Publication The Devil is in the Detail: Growth, Inequality and Poverty Reduction in Africa in the Last Two Decades(Oxford University Press, 2019-08) Clementi, Fabio; Fabiani, Michele; Molini, VascoThe 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.Publication Agriculture, Aid, and Economic Growth in Africa(Published by Oxford University Press on behalf of the World Bank, 2019-02) McArthur, John W.; Sachs, Jeffrey D.How can foreign aid to agriculture support economic growth in Africa? This paper constructs a geographically indexed applied general equilibrium model that considers pathways through which aid might affect growth and structural transformation of labor markets in the context of soil nutrient variation, minimum subsistence consumption requirements, domestic transport costs, labor mobility, and constraints to self-financing of agricultural inputs. Using plausible parameters, the model is presented for Uganda as an illustrative case. We present three stylized scenarios to demonstrate the potential economy-wide impacts of both soil nutrient loss and replenishment, and how foreign aid can be targeted to support agricultural inputs that boost rural productivity and shift labor to boost real wages. One simulation shows how a temporary program of targeted official development assistance (ODA) for agriculture could generate, contrary to traditional Dutch disease concerns, an expansion in the primary tradable sector and positive permanent productivity and welfare effects, leading to a steady decline in the need for complementary ODA for budget support.Publication No Condition Is Permanent: Middle Class in Nigeria in the Last Decade(Taylor and Francis, 2017-09-21) Corral Rodas, Paul Andres; Molini, VascoThe 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.Publication Explaining Ethiopia’s Growth Acceleration—The Role of Infrastructure and Macroeconomic Policy(Elsevier, 2017-08) Moller, Lars Christian; Wacker, Konstantin M.Ethiopia has experienced an impressive growth acceleration over the past decade. This was achieved on the back of an economic strategy emphasizing public infrastructure investment supported by heterodox macro-financial policies. This paper identifies the drivers of Ethiopia’s recent growth episode and examines the extent to which they were typical or unique. It combines country-specific information with the results of a cross-country panel regression model. We find that Ethiopia’s growth is explained well by factors correlating with growth in a broad range of countries in recent decades, including public infrastructure investment, restrained government consumption, and a conducive external environment. On the other hand, we argue that the policy mix that supported very high levels of public investment in Ethiopia was, to some extent, unique. Interestingly, macroeconomic imbalances due to this heterodox policy mix only moderately held back growth which helps explain why Ethiopia was able to grow so fast in spite of their presence: their negative effects were quantitatively much less important than the positive growth drivers they helped to achieve. The results suggest that “getting infrastructure right” may outweigh moderate shortcoming in the macro framework at early stages of development. We further relate this country-specific finding to the recent growth literature.Publication The Changing Structure of Africa’s Economies(Published by Oxford University Press on behalf of the World Bank, 2017-06-01) Diao, Xinshen; Harttgen, Kenneth; McMillan, MargaretUsing data from the Groningen Growth and Development Center’s Africa Sector Database and the Demographic and Health Surveys, we show that much of Africa’s recent growth and poverty reduction has been associated with a substantive decline in the share of the labor force engaged in agriculture. This decline is most pronounced for rural females over the age of 25 who have a primary education; it has been accompanied by a systematic increase in the productivity of the labor force, as it has moved from low productivity agriculture to higher productivity services and manufacturing. We also show that, although the employment share in manufacturing is not expanding rapidly, in most of the low-income African countries the employment share in manufacturing has not peaked and is still expanding, albeit from very low levels. More work is needed to understand the implications of these shifts in employment shares for future growth and development in Africa south of the Sahara.Publication 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) Bell, Clive; Devarajan, Shantayanan; Gersbach, HansPrimarily 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).Publication Macro and Micro Perspectives of Growth and Poverty in Africa(Washington, DC: World Bank, 2003-09) Paternostro, Stefano; Christiaensen, Luc; Demery, LionelThis article reviews trends in poverty, economic policies, and growth in a sample of African countries during the 1990s, drawing on the better household data now available. Experiences have varied. Some countries have seen sharp drops in income poverty, whereas others have witnessed marked increases. In some countries overall economic growth has been pro-poor and in others not. But the aggregate numbers hide systematic distributional effects. Taking both macro and micro perspectives of growth and poverty in Africa, the article draws four key conclusions. First, economic policy reforms (improving macroeconomic balances and liberalizing markets) appear conducive to reducing poverty. Second, market connectedness is crucial to enable participation in the gains from economic growth. Some regions and households by virtue of their remoteness were left behind when growth picked up. Third, education and access to land emerge as key private endowments to help households benefit from new economic opportunities. Finally, rainfall variations and ill health have profound effects on poverty outcomes, underscoring the significance of social risk management in poverty reduction strategies in Africa.Publication How Research Can Assist Policy : The Case of Economic Reforms in Uganda(World Bank, 2002-09-01) Mackinnon, John; Reinikka, RitvaResearch has had a powerful impact on policy in Uganda, affecting the climate of opinion, improving the quality of the policy debate, and helping focus public policy and intervention on poverty reduction. Uganda s successful use of knowledge and research to help set public policy priorities demonstrates that even a poor post conflict country can, in a relatively short period of time, create an effective information base and feedback mechanisms for decision making.
