Researchers frequently require a quantitative understanding of the likely consequences of different actions before they can advise decisionmakers and design effective policies. RAND develops and uses statistical, econometric, and other exploratory models and simulations to analyze the potential outcomes of different policies in a range of areas such as transportation usage, health care, patient safety, and military campaigns.

RAND Europe's "Choice Modelling and Valuation" group provides specific expertise in using discrete choice modeling methods to understand and predict choice behavior as a result of policy intervention. This work is frequently undertaken in the transport sector, but expertise is increasingly applied in sectors including health and social care, post and communications, and provision of regulated consumer services.
REPORT
Together this and two companion monographs demonstrate a method, model, and simulation that the U.S. Army can use to analyze and manage portfolios at any stage of the research and development process. This monograph expands and applies RAND's portfolio analysis and management (PortMan) method to address the problem of selecting Army engineering and manufacturing development projects in order to develop affordable systems.

This study assesses, from a Swedish societal perspective, the cost effectiveness of interferon β-1b (IFNB-1b) after an initial clinical event suggestive of multiple sclerosis (MS) (ie, early treatment) compared with treatment after onset of clinically definite MS (CDMS) (ie, delayed treatment).
REPORT
This document distills and synthesizes the proceedings of a workshop in which experts in the field of regulatory analysis and terrorism risk examined alternative approaches for estimating the benefits of regulations designed to reduce the risks of terrorist attacks in the United States. The workshop gave rise to several recommendations for improving the modeling and data collection that support the benefit-cost analysis of terrorism…
REPORT
In consideration of the many challenges associated with Qatar's continued growth and demographic changes, the government of Qatar is interested in updating its school transportation system (STS). This volume assesses parents' and school administrators' perspectives on Qatar's STS, identifies a vision and goals for the STS, and discusses strategies to achieve the vision and better align Qatar's STS with international norms. This is the…
REPORT
Pattern and trend analysis and systematic randomness can be used to position U.S. border security personnel and equipment effectively for interdiction, and in some circumstances the combined approach is competitive with perfect surveillance.
NEWS RELEASE
The RAND Corporation, Risk Management Solutions, Inc. (RMS) and private investors have launched a company named Praedicat, Inc., that will provide consulting services and software to the property and casualty insurance industries.
REPORT
This report documents work to update the Application System of the Sydney Strategic Model (STM). The Application System implements models of frequency, mode and destination choice for each of the nine travel purposes in the STM.
JOURNAL ARTICLE
As health care reform expands the use of "report cards" to grade health care providers, greater attention to reporting methods may be needed to assure the quality of such efforts.
JOURNAL ARTICLE
This study seeks to develop a new prognostic model, the Patient-Reported Outcome Mortality Prediction Tool (PROMPT), for six-month mortality in community-dwelling elderly patients.
REPORT
Considering the challenges associated with continued growth and demographic changes, the government of Qatar is interested in updating its school transportation system (STS). This volume assesses the perspectives of parents and school administrators, identifies a vision for the STS, and discusses strategies to achieve it.
REPORT
Eliminating a key part of health care reform that requires all Americans to have health insurance would sharply lower the number of people gaining coverage, but would not dramatically increase the cost of buying policies through new insurance exchanges.
RESEARCH BRIEF
An analysis of the effects of implementing the Affordable Care Act without an individual mandate found that over 12 million people who would have otherwise signed up for coverage will be uninsured and premium prices will increase by 2.4 percent.

RESEARCH BRIEF
Describes a vision for updating Qatar's school transportation system and identifies strategies for achieving the proposed vision.
PROJECT
RAND Europe is expanding the original traffic model it developed for Copenhagen to include time-of-day choice for car drivers. Doing so will allow city planners to assess the effectiveness of different charging policies aimed at reducing congestion levels.
REPORT
Different market segments have varying postal service needs, according to RAND Europe research conducted for the European Commission. All consumers value parcel services, reliability, and low levels of loss, but big businesses value letter services more than small or medium businesses or the public.
REPORT
This report documents work to update the Population Synthesiser component of the Sydney Strategic Model (STM). The Population Synthesiser generates forecasts of the future Sydney population by spatial area and socio-economic segment.
JOURNAL ARTICLE
The authors use simulation studies to examine performance (bias, mean squared error, coverage probabilities, and power) of models using all three time scales when the primary exposure of interest depends on calendar time.
REPORT
The methods employed, as well as those recommended for future studies, are applicable to any law enforcement agency interested in attracting and identifying high-quality applicants more efficiently.
