:In order to gain either price discount or the transportation convenience,bath-ordering is also are required by manufacturer. In this paper,the optimal retailer batch-ordering policy for perishable with demand information updating is studied.The supply chain gains co-win for both manufacturer and retailer via the manufacturer providing two ordering chances for the retailer.Based on the models for the system at the beginning time and after the demand information updating,some analysis and discuss are processe...

Abstract:This paper studies the term structure of 7-,30-,60-day China interbank offered rates(CHIBOR) using weekly data spanning 1996-1-1—2003-7-21.One interesting finding is that there exists a structural change on the China interbank offered rates during the sample period.The expectation hypothesis(EH) is supported by data prior to the Asia financial crisis.But expectation hypothesis is soundly rejected by data after the Asia financial crisis.

Abstract:This paper studies the optimal investment strategies of maximizing expected utility from terminal wealth.According to the fact that the borrowing rate is higher than the saving rate,and by adoption of the utility function of U(x)=x~ρ/ρ,0<ρ<1 for the investor,we develop a new method of Guess-Verify instead of stochastic dynamic programming with It formula and nonlinear programming technique to solve the optimal investment strategies,which is easy to handle.

Abstract:Based on the Partial Distribution and the Partial Process,this paper presents the DF structure of strike price of option for the first time,and gives the DF structure pricing models,the constructive analytic models for options pricing on a non-dividend-paying stock.The models can be used in the pricing of both call options and the put options exercised at any time before the expiration.Hence,they are applicable to the pricing the American call and put option the European call and put options.The final empir...

Abstract:Based on the arguments of the theory of Value-based Leadership(VBL) and the preliminary conclusions derived from a leadership project that was conducted in China in the past three years,the paper proposed a new theoretical model in which the environmental factors were included to examine the dynamic relationship between the VBL behaviors and leadership effectiveness.Results show that the VBL behaviors help improve leadership effectiveness when the company faces intense external competitions although those a...

Abstract:As a powerful tool in dealing with uncertainty questions,the evidence using in the evidence theory is given by experts.The expert's knowledge is limited,subjective and sometimes difficult to obtain.To solve these problems,this paper proposes a new method of knowledge acquirement and presents a method of evidence combination and application.Firstly,we research the problem of how to partition the huge decision table.By analysing of the dependency degree among the attributes based on the Rough Sets(RS),conditi...

Abstract:In this paper conclusion of Koopman et al(2002) has been tested using SV-m model.Then,SV-m model is extended and A-SV-m model is proposed,which can catch asymmetry information effect.Boot the old SV-m model and A-SV-m model are used in empirical studies on the relationship between expected returns and volatility.Results are different from Koopman's conclusion and show that the relationship between expected returns and volatility is time varying,and the effect the volatility has on the expected retruns is in...

Abstract:This paper reviews the new development of psychological contract research in China and abroad at five aspects as following: the emergence and development of psychological contract concept,the structure and development of psychological contract,the boundaries between psychological contract and other correlative concepts,the formation and fashions of psychological contract,the violation and consequence of psychological contract.Finally,the deficiencies of current research are pointed out.They are: lack of res...

Abstract:A new data envelopment analysis(max-min DEA) model is proposed by maximizing the efficiency of the minimal efficiency Units.The idea combing selfrated and other-rated schema is adopted in the proposed model.Thus,to some extent,two inter-related problems that are weak discriminating power and unrealistic weight distribution occurred in classical DEA are solved.In this model,efficiency criteria more restrictive than the classical one will yield fewer efficient DMUs and will allow less flexibility for input/ou...
