The link between happiness and overall inequality is best studied using an index that incorporates different aspects of inequality, and is measured consistently in different countries. One such index is the degree to which happiness itself varies among individuals. Its correlation with both...

In this paper, we propose a new measure of horizontal equity that overcomes many of the shortcomings of previous proposed measures. Our starting point is the observation that a well-behaved social welfare function need not evaluate global' (vertical equity) differences in after-tax income using...

An index of Inequality is constructed which decomposes into two components, corresponding to vertical and "horizontal" equity respectively. Horizontal equity Is defined in terms of changes in the ordering of a distribution. The proposed index is a function to two inequality aversion parameters....

This paper presents a new framework for analyzing inequality that moves beyond the anonymity postulate. We estimate the determinants of sectoral choice and the joint distributions of outcomes across sectors. We determine which components of realized earnings variability are due to uncertainty...

I discuss available evidence about the evolution of top wealth shares in the United States over the last one hundred years. The three main approaches – Survey of Consumer Finances, estate tax multiplier techniques and capitalization method – generate generally consistent findings until...

A basic tenet of economic science is that productivity growth is the source of growth in real income per capita. But our results raise doubts by creating a direct link between macro productivity growth and the micro evolution of the income distribution. We show that over the entire period...

This paper considers data quality issues for the analysis of consumption inequality exploiting two complementary datasets from the Consumer Expenditure Survey for the United States. The Interview sample follows survey households over four calendar quarters and consists of retrospectively...

This paper summarizes the main findings of the recent studies that have constructed top incomeand wealth shares series over the century for a number of countries using tax statistics. Most countries experience a dramatic drop in top income shares in the first part of the century due to a...

We use a parametric method to estimate the income distribution for 191 countries between 1970 and 2006. We estimate the World Distribution of Income and estimate poverty rates, poverty counts and various measures of income inequality and welfare. Using the official $1/day line, we estimate that...
