Observed individual behavior in the presence of ambiguity is characterized by insufficient responsiveness to changes in subjective likelihoods. Such likelihood insensitivity under ambiguity is integral to theoretical models and predictive of behavior in many important domains such as financial...

Observational learning theories often assume that people's actions can be observed. However, in many naturally-occurring environments, individuals can choose whether to disclose their behavior to others. We provide theoretical analysis of observational learning under optional disclosure...

Decision-makers commonly avoid information on uncertain social effects of their privately beneficial choices. The dominant theory holds that such "strategic ignorance" is a means to circumvent inner moral conflict while acting self-servingly. In extension of the theory, we hypothesize that time...

Ignorance enables individuals to act immorally. This is well known in policy circles, where there is keen interest in lowering moral ignorance. In this paper, we study the (in)elasticity of moral ignorance, with respect to monetary incentives, social norms messages and moral context. We propose...

We test the hypothesis that strategic interactions foster overconfidence. We experimentally compare an environment where players have an incentive to overstate their own ability to deter competitors, with one where this incentive is removed. We find that overconfidence persists in the former...

This paper experimentally investigates structured investment decision-making with sequential information provision. Subjects were asked to rank investment alternatives using a scoring model. A mixed design with information provision as the within-subject variable and initial information load as...

How do individuals process non-diagnostic information? According to Bayes’ Theorem, signals which do not carry relevant information about the objective state of the world are treated as if no signal occurred. This paper provides experimental evidence that individuals update their expectations...

Many economic decisions, such as whether to invest in developing new skills, change professions, or purchase a new technology, benefit from accurate estimation of skill acquisition. We examine the accuracy of such predictions by having experimental participants predict the speed at which they...

Payments and discounts incentivize participation in many transactions about which people know little, but can learn more --- payments for medical trial participation, signing bonuses for job applicants, or price rebates on consumer durables. Who opts into the transaction when given such...

Ignorance enables individuals to act immorally. This is well known in policy circles, where there is keen interest in lowering moral ignorance. In this paper, we demonstrate the relevance of demand elasticity to ignorance by showing that small monetary incentives can significantly reduce...
