The Challenge of Measuring Hunger
(World Bank, Washington, DC, 2014-01)There is widespread interest in the number of hungry people in the world and trends in hunger. Current global counts rely on combining each country's total food balance with information on distribution patterns from household consumption expenditure surveys. Recent research has advocated for calculating hunger numbers directly from these same surveys. For either approach, embedded in this effort are a number of important details about how household surveys are designed and how these data are then used. Using a survey experiment in Tanzania, this study finds great fragility in hunger counts stemming from alternative survey designs. As a consequence, comparable and valid hunger numbers will be lacking until more effort is made to either harmonize survey designs or better understand the consequences of survey design variation. -

Development, Modernization, and Son Preference in Fertility Decisions
(World Bank, Washington, DC, 2008-09)A family preference for sons over daughters may manifest itself in different ways, including higher mortality, worse health status, or lower educational attainment among girls. This study focuses on one measure of son preference in the developing world, namely the likelihood of continued childbearing given the gender composition of existing children in the family. The authors use an unusually large data set, covering 65 countries and approximately 5 million births. The analysis shows that son preference is apparent in many regions of the developing world and is particularly large in South Asia and in the Eastern Europe and Central Asia region. Modernization does not appear to reduce son preference. For example, in South Asia son preference is larger for women with more education and is increasing over time. The explanation for these patterns appears to be that latent son preference in childbearing is more likely to manifest itself when fertility levels are low. As a result of son preference, girls tend to grow up with significantly more siblings than boys do, which may have implications for their wellbeing if there are quantity-quality trade-offs that result in fewer material and emotional resources allocated to children in larger families. -

Psychological Health Before, During, and After an Economic Crisis : Results from Indonesia, 1993 - 2000
(World Bank, Washington, DC, 2007-11)The 1997 Indonesian financial crisis resulted in severe economic dislocation and political upheaval, and the detrimental consequences for economic welfare, physical health, and child education have been previously established in numerous studies. We also find the crisis adversely impacted population psychological well-being. We document substantial increases in several different dimensions of psychological distress among male and female adults across the entire age distribution over the crisis period. In addition, the imprint of the crisis can be seen in the differential impacts of the crisis on low education groups, the rural landless, and residents in those provinces that were hit hardest by the crisis. Elevated levels of psychological distress persist even after indicators of economic well-being such as household consumption had returned to pre-crisis levels suggesting long-term deleterious effects of the crisis on the psychological well-being of the Indonesian population. -

Aggregate Income Shocks and Infant Mortality in the Developing World
(World Bank, Washington, DC, 2007-09)The diffusion of cost-effective life saving technologies has reduced infant mortality in much of the developing world. Income gains may also play a direct, protective role in ensuring child survival, although the empirical findings to date on this issue have been mixed. This paper assembles data from Demographic and Health Surveys (DHS) in 59 countries to analyze the relationship between changes in per capita GDP and infant mortality. The authors show that there is a strong, negative association between changes in per capita GDP and infant mortality- in a first-differenced specification the implied elasticity of infant mortality with respect to per capita GDP is approximately -0.56. In addition to this central result, two findings are noteworthy. First, although there is some evidence of changes in the composition of women giving birth during economic upturns and downturns, the observed changes in infant mortality are not a result of mothers with protective characteristics timing fertility to correspond with the business cycle. Second, the association between infant mortality and per capita GDP is particularly pronounced for periods of large contractions in GDP, suggesting the inability of developing country households or health systems (or both) to smooth resources. Simple back-of-the-envelope calculations using the estimates suggest that there may have been more than 1 million "excess" deaths in the developing world since 1980 as a result of large, negative contractions in per capita GDP. -

Mental Health Patterns and Consequences : Results from Survey Data in Five Developing Countries
(World Bank, 2009-02-28)The social and economic consequences of poor mental health in the developing world are presumed to be significant, yet remain underresearched. This study uses data from nationally representative surveys in Bosnia and Herzegovina, Indonesia, and Mexico and from special surveys in India and Tonga to show similar patterns of association between mental health and socioeconomic characteristics. Individuals who are older, female, widowed, and report poor physical health are more likely to report worse mental health. Individuals living with others with poor mental health are also significantly more likely to report worse mental health themselves. In contrast, there is little observed relation between mental health and consumption poverty or education, two common measures of socioeconomic status. Indeed, the results here suggest instead that economic and multidimensional shocks, such as illness or crisis, can have a greater impact on mental health than poverty. This may have important implications for social protection policy. Also significant, the associations between poor mental health and lower labor force participation (especially for women) and more frequent visits to health centers suggest that poor mental health can have economic consequences for households and the health system. Mental health modules could usefully be added to multipurpose household surveys in developing countries. Finally, measures of mental health appear distinct from general subjective measures of welfare such as happiness. -

