*/a Dynamical Systems Approach"/*

*/Abstract/*
//
/We build a multi-agent dynamical system for the global economy to
investigate and analyze financial crises. The agents are large
aggregates of a subeconomy, and the global economy is a collection of
subeconomies. We use well-known theories of dynamical systems to
represent a financial crisis as propagation of a negative shock on
wealth due the breakage of a financial equilibrium. We first extend the
frameworkof the market instability indicator, an early warning signal
defined for a single economy as the spectral radius of the Jacobian
matrix of the wealth dynamical system. Then, we formulatea quantitative
definition of instability contagion in terms thereof. Finally, we
analyze the mechanism of instability contagion for both single and
multiple economies. Our contribution is to provide a methodology to
quantify and monitor the level of instability insectors and stages of a
structured global economic model and how it may propagatebetween its
components./
