This paper uses Social Security Administration longitudinal earnings micro data since 1937 to analyze the evolution of inequality and mobility in the United States. Earnings inequality follows a U-shape pattern, decreasing sharply up to 1953 and increasing steadily afterwards. We find that...

This paper uses Social Security Administration longitudinal earnings micro data since 1937 to analyze the evolution of inequality and mobility in the United States. Annual earnings inequality is U-shaped, decreasing sharply up to 1953 and increasing steadily afterward. Short-term earnings...

We rely on the Master Beneficiary File to document a number of facts regarding claiming of Social Security benefits and quality of date of birth data in administrative files. We then assess the impact of changes in retirement incentives that have taken place since 2000 on claiming. We find...

This paper presents new homogeneous series on top wealth shares from 1916 to 2000 in the United States using estate tax return data. Top wealth shares were very high at the beginning of the period but have been hit sharply by the Great Depression, the New Deal, and World War II shocks. Those...

Anecdotal evidence suggests that Social Security Disability Insurance (SSDI) beneficiaries intentionally restrain, or “park,†their earnings at a level below substantial gainful activity to retain cash benefits. But empirical evidence documenting such behavior is scant. This article in...

We study the evolution of individual labor earnings over the life cycle using a large panel data set of earnings histories drawn from U.S. administrative records. Using fully nonparametric methods, our analysis reaches two broad conclusions. First, earnings shocks display substantial deviations...

Two changes have been made recently to rules governing the Social Security program: the retirement earnings test was eliminated in 2000 for people aged 65–69, and the full retirement age (FRA) for people born in 1938 or later was scheduled to gradually increase in two-month increments until...

This paper studies how recessions affect individual income risk. We employ a unique and confidential administrative data set with tens of millions of observations on individual earnings histories from the Social Security Administration records. We use a dataset that is a 10% random sample of the...