Psychological Health Before, During, and After an Economic Crisis : Results from Indonesia, 1993–2000
(World Bank, 2009-02-28)The 1997 Indonesian financial crisis resulted in severe economic dislocation and political upheaval. Previous studies have established the detrimental consequences for economic welfare, physical health, and child education. The crisis also affected the psychological well-being of the Indonesian people. Comparing responses of the same individuals interviewed before and after the crisis, this study documents substantial increases in several dimensions of psychological distress among men and women across the age distribution. It shows larger impacts of the economic crisis on the more vulnerable groups, including those with low education, the rural landless, urban residents, and those in provinces most affected by the crisis. Elevated psychological distress persists even after the economy returns to precrisis levels, suggesting that the deleterious effects of the crisis may persist longer on the psychological well-being of the Indonesian population than on standard measures of economic well-being. -

Strengthening Malaria Service Delivery through Supportive Supervision and Community Mobilization in an Endemic Indian Setting : An Evaluation of Nested Delivery Models
(World Bank, Washington, DC, 2014-06)Malaria continues to be a prominent global public health challenge, in part because of the slow population adoption of recommended preventive and curative behaviors. This paper tests the effectiveness of two service delivery models designed to promote recommended behaviors, including prompt treatment seeking for febrile illness, in Odisha India. The tested modules include supportive supervision of community health workers and community mobilization promoting appropriate health seeking. Program effects were identified through a randomized cluster trial comprising 120 villages from two purposively chosen malaria-endemic districts. Significant improvements were measured in the reported utilization of bed nets in both intervention arms vis-à-vis the control. Although overall rates of treatment seeking were equal across the study arms, treatment seeking from community health workers was higher in both intervention arms and care seeking from trained providers also increased with a substitution away from untrained providers. Further, fever cases in both treatments were more likely to have received timely medical treatment (within 24 hours) from a skilled provider. The study arm with supportive supervision was particularly effective in shifting care seeking to community health workers and ensuring prompt diagnosis and treatment. A community-based intervention combining the supportive supervision of community health workers with intensive community mobilization can be effective in shifting care seeking and increasing preventive behavior, and thus may be used to strengthen the national malaria control program. -

Does Involvement of Local NGOs Enhance Public Service Delivery? Cautionary Evidence from a Malaria-Prevention Evaluation in India
(World Bank, Washington, DC, 2014-06)Using data from an experimental supportive intervention to India's malaria control program, this paper studies the impact of leveraging local non-state capacity to promote mosquito net usage and recommended fever care-seeking patterns. The supportive activities were conducted simultaneously by three nongovernmental organizations in two endemic districts in the state of Orissa. The study finds that program impact varied significantly by location. Examining three potential sources of this variation (differential population characteristics, differential health worker characteristics, and differential implementer characteristics), the analysis provides evidence that both population and nongovernmental organization characteristics significantly affected the success of the program. The paper discusses these findings as they relate to the external validity of development policy evaluations and, specifically, for the ability of the health system to benefit from limited non-state capacity in under-resourced areas. -

Health Information, Treatment, and Worker Productivity : Experimental Evidence from Malaria Testing and Treatment among Nigerian Sugarcane Cutters
(World Bank Group, Washington, DC, 2014-11)Agricultural and other physically demanding sectors are important sources of growth in developing countries but prevalent diseases such as malaria adversely impact the productivity, labor supply, and choice of job tasks among workers by reducing physical capacity. This study identifies the impact of malaria on worker earnings, labor supply, and daily productivity by randomizing the temporal order at which piece-rate workers at a large sugarcane plantation in Nigeria are offered malaria testing and treatment. The results indicate a significant and substantial intent to treat effect of the intervention -- the offer of a workplace-based malaria testing and treatment program increases worker earnings by approximately 10 percent over the weeks following the offer. The study further investigates the effect of health information by contrasting program effects by workers' revealed health status. For workers who test positive for malaria, the treatment of illness increases labor supply, leading to higher earnings. For workers who test negative, and especially for those workers most likely to be surprised by the healthy diagnosis, the health information also leads to increased earnings via increased productivity. Possible mechanisms for this response include selection into higher return tasks within the plantation as a result of changes in the perceived cost of effort. A model of the worker labor decision that allows health expectations partly to determine the supply of effort suggests that, in endemic settings with poor quality health services, inaccurate health perceptions may lead workers to suboptimal labor allocation decisions. The results underline the importance of medical treatment, but also of access to improved information about one's health status, as the absence of either may lead workers to deliver lower effort in lower return jobs. -
