Abstract

In the fi rst part of our paper we proposed a three-dimensional nonlinear dynamic model of interacting stock and foreign exchange markets, jointly driven by the speculative activity of heterogeneous investors. We focused, in particular, on the typical 'bull and bear' scenario that emerges from simpli ed one- and two-dimensional settings. The goal of this part of the paper is to provide a global analysis of the dynamics of the full model. As it turns out, the results we obtained in the fi rst part may serve as a road map to develop an initial understanding of the much more complicated three-dimensional model.
