The Role of Social Ties in Factor Allocation
(Published by Oxford University Press on behalf of the World Bank, 2019-10)We investigate whether social structure helps or hinders factor allocation using unusually rich data from the Gambia. Evidence indicates that land available for cultivation is allocated unequally across households; and that factor transfers are more common between neighbors, co-ethnics, and kinship-related households. Does this lead to the conclusion that land inequality is due to flows of land between households being impeded by social divisions? To answer this question, a novel methodology that approaches exhaustive data on dyadic flows from an aggregate point of view is introduced. Land transfers lead to a more equal distribution of land and to more comparable factor ratios across households in general. But equalizing transfers of land are not more likely within ethnic or kinship groups. In conclusion, ethnic and kinship divisions do not hinder land and labor transfers in a way that contributes to aggregate factor inequality. Labor transfers do not equilibrate factor ratios across households. But it cannot be ruled out that they serve a beneficial role, for example, to deal with unanticipated health shocks. -

Redistribution and Group Participation: Experimental Evidence from Africa and the UK
(Published by Oxford University Press on behalf of the World Bank, 2019-10)We investigate whether the prospect of redistribution hinders the formation of efficiency-enhancing groups. We conduct an experiment in a Kenyan slum, Ugandan villages, and a UK university town. We test, in an anonymous setting with no feedback, whether subjects join a group that increases their endowment but exposes them to one of three redistributive actions: stealing, giving, or burning. We find that exposure to redistributive options among group members operates as a disincentive to join a group. This finding obtains under all three treatments—including when the pressure to redistribute is intrinsic. However the nature of the redistribution affects the magnitude of the impact. Giving has the least impact on the decision to join a group, while forced redistribution through stealing or burning acts as a much larger deterrent to group membership. These findings are common across all three subject pools, but African subjects are particularly reluctant to join a group in the burning treatment, indicating strong reluctance to expose themselves to destruction by others. -

The Devil is in the Detail: Growth, Inequality and Poverty Reduction in Africa in the Last Two Decades
(Oxford University Press, 2019-08)The present paper, starting from evidence of low growth-to-poverty elasticity characterizing Africa, purports to identify the distributional changes that limited the pro-poor impact of the last two decades’ growth. Distributional changes that went undetected by standard inequality measures were not showing a clear pattern of inequality on the continent. By applying a new decomposition technique based on a non-parametric method—the ‘relative distribution’—we found a clear distributional pattern affecting almost all analysed countries. Nineteen out twenty four countries experienced a significant increase in polarization, particularly in the lower tail of the distribution, and this distributional change lowered the pro-poor impact of growth substantially. Without this unfavorable redistribution, poverty could have decreased in these countries by an additional five percentage points. -

Dynamics of Child Development: Analysis of a Longitudinal Cohort in a Very Low Income Country
(Published by Oxford University Press on behalf of the World Bank, 2019-02)Longitudinal patterns of child development and socioeconomic status are described for a cohort of children in Madagascar surveyed when 3–6 and 7–10 years old. Substantial wealth gradients were found across multiple domains: receptive vocabulary, cognition, sustained attention, and working memory. The results are robust to the inclusion of lagged outcomes, maternal endowments, measures of child health, and home stimulation. Wealth gradients are significant at ages 3–4, widen with age, and flatten out by ages 9–10. For vocabulary and sustained attention, the gradient grows steadily between ages three and six; for cognitive composite and memory of phrases, the gradient widens later (ages 7–8) before flattening out. These gaps in cognitive outcomes translate into equally sizeable gaps in learning outcomes. 12–18% of the predicted gap in early outcomes is accounted for by differences in home stimulation, even after controlling for maternal education and endowments. -

Progressive Pathway to Universal Health Coverage in Tanzania: A Call for Preferential Resource Allocation Targeting the Poor
(Taylor and Francis, 2018-10-31)Universal health coverage (UHC) can be a vehicle for improving equity, health outcomes, and financial well-being. After publication of the World Health Organization’s report in 2010, many countries declared their goal of achieving UHC. A key lesson from research evidence and country experience in implementation of pro-poor UHC is that public budget plays a crucial role in financing the poor. It has long been recognized that if a country wants to reduce the gap between the poor and non-poor, deprived groups should receive preferential allocation of health care resources to achieve more rapid improvements in their health. Based on a technical analysis of public funds allocation mechanisms in Tanzania, we argue that these mechanisms should prioritize the poor more explicitly and give them preferential treatment to close the gap with the non-poor in service utilization and health outcomes. -

