• Summary & Policy Issues
Introduction • Six of the world’s ten fastest growing economies (20012010): In Sub-Saharan Africa • Global sentiment around SSA changed significantly • Current dominant global view: Africa is last of great untapped markets, ripe for rapid growth and development. • Supported by the Data: Six of the world’s ten fastest growing economies during 2001-2010 were in Sub-Saharan Africa* • Focus: Inequality Outcomes and their Determinants in SSA: – Understanding the Nature of Inequality in Africa – Evolution of Inequality in Africa – Key Drivers of Inequality in Africa *: The countries are Angola, Nigeria, Ethiopia, Chad, Mozambique, and Rwanda
Growth, Poverty and Inequality Interactions: Some Basics Relationships • High level of economic growth necessary but not sufficient condition for poverty reduction: • Key intermediary in growth-poverty outcome: Growth-Inequality Interaction 1. Growth accompanied by rise in income inequality reduces growthpoverty elasticity. 2. Higher initial level of income inequality reduces growth-poverty elasticity. 3. Income inequality-growth eleasticties are inertial over time Ravallion and Chen (1997); Kanbur(2004); Kanbur & Squire (1999).

The small sample size of other developing countries in the low income group makes determining statistical significance difficult.
The average Gini coefficient for Africa is 0.43, which is 1.1 times the coefficient for the rest of the developing world at 0.39 On average, the top 20 percent of earners in Africa have an income that is over 10 times that of the bottom 20 percent

The Nature, Size and Pattern of Inequality in Africa •
When excluding the 7 outlier African economies, we see that the average Gini coefficient for the rest of the continent declines from 0.45 in the early 1990s to a current level of 0.40 (a 9 percent decline).
•
This latter average is almost equal to that of the rest of the developing world

The Nature, Size and Pattern of Inequality in Africa •
Countries such as Egypt, Malawi and Madagascar have witnessed a narrowing of the income distribution over time.
•
Whereas Cote d’Ivoire, South Africa and Uganda have experienced a rise in inequality since the 1990s.
•
South Africa remains the most unequal African country, and indeed one of the most unequal in the world.

The Nature, Size and Pattern of Inequality in Africa: Five Key Results • Africa: Higher mean and median level of inequality when compared with the rest of the developing region. • Presence of ‘African Outliers’: 7 economies exhibiting extremely high levels of inequality. Excluding the African Outliers - Africa’s level of inequality approximates those of other developing economies. • Inequality has on average declined in Africa, driven by economies not highly unequal. • No obvious trend around nature and pattern of African inequality over time • High inequality African economies: Stronger relationship between economic growth and inequality.
Africa’s Growth-Poverty-Inequality Nexus Poverty Rates Across Africa, LAC and South Asia, 2010
• Poverty rates and the depth of poverty is greater in Africa. • Two-thirds of the population in the four African regions, excluding North Africa, living below the $2 a day poverty line, are living in extreme poverty. • DRC,Ethiopia,Nigeria & Tanzania constitute almost 50% of Africa’s poor.

• The estimated growth elasticity of poverty in the two decades since 1990 in SSA is -0.7, which implies that a one percent growth in consumption is estimated to reduce poverty by 0.7 percent. For the rest of the world (excl. China), this elasticity is substantially higher at -2. • The impact of growth on poverty reduction is lower when initial inequality and mineral resource dependence are higher

Inequality and Structural Change in Africa • Gradual shift away from Agriculture - But not toward manufacturing. • Services sector absorbed most of the shift away from Agriculture, becoming the largest share in GDP for many African Economies • Industry in Africa: Dominated by Mining activities. • Considerable decline in manufacturing value added since the 1990s and 2000s across the continent. • Africa’s growth path and pattern of structural change: o One heavily dependent on natural resources o Poor performance of the manufacturing sector (limiting employment creation) o Over-reliance on subsistence farming.
Inequality and Structural Change in Africa 10
Change in Industry and Manufacturing as Shares of GDP, percentage points (2000-2010) • In most African economies – 35 out of 50 – mining and utilities have seen a rising share in GDP. • Fast growing resourcerich economies have some of the largest shifts of economic activity toward these two sectors. • Represenative of Africa’s lack of Structural Change.

Drivers of Inequality in Africa: Microeconomic and Institutional Considerations • High levels of initial inequality in SSA: Related to how natural endowments shaped nature of colonial institutions • Post-independence Inequality: • Small European populations (that still retained wealth) • Small highly extractive administrations • Focus on law & order rather than economic development.
• Independence: Wealth transferred to small group of African elite. • Sub-national tensions (ethnicity, religion and/or race) further determined initial distribution of resources • Continue to determine provision of public goods and access to labour market opportunities.

• While the average levels of inequality are relatively similar between resource-dependent and non-resource-dependent economies – there are a number of resource dependent countries with very high levels of inequality, close to and above 60. • There is a greater risk of high inequality outcomes in resource dependent economies.

Drivers of Inequality in Africa: Drivers of Inequality in Resource-Rich Countries • Number of potential channels through which a natural resource dependent economy may lead to rising inequality: – Political capture of rents – Ineffective and unprogressive tax systems – Overly complicated ownership structures of extractive industry companies; – Industrialisation and human capital upgrading strategies are poorly realised; – States do not fully consider appropriate social welfare programmes.
• Above in turn all inextricably linked to poor governance and lack of transparency in government revenue collection and expenditure allocations.

Gender Inequality Index, Upper Half of the Global Distribution, 2014
Source: The Economist, 2013 using United Nations data http://www.economist.com/blogs/freeexchange/2013/11/gender-inequallity
• Since the late 1990s, there has been some progress in equalizing access to education for girls and boys in SSA - predominantly at the primary school level • There has been no progress on average in achieving gender parity in secondary schooling, whilst there has been a widening of gender inequality in tertiary educational enrolment
Conclusions • On average, Africa has higher than average and median inequality when compared to the rest of the developing regions • Seven ‘African outlier’ economies exhibiting extremely high levels of inequality – serve to drive this inequality differential with the rest of the developing world • Over time, based on available data, average levels of inequality have declined in Africa, driven mostly by the economies not classified as highly unequal • For countries with initially high levels of inequality, there is a stronger relationship between economic growth and inequality –confirmation of the cross-country evidence outside of Africa.
Conclusions Drivers of Inequality in Africa: 1. Dependence on natural resources has deleterious impact on building effective, transparent and accountable institutions. 2. Lack of a dynamic manufacturing sector to absorp new work-seekers and diversify employment opportunities. 3. Labour market structure of many African economies: Large shre of labour force involved in low-income agricultural self-employment or in informal sector jobs - exacerbates existing inequality. 4. Low stock of human capital: Without rapid rise in supply of skilled workers, inequality-inducing skills premia will persist in African labour markets.
