The paper investigates empirically the determinants of economic growth for a large sample of sub-Saharan African countries during 1981-92. The results indicate that (i) an increase in private investment has a relatively large positive impact on per capita growth; (ii) growth is stimulated by public policies that lower the budget deficit in relation to GDP (without reducing government investment), reduce the rate of inflation, maintain external competitiveness, promote structural reforms, encourage human capital development, and slow population growth; and (iii) convergence of per capita income occurs after controlling for human capital development and public policies.

Sustainable infrastructure development is vital for Africa s prosperity. And now is the time to begin the transformation. This volume is the culmination of an unprecedented effort to document, analyze, and interpret the full extent of the challenge in developing Sub-Saharan Africa s infrastructure sectors. As a result, it represents the most comprehensive reference currently available on infrastructure in the region. The book covers the five main economic infrastructure sectors information and communication technology, irrigation, power, transport, and water and sanitation. 'Africa s Infrastructure: A Time for Transformation' reflects the collaboration of a wide array of African regional institutions and development partners under the auspices of the Infrastructure Consortium for Africa. It presents the findings of the Africa Infrastructure Country Diagnostic (AICD), a project launched following a commitment in 2005 by the international community (after the G8 summit at Gleneagles, Scotland) to scale up financial support for infrastructure development in Africa. The lack of reliable information in this area made it difficult to evaluate the success of past interventions, prioritize current allocations, and provide benchmarks for measuring future progress, hence the need for the AICD. Africa s infrastructure sectors lag well behind those of the rest of the world, and the gap is widening. Some of the main policy-relevant findings highlighted in the book include the following: infrastructure in the region is exceptionally expensive, with tariffs being many times higher than those found elsewhere. Inadequate and expensive infrastructure is retarding growth by 2 percentage points each year. Solving the problem will cost over US$90 billion per year, which is more than twice what is being spent in Africa today. However, money alone is not the answer. Prudent policies, wise management, and sound maintenance can improve efficiency, thereby stretching the infrastructure dollar. There is the potential to recover an additional US$17 billion a year from within the existing infrastructure resource envelope simply by improving efficiency. For example, improved revenue collection and utility management could generate US$3.3 billion per year. Regional power trade could reduce annual costs by US$2 billion. And deregulating the trucking industry could reduce freight costs by one-half. So, raising more funds without also tackling inefficiencies would be like pouring water into a leaking bucket. Finally, the power sector and fragile states represent particular challenges. Even if every efficiency in every infrastructure sector could be captured, a substantial funding gap of $31 billion a year would remain. Nevertheless, the African people and economies cannot wait any longer. Now is the time to begin the transformation to sustainable development.

The World Bank Group has two overarching goals: End extreme poverty by 2030 and promote shared prosperity by boosting the incomes of the bottom 40 percent of the population in each economy. As this year’s Poverty and Shared Prosperity report documents, the world continues to make progress toward these goals. In 2015, approximately one-tenth of the world’s population lived in extreme poverty, and the incomes of the bottom 40 percent rose in 77 percent of economies studied. But success cannot be taken for granted. Poverty remains high in Sub- Saharan Africa, as well as in fragile and conflict-affected states. At the same time, most of the world’s poor now live in middle-income countries, which tend to have higher national poverty lines. This year’s report tracks poverty comparisons at two higher poverty thresholds—$3.20 and $5.50 per day—which are typical of standards in lower- and upper-middle-income countries. In addition, the report introduces a societal poverty line based on each economy’s median income or consumption. Poverty and Shared Prosperity 2018: Piecing Together the Poverty Puzzle also recognizes that poverty is not only about income and consumption—and it introduces a multidimensional poverty measure that adds other factors, such as access to education, electricity, drinking water, and sanitation. It also explores how inequality within households could affect the global profile of the poor. All these additional pieces enrich our understanding of the poverty puzzle, bringing us closer to solving it. For more information, please visit worldbank.org/PSP

Access to modern energy is central in addressing the major global challenges of the 21st century, including poverty, climate change and famine. However large parts of the world, especially in Sub-Saharan Africa (SSA) have poor or no access to modern energy. Victoria Nalule argues that SSA countries have many common energy challenges which could be tackled with collective efforts through regional cooperation. By means of a legal and comparative analysis and a seven-step framework, the book explores the current regional mechanisms employed in Africa to address the challenge of energy poverty and access and whether they are effective in tackling the challenge of energy access, including regional energy infrastructure and regional energy regulations. Chapters discuss the evolution of regionalism in SSA and the role of regional cooperation in the development of renewable energy as a means of confronting both energy access and climate change. Specifically the nexus between energy access, renewable energy and climate change is covered as well as the potential of fossil fuels in addressing energy poverty. The establishment and development of regional energy infrastructure as one of the mechanisms of addressing energy access challenges in SSA and regional efforts to harmonise energy regulation are explored. Finally a concluding chapter provides recommendations for policy makers and other relevant stakeholders on how best to implement some of the suggestions made in previous chapters. International organisations, regional organisations, government officials, scholars and students with interest in the energy sector will highly benefit from this book.

