Working Paper
pdf
The interest in the level of global inequality has surged in recent years. This paper complements existing estimates of global inequality by providing the first estimates of the level of bipolarization of the global income distribution. During 1975–2010, global bipolarization declined substantially...

– Causes and consequences
This paper re-examines the determinants and consequences of redistribution in light of improved data and methods relative to earlier literature. In particular, we use the latest version of the UNU-WIDER’s Income Inequality Database to have the best available estimates of both pre- and post...

– How large is the effect of top incomes?
In this paper, we estimate the recent evolution of global interpersonal inequality and examine the effect of omitted top incomes on the level and direction of global inequality. We propose a methodology to estimate the truncation point of household surveys by combining information on income shares...

Ethiopia has experienced rapid economic growth since 2005. Real gross domestic product (GDP) grew at an average rate of 10.5 per cent per annum for the period between 2004–05 and 2013–14. Public investment in key infrastructure and interventions in the agriculture sector have made important...

This paper looks to uncover the growth traps and opportunities for the South African economy, with a focus on underlying labour market dynamics. We explore the potential of South Africa’s demographic dividend. We also consider the structure of the labour market and the growth-employment interactions...

Ghana’s status as one of the African Lions is linked to the country’s remarkable growth performance, which culminated in the attainment of lower middle-income status. However, employment response to growth has been weak. Additionally, growth has been accompanied by substantial reduction in poverty...

This paper mainly analyses the drivers of economic growth in Kenya and the linkages to the labour market dynamics, with a focus on population growth, its structure, and the prospects of reaping a demographic dividend. This is in recognition that Kenya, as the ninth largest economy in Africa and the...

This study examines the relationship between growth and employment in Nigeria to gain insights into the country's paradox of high economic growth alongside rising poverty and inequality. The methodology adopted is the Shapley decomposition approach, complemented with econometric estimation of the...

Over the past twenty years, Mozambique has achieved remarkable progress in promoting macroeconomic growth and stability. Nonetheless, poverty rates remain high and labour market activity is dominated by smallholder farming. We use recent household survey data to dig into these trends and provide an...

The financial intermediation-growth nexus is a widely studied topic in the literature of development economics. Deepening financial intermediation may promote economic growth by mobilizing more investments, and lifting returns to financial resources, which raises productivity. Relying on provincial...

– A Regression-based Decomposition Approach
This paper proposes a decomposition framework for quantifying contributions of the determinants of poverty to spatial differences or temporal changes in poverty. This framework is then applied to address the issue why poverty incidence is higher in inland than in coastal China. The empirical...

– Trends, Causes and Policy Implications
This paper depicts the trend of regional inequality in rural China for the period 1985-2002. The total inequality is decomposed into the so-called within- and between-components when China is divided into three regional belts (east, central and west). A regression-based accounting framework is then...

– A Decomposition Framework with Application to China
This paper proposes a framework for incorporating longitudinal distributional changes into poverty decomposition. It is shown that changes in the Sen-Shorrocks-Thon index over time can be decomposed into two components—one component reflects the progressivity of income growth among the original poor...

Relying on a recently developed decomposition framework, this paper explores spatial distribution of innovation capability in China. It is found that at the regional level, China's inequality in innovation capability increased from 1995 to 2004. At the provincial level, the inequality decreased from...

– Trends and Causes
Applying the Shapley decomposition to unit-record household survey data, this paper investigates the trends and causes of poverty in China in the 1990s. The changes in poverty trends are attributed to two proximate causes; income growth and shifts in relative income distribution. The Foster-Greer...
Working Paper

This paper describes and decomposes wage differences between female and male workers. The results indicate that females receive low wages because of unequal pay within sectors, and that the wage gap caused by the difference in sectoral attainment is small. The results also reveal that a lion’s share...
