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...

Public discord between those vaccinated and those unvaccinated for COVID-19 has intensified globally. Theories of intergroup relations propose that identifying with one's social group plays a key role in the perceptions and behaviors that fuel intergroup conflict. We test whether identification...

This paper introduces a key factor influencing households' decision to invest in the stock market: how people view stockholders. Using survey data from the US and the Netherlands, we first document that the overwhelming majority of respondents view stockholders negatively - they are perceived as...
