Aphorisms that “rising tides raise all boats” or that material advances of the rich eventually “trickle down” to the poor are really maxims regarding the nature of stochastic processes that underlay the income/wellbeing paths of groups of individuals. This paper looks at the implications...

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,...

The notion of Equality of Opportunity (EO) has pervaded much of economic and social justice policy over the last half century in conveying a sense of liberation from the circumstances that constrain an individual’s ability to achieve it, and it has been a cornerstone of many gender equality...

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...

The most popular general univariate polarization indexes for discrete and continuous variables are extended and combined to describe the extent of polarization between agents in a distribution defined over a collection of many discrete and continuous agent characteristics. A formula for the...

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...

The aim of this chapter is to highlight some key aspects of recent economic research on the welfare state and antipoverty policy in rich countries and to explore their implications. We begin with the conceptualization and measurement of poverty before sketching out some core features and...
