This report documents RAND analytical support to the Military Compensation and Retirement Modernization Commission (MCRMC). Using the Dynamic Retention Model, the report evaluates MCRMC’s proposed ...military compensation and retirement plan reforms, by service, for officers and enlisted personnel in both the active and reserve components. In addition to generating cost savings, the proposed reforms sustain the current force size and shape.
This research extends the dynamic retention model to simulate the transition to the steady state, providing researchers with the ability to assess the effects of workforce management policies both in ...the steady state and in the transition to the steady state as well as to assess the effects of alternative implementation strategies. It helps policymakers better understand workforce dynamics and how they respond to policy change.
We derive an a priori error estimate for the numerical solution obtained by time and space discretization by the finite volume/finite element method of the barotropic Navier–Stokes equations. The ...numerical solution on a convenient polyhedral domain approximating a sufficiently smooth bounded domain is compared with an exact solution of the barotropic Navier–Stokes equations with a bounded density. The result is unconditional in the sense that there are no assumed bounds on the numerical solution. It is obtained by the combination of discrete relative energy inequality derived in T. Gallouët, R. Herbin, D. Maltese and A. Novotný, IMA J. Numer. Anal. 36 (2016) 543–592. and several recent results in the theory of compressible Navier–Stokes equations concerning blow up criterion established in Y. Sun, C. Wang and Z. Zhang, J. Math. Pures Appl. 95 (2011) 36–47 and weak strong uniqueness principle established in E. Feireisl, B.J. Jin and A. Novotný, J. Math. Fluid Mech. 14 (2012) 717–730.
To offer insights into the challenges faced by active-duty service members deployed to Iraq and Afghanistan and their families in coping with these challenges, and the adequacy of defense manpower ...policy in assisting members and families, this monograph draws on the perspectives of economics, sociology, and psychology; provides a formal model of deployment and retention; reviews published work; reports on the results of focus groups conducted in each of the services; and presents findings from an analysis of survey data.
Owing to the armed conflicts in Iraq and Afghanistan, members of the US military have experienced very high rates of deployment overseas. Because military personnel have little to no control over ...their deployments, the military setting offers a unique opportunity to study the causal effect of major disruptions on marital dissolution. In this paper, we use longitudinal individual-level administrative data from 1999 to 2008 and find that an additional month in deployment increases the divorce hazard of military families, with females being more affected. A standard conceptual framework of marital formation and dissolution predicts a differential effect of these types of shocks depending on the degree to which they are anticipated when a couple gets married. Consistent with this prediction, we find a larger effect for couples married before 9/11, who clearly expected a lower risk of deployment than what they faced post 9/11.
Screening programs, such as annual mammography, are undertaken to reduce mortality and/or morbidity from chronic diseases such as cancer. Matched case-control studies have been used to assess the ...effectiveness of screening programs because of their relative simplicity and low cost. In such studies, the exposure history for controls consists of the number of screening examinations received prior to the date of diagnosis of the matched case. The authors know of no methodological evaluations that demonstrate the validity of such case-control studies. To examine the possible existence of bias due to design rules, the authors developed simple deterministic model, which is used to calculate expected screening and disease patterns in a cohort. Cases and matched controls are selected from the cohort, and their screening histories are used to calculate an odds ratio, as is commonly done in practice. Results utilizing this simple model suggest that systematic inclusion of the examination from which diagnosis is made, which is the approach typically used in practice, leads to a positive bias (odds ratio>1) in the absence of any real effect. Systematic exclusion of this examination appears to lead to a negative bias (odds ratio<1). Although this simple approach has several limitations, the results suggest that a commonly used method of conducting case-control studies may yield biased odds ratios. Possible methods to reduce this bias may exist, such as defining exposure intervals differently. Am J Epidemiol 1996;143:193–201
This research sought to understand how recent deployments have affected reenlistment by examining trends in deployments and reenlistments, developing a theoretical model, and conducting an ...econometric analysis of survey and administrative data to identify the effect of deployment, by service, on reenlistment. It also examined the role of reenlistment bonuses in maintaining reenlistment levels during the war on terrorism.
The collapse of the Soviet Union and the end of the Cold WarÑand then the terrorist attacks of September 11, 2001Ñtransformed the task of American foreign and defense policymaking. This book outlines ...the dimensions of that transformation and sketches new tools for dealing with the policy challengesÑfrom modeling and gaming, to planning based on capabilities rather than threats, to personnel planning and making use of "best practices" from the private sector.
Is the United States in danger of losing its competitive edge in science and technology? This volume reviews the arguments surrounding this issue and contrasts them with relevant data, including ...trends in research and development investment; information on the size, composition, and pay of the U.S. science and engineering workforce; and domestic and international education statistics. The authors conclude with recommendations for policymakers.
As the defense burden borne by reserve forces has increased, more attention has been paid to differences between retirement systems for the reserve and active components. This report analyzes the ...systems, discusses the importance of structuring compensation to enable management flexibility, considers obstacles and how they might be overcome, and provides a quantitative assessment of the reserve retention and cost effects of possible proposals.
