  • Research as Leisure: Experimental Evidence on Voluntary Contributions to Science
    Last registered on April 24, 2017

    Understanding why people have a desire to participate in science has critical implications for policy in public and private organizations, and for economic development and productivity more generally. Despite the importance of how and why people contribute to science, we know very little about these questions beyond the importance of career concerns for professional scientists. With the rise of crowd-sourcing and voluntary digital content provision, the potential for voluntary scientific contributions to advance scientific discovery could be large. Importantly, career concerns are unlikely to be important motivators for these volunteers. In this paper, we investigate why people voluntarily contribute to science and whether this desire can be increased through certain non-monetary incent...

  • Impact Evaluation of Bridges to Success
    Last registered on April 24, 2017

    More than 46 million people in the United States live in poverty. The issue of poverty is particularly pervasive in the city of Rochester, NY. The Rochester-Monroe Anti-Poverty Initiative (RMAPI), in partnership with the New York Governor's State Anti-Poverty Task Force, is piloting a program to target poverty in the Rochester-Monroe region. Exhaustive community research has led RMAPI to pilot an adult mentor/navigator program that addresses the issues identified as pervasive in the city of Rochester: a knowledge gap about available services and how to navigate them, and a need for coordinated services. In order to measure the pilot's success and make decisions about scaling the program up, RMAPI has asked the Wilson Sheehan Lab for Economic Opportunities from the University of Not...

  • Using Behavioral Economics to increase charitable giving through phone calls.
    Last registered on April 24, 2017

    We study the effectiveness of different verbal nudges in charitable donations. We partnered with the largest charity in Chile, who routinely communicate with their donors through their own call center. We designed several scripts using nudges that build on behavioral economics' findings. We test how each script affects (a) donations and (b) their willingness to change their current donation to an inflation indexed currency.

  • Evaluating smallholder livelihoods and sustainability in Indonesian coffee value chains
    Last registered on April 22, 2017

    According to the Indonesian Coffee and Cocoa Research Institute (ICCRI), Indonesia had about 1.2 million hectares in coffee production in 2012, 96% of which is managed by smallholder farmers (ICCRI, 2012). ICCRI estimates that the number of smallholder farmers working in the Indonesian coffee sector reached 1.97 million in 2012, with an average of 0.6 ha of land ownership per farmer. According to the 2014 State of Sustainability Initiatives Report, about 11% of Indonesia’s coffee production is certified organic or to a recognized sustainability standard (notably Starbucks C.A.F.E Practices, UTZ Certified, Fairtrade, Rainforest Alliance, or 4C). This study is carried out in the Semendo region in South Sumatra. According to local government data (BPS, 2015), 15,440 ha of land in Semend...

  • Model of Reading Engagement
    Last registered on April 21, 2017

    Despite investing millions of dollars in large-scale literacy interventions and programs, researchers, policymakers, and educators are struggling to improve low-income children’s reading comprehension outcomes. In urban districts like Charlotte-Mecklenburg, North Carolina (CMS), only 27% of low-income children read proficiently on the Grade 4 National Assessment of Reading, which assesses students’ reading comprehension—that is, their ability to form a deep understanding of science and social studies texts. To address the challenge of accelerating low-income children’s reading comprehension, district leaders in Charlotte, NC have undertaken a strategic plan to improve students’ ability to read and write with evidence in response to informational text. Despite the progress made to date, ...

  • Impact Evaluation of a Teenage Mother Program in Colombia
    Last registered on April 21, 2017

    The objective of the evaluation is to assess the impact of the "Teenage Mother Program" designed and implemented by Fundación Juanfe (, a non-profit and non-gubermental organization working to improve the quality of life of pregnant teenagers and their offspring. The Program is expected to have a positive impact on the mothers' socio-emotional development (primarily on self-esteem, self-efficacy and aspirations), educational attainment (through vocational training), their employability, their access to sexual and reproductive health services, the quality of their relationship with their children, and their access to nutritional and medical assistance for their children. After almost 8 years of in the field experience, the Organization has identified several sources of vu...

  • Reducing Anemia through Food Fortification at Scale
    Last registered on April 21, 2017

    Anemia is the most common form of malnutrition, affecting approximately 1.6 billion people world-wide. Most commonly caused by iron deficiency, its adverse effects include increased mortality (especially during childbirth), impaired cognitive development among children, chronic fatigue, and reduced lifetime earnings. While iron deficiency is the main cause of anemia worldwide, its etiology is complex and it can also be caused by an insufficient intake of other micronutrients such as Vitamin A, B9, B12 and folate as well as by helminthic infections and malaria. Research in India and elsewhere has shown that under ideal (controlled) conditions, anemia can be reduced by consumption of iron-fortified food and other micro-nutrients. However, much less is known about the effectiveness of...

  • Self-Promoted Altruism: Looking Bad by Doing Good?
    Last registered on April 20, 2017

    In the experiment participants will be able to collect money to The Red Cross in a real effort task resembling the task used by Ariely, Bracha, and Meier (2009). We introduce two different treatments in which we vary the mechanism with which information about donations and the person donating is made public. In both treatments only the 10 participants with a highest donations are announced to everyone by name. Whereas this disclosure of participants' names is automatic in the first treatment, this is subject to choice in the second. We hypothesize firstly, that a significant share of participants in the second treatment will choose to not disclose their name, thereby forego the opportunity to gather social esteem. Secondly, that this behavior by some subjects devalues the opportunity to...

  • The water savings and methane reductions from improved irrigation management in Bangladesh
    Last registered on April 20, 2017

    Historically, rice is grown in fields that are flooded during most of the monsoon season. However in recent years, mainly due to the availability of tube well irrigation, rice is increasingly being planted in the dry season using shallow or deep tube well water. This trend has led to an increase in groundwater extraction and depletion of water levels in many rice-producing regions. Researchers at the International Rice Research Institute have developed a technology called Alternate Wetting and Drying (AWD) that works on the principle that the rice plant can tolerate up to 30% less water supply during the growing season relative to conventional methods of irrigation. This technique requires embedding a perforated plastic tube to monitor the water level in the rice field, which is irr...

  • Does Knowledge of Constitutional Principles Increase Support for Civil Liberties in the United States?
    Last registered on April 20, 2017

    For decades, scholars have argued that education causes greater support for civil liberties by increasing students' exposure to political knowledge and constitutional norms, such as due process and freedom of expression. Support for this claim comes exclusively from observational evidence, principally from cross-sectional surveys. This paper presents the first large-scale experimental test of this proposition. More than 1000 students in 59 high school classrooms were randomly assigned to an enhanced civics curriculum designed to promote awareness and understanding of constitutional rights and civil liberties. The results show that students in the enhanced curriculum classes displayed significantly more knowledge in this domain than students in conventional civics classes. However, we fi...
