When income is redistributed at national level, the minimum requirement is that the transfers should be progressive, that is flow from richer to poorer individuals. The same rule should hold at the global level: it is not sufficient that transfers be from a richer to a poorer country. But...

Inequality in world income is very high, according to household surveys, more because of differences between mean country incomes than because of inequality within countries. World inequality increased between 1988 and 1993, driven by slower growth in rural per capita incomes in populous Asian...

Suppose that all people in the world are allocated only two characteristics: country where they live and social class within that country. Assume further that there is no migration. We show that 90 percent of variability in people's global income position (percentile in world income...

The paper discusses recent world income inequality calculations by Sala-i-Martin. It shows that the two main problems with which the author had to grapple (too few data to derive countries' income distributions, and sparseness of such data in time) are not solved in a satisfactory fashion. They,...

Some economists have argued that the process of disintegration of world economy between the two World Wars has led to increased income divergence between the countries. This is in keeping with the view that economic integration leads to income convergence, and consequently that income divergence...

Using social tables, we make an estimate of global inequality (inequality among world citizens) in early 19th century. We then show that the level and composition of global inequality have changed over the last two centuries. The level has increased reaching a high plateau around 1950s, and the...

The effect of the distribution of political rights on income inequality has been studied both theoretically and empirically. This paper reviews the existing literature and, in particular, the available empirical evidence. Our reading of the literature suggests that formal exclusion from the...

New data derived directly from household surveys are used to examine the effects of globalization on income distribution in poor and rich countries. The article looks at the impact of openness and of direct foreign investment on relative income shares across the entire income distribution. It...

Suppose that all people in the world are allocated only two characteristics over which they have (almost) no control: country of residence and income distribution within that country. Assume further that there is no migration. We show that more than one-half of variability in income of world...

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...
