Retention and retirement: The case of the U.S. military

The military retirement system provides an immediate, lifetime, inflation-protected annuity to personnel who complete 20 or more years of service. The cost of this system has risen substantially in the past 15 years, and the system's actuarial costs now comprise almost one-third of total military manpower costs. Because of its importance in the total military compensation system, the military retirement system exerts a significant influence on the age structure of the force and on personnel turnover patterns. This article evaluates the relative efficiency of the current retirement system by comparing it with two recently proposed alternatives, one by a presidential commission and one by the Department of Defense. It estimates the impact of these proposed alternatives on the military personnel force structure and on manpower costs. It is concluded that these alternatives would provide a force as capable as today's force at significantly lower cost.Order of authorship determined alphabetically.
