  • Electoral reciprocity in programmatic redistribution: Evidence from Honduran experiments
    Last registered on August 23, 2016

    This paper analyzes the impact of Honduran conditional cash transfers on turnout and incumbent vote share in presidential elections, using two randomized experiments. Before the 2001 presidential elections, the PRAF-II experiment randomly assigned households in 40 of 70 municipalities to receive small conditional cash transfers, only intended to cover the costs of complying with education and health conditions (Galiani and McEwan, 2013; IFPRI, 2000). Then, in late 2011, the Bono 10,000 experiment randomly assigned 816 villages to three treatment arms. Of these, 150 of these were randomly selected for the treatment group, and another 150 were randomly selected for the control group. The former received the treatment immediately after the baseline was completed, and the latter received it...

  • The Role of Information in Agricultural Technology Adoption: Experimental Evidence from Rice Farmers in Uganda
    Last registered on August 23, 2016

    Previous research identified information inefficiencies as a major constraint to sustainable crop intensification among rice farmers in Eastern Uganda. The fact that some farmers report not using certain inputs or techniques because they are not aware of them while others report they are aware of them but are not using them suggests information gaps at two levels. First, farmers may lack knowledge about the existence or use a particular input or technology. Second, a farmer may not be aware of the returns to using the technology. In this study we therefore try out two different information treatments at the individual level. In a first intervention, we show farmers the recommend practices and inputs in rice farming. In a second intervention, we point out the returns to investment in a s...

  • Effectiveness of provider incentives for anaemia reduction in rural China: a cluster randomised trial
    Last registered on August 23, 2016

    OBJECTIVE: To test the impact of provider performance pay for anaemia reduction in rural China. DESIGN: A cluster randomised trial of information, subsidies, and incentives for school principals to reduce anaemia among their students. Enumerators and study participants were not informed of study arm assignment. SETTING: 72 randomly selected rural primary schools across northwest China. PARTICIPANTS: 3553 fourth and fifth grade students aged 9-11 years. All fourth and fifth grade students in sample schools participated in the study. INTERVENTIONS: Sample schools were randomly assigned to a control group, with no intervention, or one of three treatment arms: (a) an information arm, in which principals received information about anaemia; (b) a subsidy arm, in which principal...

  • Every child counts! Towards a scalable curriculum for early mathematics.
    Last registered on August 22, 2016

    The performance of primary schools in developing countries is weak, especially for the poor. This can be partly attributed to initial differences, which are later magnified by the school system (Banerjee & Duflo, 2011). The massive expansion in school attendance in developing countries has not been matched by increases in school achievement for the poor. In India, 75% of children in grade five cannot perform simple arithmetic and 53% cannot read a grade-two level paragraph (ASER: Pratham, 2013). Because poor children have especially weak preparation for school but strong non-symbolic numerical and geometrical abilities (Spelke, 2011), preschool is a promising time to intervene, with little established curricula. Yet, there is little evidence on effective school-readiness curricula for ...

  • Effect of Astym therapy versus kinesiotaping on rotator cuff tendinopathy in diabetic patients :RCT
    Last registered on August 22, 2016

    Background rotator cuff tendinopathy is a significant problem among diabetics, that frequently restricts patients activity in term of pain and disability. The purpose to compare the efficacy of Astym therapy and kinesio tape in diabetic patients with chronic rotator cuff tendinopathy. Study Design: single blind randomized controlled trial .Subjects and methods 56 diabetic patients diagnosed with chronic rotator cuff tendinopathy were randomly assigned into Astym therapy group (n=28) or kinesiotaping group (n= 28) . All patients received conventional program in the form of hot backs and exercise in addition to Astym treatment or Kinesiotaping for 12 sessions (2times/week). Patients were assessed at baseline and at the end of corresponding intervention with visual analog scale (VAS) for ...

  • Can Active Labor Market Policies Combat Youth Unemployment in Denmark?
    Last registered on August 21, 2016

    Active labour market policies (ALMPs) may play an important role in preventing an increase in long-term unemployment following the Great Recession. We consider this issue for Denmark, a country relying extensively on this instrument. We present evidence on the effectiveness of ALMPs as a way of fighting youth unemployment using results from a randomised controlled trial (RCT) that intensified the use of ALMPs. The intervention was conducted after the onset of the financial crisis, and the findings are relatively unfavourable in the sense that further intensification of an already quite intensive effort for youth did not increase employment. In addition, the intensification of ALMPs seems to have in-creased transitions into sickness benefits.

  • Randomized Impact Evaluation of the Community Auxiliary Police, Bougainville, Papua New Guinea
    Last registered on August 20, 2016

    In developing countries, the state is often unable to deliver the protections of the law to all its citizens. When the state’s reach is limited, the few interactions citizens have with police are often marked by corruption, absenteeism, or abuse, contributing to dissatisfaction and distrust. These citizens sometimes instead rely on informal security providers, such as chiefs, families, or mobs, whose punitive and remedial procedures may be biased toward certain social groups at the expense of other groups. For example, men may receive systematically more beneficial outcomes from the informal justice system than women. This study seeks to measure the effectiveness of a novel project implemented in Papua New Guinea by the New Zealand and Bougainville Police Services that seeks to overc...

  • Accuracy and Updating: How Labels and Initial Performance Affect Teacher Grading
    Last registered on August 20, 2016

    Accurate grades help students, parents, teachers, and administrators allocate resources to improve student learning. Moreover, many life-altering institutional decisions are based on grades, such as whether or not students are given opportunities to pursue high performance tracks. Unfortunately, recent studies have shown that inaccuracies in grading occur when teachers rely on student labels (such as ethnicity or caste) to inform their grading. Moreover, studies have shown large inaccuracies in grading occur when teachers rely on labels about a student’s prior grades to assign grades. With the above in mind, we have four goals in mind for this study. First, we seek to validate prior studies by examining how teacher assessments are affected by information about a student's prior perfo...

  • General Equilibrium Effects of Cash Transfers in Kenya
    Last registered on August 20, 2016

    How redistribution affects the real economy is one of the central, unanswered questions in development economics. The effect of redistribution on the welfare of non-beneficiary households is theoretically ambiguous: there could be positive spillover effects through increased aggregate demand (a multiplier effect), or negative spillovers from price inflation or crowd-out by business expansion for non-beneficiaries. The NGO GiveDirectly provides large cash transfers to rural households in Kenya. We utilize an RCT to study the spillover effects of cash transfers on household welfare, prices, enterprise creation and local public finance and will make use of spatial variation in treatment density in order to estimate these effects.

  • Evaluation of the Welfare Impacts of a Livestock Transfer Program in Nepal
    Last registered on August 19, 2016

    Between September 2014 and September 2015, HI administered productive asset transfers to poor households living in three distinct agro-ecological zones of Nepal. The present RCT assigned three treatments at the village level: Treatment one delivered a full package of benefits to program participants, including physical capital (goats), human capital formation, and social capital formation. Treatment two withheld the physical capital from beneficiaries; treatment three withheld social capital formation. Within treatment groups we further sub- divided the sample so as to capture indirect effects, both programmed and unprogrammed. The present document outlines the outcome variables and econometric methods we will use to assess the effect of the program on assets, income, non-food consumpti...
