Abstract:
According to a dynamic Cournot model, the dynamical game model on cost, sales volume and profits of corporations is analyzed under the conditions that demand function is non-linear and the cost function is linear. The stability of the equilibrium of the discrete dynamical system is studied. As some parameters of the model vary, the stability of Nash equilibrium would lose and the complex chaotic behavior occurs. Numerical results show that the player’s profits become more stable if the speed of adjustment decreases or variable cost per unit increases. Using reliable numerical methods, the complex dynamical behavior of the model are studied when two parameters are simultaneously varied. Several different routes to chaos can be found in iso-period plot and chaos plot.
