The employment effects of terminating disability benefits
This paper examines the employment of individuals in the United States who lost disability insurance eligibility after the 1996 removal of drug and alcohol addictions as qualifying conditions.
Abstract
Few Social Security Disability Insurance (DI) beneficiaries return to the labor force, making it hard to assess their likely employment in the absence of benefits. Using administrative data, I examine the employment of individuals who lost DI eligibility after the 1996 removal of drug and alcohol addictions as qualifying conditions. Approximately 22 percent started working at levels that would have disqualified them for DI, an employment response that is large relative to their work histories. Those who received DI for 2-3 years had the largest response, suggesting that a period of public assistance may maximize the employment of some disabled individuals
Paper Session I-D - A Study of Alternative Technologies to Compressed Air Self-Contained Breathing Apparatus
The Kennedy Space Center Fire Department is tasked with the rescue of flight crew members of the United States Space Shuttle fleet for launch and landing at the Kennedy Space Center and two transatlantic emergency landing sites. This research project addresses the problem of how conventional compressed air technology used in self-contained breathing apparatus SCBA limits the Firefighters at Kennedy Space Center in performing their mission of astronaut rescue.
The purpose of this research project is to examine alternative technologies to compressed air SCBA in hopes of ensuring that the Astronaut Rescue Team members are equipped with an SCBA that best meets their needs

Liquidity, Activity, Mortality
We document a within-month mortality cycle where deaths decline before the 1st day of the month and then spike after the 1st. This cycle is present across a wide variety of causes and demographic groups. A similar cycle exists for a range of activities, suggesting the mortality cycle may be due to short-term variation in levels of activity. We provide evidence that the within-month activity cycle is generated by liquidity. Our results suggest a causal pathway whereby liquidity problems reduce activity, which in turn reduces mortality. These relationships help explain the pro-cyclic nature of mortality.
The White/Black Educational Gap, Stalled Progress, and the Long Term Consequences of the Crack Epidemic
We propose the rise of crack cocaine as an explanation for the end to the convergence in black-white educational outcomes beginning in the mid-1980s. After constructing a measure of the arrival of crack arrival in cities and states, we first show there are large increases in incarceration and murder rates after the arrival of the drug. We show that the emergence of crack accounts for between 39 and 71 percent of the fall in black male high school graduation rates. The results suggest that, in line with human capital theory, educational investments declined in response to decreased returns to schooling
