  • Evaluating the Effect of the Primary Literacy Project on Literacy and Academic Achievement
    Last registered on November 17, 2017

    Despite ongoing efforts from both the Government of Uganda and the international donor community, many children in Uganda still are not acquiring literacy skills at a satisfactory level. This project evaluates an innovative new educational paradigm, the Primary Literacy Project (PLP), which currently focuses on P1 to P3 (first- to third-grade) students, employing a mother-tongue-first instructional approach and extensive teacher support and training. Using a randomized controlled trial this study measures the effects of the PLP on learning outcomes. We study 128 schools, which were randomly assigned to either the full PLP, a half-program that includes the materials from the PLP but where the training is provided through government-employed coordinating centre tutors (CCTs), or a control...

  • A Natural Field Experiment on (Community) Incentives in Bicycle-share Systems
    Last registered on November 17, 2017

    We have partnered with a major US city that has recently developed its bicycle-sharing system to increase access to healthy and environmentally sustainable transport for its citizens. Historically, the city's transit agencies have used sign-up discounts to incentivize residents to utilize publicly provided transportation options. However, insights from behavioral science and economics have demonstrated that financial incentives may not be the most (cost-) effective means of encouraging individuals to make presumably welfare-maximizing decisions on the margin. Here, we aim to understand the importance of personal and community incentives in motivating individuals to participate in the city’s newly expanded bicycle sharing system, a service that may arguably be underutilized due to bot...

  • How scarcity affects borrowing decisions in groups
    Last registered on November 17, 2017

    When the means to an end are scarce, decisions makers focus their attention, using available resources most effectively. However, this increased focus comes at a cost. Decision makers lose oversight and neglect important but less pressing long-term projects. They borrow too much and overall performance decreases as a consequence. Until now, this research has concentrated on individual decision makers. We study how scarcity affects borrowing decisions in groups. Do groups also neglect long-term projects under scarcity? Do groups borrow to meet the needs of the present, and thereby compromise the ability to meet their needs in the future, to the same extent as individuals do? Our experimental design builds directly on the 4th experiment of Shah et al (Science, 338 (6107): 682-685, 2012). ...

  • Building informed trust: Developing an educational tool for injection practices and health insurance in Cambodia
    Last registered on November 17, 2017

    Unnecessary injections increase the risk of blood borne infections as well as pose an avoidable financial burden on patients. Perceptions in rural Cambodia that non-illicit medical drug injections are the best quality of medical care have resulted in a high proportion of the population seeking these injections across medical conditions. As private providers have a higher propensity to offer injections, patients pursue more expensive care contributing to greater financial burden on patients. This study aimed to use an educational intervention to improve participant knowledge about injections and health insurance in order to build informed trust in safer injection practices and health insurance. Using a quasi-experimental study design, villages in rural Cambodia were randomly assigned to ...

  • Technology and corruption: experimental evidence from the introduction of tax e-filing in Tajikistan
    Last registered on November 17, 2017

    Corruption, tax evasion and ineffective revenue collection mechanisms can hinder a country’s economic growth. Designing more efficient and transparent tax administration systems is thus an important policy challenge, particularly for low income countries. Tajikistan, one of the lowest ranking countries on Ease of Paying Taxes (178/189) and Ease of Doing Business (143/189), implemented a reform of its tax system in 2012 to allow tax payers file tax returns electronically (e-filing). E-filing can streamline tax payments by eliminating long submission waiting queues and by reducing corruption, with fewer direct interactions between taxpayers and tax officials. However, few years after this reform, e-filing take-up rate remained low. This study aims to provide empirical evidence on the fact...

  • Distributional preferences over health and income
    Last registered on November 17, 2017

    The Gini coefficient and the concentration index for socio-economic health inequality are two widely used measures of inequality in their respective fields. Both indices implicitly make the value judgment that individuals that are equally far away from the median are weighted equally when the index is calculated. The generalized Gini coefficient (Donaldson and Weymark, 1980) and the extended concentration index (Wagstaff, 2002) both generalize the standard indices so that the value judgment enters as a separable variable that can be adjusted e.g. giving relatively higher weight to the disadvantaged part of the distribution. The aim of our study is to use surveys to elicit this inequality aversion parameter with respect to income inequality and socio-economic inequality in health. Assumi...

  • Leveraging Patients' Social Networks to Overcome Tuberculosis Under-detection in India
    Last registered on November 17, 2017

    In India alone, it is estimated that 3.5 million people suffer from Tuberculosis. The under-detection of TB represents a key challenge for health officials in developing countries because the success of any treatment program rests crucially on identifying those who have the disease. We propose to evaluate an approach with the potential to augment and strengthen the WHO’s global strategy for community engagement in the fight against TB. We will explore the use of financial incentives to encourage referrals, and we will focus on a specific community group with unique potential to generate referrals; current patients under treatment for TB. We will conduct a randomized controlled trial to compare the effects of different types of financial incentives to encourage TB patients to refer peopl...

  • Upgrading Management Technology in Colombia
    Last registered on November 16, 2017

    The key objectives of this research are i) to test whether a scalable and cost-effective approach to closing the gap in management practices between developing and more developed countries can be implemented; and ii) to measure the impact of closing this management gap on firm productivity and profitability. It will do this by means of a randomized experiment in Colombia, which will allocate firms into three groups: a control group who just receive a diagnostic on their management practices, an individualized treatment group who receive one-on-one consulting to improve 5 different processes: Logistics, Human Resources, Finance, Marketing and Sales, and Production; and a treatment group in which management improvements will be implemented in a small group setting, analogous to agricultur...

  • Job Networks and Gender in Malawi
    Last registered on November 14, 2017

    This paper uses a field experiment in Malawi to show that highly skilled women are systematically disadvantaged by referral-based hiring, highlighting another channel behind gender disparities in the labor market. The main reason is that men systematically refer few women. We show this is not because there are too few women who are qualified for the job. Instead we show that factors which are not related to women's qualifications but are instead due to the social environment - such as men having worse information about women’s abilities and receiving more social benefits from referring men - play a role. Firms cannot just rely on their female employees either since in this context, at least, women referred lower quality candidates.

  • Effects of Cooperative Learning in Secondary Schools in Karnataka, India
    Last registered on November 14, 2017

    Past studies suggest that effective policy interventions to improve learning, particularly for first generation learners, must address in some measure the psychological dimensions of inequality which might affect these students. Our study aims to study policy interventions which take into account these psychological factors, through randomized experiments in education. Randomized evaluations allow us to test alternative treatments that can increase learning as well as student satisfaction and motivation. In particular, we are interested in understanding how a powerful alternative pedagogic method of group learning (cooperative learning) can affect learning outcomes among students, with particular focus given to students from disadvantaged backgrounds. Our study will make a significan...
