Limited diversification is an underlying characteristic of many low-income countries (LICs). Concentration in sectors with limited scope for increases in productivity and quality may result in less broad-based and sustainable growth. Moreover, lack of diversification may increase exposure to adverse external shocks and macroeconomic instability. The SDN will have three objectives. First, to review and extend the evidence, from the existing literature and ongoing IMF work, that points to diversification as a crucial aspect of the development process. A major focus will be on cross-country and cross-regional differences in the pace of diversification. Second, to draw lessons from the experiences of those countries that have successfully diversified their economies. Third, to analyze the relationship between diversification, growth, and volatility.

The paper considers concepts of economic diversification with respect to exports (including service sectors) for small states. We assessed the economic performance of different groups of 34 small states over the period of 1990-2015 and found those more diversified experienced lower output volatility and higher average growth than most other small states. Our findings are consistent with conventional economic theories but we found that export diversification has a more significant impact on reducing output volatility than improving long run growth in small states. Diversification requires fundamental changes and should be contemplated in the context of a cohesive development strategy.

Export structure is less diversified in low-income countries (LICs) and especially small states that face resource constraints and small economic size. This paper explores the potential linkages between export structure and economic growth and its volatility in LICs and small states, using a range of indices of export concentration differing in the coverage of industries. The empirical analysis finds that export diversification may promote economic growth and reduce economic volatility in these countries. Furthermore, the analysis demonstrates that the economic benefits of export diversification differ by country size and income level—there are bigger benefits for relatively larger and poorer countries within the group of LICs and small states.

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 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 five Regional Economic Outlooks published biannually by the IMF cover Asia and Pacific, Europe, the Middle East and Central Asia, Sub-Saharan Africa, and the Western Hemisphere. In each volume, recent economic developments and prospects for the region are discussed as a whole, as well as for specific countries. The reports include key data for countries in the region. Each report focuses on policy developments that have affected economic performance in the region, and discusses key challenges faced by policymakers. The near-term outlook, key risks, and their related policy challenges are analyzed throughout the reports, and current issues are explored, such as when and how to withdraw public interventions in financial systems globally while maintaining a still-fragile economic recovery.These indispensable surveys are the product of comprehensive intradepartmental reviews of economic developments that draw primarily on information the IMF staff gathers through consultation with member countries.
