An agent wants to derive her belief over outcomes based on past observations collected in her database (memory). There is well establish evidence in the psychology and marketing literature that agents consistently fail (or choose not) to process all available information. An agent might be...

Beliefs are intuitive if they rely on associative memory, which can be described as a network of associations between events. A belief-theoretic characterization of the model is provided, its uniqueness properties are established, and the intersection with the Bayesian model is characterized....

For choice with deterministic consequences, the standard rationality hypothesis is ordinality, i.e., maximization of a weak preference ordering. For choice under risk (resp. uncertainty), preferences are assumed to be represented by the objectively (resp. subjectively) expected value of a von...

This paper presents a new decision theory for modelling choice under risk. The new theory is a two-parameter generalization of expected utility theory. The proposed theory assumes that a decision maker: 1) behaves as if maximizing expected utility; but 2) may experience disappointment (elation)...

In his paper Emotion and reasoning in human decision-making (Economics Discussion Papers, No 2019-8) Edmund Rolls points out that multiple and independent types of reinforcement exist in the human brain, and that they cannot be reduced to a common currency. The present commentary introduces...

Two systems in the brain that are involved in emotional and economic decision-making are described. The first is an evolutionarily old emotion-based system that operates on rewards defined by the genes such as food, warmth, social reputation, and having children. Such decisions are often based...

Past research has shown that people often take punitive actions towards norm violators even when they are not directly involved in transactions. However, it at the same time suggests that such third-party punishment may not be strong enough to enforce cooperation norms in dilemma situations....

Whether, and if so, how exactly gender differences are manifested in moral judgment has recently been at the center of much research on moral decision making. Previous research suggests that women are more deontological than men in personal, but not impersonal, moral dilemmas. However, typical...
