Income inequality is on the rise, and everyone, from President Obama and Pope Francis to Prince Charles and Standard & Poor's, is talking about it. But these conversations about what are arguably the most significant changes in the distribution of incomes and earnings since the 1940s are leading...

The purpose of this paper is two-fold. First, we develop the measurement theory of polarization for the case in which asset distributions can be described using density functions. Second, we provide sample estimators of population polarization indices that can be used to compare polarization...

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...

This paper investigates the effect of firm-level investment on the levels of income inequality and poverty. Using a sample of firms from 87 countries for the period from 1979 to 2018, we document that firm-level investment is negatively associated with various measures of income inequality. This...

The evaluation of development processes and of public policies often involves comparisons of social states that differ in income distributions, population sizes and life longevity. This may require social evaluation principles to be sensitive to the quality, the quantity and the duration of...

We assess whether global social welfare has improved in the last decades despite (or because of) the substantial increase in global population. We use for this purpose a relatively unknown but simple and attractive social evaluation approach called critical-level generalized utilitarianism...

The deterioration of income inequality is frequently to be found among the suggested negative side-effects of globalization – ‘the rich get richer, and the poor get poorer'. How relevant is this perception? In my opinion, the question can be properly answered only after:1) a careful overview...

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...

In many countries extreme poverty is unnecessary. Yet it persists. We propose a simple index, denoted the Miser index, to measure the extent to which societies have poverty in the midst of affluence. It builds on the generalized Lorenz curve, but can also be seen as a measure of polarization...
