  • Cultural institutions: The Effect of Physical and Digital Layouts on Visitor Experience (Part 2)
    Last registered on June 26, 2022

    A fundamental operational decision faced by museums and other major cultural institutions is the design of a display arrangement for their collection of items (artworks, objects, media contents), which in turn affects the visitors' interactions with the offered experiences. In this project, we collaborate with the Van Gogh Museum in Amsterdam to carry out experiments that help us causally identify potential links between layout-level decisions made by the experience providers and the visitor engagement, satisfaction levels, and learnings. The multimedia guides provided by the museum help us record visitors' movements and activities across time and space through granular event logs. Hence, the visitors navigate through both the physical layout, i.e. the arrangement of exhibits on display...

  • The effect of Universal Unified Prevention Program for Diverse Disorders(UP2-D2) on students' behavior and noncognitive skills
    Last registered on June 26, 2022

    With the widespread of the Covid-19, school-aged children experienced temporary school closures, cancellations and postponements of school events and/or extracurricular activities, and a decrease in oral communication in school. According to the the survey conducted by Saitama Prefecture, 21.1% of schools stopped interactive activities among students and 90.1% of school events and/or extracurricular activities had to be cancelled or postponed. Research showed that 26.0 to 34.5% of school-aged children experienced high levels of anxiety (Ma et al., 2021; Panda et al., 2020). In fact, at the end of the 2020 school year, the number of children who were not attending school in elementary schools in Saitama Prefecture was 2,624, a 23.7% increase from the previous year. The number of cases o...

  • In-Group Competition for Incentives
    Last registered on June 26, 2022

    Governments in developing countries spend billions every year to promote technological adoption. A neglected but important question is how to effectively motivate the extensiion agents hired for such projects. To study the goal structures that are more effective for, we will conduct an experment trial allots hired extenstion agents for a mobile-phone based service to two treatment groups: some agents are given individual goals, while others compete for a share of the goal for the group in their locality. The goals are based on the number of users that agents can register for KasuwaGo an app to help farmers, sellers and resellers to trade with one another. We will compare performance means and dispersion for the two groups by measuring (a) the number of agents that achieve the goals. (b...

  • The development of children’s sophistication about their self-control problems: An intervention in rural Bangladesh
    Last registered on June 26, 2022

    Low self-control in childhood is an important predictor of low income, financial problems, poor physical health, substance dependence, single parenthood and criminal offending in adulthood (Moffitt et al. 2011). However, we do not know yet whether children are aware of their own self-control problems and whether their possible sophistication about (awareness of) their self-control problems mitigates the adverse consequences of low self-control. Behavioral theory predicts that people’s sophistication about their own self-control problems is integral to the choices they make (O’Donoghue and Rabin 1999, 2001). In their seminal theory paper, O’Donoghue and Rabin (1999) draw on the disparity in people’s ideal, predicted and actual choices to identify whether people lack self-control and,...

  • Promoting adoption of digital financial services in refugee and host communities through social networks.
    Last registered on June 26, 2022

    This study examines whether social networks can be used to engage under-represented populations in to enroll in digital financial services among refugee and surrounding host communities in Ethiopia. Partnering with a local service provider, study participantswe will be invited current users of a digital financial service to refer of community members that might be interested in registering for the services. Participants Current users will be randomly assigned to either receive one of three different reward levels for successful enrollmentsrewards (with referral reward amounts , varying by gender of the new enrollees) or to be in a , and a control group that receives no referral rewards. The following subsequent analysis will assess whether this type of referral scheme is an effective ...

  • RANDOMIZED EVALUATION OF THE DEMAND FOR LONG-LASTING MOSQUITO-REPELLENT OINTMENT TO PREVENT FROM MALARIA AND ITS IMPACTS ON CHILDREN’S HEALTH OUTCOMES AND WELLBEING IN BURKINA FASO (DIMORO)
    Last registered on June 26, 2022

    Context and general motivation: In 2018, there were 228 million cases of malaria and 405 000 malaria deaths worldwide (World Malaria Report 2019). The WHO African Region accounts for 93% of malaria cases and 94% of malaria deaths. Children under 5 years of age are the most vulnerable group affected by malaria; in 2018, they accounted for 67% of all malaria deaths worldwide (World Malaria Report 2019). Recently, the focus of prevention is to encourage households to adopt insecticide treated bed nets (ITN) over standard bed nets to increase the positive externalities of each use on the community. However, the benefits of ITN have been recently decreasing as mosquitos become more and more resistant, and bed net protects children and adults if they sleep under it but not during the entire p...

  • Improving Risk Assessment and Treatment Choice in Medical Decision Making
    Last registered on June 26, 2022

    Physicians often face situations in which they must predict patients’ health outcomes under uncertainty. Existing decision tools are based on prediction models derived from clinical data, but typically include only a small set of known risk factors. In clinical practice, physicians often observe additional risk factors and patient characteristics which may improve their risk assessment. By performing an online experiment, we explore a new risk assessment tool that allows physicians to combine their clinical experience and their assessment of a patient’s risk factors with the predictions of a decision tool in a structured way. In doing so, we aim to investigate the behavior of physicians in risk assessment and treatment selection.

  • Climate variability information and adaptation in Kenya
    Last registered on June 26, 2022

    Africa’s climate is warmer than it was 100 years ago and model-based predictions of future climate for the continent clearly suggest that this warming will continue and, in most scenarios, accelerate (Intergovernmental Panel for Climate Change , 2018). Therefore, the study examines how various information on climate variability can encourage farmers to adopt long-term adaptation mechanisms such as irrigation and also be able to differentiate short-term and long term potential adaptation strategies. The study will be based on utility maximization theory where a representative farmer adopts a given climate variability adaptation mechanism that gives a higher net utility. In other words, a given farmer selects a climate change coping strategy given the relevant climate information base...

  • Police Study
    Last registered on June 26, 2022

    Policing policies and police behavior significantly influence political, social and economic landscapes in the United States. Currently, police interactions with the public are under intense scrutiny. I use an RCT to document the possible presence of bias in police departments.

  • Strengthening the Implementation of Responsible Fatherhood Programs (SIRF)
    Last registered on June 26, 2022

    The Strengthening the Implementation of Responsible Fatherhood Programs (SIRF) aims to identify and test approaches to improve recruitment, engagement, and retention of fathers in responsible fatherhood programs using rapid learning cycles. The study includes 10 programs – 9 of which have received Family-focused, Interconnected, Resilient and Essential (Fatherhood FIRE) grants from the Office of Family Assistance in the US Department of Human Services – testing interventions over a one-year period in one of three broad categories: • Coaching. Coaching techniques are employed in case management. Staff members use open-ended questions to talk with fathers about their goals and how to achieve them. This approach is designed to increase the number of fathers who complete the program. • Ou...
