Disease and violence escalates the prevalence of orphanhood. We investigate whether individuals who were orphaned as a child suffer long-term consequences on their pro-sociality. We conduct a lab-in-the-field experiment in rural Uganda where, among other contributing factors, the HIV/AIDS pandemic hit hardest. Subjects made decisions to contribute to a public good. Results indicate that adults who were orphaned as a child contribute less. We provide evidence that an important channel through which the mechanism operates is through social norms. Subjects orphaned tend to have lower expectations regarding typical behaviour of others. A strong interaction effect is identified where those with the lowest expectations who were also orphaned contribute the least to the public good. Thus, we document orphanhood's long-term consequences to a community.

We ask whether access to microfinance loans by the poor has a spillover effect on their pro-social behaviors. An experimental field study in southern, rural Uganda is conducted using free riding in public goods contributions as an assessment. We document higher levels of contributions by those who have previously received a microloan. This effect cannot be explained by changes in social norms, income effects, or sample selection bias. The results suggest that exposure to microfinance promotes social preferences.

Domestic violence generates long-term effects on offenders, victims, and other household members. Insight into triggers of family violence can inform policy and improve services aimed at reducing abusive behavior. We investigate potential domestic violence triggers by analyzing unexpected losses in National Basketball Association games. The literature identifies increasing in-home violence after unexpected losses in the National Football League. Combining information on referee accuracy and fatigue, we develop a unique identification strategy to explore the impact of human error on family violence following unexpected losses. Results indicate that as referees are more accurate (more rested) in unexpected losses, family violence decreases, suggesting that the ability to place blame for a loss on referees increases the likelihood of violent outbursts. Further investigation shows that these results concentrate in games where referees are less rested and betting markets were less certain of the game outcome.
