  2. Female Empowerment: Further Evidence From a Commitment Savings Product in the Philippines

    Female "empowerment" has increasingly become a policy goal, both as an end to itself and as a means to achieving other development goals. Microfinance in particular has often been argued, but not without controversy, to be a tool for empowering women. Here, using a randomized controlled trial, we examine whether access to and marketing of an individually held commitment savings product lead to an increase in female decision-making power within the household. We find positive impacts, particularly for women who have below median decision-making power in the baseline, and we find this leads to a shift toward female-oriented durable goods purchased in the household.

  3. Finding Missing Markets (and a Disturbing Epilogue): Evidence from an Export Crop Adoption and Marketing Intervention in Kenya

    Farmers may grow crops for local consumption despite more profitable export options. DrumNet, a Kenyan NGO that helps small farmers adopt and market export crops, conducted a randomized trial to evaluate its impact. DrumNet services increased production of export crops and lowered marketing costs, leading to a 32% income gain for new adopters. The services collapsed one year later when the exporter stopped buying from DrumNet because farmers could not meet new EU production requirements. Farmers sold to other middlemen and defaulted on their loans from DrumNet. Such experiences may explain why farmers are less likely to adopt export crops.

  4. Spousal Control and Intra-Household Decision Making: An Experimental Study in the Philippines

    Using an experimental design I elicit causal effects of spousal observability and communication on financial choices of married individuals in the Philippines. Making choices public moves men from putting money into their own account to consumption; communication with their spouse drives men to put income in their wives' account. The strong effect on men but not women of information and communication appears to be driven not as much by gender as by control: men whose wives control household savings are much more likely to exhibit this treatment effect, and women whose husbands control savings exhibit the same pattern as men. These results suggest that existing household models and policies are incomplete without taking into account the bargaining process and, in particular, the way in which this process interacts with underlying control structures in the household.

Working Papers

  1. Information and Subsidies: Complements or Substitutes?

    Does providing information about a product affect the impact of price subsidies on purchases of new or unfamiliar products? This question is particularly relevant for the introduction of health products in developing countries where consumers may be uncertain about product quality and price subsidies are common policy instruments. Through a field experiment selling an unfamiliar health product in Zambia, we find that providing precise information about product specifications significantly increases the impact of the price subsidy on take-up. Taken alone, the information manipulation has no significant impact on demand while the price subsidy substantially increases demand. However, evaluation of either intervention in isolation fails to capture the significant complementarity between the two.

  4. No Margin, No Mission? A Field Experiment on Incentives for Pro-Social Tasks

    A substantial body of research investigates the effect of pay for performance in firms, yet less is known about the effect of non-financial rewards, especially in organizations that hire individuals to perform tasks with positive social spillovers. We conduct a field experiment in which agents recruited by a public health organization to sell condoms are randomly allocated to four groups. Agents in the control group are hired as volunteers, whereas agents in the three treatment groups receive a small monetary margin on each pack sold, a large margin, and a non-financial reward, respectively. The analysis yields three main findings. First, non-financial rewards are more effective at eliciting effort than either financial rewards or the volunteer contract, and are also the most cost-effective of the four schemes. Second, non-financial rewards leverage intrinsic motivation and, contrary to existing laboratory evidence, financial incentives do not appear to crowd it out. Third, the responses to both types of incentives are stronger when their relative value is higher. Indeed, financial rewards are effective at motivating the poorest agents, and non-financial rewards are more effective when the peer group is larger. Overall, the findings demonstrate the power of non-financial rewards to motivate agents in settings where there are limits to the use of financial incentives.

  5. Evaluating the Effects of Large-Scale Health Interventions in Developing Countries: The Zambian Malaria Initiative

    Since 2003, Zambia has been engaged in a large-scale, centrally coordinated national anti-malaria campaign which has become a model in sub-Saharan Africa. This paper aims at quantifying the individual and macro level benefits of this campaign, which involved mass distribution of insecticide treated mosquito nets, intermittent preventive treatment for pregnant women, indoor residual spraying, rapid diagnostic tests, and artemisinin-based combination therapy. We discuss the timing and regional coverage of the program and critically review the available health and program rollout data. To estimate the health benefits associated with the program rollout, we use both population based morbidity measures from the Demographic and Health Surveys and health facility based mortality data as reported in the national Health Management Information System. While we find rather robust correlations between the rollout of bed nets and subsequent improvements in our health measures, the link between regional spraying and individual level health appears rather weak in the data.

