Abstract:
This presentation overviewed studies on human decision-making from the view point of “rationality”.
In the field of economics, a perfectly-rational model has been posited classically as a decision-maker with the following embedded assumptions: (1) full knowledge of the problem – the agent is fully aware of the set of action alternatives; (2) clear preferences – the agent has a complete ordering over the entire set of alternatives; and (3) ability to optimize – the agent has unlimited ability to make whatever complicated calculations are necessary to discover optimal actions, and it never mistakes. Nevertheless, classical theories based on this model differ markedly from observed practices of actual humans. Therefore, bounded rationality has become a central theme as an alternative to perfect rationality in recent economic studies. These studies relax the assumptions applied to the agent models: agents are given limited knowledge of alternatives and their ordering, and limited ability to optimize. The representative theories or models that presuppose agents’ bounded rationality are: Satisfactory Standard, Prospect Theory, Heuristic models. Bounded rationality will also become essential as a characteristic of artificial agents in order to design flexible or adaptive artifactual multi-agent systems like systems including humans.
