Are New Secondary Schools Built Where They Are Needed Most in Uganda? Comparing Catholic with Public and Other Private Schools
(Taylor and Francis, 2020-06-16)Low income countries in sub-Saharan Africa are confronted with a major challenge in terms of expanding access to secondary education. This is also the case in Uganda. This article considers two questions. First, where should new secondary schools be built if the aim is to reduce geographic disparities in access? Second, have new schools, and in particular faith-based schools, been built in the areas that need schools the most? The analysis considers Catholic as well as public and other private schools. Results suggest that new schools are often not located in the areas that need them the most. -

Utilization of Health Care and Burden of Out-of-Pocket Health Expenditure in Zimbabwe: Results from a National Household Survey
(Taylor and Francis, 2018-11-06)In the last decade, Zimbabwe has undertaken substantial changes and implemented new initiatives to improve health system performance and services delivery, including results-based financing in rural health facilities. This study aims to examine the utilization of health services and level of financial risk protection of Zimbabwe’s health system. Using a multistage sampling approach, 7,135 households with a total of 32,294 individuals were surveyed in early 2016 on utilization of health services, out-of-pocket (OOP) health expenditure, and household consumption (as a measure of living standards) in 2015. The study found that the outpatient visits were favorable to the poor but the poorest had less access to inpatient care. In 2015, household OOP expenditure accounted for about one quarter of total health expenditure in Zimbabwe and 7.6% of households incurred catastrophic health expenditure (CHE). The incidence of CHE was 13.4% in the poorest quintile in comparison with 2.8% in the richest. Additionally, 1.29% of households fell into poverty due to health care–related expenditures. The study suggests that there are inequalities in utilization of health services among different population groups. The poor seeking inpatient care are the most vulnerable to CHE. -

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. -

Integrating Social Protection and Early Childhood Development: Open Trial of a Family Home-Visiting Intervention, Sugira Muryango
(Taylor and Francis, 2018-04-24)A pre-post design with 6–13-month follow-up assessed the feasibility and acceptability of a home-visiting intervention to promote early childhood development, improve parenting and shared decision-making, and reduce violence in impoverished Rwandan households. Twenty vulnerable families with a child 36-months or younger enrolled in Sugira Muryango. Measures of parenting, home environment, family-violence, decision-making, and health-status were administered at pre/post and follow-up. Families reported high satisfaction post-intervention. OMCI scores improved for 4.8% of mother-child dyads at post-intervention and 19.0% at follow-up, while 9.5% of dyads showed declines at both times. HOME Inventory scores improved for 9.5% and 14.3% of dyads at post-intervention and follow-up respectively and declined for 4.8% and 0.0%. Indicators for equal decision-making and child dietary-diversity improved at post-intervention and follow-up. Fewer mothers believed physical punishment was necessary at follow-up. Sugira Muryango shows promise for improving parenting, beliefs about harsh punishment, child nutritional status, and shared decision-making among vulnerable families. -

All that Glitters is not Gold: Polarization Amid Poverty Reduction in Ghana
(Elsevier, 2018-02)Ghana is an exceptional case in the Sub-Saharan Africa (SSA) landscape. Together with a handful of other countries, Ghana offers the opportunity to analyze the distributional changes in the past two decades, since four comparable household surveys are available. In addition, unlike many other countries in SSA, Ghana’s rapid growth translated into fast poverty reduction. A closer look at the distributional changes that occurred in the same period, however, suggests less optimism. The present paper develops an innovative methodology to analyze the distributional changes that occurred and their drivers, with a high degree of accuracy and granularity. Looking at the results from 1991 to 2012, the paper documents how the distributional changes over time hollowed out the middle of the Ghanaian household consumption distribution and increased the concentration of households around the highest and lowest deciles; there was a clear surge in polarization indeed. When looking at the drivers of polarization, household characteristics, educational attainment, and access to basic infrastructure all tended to increase over time the size of the upper and lower tails of the consumption distribution and, as a consequence, the degree of polarization. -

