This paper provides strong evidence supporting the long-standing speculation that decision-making in groups has a dark side, by magnifying the prevalence of anti-social behavior towards outsiders. A large-scale experiment implemented in Slovakia and Uganda (N=2,309) reveals that deciding in a...

Can a short survey instrument reliably measure a range of fundamental economic preferences across diverse settings? We focus on survey questions that systematically predict behavior in incentivized experimental tasks among German university students (Becker et al. 2016) and were implemented...

Heterogeneity in time discounting may reinforce the existing barriers to save and invest faced by rural populations in developing countries. We elicit a subjective discount rate for a varied sample of Ugandan villagers. In accordance with other studies, we have found the discount rate to...

Microcredit is an innovative financial tool designed to reduce poverty and fix credit market imperfections. We use experimental measures of time discounting and risk aversion for villagers in south India to highlight behavioral features of microcredit. Conditional on borrowing from any source,...

Aggressive behavior against out-group members often rises during periods of economic hardship and health pandemics. Here we test the widespread concern that the Covid-19 crisis may fuel hostility against people from other nations or ethnic minorities. Using a controlled money-burning task, we...

Identifying sources of vaccine hesitancy is one of the central challenges in fighting the Covid- 19 pandemic. In this study, we focus on the role of public misperceptions of doctors' views. Motivated by widespread concern that media reports create uncertainty in how people perceive expert...

We test whether an environment of poverty affects time preferences through purely psychological channels. We measured discount rates among farmers in Uganda who made decisions about when to enjoy entertainment instead of working. To circumvent the role of economic constraints, we experimentally...

This paper provides experimental evidence showing that members of a majority group systematically shift punishment on innocent members of an ethnic minority. We develop a new incentivized task, the Punishing the Scapegoat Game, to measure how injustice affecting a member of one's own group...
