November 2010For Better or for Worse, But How About a Recession?
with Jeremy Arkes, Yu-Chu Shen: w16525
In light of the current economic crisis, we estimate hazard models of divorce to determine how state and national unemployment rates affect the likelihood of divorce. With 89,340 observations over the 1978-2006 period for 7633 couples from the 1979 NLSY, we find mixed evidence on whether increases in the unemployment rate lead to overall increases in the likelihood of divorce, which would suggest countercyclical divorce probabilities. However, further analysis reveals that the weak evidence is due to the weak economy increasing the risk of divorce only for couples in years 6 to 10 of marriage. For couples in years 1 to 5 and couples married longer than 10 years, there is no evidence of a pattern between the strength of the economy and divorce probabilities. The estimates are generally ...
August 2009The Effect of OEF/OIF Deployment Intensity on the Rate of Posttraumatic Stress Disorder Among Active Duty Population
with Yu-Chu Shen, Jeremy Arkes, Boon Wah Kwan, Lai Yee Tan, Thomas V. Williams: w15203
This study estimates the effect of deployment location and length on the risk of developing PTSD, relative to what it would be from the normal military operations. We use a random sample of activity-duty enlisted personnel serving between 2001 and 2006. We identify PTSD cases from TRICARE medical records and link deployment information from Contingent Tracking System. Comparing to those in other duties around the world, deployment to Iraq/Afghanistan increases the odds of developing PTSD substantially, with the largest effect observed for the Navy (OR=9.06, p<0.01) and the smallest effect for the Air Force (OR=1.25, p<0.01). A deployment longer than 180 days increases the odds of PTSD by 1.11 times to 2.84 times, depending on the service, compared to a tour under 120 days. For Army and N...
August 2008Why the DEA STRIDE Data are Still Useful for Understanding Drug Markets
with Jeremy Arkes, Rosalie Liccardo Pacula, Susan M. Paddock, Jonathan P. Caulkins, Peter Reuter: w14224
In 2001, use of the STRIDE data base for the purposes of analyzing drug prices and the impact of public policies on drug markets came under serious attack by the National Research Council (Manski et al., 2001; Horowitz, 2001). While some of the criticisms raised by the committee were valid, many of the concerns can be easily addressed through more careful use of the data. In this paper, we first disprove Horowitz's main argument that prices are different for observations collected by different agencies within a city. We then revisit other issues raised by the NRC and discuss how certain limitations can be easily overcome through the adoption of random coefficient models of drug prices and by paying serious attention to drug form and distribution levels. Although the sample remains a co...
