1 Growth, Inequality and Poverty Reduction in Africa Francisco H. G. Ferreira The World Bank and IZA

2 OUTLINE I. An African growth profile II. Effects on poverty, mediated by inequality III. Four key policy areas 1. Macroeconomic management under receding tailwinds 2. Investment in human and physical capital 3. Promoting growth in the places and sectors where the poor are 4. and creating social protection and promotion systems that enable them to share in growth elsewhere.

3 Real GDP per capita in US$ at 2005 prices (in logs) AFRICA RISING : TWO DECADES OF SUSTAINED ECONOMIC GROWTH Actual Trend reversing two lost decades from the mid-70s to the mid-90s.

4 Cumulative growth index (1995=1.0) IN MANY WAYS, THIS HAS BEEN HIGH-QUALITY GROWTH Africa s growth has been strongly investment driven, rather than consumptiondriven Growth has also been associated with rapid increases in foreign trade both imports and exports. Consumption Government Spending Imports Investment Exports Note: The figure depicts the median cumulative growth of the different components of aggregate demand for a sample of 44 Sub-Saharan African countries over the period The data on the components of aggregate demand (household consumption, investment, government consumption expenditure, exports and imports) was originally computed in US dollars at 2005 prices.

6 Real GDP per capita growth Real GDP growth BUT THERE ARE IMPORTANT CAVEATS: 1. Per capita growth is less impressive due to rapid population growth GDP growth in SSA, China and other developing countries 15% 13% 11% 9% 7% 5% 3% 1% -1% Rest of Developing (excl. China) China Sub-Saharan Africa GDP growth per capita in SSA, China and other developing countries 15% 13% 11% 9% 7% 5% 3% 1% -1% Rest of Developing (excl.

7 Cumulative growth index (1995=1.0) 2. Growth performance varies significantly across countries Fragile and conflictaffected states grow markedly more slowly than non-fragile countries. There are also substantial differences between resource-rich and nonresource-rich countries SSA Resource rich Non-resource rich Fragile Non-fragile PER CAPITA GROWTH RATES : Fragile: 1.2% Non-fragile: 2.3% Non resource-rich: 1.7% Resource-rich: 2.6% Note: The Index presented in this figure depicts the cumulative growth in real per capita GDP from 1995 to 2012 across 44 Sub-Saharan Africa. Resource rich countries (9 oil and 12 non-oil) are those with average rents from natural resources (excluding forests) that exceed 5% of GDP in Fragile countries (16) are defined as having either a harmonized CPIA rating of 3.2 or less, or presence of UN and/or regional peacekeeping or peacebuilding missions during the past 3 years.

9 Cumulative growth index (1995=1.0) 3. Growth performance also varies significantly across sectors, within countries Agriculture and manufacturing account for a declining share of GDP in the region The natural resource sector (which includes mining as well as construction) and the services sector have grown faster than the economy on average, and account for increasing shares. Agriculture Resources Manufacturing Services Note: The resources sector includes construction, mining and quarrying, and gas, electricity and water. Sectoral value added information is in US dollars at 2005 prices from the World Development Indicators.

18 TO SUM UP Poverty in Africa remains high, and the pace of reduction remains slow Sustained economic growth in the next two decades is essential for progress But it is not sufficient: Growth must be more inclusive With falling inequality in outcomes and opportunities.

26 GROWTH THAT TAKES PLACE IN RURAL AREAS WHERE MOST OF THE POOR LIVE IS MOST EFFECTIVE IN REDUCING POVERTY Econometric evidence from China, India and Brazil suggests that the geographic and sector composition of growth affects the overall growth elasticity of poverty. In Africa, most of the growth has not been coming from the places and sectors where the poor are. Contribution of urban and rural areas to population, poverty reduction and consumption growth in Uganda, % 80% 60% Population share Share of poverty reduction Shares in total consumption growth Most of the poverty reduction comes from very specific growth sources 40% 20% 0% -20% Rural Urban Source: Kaminski and Christiaensen 2013

Data from WDI (2014) on sectoral value added as a share of GDP and poverty data PovcalNet (2014) from 1990 to Note: The null hypothesis that the sectoral composition of growth does not matter is rejected at the 1% level for all the poverty measures (Headcount, Poverty Gap and Squared Poverty Gap). This is robust to the inclusion of controls. CROSS-COUNTRY REGRESSIONS SUGGEST THAT GROWTH PATTERNS DO MATTER FOR POVERTY REDUCTION Africa: agriculture and services most poverty reducing Elsewhere: industry and services most poverty reducing VARIABLES Headcount Sub-Saharan Africa Poverty Gap Sq.

29 REDISTRIBUTION CAN BE EFFICIENT AS WELL AS EQUITABLE. THE CCT REVOLUTION IN SOCIAL PROTECTION Since the late 1990s, conditional cash transfers have shown that: (i) Good targeting is possible (ii) Transfers increase family incomes and reduce poverty (iii) Households use the transfers to improve nutrition

31 FAMILIES SYSTEMATICALLY INVEST PART OF WHAT THEY RECEIVE and even to save and invest in physical and financial capital as well! Five years ago when my oldest daughter was in school and we received money from PROGRESA, we saved 600 pesos to buy wood and the other materials for building a chicken coop, and with what was left we bought a few chickens. Since then, we have raised many chickens that we sometimes sell, and we collect 10 to 15 eggs per week that we eat ourselves. - Oportunidades beneficiary in rural Mexico, August 2004, cited in Gertler, Martinez and Rubio-Codina (AEJ: Applied Economics, 2012)

32 FAMILIES SYSTEMATICALLY INVEST PART OF WHAT THEY RECEIVE Community Based Conditional Cash Transfers in Tanzania Some Results (endline) % points Indigenous goats Local chickens INVESTMENT IN LIVESTOCK Cigarettes, tobacco, snuff Insurance (car, medical, life) ANNUAL AVERAGE HOUSEHOLD NON-FOOD EXPENDITURE, LCU Shoes CHILDREN'S ASSETS Note: Investment in livestock refers to additional goats and chickens purchased by treatment households. Additional annual average non-food expenditure by treatment households measured in Tanzanian Shilling (TSH). Children s assets refers to the higher likelihood of treated children to own shoes in percentage points. Source: charts based on results from Evans, Hausladen, Kosec and Reese (2013)

33 CONCLUSIONS Sustained economic growth is essential to the fight against poverty in Africa Macroeconomic prudence reduces vulnerability to receding tailwinds Investment in human and physical capital must become more effective (quality as well as quantity) But growth is not sufficient: shared prosperity will require a reduction in inequality (of outcomes and opportunities) Boost productivity in agricultural and rural off-farm jobs Cash transfers are a real policy option
