Firm-Level Early Intervention Incentives
The declining economic status of people with disabilities and the predicted 2016 depletion of the Social Security Disability Insurance (DI) Trust Fund have generated considerable interest in proposals for reforming the DI program. Some proposals would hold firms partially responsible for a portion of the DI benefits paid to their recent employees. We analyze the implications of this approach for employers and workers in general, and specifically …
Trade Adjustment
We analyze the effect of exposure to international trade on earnings and employment of U.S. workers from 1992 through 2007 by exploiting industry shocks to import competition stemming from China’s spectacular rise as a manufacturing exporter paired with longitudinal data on individual earnings by employer spanning close to two decades. Individuals who in 1991 worked in manufacturing industries that experienced high subsequent import growth garner…
The Nature of Countercyclical Income Risk
We study business cycle variation in individual earnings risk using a confidential and very large data set from the US Social Security Administration. Contrary to past research, we find that the variance of idiosyncratic shocks is not countercyclical. Instead, it is the left-skewness of shocks that is strongly countercyclical: during recessions, large upward earnings movements become less likely, whereas large drops in earnings become more likely…
Earnings Inequality and Mobility in the United States
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 mobility measures are stable over the full period except for a temporary surge during World War II. Virtually all of the increase in the variance in annual (log…
