Improving Effective Coverage in Health: Do Financial Incentives Work?
(Washington, DC: World Bank, 2022-05-11)In many low- and middle-income countries, health coverage has improved dramatically in the last two decades, but health outcomes have not. As such, effective coverage -- a measure of service delivery that meets a minimum standard of quality -- remains unacceptably low. This Policy Research Report examines one specific policy approach to improving effective coverage: financial incentives in the form of performance-based financing (PBF) or financial incentives to health workers on the front lines. The report draws on a rich set of rigorous studies and new analysis. When compared to business-as-usual, in low-income settings with centralized health systems PBF can result in substantial gains in effective coverage. However, the relative benefits of PBF are less clear when it is compared to two alternative approaches, decentralized facility financing which provides operating budget to frontline health services with facility autonomy on allocation, and demand-side financial support for health services (i.e., conditional cash transfers and vouchers). While PBF often results in improvements on the margins, closing the substantial gaps in effective health coverage is not yet within reach for many countries. Nonetheless, there are important lessons learned and experiences from the roll-out of PBF over the last decade which can guide health policies into the future. -

Disruptions in Maternal and Child Health Service Utilization during COVID-19: Analysis from Eight Sub-Saharan African Countries
(Oxford University Press, 2021-06-19)The coronavirus-19 pandemic and its secondary effects threaten the continuity of essential health services delivery, which may lead to worsened population health and a protracted public health crisis. We quantify such disruptions, focusing on maternal and child health, in eight sub-Saharan countries. Service volumes are extracted from administrative systems for 63 954 facilities in eight countries: Cameroon, Democratic Republic of Congo, Liberia, Malawi, Mali, Nigeria, Sierra Leone and Somalia. Using an interrupted time series design and an ordinary least squares regression model with facility-level fixed effects, we analyze data from January 2018 to February 2020 to predict what service utilization levels would have been in March–July 2020 in the absence of the pandemic, accounting for both secular trends and seasonality. Estimates of disruption are derived by comparing the predicted and observed service utilization levels during the pandemic period. All countries experienced service disruptions for at least 1 month, but the magnitude and duration of the disruptions vary. Outpatient consultations and child vaccinations were the most commonly affected services and fell by the largest margins. We estimate a cumulative shortfall of 5 149 491 outpatient consultations and 328 961 third-dose pentavalent vaccinations during the 5 months in these eight countries. Decreases in maternal health service utilization are less generalized, although significant declines in institutional deliveries, antenatal care and postnatal care were detected in some countries. There is a need to better understand the factors determining the magnitude and duration of such disruptions in order to design interventions that would respond to the shortfall in care. Service delivery modifications need to be both highly contextualized and integrated as a core component of future epidemic response and planning. -

The Intergenerational Mortality Tradeoff of COVID-19 Lockdown Policies
(World Bank, Washington, DC, 2021-05)In lower-income countries, the economic contractions that accompany lockdowns to contain the spread of COVID-19 can increase child mortality, counteracting the mortality reductions achieved by the lockdown. To formalize and quantify this effect, this paper builds a macro-susceptible-infected-recovered model that features heterogeneous agents and a country-group-specific relationship between economic downturns and child mortality, and calibrate it to data for 85 countries across all income levels. The findings show that in low-income countries, a lockdown can potentially lead to 1.76 children’s lives lost due to the economic contraction per COVID-19 fatality averted. The ratio stands at 0.59 and 0.06 in lower-middle and upper-middle income countries, respectively. As a result, in some countries lockdowns can actually produce net increases in mortality. In contrast, the optimal lockdown that maximizes the present value of aggregate social welfare is shorter and milder in poorer countries than in rich ones, and never produces a net mortality increase. -

Financial Incentives to Increase Utilization of Reproductive, Maternal, and Child Health Services in Low- and Middle-Income Countries: A Systematic Review and Meta-Analysis
(World Bank, Washington, DC, 2021-10)Financial incentives for health providers and households are increasingly used to improve reproductive, maternal, and child health service coverage in low- and middle-income countries. This study provides a quantitative synthesis of their effectiveness. A systematic review was conducted of the effects of performance-based financing, voucher, and conditional cash transfer programs on six reproductive, maternal, and child health service indicators, with eligible evidence coming from randomized controlled trials and studies using double-difference, instrumental variables, and regression discontinuity designs. Four literature searches were conducted between September 2016 and March 2021 using seven academic databases, Google Scholar, development agency and think tank websites, and previous systematic reviews. Random effects meta-analysis was used to obtain mean effect sizes. From 58 eligible references 212 impact estimates were extracted, which were synthesized into 130 program-specific effect sizes. Financial incentives increase coverage of all considered reproductive, maternal, and child health indicators, but mean effects sizes are of modest magnitude. Effect size heterogeneity is typically low to moderate, and there is no indication that study bias risk, baseline indicator levels, or a combination of provider- and household-level incentives impact effect sizes. There is, however, weak evidence that mean effect sizes are somewhat smaller for performance-based financing than for voucher and conditional cash transfer programs, and that the increase in income, rather than the incentive itself, drives coverage improvements. Financial incentives improve reproductive, maternal, and child health service coverage. If future research confirms the preliminary finding that performance-based financing has smaller effects, voucher and conditional cash transfer programs are the preferred policy option among incentive interventions to achieve higher reproductive, maternal, and child health service coverage. The relative effectiveness and efficiency of incentives compared with unconditional increases of provider and household incomes, however, need to be studied further. -

