The relation between emotion and rationality is assessed by reviewing empirical findings from multiple disciplines. Two types of emotional phenomena are examined incidental emotional states and integral emotional responses and three conceptions of rationality are considered logical, material,...

This paper suggests a new explanation for the low level of annuitization, which is valid even if one assumes perfect markets. We show that, as soon there exists a positive bequest motive, sufficiently risk averse individuals should not purchase annuities. A model calibration accounting for...

This paper endogenizes the rational short-list method whereby the decision-maker consecutively uses two rationales to finalize her choice. Rather than being exogenously given, it is assumed that choice alternatives themselves induce them. We use a novel inductive decomposition of the weak axiom...

We present a novel approach to finite Rational Inattention (RI) models based on the ignorance equivalent, a fictitious action with state-dependent payoffs that effectively summarizes the optimal learning and conditional choices. The ignorance equivalent allows us to recast the RI problem as a...

Decision-makers are sometimes depicted as impulsive and overly influenced by hot,affective factors. The present research suggests that decision-makers may be too cold and overly focus on rationalistic attributes, such as economic values, quantitative specifications,and functions. In support of...

We derive a family of probabilistic choice models including the multinomial logit model, from a microeconomic model in which the decision maker has to make some effort in order to avoid mistakes when implementing any desired outcome. The disutility of this effort enters the decision maker's goal...

In many real-life decisions, either information about alternatives is missing, or decision makers have limited cognitive capacity to go through all alternatives. To capture these situations, we propose and axiomatically characterize a new descriptive search model in which a decision maker...

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...

Empirical evidence suggests that choices are affected by the amount of time available to the decision maker. Time pressure or a cooling-off period (mandatory delay of choice) changes how choices are determined. Yet, few models are able to account for the role of available time on decisions. This...
