We present a novel descriptive model of choice that achieves an efficient representation anchored to how the brain represents value. An individual's behavior is fully described by two primitives: an individual's "reward expectation'' and a free parameter we call "predisposition''. We demonstrate...

Abstract Recent advances in neuroscience suggest a utility-like calculation is involved in how the brain makes choices, and that this calculation may use a computation known as divisive normalization. While this tells us how the brain makes choices, it is not immediately evident why the brain...

Prior information is invaluable to decision makers facing noisy evidence, allowing them to increase their chances of choosing the best option. Yet human choice behavior often exhibits base-rate neglect. In order to better understand the mechanisms underlying such sub-optimal behaviors, we...

Prospect theory, widely used descriptively for decisions under both risk and certainty, presumes concave utility over “gains” and convex utility over “losses”; a pattern widely seen in lottery tasks. Although such gain-loss asymmetry is also widely used to model riskless choices, limited...

Weather, in particular the intensity and duration of sunshine (luminance), has been shown to significantly affect market outcomes. Yet, because of the complexity of market interactions we do not know how human behavior is affected by luminance in a way that could inform microeconomic choice...

We study the falsifiability and identification of Quantal Response Equilibrium (QRE) when each player's utility and error distribution are relaxed to be unknown non-parametric functions. Using variations of players' choices across a series of games, we first show that both the utility function...
