This paper proposes two new indices of relative deprivation, derived from an extension of the concept of generalized Gini to the measurement of distributional change. Population- and income-weighted relative deprivation indices are then defined and, using panel data from the Consortium of...

This paper compares two approaches to the derivation of asset indices in order to derive measures of multidimensional poverty. The first one assumes that there exists an order of acquisition of durable goods and access to services. The second one applies correspondence analysis to the same data...

Income and wealth inequality rose over the first 150 years of US history. They rose in Britain before 1875, especially 1740–1810. The first half of the 20th century equalized pre-fisc incomes both in Britain and in America. From the 1970s to the 1990s inequality rose in both countries,...

This paper examines three possible approaches to pro-poor growth. The first one assumes that the poverty line remains constant in real terms over time. The second perspective examines the case where the poverty line is equal to half the median of the income distribution but assumes that such a...

Inequality, bi-polarization and polarization are related but distinct concepts aiming at analysing the income distribution. This paper first recalls the main differences between these three notions of inequality, bipolarization and polarization and then suggests using the so-called Shapley...

The world economy has become more unequal over the last two centuries. Since within- country inequality exhibits no ubiquitous trend, it follows that virtually all of the observed rise in world income inequality has been driven by widening gaps between nations, while almost none of it has driven...

Is inequality largely the result of the Industrial Revolution? Or, were pre-industrial incomes and life expectancies as unequal as they are today? For want of sufficient data, these questions have not yet been answered. This paper infers inequality for 14 ancient, pre-industrial societies using...

In order to credibly "sell" legitimate children to their spouse, women must forego more attractive mating opportunities. This paper derives the implications of this observation for the pattern of matching in marriage markets, the dynamics of human capital accumulation, and the evolution of the...

This paper examines three possible approaches to pro-poor growth. The first one assumes that the poverty line remains constant in real terms over time. The second perspective examines the case where the poverty line is equal to half the median of the income distribution but assumes that such a...

Thomas Piketty's monumental Capital in the Twenty-First Century has transported us to a higher understanding of historical movements in inequality. This essay ranks the promise of different paths that scholars can usefully follow from the point to which his book has guided us. The main path to...
