This study examines how social context influences women’s demand for menstrual health technologies in Uganda. While improved menstrual products are increasingly available, adoption remains low even when cost barriers are reduced. We investigate whether social visibility and household dynamics affect willingness to pay for these technologies. We implement a framed field experiment that varies both information provision and the social context in which choices are made. Participants make incentivized purchase decisions for a set of menstrual products under different conditions. This design allows us to estimate baseline demand, as well as the impact of information and social environment on adoption decisions. Primary outcomes capture willingness to pay for different products. The stu...
This study uses an online experiment to examine how consumers respond to different types of cash rebates linked to environmentally relevant consumption choices. Participants make repeated decisions about how many units of a product to purchase under a fixed price that reflects a carbon charge, with lower consumption associated with greater environmental benefits. We compare behavior under several treatments inlcuding a no rebate control, a guaranteed cash rebate, and several probabilistic rebate schemes that differ in the likelihood of rebate payment. The study is designed to assess whether probabilistic rebates generate similar behavioral responses to guaranteed rebates, and to examine whether responses vary systematically with the probability of receiving a rebate. This experiment con...
We plan to implement an online survey among respondents in Kenya. The survey builds on the findings from a previous data collection in which we find strong positive relationship between religious leaders’ and congregants’ preferences (pro-sociality and behavior towards people with different religious affiliations) and substantial heterogeneity across individual church communities – some are tolerant and some do discriminate. The new survey will focus on estimating the influence of leaders. We will elicit attitudes and controlled measures of social behavior to people from different religious groups and randomize whether the respondents answer the survey before or after a sermon, in which their religious leader will focus on the topic of social behavior and inter-group tolerance.
We explore the role of emotions such as guilt-aversion and shame-aversion, and of social/workplace norms in the determining effort choices of team members. We build a rigorous beliefs-based model to derive predictions in four different treatments that isolate the effects of various emotions and social norms. Participants will be asked to choose the amount of effort they wish to exert in a team project, while being aware of either their team partner’s effort expectations (private signals), their social group’s effort expectations (social signals with and without sanctions), or a combination of both expectations.
This study investigates how experiencing unequal opportunities firsthand influences redistributive preferences and beliefs about fairness. Participants are randomly assigned to perform either an easy or a hard version of an effort task that appears identical across conditions but subtly differs in difficulty, mimicking hidden structural barriers. After this experience, all participants act as impartial spectators and decide how to redistribute income between two agents who faced unequal opportunities in the same task. By comparing redistribution choices and belief updating across those who experienced advantage (easy task) and disadvantage (hard task), we test whether direct exposure to inequality increases fairness-driven redistribution, shifts attributions from effort to circumstance,...
While much attention has been dedicated to the health and well-being of children under 5, the needs of older children have been historically overlooked. However, children between 5- and 14-years face health-related challenges higher than previously realized, during a period of life critical for physical, psychological, cognitive and social development. In Zambia, the context for this study, the prevalence of malaria is highest in children aged 5-17, with 40% of children testing positive in endemic areas; a study based in Lusaka, the capital also reported high levels of morbidity in primary school children, with 35% reporting febrile symptoms in the past two weeks, 66% reporting cough, 25% reporting diarrhea, and 32% having worms in their stool. Many of these problems are caused or compo...
Previous research has shown randomising the language of public goods games leads to significantly different contribution levels for bilingual subjects. However, the mechanism is not well understood. In the first paper described here we will measure norms and expectations, testing each as candidate mechanisms. Do bilingual people contribute more in one language because they feel they should, expect others to do so, or have internalised certain behaviours? This has direct relevance for bilingual subjects (the majority of the world) as well as shedding light on the importance of frames for revealed preferences. In addition to testing mechanisms, this experiment will act as a robustness check on Clist & Verschoor (2017, JDE), by examining the same question in a new (urban) setting. In a...
In collaboration with a large charitable organization, we conduct a large-scale field experiment designed to investigate the role of group identity for individual donation decisions in a natural setting. In particular, we test the hypothesis that perceived group membership in combination with group competition have the potential to increase charitable giving. The intervention takes place in July 2021. In addition to the main research question, the project aims at shedding light on (I) whether it needs explicit incentives for salient group membership to have a positive effect on individual donation decisions, (II) whether public recognition as a group-level incentive can increase charitable giving, and (III) whether potential effects of group identity on charitable giving can be further...
In collaboration with a large charitable organization, we conduct a large-scale field experiment designed to investigate the role of group identity for donation decisions in a natural setting. In particular, we test the hypothesis that perceived group membership has the potential to increase charitable giving. The interventions takes place in June and July 2021. In addition to the main research question, the project aims at shedding light on (I) whether it needs explicit incentives for salient group membership to have a positive effect on individual donation decisions, (II) where to locate the appeal to be most effective, and (III) whether effects of group identity on charitable giving can be further exploited by a supplementary peer-to-peer fundraising method. After approximately twelv...
We study fiscal accountability in a laboratory election environment in which candidates compete over a full fiscal platform consisting of a budget and its allocation between a public good and private rents. The theory predicts that more disproportional power-sharing rules raise the electoral stakes of winning and therefore discipline rent extraction. The experiment is designed to test five hypotheses. First, greater power-sharing disproportionality should reduce corruption, increase public-good provision, and improve aggregate voter welfare. Second, if voters behave fully rationally, human voters should not differ from automated utility-maximizing voters. Third, explicit disclosure of rents should not matter when voters can infer rents from the budget constraint. Fourth, greater disprop...
