The Short-Run Impact of Import Bans on Poverty: The Case of Nigeria (2008–2012)
(Published by Oxford University Press on behalf of the World Bank, 2018-06)The Nigerian government uses food import prohibition as part of policies that seeks to protect existing domestic producers and reduce the country's dependence on imports. This paper argues that such policies have negative effects on net consumers of such products due to higher prices. With 70 percent of poor households' budget spent on food, and about 13 percent of the total budget devoted to products subject to import bans, poor households are vulnerable to such trade policies. Prices of some import prohibited food products are found to be higher than what they would be in the absence of such bans. The elimination of import bans is estimated to reduce national poverty rates by as much as 2.6 percentage points. -

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. -

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.