  3. Community Health Workers in Zambia: Incentive Design and Management

    This case examines the various considerations relevant to selecting and compensating workers in a context where their work involves a pro-social component. This is relevant to not only health care in Zambia, but to NGO and public sector workers who are both motivated by the mission of their positions and the remuneration. Zambia was facing a healthcare human resource crisis with less than half of the healthcare workers needed to meet health needs. Yet, it was simultaneously burdened by high incidence of diseases such as HIV/AIDS, TB, malaria, malnutrition, and respiratory and diarrheal diseases. The Zambian Ministry of Health (MoH) realized that in the short term, it would be impossible to train the number of doctors and nurses needed to fill this gap. Thus, they were considering incorporating the primarily volunteer community health worker (CHW) force into salaried health workers of the MoH. Given the high level of personal commitment and dedication combined with the proper education and skill needed to be an effective community health worker, the MoH was struggling to identify the best strategy to recruit and retain motivated and capable CHWs.

  4. Uptake of Malaria Rapid Diagnostic Tests

    This case describes barriers to adoption of malaria rapid diagnostic tests in Zambia and highlights the importance of understanding end users in promoting product adoption. Rapid diagnostic tests (RDTs) are simple, easy-to-use tools that provide a relatively reliable, inexpensive way to confirm diagnoses of malaria. In addition to ensuring that patients' febrile illnesses are properly diagnosed and treated, confirming malaria diagnoses has broader public health benefits, including promoting the efficient use of limited malaria medications and preventing increased resistance to first-line malaria treatment. However, despite the evident potential benefits of RDTs, many clinicians in Zambia do not use them or simply ignore their results. Why don't they trust these tools, and what can be done to improve adoption? Various barriers to uptake and methods to overcome these challenges are explored, with broad implications for technology adoption and health policy. A particular emphasis is placed on the role of behavioral preferences.

  5. Oral Rehydration Therapy

    This case highlights the puzzlingly high rate of diarrhea-related child mortality in developing countries despite the existence of a simple, effective treatment: oral rehydration therapy (ORT). ORT treated extreme dehydration caused by diarrhea, which was a leading cause of death among young children in developing countries, particularly in Africa and Asia. Heralded in the 1970s as one of the most Important medical advancements of the 20th century, ORT contributed to a reduction in diarrhea-related child deaths from roughly 4.5 million in 1980 to 1.5 million in 2000. Yet for reasons unclear to the global public health community, the mortality rate stalled at around 1.5 million, where it remained in 2010. In presenting the problem of diarrhea-related death, the solution represented by ORT, and the various factors potentially influencing ORT utilization, the case allows students to analyze the possible causes of low ORT utilization and potential measures to address them.

  6. Evaluating Microsavings Programs: Green Bank of the Philippines (A)

    Green Bank of the Philippines was known for its product innovation and its ability to bring new products to market. In 2002, Green Bank designed an untested commitment savings product that both gave individuals access to formal savings and helped them commit to reaching their savings goals. Omar Andaya, the Green Bank president, must decide how to evaluate the success of this product. The management team at Green Bank discusses various evaluation methods, including a formal quantitative impact evaluation using a randomized control trial (RCT), and the value an impact assessment brings to the Bank. In particular, they grapple with the question of how success is measured for a product both for the bank and for its clients. The case highlights the issues an organization must consider before deciding to do an impact assessment as well as common design challenges.

  7. Deworming Kenya: Translating Research into Action (A)

    Karen Levy and her colleague, Margaret Ndanyi, have spent the last six months planning and preparing for a national Kenyan program to target school children most at risk for parasitic worm infection. One week after its launch, the program seemed to be going well but Ndanyi and Levy knew that it still needed to be administered in almost 40 districts at thousands of schools. They wondered: Would they meet their goal of deworming over three million school children before the end of the fiscal year on June 30, 2009? Would they be able to do it for less than $0.50 per child?

  9. PSI: Social Marketing Clean Water

    Senior management at PSI, arguably the world's largest and most successful social marketer with impressive achievements in the field of family planning, HIV/AIDS, and malaria prevention must determine what to do about their slow-to-take-off clean water initiative. PSI's point-of-use products offered effective protection against water-borne diseases, especially diarrhea, yet the organization found it hard to attract donor funds to sustain the initiative. Its managers must determine how to alter their strategy going forward.