Myth-Busting? Confronting Six Common Perceptions about Unconditional Cash Transfers as a Poverty Reduction Strategy in Africa
(Published by Oxford University Press on behalf of the World Bank, 2018-08)This paper summarizes evidence on six perceptions associated with cash transfer programming, using eight rigorous evaluations conducted on large-scale government unconditional cash transfers in sub-Saharan Africa under the Transfer Project. Specifically, it investigates if transfers: 1) induce higher spending on alcohol or tobacco; 2) are fully consumed (rather than invested); 3) create dependency (reduce participation in productive activities); 4) increase fertility; 5) lead to negative community-level economic impacts (including price distortion and inflation); and 6) are fiscally unsustainable. The paper presents evidence refuting each claim, leading to the conclusion that these perceptions—insofar as they are utilized in policy debates—undercut potential improvements in well-being and livelihood strengthening among the poor, which these programs can bring about in sub-Saharan Africa, and globally. It concludes by underscoring outstanding research gaps and policy implications for the continued expansion of unconditional cash transfers in the region and beyond. -

Inequality of Educational Opportunity: The Relationship between Access, Affordability, and Quality of Private Schools in Lagos, Nigeria
(Taylor and Francis, 2018)Using data from a census of private schools in one of Lagos, Nigeria’s administrative jurisdictions, this paper explores the linkages between a heterogeneous sector of private schools and issues of school access, affordability, quality, and ultimately social mobility for households at the bottom of the income distribution. Although a large private education market has buoyed Lagos’s growth towards near-universal primary enrolment, this heterogeneous school sector appears to be providing socially stratifying paths towards educational attainment. We apply Lucas’s theory of effectively maintained inequality to assess the extent to which access to higher quality education services within the private sector is determined by cost. We find that higher-cost private schools provide students with greater opportunities to study in institutions with higher quality inputs and increased potential for progression within the educational system. As such, it is highly likely that these schools are primarily accessible to students at the upper ends of the income distribution. -

Enrollment without Learning: Teacher Effort, Knowledge, and Skill in Primary Schools in Africa
(American Economic Association, 2017-11)School enrollment has universally increased over the last 25 years in low-income countries. Enrolling in school, however, does not assure that children learn. A large share of children in low-income countries complete their primary education lacking even basic reading, writing, and arithmetic skills. Teacher quality is a key determinant of student learning, but not much is known about teacher quality in low-income countries. This paper discusses an ongoing research program intended to help fill this void. We use data collected through direct observations, unannounced visits, and tests from primary schools in seven sub-Saharan African countries to answer three questions: How much do teachers teach? What do teachers know? How well do teachers teach? -

Blending Top-Down Federalism with Bottom-Up Engagement to Reduce Inequality in Ethiopia
(Elsevier, 2017-08)Donors increasingly fund interventions to counteract inequality in developing countries, where they fear it can foment instability and undermine nation-building efforts. To succeed, aid relies on the principle of upward accountability to donors. But federalism shifts the accountability of subnational officials downward to regional and local voters. What happens when aid agencies fund anti-inequality programs in federal countries? Does federalism undermine aid? Does aid undermine federalism? Or can the political and fiscal relations that define a federal system resolve the contradiction internally? We explore this paradox via the Promotion of Basic Services program in Ethiopia, the largest donor-financed investment program in the world. Using an original panel database comprising the universe of Ethiopian woredas (districts), the study finds that horizontal (geographic) inequality decreased substantially. Donor-financed block grants to woredas increased the availability of primary education and health care services in the bottom 20% of woredas. Weaker evidence from household surveys suggests that vertical inequality across wealth groups (within woredas) also declined, implying that individuals from the poorest households benefit disproportionately from increasing access to, and utilization of, such services. The evidence suggests that by combining strong upward accountability over public investment with enhanced citizen engagement on local issues, Ethiopia’s federal system resolves the instrumental dissonance posed by aid-funded programs to combat inequality in a federation. -

The Long-Run Economic Costs of AIDS : A Model with an Application to South Africa
(Published by Oxford University Press on behalf of the World Bank, 2006-04-11)Primarily a disease of young adults, Acquired Immuno Deficiency Syndrome (AIDS) imposes economic costs that could be devastatingly high in the long run by undermining the transmission of human capital the main driver of long-run economic growth across generations. AIDS makes it harder for victims' children to obtain an education and deprives them of the love, nurturing, and life skills that parents provide. These children will in turn find it difficult to educate their children, and so on. An overlapping generations model is used to show that an otherwise growing economy could decline to a low level subsistence equilibrium if hit with an AIDS type increase in premature adult mortality. Calibrating the model for South Africa, where the HIV prevalence rate is over 20 percent, simulations reveal that the economy could shrink to half its current size in about four generations in the absence of intervention. Programs to combat the disease and to support needy families could avert such a collapse, but they imply a fiscal burden of about 4 percent of Gross domestic product (GDP).
