Study on the dynamic model of a duopoly game with delay in insurance market

چکیده
On the basis of domestic and foreign workers’ study, this paper considers the dynamic model of a duopoly price game in insurance market. In the duopoly model, we theoretically analyze the existence and stability of the Nash equilibrium point of the dynamic system, when one player or both players make a delayed decision, then stability conditions are obtained. The numerical simulation results further confirmed the accuracy of the theory. We observe that consideration of the delayed decision cannot change the equilibrium point of the system, but the time to the situation of stabilize will be changed because of the influence of the delayed variable and other parameters. If we increase the value of delayed parameter, the system will take longer time to be stable. If we change the speed of price adjustment and the weight of price of different periods, the time to the situation of stabilize will be changed. Key–Words: insurance market,duopoly,dynamic game,delayed decision

A game theory approach to the sawnwood and pulpwood markets in the north of Iran
Duopoly game theory is applied to the wood industrial markets (sawnwood and pulpwood markets) in the North of Iran. The Nash equilibrium and the dynamic properties of the system based on marginal adjustments are determined. The probability that the Nash equilibrium will be reached is almost zero. The dynamical properties of sawnwood and pulpwood prices derived via the duopoly game model are fou...

In this paper, the Bertrand's price competition in the retail duopoly with asymmetric costs is analyzed. Retailers sell substitute products in the framework of the classical economic order quantity (EOQ) model with linear demand function. The market potential and competitor price are considered to be the bifurcation parameters of retailers. Levels of the barriers to market penetration depending...

Dynamic game theory is applied to analyze the timber market in northern Iran as a duopsony. The Nash equilibrium and the dynamic properties of the system based on marginal adjustments are determined. When timber is sold, the different mills use mixed strategies to give sealed bids. It is found that the decision probability combination of the different mills follow a special form of attractor an...
متن کاملResearch on the triopoly dynamic game model based on different rationalities and its chaos control
Based on the earlier research results, and combined with the actual competition in Chinese insurance market, the triopoly dynamic game model is built under the hypothesis that the oligarchs make adaptive decision, delayed bounded rational decision and bounded rational decision respectively. The existence of only Nash equilibrium in the system is analyzed theoretically, and its stability and the...
