Evaluating the Labor Market Performance of Veterans Using a Matched Comparison Group Design
利用1986和1992年预备役调查数据，通过匹配对照组设计，估计现役服役对平民收入的影响，发现平均影响为3%，但军官和士兵、不同种族和服役时期的效果差异显著。
A key concern in estimating the effect of military service on civilian earnings is bias from unmeasured differences between military veterans and nonveterans. The effects of activeduty service are estimated using the 1986 and 1992 Reserve Components Surveys, which permit a matched comparison between reservists who are veterans and reservists without active-duty service. Because military entrance requirements are identical for the reserves and active duty, estimated treatment effects embody control for selection by the military and selection by workers for a form of military service. Results are presented for officers and\nenlisted personnel and by race and era of service. The average impact of active-duty service on civilian earnings is 3 percent among the reservist population, but this average reflects treatment effects of essentially zero for enlisted personnel and 10 percent for officers. Among white enlisted personnel, veteran effects are negative but small. Treatment effects for African-American veterans average about 5 percent. Vietnam-era white draftees are found to have suffered an approximate 5 percent wage penalty and volunteers little penalty, but\nestimates from the reservist sample are likely to understate negative effects from Vietnamera service.
