Zambia is one African country which has evolved from being a classic example of a colonial economy to become an independent state with a large export enclave. The economy has had to face structural problems that have at one time or another, characterised other African economies. This study therefore throws light upon many aspects of the labour markets elsewhere in Africa. Originally published in 1979, this book analyses 3 stages of development in the Zambian labour force: the first running up to 1930 when the Copperbelt was opened up, was followed by over 30 years of economic and employment growth, leading to the emergence of a wage and skill structure that differentiated strongly between Africans and non-Africans. Finally there is the period since the early 1960s when the racial basis for employment and earnings restrictions have been lifted but where inequalities remain. Each of these stages is examined in detail and complemented by a theoretical discussion of the factors affecting the development of the wage structure and earnings differentials within Zambia. The impact of government policy income distribution is also discussed and illustrated by means of a comparative study of government income policies in Zambia, Tanzania and Kenya.

This paper analyzes the extent of income inequality from a global perspective, its drivers, and what to do about it. The drivers of inequality vary widely amongst countries, with some common drivers being the skill premium associated with technical change and globalization, weakening protection for labor, and lack of financial inclusion in developing countries. We find that increasing the income share of the poor and the middle class actually increases growth while a rising income share of the top 20 percent results in lower growth—that is, when the rich get richer, benefits do not trickle down. This suggests that policies need to be country specific but should focus on raising the income share of the poor, and ensuring there is no hollowing out of the middle class. To tackle inequality, financial inclusion is imperative in emerging and developing countries while in advanced economies, policies should focus on raising human capital and skills and making tax systems more progressive.

This state-of-the-art volume presents comparative, empirical research on a topic that has long preoccupied scholars, politicians, and everyday citizens: economic inequality. While income and wealth inequality across all populations is the primary focus, the contributions to this book pay special attention to the middle class, a segment often not addressed in inequality literature. Written by leading scholars in the field of economic inequality, all 17 chapters draw on microdata from the databases of LIS, an esteemed cross-national data center based in Luxembourg. Using LIS data to structure a comparative approach, the contributors paint a complex portrait of inequality across affluent countries at the beginning of the 21st century. The volume also trail-blazes new research into inequality in countries newly entering the LIS databases, including Japan, Iceland, India, and South Africa.

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.
