"Waste not want not" expresses our culture's aversion to waste. "I could have gotten the same thing for less" is a sentiment that can diminish pleasure in a transaction. We study people's willingness to "pay" to avoid this spoiler. In one scenario, participants imagined they were looking for a...

We examine experimentally the effect of complexity on individual decision making. We focus on credit choices, as they have been widely criticized for their complexity in recent years. In a first study, we find that complexity in benefits leads to random mistakes, while complexity in costs leads...

Which behavior-based interventions are more appropriate to induce energy saving: energy saving goals with or without incentive, energy saving products, environmentally related information, social comparison or competition? We try to answer this question in a comprehensive study. First, we...

We propose a model of instrumental belief choice under loss aversion. When new information arrives, an agent is prompted to abandon her prior. However, potential posteriors may induce her to take actions that generate a lower utility in some states than actions induced by her prior. These losses...

We present a model of boundedly rational play in single-shot 2 × 2 games. Players choose strategies based on the perceived salience of their own payoffs and, if own-payoff salience is uninformative, on the perceived salience of their opponent's payoffs. When own payoffs are salient, the model's...

This paper studies the role of goal bracketing to attenuate time inconsistency. When setting non-binding goals for a multi-stage project, an agent must also decide how and when to evaluate himself against such goals. In particular, he can bracket broadly by setting an aggregate goal for the...

The decision maker is assumed to observe a large number of experiments. The paper presents conditions for the existence of a unique prior over distributions that generate each of the observed samples. The axioms over experiments admit a recursive non-expected utility representation over...

The model of time-inconsistent procrastination by O'Donoughe and Rabin shows that individuals who are not aware of their present-bias (nai͏̈ve) procrastinate more than individuals who are aware of it (sophisticated) or are not present-biased (time-consistent). This paper tests this prediction....

On whom do food safety announcements have the least impact? Building on research on cognitive dissonance and confirmatory bias, this study shows that consumers tend to inadequately process (food safety) information, pay limited attention to signals, and make purchase decisions that are biased...
