The "critical window" for obtaining optimal growth and development is from birth to two years old. Under-fives’ growth is significantly impacted by infection, poor child feeding techniques, and inadequate quality and quantity of supplemental foods. In underdeveloped nations, one-third of children under the age of five are stunted, and many of them are also micronutrient deficient. Ensuring appropriate supplementary feeding can reduce an estimated 6% of under-five mortalities. This study is a two-arm cluster randomized controlled trial that aim to improve maternal knowledge, attitudes and practice regarding child feeing practices through strategies such as mid-upper arm circumference (MUAC) measurement, food incentives and behaviour change communication (BCC). In this community-based r...
This randomized trial investigates the impact of app training interventions on technology adoption in shrimp farming communities. The study focuses on addressing perceived complexity barriers by providing digital training to farmers. Findings will contribute insights into effective strategies for promoting technology uptake in agriculture, with implications for enhancing sustainability and productivity in shrimp farming communities.
We study how AI can influence economic interactions by enhancing humans' communication abilities. In particular, we use classic experimental games to investigate the effectiveness of AI-assisted communication within these economic settings: the Dictator Game, the Ultimatum Game, the Trust Game, and the Public Goods Game, aiming to discern the impact of suggestions generated by the state-of-the-art language models, GPT-4 (or 5) and Claude3 (or 4), on enhancing the communication abilities of participants. In our design, we allow players to send AI-aided unilateral pre-play messages to obtain better economic outcomes. Specifically, we assess whether AI assistance can enable players to persuade for larger transfers in the Dictator Game, achieve lower rejection rates or propose more successf...
While commercialization of agriculture has the potential to benefit small-scale producers, the transition to cash cropping does not always improve welfare. Shifts in intra-household allocation arising from this transition may be one explanation. While women often participate in cash crop production, in this context it is almost exclusively men who are responsible for sales and profit allocation. In this study we undertake two interventions to increase women’s participation in cash crop production and management and their access to profits. Can increasing women’s economic empowerment in this way change outcomes at the household level? Random assignment of households into treatment and control groups will allow for a rigorous estimation of the interventions’ impacts. Outcomes of interest ...
How do parents advise their children on decisions about occupational and vocational choices? Is parental occupational advice gender-blind? This study aims to investigate whether i) the child’s gender affects the occupational advice parents give and whether ii) parental, regional, and occupational characteristics potentially drive occupational advice patterns. For this purpose, we run a survey experiment where adults give occupational advice in a hypothetical parent-child scenario.
We study the preferences of adults for their hypothetical child’s educational and career paths. For that purpose, we implement a discrete choice experiment among a representative survey of 6000 adults aged between 25 and 60 in Switzerland where we ask them in multiple choice situations which of two “careers” they would prefer for their child. These careers are defined by the highest educational attainment, wage, the hierarchical position in their job, and the risk that their job will be substituted within the next 10 years. We ask half of the survey sample about their preferences for their hypothetical daughter, and the other half about preferences for their hypothetical son. We investigate how career attributes affect the likelihood of a career being chosen, how these preferences for c...
Armed conflicts cause tremendous human suffering, particularly for displaced populations who lose their homes and sources of livelihood. Armed conflicts have resulted in 48 million people being displaced, either as refugees or Internally Displace People (IDP). Displaced populations are particularly vulnerable to psychological disorders because of war-related traumas before departure and adverse experiences during the transition and after arrival in a new community. Despite their dire need, displaced populations have limited access to mental health services. For this pilot study, around 600 Afghan refugees will be recruited in Istanbul, Turkey, and randomly assigned to (1) a manualized Cognitive Behavioral Therapy (CBT) training that teaches coping and emotion regulation skills, (2) Isla...
Economic transactions may lead to disputes where the weaker party claims economic abuse or injury. A key consideration for whether policy or legislation should intervene is a lack of consent from the weaker party. An important element of consent is the information state of the weaker party at the time of transacting. With decreasing costs of information disclosure, this has led to governments, firms, and legislators inundating consumers with pre-transactional information (or mandating for it to be so). For example, mandatory disclosure "is among the most ubiquitous and least controversial elements of public policy, often promoted as an attractive alternative to so-called hard forms of regulation" (Loewenstein et al, 2014). The appeal of information disclosure stems from the general pres...
Diabetes and diabetes-related complications have reached epidemic levels in urban India. A promising strategy for local governments to reduce the financial and physical burdens of diabetes is to encourage better disease management by patients. Disease management may be particularly poor among impatient and present-biased people, since the costs of management (e.g., exercising more) are borne today but the benefits are realized in the future. Thus, offering financial rewards for healthy behaviors may be a potent tool for improving disease management. However, it is not well understood how to optimally design incentives for impatient and present-biased agents. Two key aspects of the incentive design--the lag between incentivized behavior and payment, and whether the contract is additively...
The challenges and opportunities in livestock farming are different for women smallholder farmers compared to the men influencing individual empowerment and consequently impacting food-security, well-being and livelihood. In several countries, women are primary producers of food and tend to control vital livestock products to produce the same. Studies have demonstrated that women are primary caregivers of cattle, thus empowering women in livestock health decisions can benefit households and communities, as their unique perspectives and skills can contribute to disease prevention and overall livestock management. This study aims to investigate the relationship between women empowerment and cattle health management using a lab in the field experiment. The experiment is scheduled to ta...
