Using the agent-based model, we make the sunspots explicit so that we can test, e.g., by means of the Granger causality test, whether purely extrinsic uncertainty can influence price dynamics. In addition, through agent-based simulation, the coordination process, which is mainly driven by genetic programming, becomes observable, which enables us to analyze what agents perceive and whether they believe in sunspots. By manipulating different control variables, three series of experiments are conducted. Generally speaking, the chances of observing “sunspot equilibria” in this agent-based artificial stock market are small. However, the sunspot believers can never be driven out of the market. Nevertheless, they are always outnumbered by fundamental believers, which is evidence that the market as\r\ncollective behavior is rational. We also find that lengthening the time horizon will make it difficult for sunspot believers to survive. | 關聯: | Journal of Economic Interaction and Coordination, 3(1), 25-41 | 資料類型: | article | DOI: | http://dx.doi.org/10.1007/s11403-008-0037-3 |
