The March Current Population Survey (CPS) is the primary data source for estimation of levels and trends in labor earnings and income inequality in the USA. Time-inconsistency problems related to top coding in theses data have led many researchers to use the ratio of the 90th and 10th...

Traditional cross-sectional measures find greater inequality in the United States than in industrialized Western European countries, but are unable to distinguish transitory from permanent inequality. With longitudinal data, we measure cross-sectional inequality during the 1980s using the...

Recent years have witnessed increased interest in issues of inequality and mobility in the labor market. Using data from the Panel Study of Income Dynamics and the German Socio-Economic Panel, we compare the labor earnings mobility of prime age men and women in the United States and Germany...

Reports that the Social Security Trust Fund will be exhausted sometime in the early part of the next century reinforce the need to make retirement policy in the United States more accommodating for those who want to work. While there is general agreement that disincentives to work at older ages...

This paper focuses on the movement of data-based social policy analysis from a single-country cross-section frame to a multi-country panel frame. It provides examples of policy insights this movement to panel data has permitted, both with respect to economic well-being and behavior--using data...

This paper uses kernel density estimation to show how after-tax household size-adjusted income changed between the peak years of the 1990s business cycle in Germany, Great Britain, Japan, and the United States. Great Britain and the United States experienced substantial growth in average income,...

Researchers considering levels and trends in the resources available to the middle class traditionally measure the pre-tax cash income of tax units or the pre-tax, post-transfer, size-adjusted income of households. Choices regarding the income measure and sharing unit to be analyzed, as well as...

Inconsistent censoring of top earnings in the public-use March Current Population Survey (CPS) is an important limitation in using it to measure labor earnings trends. Using less-censored internal CPS data, combined with Pareto estimates from it for internally censored observations, we create an...

Atkinson, Piketty, and Saez (2011) survey an important new literature using income tax-based data to measure the share of income held by top income groups. But changes in tax legislation that expand the tax base to include income sources (e.g. capital gains, dividends, etc.) disproportionately...
