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...

We study two psychological channels how poverty may increase impatient behavior -- an effect on time preference and reduced attention. We measured discount rates among Ugandan farmers who made decisions about when to enjoy entertainment instead of working. We find that experimentally induced...

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 show how sanctioning is more effective in increasing cooperation between groups than within groups. We study this using a trust game among ethnically diverse subjects in Afghanistan. In the experiment, we manipulate i) sanctioning and ii) ethnic identity. We find that sanctioning increases...

We use a set of experiments to study the effects of forced military service for a rebel group on social capital. We examine the case of Northern Uganda, where recruits did not self-select nor were systematically screened by rebels. We find that individual cooperativeness robustly increases with...

The stability of many post-conflict societies rests on the successful reintegration of former soldiers. We examine social capital of former soldiers in Northern Uganda, where the Lord's Resistance Army forcibly recruited tens of thousands of youth during a recent brutal conflict. We use a set of...

This paper studies gender heterogeneity in preferences. We used experimental methods to elicit the subjective discount rate and attitude toward risk in Indian villages. Results show that women made more patient choices than men and that their discount rate is related to number of children. No...