The Distribution of Effort: Physical Activity, Gender Roles, and Bargaining Power in an Agrarian Setting
(World Bank, Washington, DC, 2021-04)The disutility of work, often summarily described as effort, is a primal component of economic models of worker and consumer behavior. However, empirical applications that measure effort, especially those that assess the distribution of effort across known populations, are historically scarce. This paper explores intra-household differences in physical activity in a rural agrarian setting. Physical activity is captured via wearable accelerometers that provide a proxy for physical effort expended per unit of time. In the study setting of agricultural households in Malawi, men devote significantly more time to sedentary activities than women (38 minutes per day), but also spend more time on moderate-to-vigorous activities (16 minutes). Using standardized energy expenditure as a summary measure for physical effort, women exert marginally higher levels of physical effort than men. However, gender differences in effort among married partners are strongly associated with intra-household differences in bargaining power, with significantly larger husband-wife effort gaps alongside larger differences in age and individual land ownership as well as whether the couple lives as part of a polygamous union. Physical activity -- a proxy for physical effort, an understudied dimension of wellbeing -- exhibits an unequal distribution across gender in this population. -

How Many Infants May Have Died in Low-Income and Middle-Income Countries in 2020 Due to the Economic Contraction Accompanying the COVID-19 Pandemic? Mortality Projections Based on Forecasted Declines in Economic Growth
(BMJ Publishing Group, Ltd., 2021-08)While COVID-19 has a relatively small direct impact on infant mortality, the pandemic is expected to indirectly increase mortality of this vulnerable group in low-income and middle-income countries through its effects on the economy and health system performance. Previous studies projected indirect mortality by modelling how hypothesized disruptions in health services will affect health outcomes. We provide alternative projections, relying on modelling the relationship between aggregate income shocks and mortality. The findings underscore the vulnerability of infants to the negative income shocks such as those imposed by the COVID-19 pandemic. While efforts towards prevention and treatment of COVID-19 remain paramount, the global community should also strengthen social safety nets and assure continuity of essential health services. -

A Puzzle with Missing Pieces: Explaining the Effectiveness of World Bank Development Projects
(World Bank, Washington, DC, 2021-12)The identification of key determinants of aid effectiveness is a long-standing question in the development community. This paper reviews the literature on aid effectiveness at the project level and then extends the inquiry in a variety of dimensions with new data on World Bank investment project financing. It confirms that the country institutional setting and quality of project supervision are associated with project success, as identified previously. However, many aspects of the development project cycle, especially project design, have been difficult to measure and therefore under-investigated. The paper finds that project design, as proxied by the estimated value added of design staff, the presence of prior analytic work, and other specially collected measures, is a significant predictor of ultimate project success. These factors generally grow in predictive importance as the income level of the country rises. The results also indicate that a key determinant of the staff’s contribution is their experience with previous World Bank projects, but not other characteristics such as age, education, or country location. Key inputs to the project production process associated with subsequent performance are not captured in routine data systems, although it is feasible to do so. Further, the conceptualization and measurement of the success of project-based aid should be revisited by evaluative bodies to reflect a project’s theorized contribution to development outcomes. -

How Two Tests Can Help Contain COVID-19 and Revive the Economy
(World Bank, Washington, DC, 2020-04-08)Faced with COVID-19 (Coronavirus), countries are taking drastic action based on little information. Two tests can help governments shorten and soften economically costly suppression measures while still containing the novel coronavirus (COVID-19) pandemic. The first—a PCR assay—identifies people currently infected by testing for the presence of live virus in the subject. The second—an antibody test—identifies those rendered immune after being infected by searching for COVID-19-specific antibodies. The first test can help contain the disease because it facilitates the identification of infected persons, the tracing of their contacts, and isolation in the very early stages of an epidemic—or after a period of suppression, in case of a resurgent epidemic. The second can help us assess the extent of immunity in the general population or subgroups, to finetune social isolation and to manage health care resources. Wide application of the two tests could transform the battle against COVID-19 (Coronavirus), but implementing either on a large scale in developing countries presents challenges. The first test is generally available, but needs to be processed in adequately equipped laboratories with trained staff. The second test is easy to perform and can be processed quickly on the spot, but at this stage it is produced and available only on a limited basis in a few countries. This policy brief reviews the use of both tests, suggests strategies to target their use, and discusses the benefits and costs of such strategies. If PCR assay testing, together with tracing and isolation, helps reduce the duration of suppression measures by two weeks, and antibody testing allows one-fifth of the immune return to work early, the gain could be about 2 percent of national income, or about $8 billion for a country like the Philippines. Because the estimated economic benefits of the tests are likely to far outweigh the cost, the international community must help countries develop the capacity to process the first test and procure the second.
