Phase Transition of Dynamical Herd Behaviors in Financial Markets


  • Kyungsik Kim
  • Seong-Min Yoon


We study the phase transition of dynamical herd behaviors for the yen-dollar exchange rate in the Japanese financial market. It is obtained that the probability distribution of returns satisfies the power-law behavior with three different values of the scaling exponent 3.11 (one time lag $\tau$ = 1 minute), 2.81 (30 minutes), and 2.29 (1 hour). The crash regime in which the probabilty density increases with the increasing return appears in the case of $\tau$ 30 minutes. it is especially obtained that our dynamical herd behavior exhibits the phase transition at one time lag $\tau$ = 30 minutes.
