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 multiple indicator-multiple cause (MIMIC) method is a well-established tool for measuring informal economic activity. However, it has been criticized because GDP is used both as a cause and indicator variable. To address this issue, this paper applies for the first time the light intensity approach (instead of GDP). It also uses the Predictive Mean Matching (PMM) method to estimate the size of the informal economy for Sub-Saharan African countries over 24 years. Results suggest that informal economy in Sub-Saharan Africa remains among the largest in the world, although this share has been very gradually declining. It also finds significant heterogeneity, with informality ranging from a low of 20 to 25 percent in Mauritius, South Africa and Namibia to a high of 50 to 65 percent in Benin, Tanzania and Nigeria.

Africa is the world’s poorest continent, but amid all the bad news, there is hope for change. This pamphlet examines the lessons to be learned from some of the more successful economies south of the Sahara, and discusses a policy framework to promote sustainable economic growth and reduce poverty across the region.

The Middle East and North Africa (MENA) is an economically diverse region. Despite undertaking economic reforms in many countries, and having considerable success in avoiding crises and achieving macroeconomic stability, the region’s economic performance in the past 30 years has been below potential. This paper takes stock of the region’s relatively weak performance, explores the reasons for this out come, and proposes an agenda for urgent reforms.
