Strong resonances and chaos in a stock market model

Abstract

A stock market model is considered, in which two classes of traders follow a time-invariant and a periodically varying feedback policy, respectively. A bifurcation analysis of the periodic solutions is carried out by means of a continuation technique. Attention is devoted to subharmonics, phase-locking and chaos. The latter is shown to emerge through a cascade of period doublings and torus destruction. The economic implications of chaos are examined.
