This paper summarizes the main findings of a recent literature that has constructed top income shares time series over the long-run for more than 20 countries using income tax statistics. Top incomes represent a small share of the population but a very significant share of total income and total...

This paper provides estimates of federal tax rates by income groups in the United States since 1960, with special emphasis on very top income groups. We include individual and corporate income taxes, payroll taxes, and estate and gift taxes. The progressivity of the U.S. federal tax system at...

and 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 precipitous drop in large wealth holdings during the wars and depression shocks. Top income shares do...

This paper presents new homogeneous series on top shares of income and wages from 1913 to 1998 in the US using individual tax returns data. Top income and wages shares display a U-shaped pattern over the century. Our series suggest that the 'technical change' view of inequality dynamics cannot...

This paper presents new findings on global inequality dynamics from the World Wealth and Income Database (WID.world), with particular emphasis on the contrast between the trends observed in the United States, China, France, and the United Kingdom. We observe rising top income and wealth shares...

This paper combines tax, survey, and national accounts data to estimate the distribution of national income in the United States since 1913. Our distributional national accounts capture 100% of national income, allowing us to compute growth rates for each quantile of the income distribution...

The top 1 percent income share has more than doubled in the United States over the last thirty years, drawing much public attention in recent years. While other English speaking countries have also experienced sharp increases in the top 1 percent income share, many high-income countries such as...

This paper develops a realistic, tractable theoretical model that can be used to investigate socially-optimal capital taxation. We present a dynamic model of savings and bequests with heterogeneous random tastes for bequests to children and for wealth per se. We derive formulas for optimal tax...

This paper presents a model of optimal labor income taxation where top incomes respond to marginal tax rates through three channels: (1) standard labor supply, (2) tax avoidance, (3) compensation bargaining. We derive the optimal top tax rate formula as a function of the three corresponding...
