Optimize, satisfice, or choose without deliberation? A simple minimax-regret assessment

摘要

Simon (Q J Econ 69:99-118, 1955) introduced satisficing, but he did not provide a precise definition or analysis. Other researchers have subsequently interpreted satisficing in various ways, but a consensus perspective still has not emerged. This paper interprets satisficing as a class of decision strategies that a person might use when seeking to optimize in a setting where deliberation is costly. Costly deliberation lies at the heart of Simon's motivation of satisficing, but he did not formalize the idea. I do so here, studying decision making as a problem of minimax-regret planning in which costly deliberation enables a person to reduce ambiguity. I report simple specific findings on how the magnitude of deliberation costs may affect choice of a decision strategy.
