A key aspect defining the contemporary income distribution is the (increasing) share the top holds compared to the rest. This paper shows that income concentration increases towards the very top of the distribution, while the shares the middle- and upper-middle-income groups hold remain stable...

This paper adds to our understanding of the causes of income inequality across nations by examining the influence of different aspects of gender equality or female empowerment. Whereas the economics of income inequality has been an area of active academic inquiry, the role of gender equality has...

This paper focuses on the importance data issues to the analysis of growth, poverty and economic inequality. We introduce a number of major databases frequently used in applied research on growth, poverty and global and international inequality. A discussion of data quality, data consistency,...

This paper focuses on an important aspect of economic inequality -- the question of how people perceive inequality and whether these perceptions deviate in any meaningful way from statistical measures of inequality. Perceptions of inequality have been shown to affect happiness, job satisfaction,...

Like the other chapters in this volume of the Handbook of Income Distribution (and its predecessor), the aim of this chapter is to provide a comprehensive review of a particular area of research. We examine the literature on post-1970 trends in poverty and income inequality, up to 2010 or 2011...

In this paper we compute inequality measures over the distribution of a subjective well-being variable constructed from a life satisfaction question included in the Gallup World Poll in almost all countries in the world. We argue that inequality in subjective well-being may be a better proxy for...

This paper presents the global income distribution between all individuals living in the developed world. Global inequality for the group of high-income countries, as measured by the Gini coefficient, stands at 37 in 2013 and has increased by almost 3 Gini points since the mid-1990s. This was...

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...
