Most methods for the analysis of distributional change rely on the changes in the income of a particular group of people, taking either the situation of this group in the previous period, or the average change in the population, as reference point. By contrast, we propose a measure of...

Defining the ‘global middle class’ as being neither poor nor rich in the developed world, we estimate the size of the global middle class in China and 33 other countries and analyze China’s expanding middle class in international perspective. China’s global middle class has grown rapidly...

Divergence between the evolution of GDP per capita and the income of a ‘typical’ household as measured in household surveys is giving rise to a range of serious concerns, especially in the USA. This paper investigates the extent of that divergence and the factors that contribute to it across...

We introduce two separate datasets (The Global Consumption Dataset (GCD) and The Global Income Dataset (GID)) making possible an unprecedented portrait of consumption and income of persons over time, within and across countries, around the world. The current benchmark version of the dataset...

This paper uses data from the key comparative sources available for the rich countries to examine how both real median incomes and income inequality have evolved from around 1980 through the Great Recession. There are striking differences across OECD countries in average real median income...

Combining consensus forecasts of growth of population and real incomes during 2014-35 with household income surveys for more than a hundred countries accounting for the bulk of the world economy, we project the income distribution in 2035 across all individuals in the world. We find that the...

We introduce two separate datasets (The Global Consumption Dataset (GCD) and The Global Income Dataset (GID)) containing an unprecedented portrait of consumption and income of persons over time, within and across countries, around the world. The benchmark version of the dataset presents...

Does uncertainty of labor earning over the life-time increase income inequality? - This paper finds that there is a direct positive relationship between life-time uncertainty and income inequality. Earlier studies single out the effect of uncertainty to pin point the effects of predictable...
