  • 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 (www.juanfe.org), 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...

  • Do Flexible Repayment Schedules Improve the Impact of Microcredit? Evidence from a Randomized Evaluation in Rural India
    Last registered on April 19, 2017

    Microcredit institutions typically apply rigid and fixed repayment schedules when disbursing loans in order to reduce transaction costs, simplify procedures, and inculcate fiscal discipline for better repayment behavior. Microcredit clients, however, often have neither the smooth income nor singular moments in which to make lumpy investments throughout the year. This mismatch generates a cash flow disconnect and, given the presumed liquidity constraints of the typical microcredit client, a potential welfare loss. Using data from a randomized evaluation with dairy farmers in rural India, we test the impact of flexible microcredit repayment schedules relative to "normal" inflexible, fixed repayment schedules. Although we are only able to track those who borrow, which introduces potent...

  • Does Corruption Information Inspire the Fight or Quash the Hope? A Field Experiment in Mexico on Voter Turnout, Choice, and Party Identification
    Last registered on April 19, 2017

    Retrospective voting models assume that offering more information to voters about their incumbents' performance strengthens electoral accountability. However, it is unclear whether incumbent corruption information translates into higher political participation and increased support for challengers. We provide experimental evidence that such information not only decreases incumbent party support in local elections in Mexico, but also decreases voter turnout and support for the challenger party, as well as erodes partisan attachments. While information clearly is necessary to improve accountability, corruption information is not sufficient because voters may respond to it by withdrawing from the political process. We conclude with a discussion of the implications of our findings for s...

  • The Impacts of Drought Tolerance on Local Labor Markets in India
    Last registered on April 19, 2017

    Drought is a significant problem that affects rainfed agriculture in many parts of South Asia and Africa. While it is well known that drought has negative impacts on producers, the impacts of drought on farm workers are not as well understood. Given that farm workers rely critically on an abundant harvest for work opportunities, and that their geographical mobility is notably low, technologies that stabilize harvests can in theory impact farm workers positively - one of the most marginalized populations. We ask whether new drought-tolerant rice varieties have impacts on local labor markets. Specifically, can these technologies provide insurance to landowners and at the same time provide insurance to the landless laborers? In a well-known article, Jayachandran (2006) showed that weath...
