Complex Dynamics in Nonlinear Triopoly Market with Different Expectations

Abstract EN

A dynamic triopoly game characterized by firms with different expectations is modeled by three-dimensional nonlinear difference equations, where the market has quadratic inverse demand function and the firm possesses cubic total cost function.

The local stability of Nash equilibrium is studied.

Numerical simulations are presented to show that the triopoly game model behaves chaotically with the variation of the parameters.

We obtain the fractal dimension of the strange attractor, bifurcation diagrams, and Lyapunov exponents of the system.
