![]() an increasingly slow response of the system to perturbations. Theoretical and empirical studies on climatic and ecological dynamical systems have shown that approach to tipping points is preceded by a generic phenomenon called critical slowing down, i.e. Fig O, Early warning signals of financial crashes for individual firms of DJI in 2008 and Cross-correlations.Ĭomplex systems inspired analysis suggests a hypothesis that financial meltdowns are abrupt critical transitions that occur when the system reaches a tipping point.

Fig K, Onset of strong trends of indicators roughly coincide across three stock markets. Fig I, Sensitivity analysis for the results of NASDAQ.
