0-1 test for chaos in a fractional order financial system with investment incentive

Abstract

A new integer-order chaotic financial system is extended by introducing a simple investment incentive into a three-dimensional chaotic financial system. A four-dimensional fractional-order chaotic financial system is presented by bringing fractional calculus into the new integer-order financial system. By using weighted integral thought, the fractional order derivative's economics meaning is given. The 0-1 test algorithm and the improved Adams-Bashforth- Moulton predictor-corrector scheme are employed to detect numerically the chaos in the proposed fractional order financial system. © 2013 Baogui Xin and Yuting Li.
