**概要 [#id7b43a9]
Various preceding market models can reproduce basic financial stylized facts such as volatility clustering, but most of those models require strict tuning of parameters for the reproduction. Inspired by the idea of the sandpile model, we present a simple agent-based model of the financial market named Self-organized Speculation Game, where the number of traders is spontaneously tuned. While this model has high reproducibility of stylized facts, it holds similar behavioral properties to those of the sandpile model. The simulation results infer the possible contribution of self-organized criticality for the spontaneous emergence of stylized facts.
