Natural resource revenues are an increasingly important financing source for public investment in many developing economies. Investing volatile resource revenues, however, may subject an economy to macroeconomic instability. This paper applies to Angola the fiscal framework developed in Berg et al. (forthcoming) that incorporates investment inefficiency and absorptive capacity constraints, often encountered in developing countries. The sustainable investing approach, which combines a stable fiscal regime with external savings, can convert resource wealth to development gains while maintaining economic stability. Stochastic simulations demonstrate how the framework can be used to inform allocations between capital spending and external savings when facing uncertain oil revenues. An overly aggressive investment scaling-up path could result in insufficient fiscal buffers when faced with negative oil price shocks. Consequently, investment progress can be interrupted, driving up the capital depreciation rate, undermining economic stability, and lowering the growth benefits of public investment.

For a long time, economic research on Africa was not seen as a profitable venture intellectually or professionally-few researchers in top-ranked institutions around the world chose to become experts in the field. This was understandable: the reputation of Africa-centered economic research was not enhanced by the well-known limitations of economic data across the continent. Moreover, development economics itself was not always fashionable, and the broader discipline of economics has had its ups and downs, and has been undergoing a major identity crisis because it failed to predict the Great Recession. Times have changed: many leading researchers-including a few Nobel laureates-have taken the subject of Africa and economics seriously enough to devote their expertise and creativity to it. They have been amply rewarded: the richness, complexities, and subtleties of African societies, civilizations, rationalities, and ways of living, have helped renew the humanities and the social sciences-and economics in particular-to the point that the continent has become the next major intellectual frontier to researchers from around the world. In collecting some of the most authoritative statements about the science of economics and its concepts in the African context, this ^lhandbook (the first of two volumes) opens up the diverse acuity of commentary on exciting topics, and in the process challenges and stimulates the quest for knowledge. Wide-ranging in its scope, themes, language, and approaches, this volume explores, examines, and assesses economic thinking on Africa, and Africa's contribution to the discipline. The editors bring a set of powerful resources to this endeavor, most notably a team of internationally-renowned economists whose diverse viewpoints are complemented by the perspectives of philosophers, political scientists, and anthropologists.

This Volume 17 of the African Development Perspectives Yearbook considers the following major issues: the macroeconomic policies in post-conflict countries (especially reviews of growth, social progress, and public finance strategies in medium-term frameworks) with Sudan and South Sudan as the country cases; and macroeconomic policy formation in West Africa -- with case studies presented on Senegal and Nigeria in the West African Monetary Zone and the CFA Zone. In addition, the book presents book reviews and book notes. (Series: African Development Perspectives Yearbook - Vol. 17) [Subject: African Studies, Economics]

Selected Issues

Natural resource revenues provide a valuable source to finance public investment in developing countries, which frequently face borrowing constraints and tax revenue mobilization problems. This paper develops a dynamic stochastic small open economy model to analyze the macroeconomic effects of investing natural resource revenues, making explicit the role of pervasive features in these countries including public investment inefficiency, absorptive capacity constraints, Dutch disease, and financing needs to sustain capital. Revenue exhaustibility raises medium-term issues of how to sustain capital built during a windfall, while revenue volatility raises short-term concerns about macroeconomic instability. Using the model, country applications show how combining public investment with a resource fund---a sustainable investing approach---can help address the macroeconomic problems associated with both exhaustibility and volatility. The applications also demonstrate how the model can be used to determine the appropriate magnitude of the investment scaling-up (accounting for the financing needs to sustain capital) and the adequate size of a stabilization fund (buffer).

Growth in sub-Saharan Africa has weakened after more than a decade of solid growth, although this overall outlook masks considerable variation across the region. Some countries have been negatively affected by falling prices of their main commodity exports. Oil-exporting countries, including Nigeria and Angola, have been hit hard by falling revenues and the resulting fiscal adjustments, while middle-income countries such as Ghana, South Africa, and Zambia are also facing unfavorable conditions. This October 2015 report discusses the fiscal and monetary policy adjustments necessary for these countries to adapt to the new environment. Chapter 2 looks at competitiveness in the region, analyzing the substantial trade integration that accompanied the recent period of high growth, and policy actions to nurture new sources of growth. Chapter 3 looks at the implications for the region of persistently high income and gender inequality and ways to reduce them.

Growth in sub-Saharan Africa has recovered relative to 2016, but the momentum is weak and per capita incomes are expected to barely increase. Further, vulnerabilities have risen in many countries, adding to the urgency of implementing the fiscal consolidations planned in most countries and with stepped up efforts to strengthen growth.

Growth momentum in sub-Saharan Africa remains fragile, marking a break from the rapid expansion witnessed since the turn of the millennium. 2016 was a difficult year for many countries, with regional growth dipping to 1.4 percent—the lowest level of growth in more than two decades. Most oil exporters were in recession, and conditions in other resource-intensive countries remained difficult. Other nonresource-intensive countries however, continued to grow robustly. A modest recovery in growth of about 2.6 percent is expected in 2017, but this falls short of past trends and is too low to put sub-Saharan Africa back on a path of rising living standards. While sub-Saharan Africa remains a region with tremendous growth potential, the deterioration in the overall outlook partly reflects insufficient policy adjustment. In that context, and to reap this potential, strong and sound domestic policy measures are needed to restart the growth engine.

Growth in much of Sub-Saharan Africa is expected to remain strong, driven by efforts to invest in infrastructure and strong agricultural production. The current Ebola outbreak in Guinea, Liberia, and Sierra Leone is exacting a heavy toll, with spillovers to neighboring countries. External threats to the region's overall positive outlook include global financial conditions and a slowdown in emerging market growth.

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.
