An incomplete ignorance state in repeated-play decision making: A note on Bayesian decision-theoretical framework


  • Kobayashi, Yohei
  • Fujikawa, Takemi


There has been much reported on decisions from experience, also referred to as decisions in a complete ignorance fashion. This note lays out a Bayesian decision-theoretical framework that provides a computable account for decisions from experience. To make the framework more tractable, this note sets up and examines decisions in a incomplete ignorance fashion. The current discussion asserts that well-known behavioural effects, such as the hot stove effect, and the Bayesian framework may lead to different predictions.
