Restrictions like work requirements and constraints on voucher transfers are often used in social welfare systems, but little empirical evidence exists on their impact on wellbeing. We conducted a 10-day randomized experiment with 432 individuals living below the poverty line in the Kawangware settlement of Nairobi, kenya, testing two elements of social welfare design: workfare versus welfare and restricted versus unrestricted vouchers. Participants were randomly assigned to a "Work" condition, involving daily work for unrestricted vouchers, or one of two "Wait" conditions, involving daily waiting for vouchers that were either unrestricted or partially restricted to staple foods. We find that working improved psychological wellbeing relative to waiting, suggesting that means of implementing welfare programs may have important effects on individuals beyond the impact of monetary benefit alone. Furthermore, although restrictions were inframarginal, partially restricted vouchers crowded-in spending on staple foods, suggesting the existence of a "flypaper effect" in spending from restricted vouchers.

Intestinal helminths - including hookworm, roundworm, schistosomiasis, and whipworm - infect more than one-quarter of the world's population. A randomized evaluation of a project in Kenya suggests that school-based mass treatment with deworming drugs reduced school absenteeism in treatment schools by one quarter; gains are especially large among the youngest children. Deworming is found to be cheaper than alternative ways of boosting school participation. By reducing disease transmission, deworming creates substantial externality health and school participation benefits among untreated children in the treatment schools and among children in neighboring schools. These externalities are large enough to justify fully subsidizing treatment. We do not find evidence that deworming improves academic test scores. Existing experimental studies, in which treatment is randomized among individuals in the same school, find small and insignificant deworming treatment effects on education; however, these studies underestimate true treatment effects if deworming creates positive externalities for the control group and reduces treatment group attrition.

This study examines social preferences in three distinct field environments. In the first field setting, I allow consumers of all age and education levels to participate in one-shot and multiple-shot public goods games in a well-functioning marketplace. The second field study, an actual university capital campaign, gathers data from mail solicitations sent to 2,000 Central Florida residents. In the third field experiment, I examine data from an uncontrolled environment, a television gameshow, which closely resembles the classic prisoner's dilemma game. Several insights emerge; perhaps the most provocative is that age and social preferences appear linked.