Micro-Level Welfare Impacts of Agricultural Productivity: Evidence from Rural Malawi
(Taylor and Francis, 2018)This article analyses the micro-level welfare impacts of agricultural productivity using a two-wave nationally representative, panel data from rural Malawi. Welfare is measured by various dimensions of poverty and food insecurity; and agricultural productivity is measured by maize yield and value of crop output per hectare. The poverty measures included per capita consumption expenditure, relative deprivation in terms of per capita consumption expenditure, poverty gap and severity of poverty; and the measures of food insecurity included caloric intake and relative deprivation in terms of caloric intake. Depending on the measure of welfare, the impact of agricultural productivity was estimated with a household fixed effects estimator, a two-part estimator or a correlated-random effect ordered probit estimator. The results indicate that growth in agricultural productivity has the expected welfare-improving effect. In terms of economic magnitude, however, both the direct effect and economy-wide spillover effect (in the non-farm sector) of a percentage increase in agricultural productivity on the poverty and food security measures are small. Efforts to effectively improve the welfare of rural agricultural households should therefore go beyond merely increasing agricultural (land) productivity. -

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. -

When the Centre Cannot Hold: Patterns of Polarization in Nigeria
(Wiley, 2017-12)This paper advances the hypothesis that Nigeria is going through a process of economic polarization. The notion of polarization is concerned with the disappearance or non-consolidation of the middle class, which occurs when there is a tendency to concentrate in the tails, rather than the middle, of the income/consumption distribution. This paper uses newly available data and the relative distribution methodology (Handcock and Morris, 1998, 1999) to present new results on polarization. The findings confirm the sharp increase of polarization. Compared to 2003, the distribution of consumption has become more concentrated in upper and lower deciles in 2013, while the middle deciles have thinned. A between-group analysis shows the emergence of a macro-regional gap: while the South-South and South-West regions contribute mainly to polarization in the upper tail, households in the North East and North West zones—the conflict-stricken areas—are more likely to fall in the lower national deciles. -

No Condition Is Permanent: Middle Class in Nigeria in the Last Decade
(Taylor and Francis, 2017-09-21)The economic debate on the existence and definition of the middle class has become particularly lively in many developing countries. Building on a recently developed framework called the Vulnerability Approach to Middle Class (VAMC) to define the middle class, this paper tries to estimate the size of the Nigerian middle class in a rigorous quantitative manner and to gauge its evolution over time. Using the VAMC method, the middle class group can be defined residually from the vulnerability analysis as those for which the probability of falling into poverty is below a certain threshold. The results show that there has been considerable improvement in the size of the Nigerian middle class from 13 per cent in 2003/4 to 19 per cent in 2012/13. However, the rate has been slower than expected given the high growth rates experienced in the country over the same period. The results also paint a heterogeneous picture of the middle class in Nigeria with large spatial differences. The southern regions have a higher share and experienced more growth of the middle class compared with the northern regions. -

Vulnerability to Drought and Food Price Shocks: Evidence from Ethiopia
(Elsevier, 2017-08)While the measurement and determinants of poverty have been widely studied, vulnerability, or the threat of future poverty, has been more difficult to investigate due to data paucity. We combine nationally representative household data with objective drought and price information to quantify and investigate causes of vulnerability to poverty in Ethiopia. Previous estimates have relied on self-reported shocks and variation in outcomes within a survey, which is inadequate for shocks such as weather and prices that vary more across time than space. We used historical distributions of climate and price shocks in each district to simulate the probable distribution of future consumption for individual households and use these quantify vulnerability to poverty. We find that many Ethiopians are unable to protect their consumption against lack of rainfall and sudden increases in food prices. A moderate drought causes a 9% reduction in consumption for many rural households and recent high inflation has caused a 14% reduction in the consumption of uneducated households in urban areas. We also find that the vulnerability of rural households is considerably higher than that of urban households, despite realized poverty rates being fairly similar. This reflects the fact that the household survey in 2011 was conducted during a year of good rainfall but rapid food price inflation. The results highlight the need for caution in using a snapshot of poverty to target programs, as underlying rates of vulnerability can be quite different from the poverty rate captured at one point in time. The results also suggest that significant welfare gains can be made from risk management in both rural and urban areas.