For African cities to grow economically as they have grown in size, they must create productive environments to attract investments, increase economic efficiency, and create livable environments that prevent urban costs from rising with increased population densification. What are the central obstacles that prevent African cities and towns from becoming sustainable engines of economic growth and prosperity? Among the most critical factors that limit the growth and livability of urban areas are land markets, investments in public infrastructure and assets, and the institutions to enable both. To unleash the potential of African cities and towns for delivering services and employment in a livable and environmentally friendly environment, a sequenced approach is needed to reform institutions and policies and to target infrastructure investments. This book lays out three foundations that need fixing to guide cities and towns throughout Sub-Saharan Africa on their way to productivity and livability.

Infrastructure and Poverty in Sub-Saharan Africa analyzes the extent to which, how, and how fast the infrastructure needs of the poor have been met in Sub-Saharan Africa. Estache and Wodon explore the extent to which some key policies have hurt or helped progress in trying to speed the expansions of coverage so clearly needed in the region. They focus on electricity, water, sanitation, and other services at the core of the day-to-day needs of the population, examining the extent to which reforms of the last 15-20 years have managed to reduce the infrastructure gap. They anchor their analysis on the evidence available about the macroeconomic importance of infrastructure for the region, the policies that have been adopted to accelerate coverage, and a detailed assessment of the poverty dimensions of infrastructure.

Cities in Sub-Saharan Africa are experiencing rapid population growth. Yet their economic growth has not kept pace. Why? One factor might be low capital investment, due in part to Africa's relative poverty: Other regions have reached similar stages of urbanization at higher per capita GDP. This study, however, identifies a deeper reason: African cities are closed to the world. Compared with other developing cities, cities in Africa produce few goods and services for trade on regional and international markets To grow economically as they are growing in size, Africa's cities must open their doors to the world. They need to specialize in manufacturing, along with other regionally and globally tradable goods and services. And to attract global investment in tradables production, cities must develop scale economies, which are associated with successful urban economic development in other regions. Such scale economies can arise in Africa, and they will--if city and country leaders make concerted efforts to bring agglomeration effects to urban areas. Today, potential urban investors and entrepreneurs look at Africa and see crowded, disconnected, and costly cities. Such cities inspire low expectations for the scale of urban production and for returns on invested capital. How can these cities become economically dense--not merely crowded? How can they acquire efficient connections? And how can they draw firms and skilled workers with a more affordable, livable urban environment? From a policy standpoint, the answer must be to address the structural problems affecting African cities. Foremost among these problems are institutional and regulatory constraints that misallocate land and labor, fragment physical development, and limit productivity. As long as African cities lack functioning land markets and regulations and early, coordinated infrastructure investments, they will remain local cities: closed to regional and global markets, trapped into producing only locally traded goods and services, and limited in their economic growth.

Sub-Saharan Africa's turnaround over the past couple of decades has been dramatic. After many years in decline, the continent's economy picked up in the mid-1990s. Along with this macroeconomic growth, people became healthier, many more youngsters attended schools, and the rate of extreme poverty declined from 54 percent in 1990 to 41 percent in 2015. Political and social freedoms expanded, and gender equality advanced. Conflict in the region also subsided, although it still claims thousands of civilian lives in some countries and still drives pressing numbers of displaced persons. Despite Africa’s widespread economic and social welfare accomplishments, the region’s challenges remain daunting: Economic growth has slowed in recent years. Poverty rates in many countries are the highest in the world. And notably, the number of poor in Africa is rising because of population growth. From a global perspective, the biggest concentration of poverty has shifted from South Asia to Africa. Accelerating Poverty Reduction in Africa explores critical policy entry points to address the demographic, societal, and political drivers of poverty; improve income-earning opportunities both on and off the farm; and better mobilize resources for the poor. It looks beyond macroeconomic stability and growth—critical yet insufficient components of these objectives—to ask what more could be done and where policy makers should focus their attention to speed up poverty reduction. The pro-poor policy agenda advanced in this volume requires not only economic growth where the poor work and live, but also mitigation of the many risks to which African households are exposed. As such, this report takes a "jobs" lens to its task. It focuses squarely on the productivity and livelihoods of the poor and vulnerable—that is, what it will take to increase their earnings. Finally, it presents a road map for financing the poverty and development agenda.
