Agent-based modeling of dual currency economy
Vlk, Bořivoj ; Skuhrovec, Jiří (advisor) ; Klinger, Tomáš (referee)
1 Abstract Thesis describes close relationship between Dynamic programming and rein- forcement learning algorithms on the example of a model of a dual currency economy. Dynamic programming is methodology used for deriving equilibria of Search-Theoretic equilibrium monetary models, which provide evidence for emergence of fiat currency or emergence of internationally circulating curren- cies without any human institutions. Particular previously published Search- Theoretic framework of dual currency economy is used as a background for de- velopment of Agent-based Computational model. Both models are compared based on their ability to reach specified equilibria and their assumptions, with the conclusion, that models are closely related and with the same assumptions would have the same results. Agent-based model also provides possibility of relaxing assumptions on perfect information distribution and static environ- ment. In this setting, the model will reach different equilibria, that correspond better to the real human behavior, observed in previously published laboratory experiments.
