Figure 5

Simulation visualization for evolution of investor’s trading behavior in ER Network, WS Network, BA Network, and IN Network, respectively, when peer effect function is marginal utility increasing, based on the benchmark of behavior “buy.” (The Red, Blue and Green lines represent “buy,” “sell,” and “hold” when ⟨𝑘⟩=4. The Black, Pink Red, and Yellow lines represent “buy,” “sell,” and “hold” when ⟨𝑘⟩=12).
