Sub-Saharan Africa has been hit hard by the global recession, but signs of resilience remain. While South Africa and some other middle-income countries were caught in the turbulence of international financial markets, and oil exporters saw government revenues plunge, some countries with wider commodity bases have so far escaped the worst of the crisis. Also, and reassuringly, with stronger initial fiscal and external positions than in past downturns, most countries in the region have been able to partially absorb external shocks by allowing fiscal deficits to rise and reducing interest rates. Exchange rates have generally been allowed to adjust. With many families affected by the crisis, however, progress toward the Millennium Development Goals has receded. Looking ahead, fiscal policy must balance support for the recovery with enhancing future growth prospects, debt sustainability, and poverty reduction. Published biannually in May and October.

This edition of the World Economic Outlook explores how a dramatic escalation of the financial crisis in September 2008 provoked an unprecedented contraction of activity and trade, despite active policy responses. It presents economic projections for 2009 and 2010, and also looks beyond the current crisis, considering factors that will shape the landscape of the global economy over the medium term, as businesses and households seek to repair the damage. The analysis also outlines the difficult policy challenges presented by the overwhelming imperative to take all steps necessary to restore financial stability and revive the global economy, and the longer-run need for national actions to be mutually supporting. The first of two analytical chapters, "What Kind of Economic Recovery?" explores the shape of the eventual recovery. The second, "The Transmission of Financial Stress from Advanced to Emerging and Developing Economies," focuses on the role of external financial linkages and financial stress in transmitting economic shocks.

Global growth is in low gear, and the drivers of activity are changing. These dynamics raise new policy challenges. Advanced economies are growing again but must continue financial sector repair, pursue fiscal consolidation, and spur job growth. Emerging market economies face the dual challenges of slowing growth and tighter global financial conditions. This issue of the World Economic Outlook examines the potential spillovers from these transitions and the appropriate policy responses. Chapter 3 explores how output comovements are influenced by policy and financial shocks, growth surprises, and other linkages. Chapter 4 assesses why certain emerging market economies were able to avoid the classical boom-and-bust cycle in the face of volatile capital flows during the global financial crisis.

The world economy is experiencing a very strong but uneven recovery, with many emerging market and developing economies facing obstacles to vaccination. The global outlook remains uncertain, with major risks around the path of the pandemic and the possibility of financial stress amid large debt loads. Policy makers face a difficult balancing act as they seek to nurture the recovery while safeguarding price stability and fiscal sustainability. A comprehensive set of policies will be required to promote a strong recovery that mitigates inequality and enhances environmental sustainability, ultimately putting economies on a path of green, resilient, and inclusive development. Prominent among the necessary policies are efforts to lower trade costs so that trade can once again become a robust engine of growth. This year marks the 30th anniversary of the Global Economic Prospects. The Global Economic Prospects is a World Bank Group Flagship Report that examines global economic developments and prospects, with a special focus on emerging market and developing economies, on a semiannual basis (in January and June). Each edition includes analytical pieces on topical policy challenges faced by these economies.

This first, annual issue of Regional Economic Outlook: Sub-Saharan Africa analyzes economic, trade, and institutional issues in 2004, and prospects in 2005, for the 42 countries covered by the IMF African Department (for data reasons, Eritrea and Liberia are excluded). Topics examined include responses to exogenous shocks, growth performance and growth-enhancing policies, and the effectiveness of regional trade arrangements. Detailed aggregate and country data (as of February 24, 2005) are provided in the appendix.

The October 2010 Regional Economic Outlook features: (i) an overview of economic developments and prospects in sub-Saharan Africa; (ii) an analytical assessment of how monetary policy changes are transmitted through the region's economies; and (iii) a study of why growth rates in the West African Economic and Monetary Union (WAEMU) have lagged behind other parts of sub-Saharan Africa. The overview highlights the broad-based economic recovery that is now under way in sub-Saharan Africa and projects growth of 5 percent in 2010 and 51⁄2 percent in 2011. It explores the resilience of most economies in the region to the global financial crises of 2007-09 and explains why sound economic policy implementation and a growing orientation of trade toward Emerging Asia are expected to continue to underpin growth. The second chapter provides evidence suggesting that monetary policy may have more power to influence monetary conditions than previously assumed. Main messages from the WAEMU study are the importance of strong policy environments and political stability for achieving sustained growth; and of robust fiscal frameworks for directing resources towards priority spending needs.

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.

The sharp decline in oil and other commodity prices have adversely impacted sub-Saharan Africa. Nevertheless, the region is projected to register another year of solid economic performance. In South Africa, however, growth is expected to remain lackluster, while in Guinea, Liberia, and Sierra Leone the Ebola outbreak continues to exact a heavy economic and social toll. This report also considers how sub-Saharan Africa can harness the demographic dividend from an unprecedented increase in the working age population, as well as the strength of the region's integration into global value chains.

The September 2011 edition of the World Economic Outlook assesses the prospects for the global economy, which is now in a dangerous new phase. Global activity has weakened and become more uneven, confidence has fallen sharply recently, and downside risks are growing. Against a backdrop of unresolved structural fragilities, a barrage of shocks hit the international economy this year, including the devastating Japanese earthquake and tsunami, unrest in some oil-producing countries, and the major financial turbulence in the euro area. Two of the forces now shaping the global economy are high and rising commodity prices and the need for many economies to address large budget deficits. Chapter 3 examines the inflationary effects of commodity price movements and the appropriate monetary policy response. Chapter 4 explores the implications of efforts by advanced economies to restore fiscal sustainability and by emerging and developing economies to tighten fiscal policy to rebuild fiscal policy room and in some cases to restrain overheating pressures.

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.
