Economic evaluation of medical interventions aims to aid decision makers to achieve the goal of efficient use of health care resources at a community level by quantifying the tradeoffs between resources for medical care and the resulting health outcomes. Ideally, these evaluations would lead to...

Background: Medical cost-effectiveness analyses (CEA) traditionally treat patients as isolated individuals and neglect the effects of improvement in patients' health on the welfare of their family members. Recent analyses of the theoretical foundations of CEA suggest that cost-effectiveness...

Competition and prospective payment have been widely used to control health care costs but may together provide incentives to selectively reduce expenditures on high-cost relative to low-cost users. We use patient discharge and hospital financial data from California to examine the effects of...

Public technology assessments in general and Comparative Effectiveness Research (CER) in particular have been justified by offsetting benefits of improving patient health and reducing health care spending. However, little conceptual and empirical understanding exists concerning the quantitative...

We examine heterogeneity in the impacts of exposure to mixed-ability ‘comprehensive' schools in adolescence on long-term health and smoking behaviour. We explore the roles that cognitive and non-cognitive skills may play in moderating these impacts. We use data from the 1958 National Child...

Features of Part D gave rise to broad concern that the drug benefit would negatively impact prescription utilization among the six million dual eligible beneficiaries, either during the transition from state Medicaid to Part D coverage, or in the long-run. At the same time, Part D contained...

Under the assumption of no unmeasured confounders, a large literature exists on methods that can be used to estimating average treatment effects (ATE) from observational data and that spans regression models, propensity score adjustments using stratification, weighting or regression and even the...

Comparative effectiveness research (CER) can provide valuable information for patients, providers and payers. These stakeholders differ in their incentives to invest in CER. To maximize benefits from public investments in CER, it is important to understand the value of CER from the perspectives...

Reduced crime provides a key benefit associated with substance abuse treatment (SAT). Armed robbery is an especially costly and frequent crime committed by some drug-involved offenders. Many studies employ valuation methods that understate the true costs of robbery, and thus the true social...

We investigate how the scale of estimation in risk-adjustment models for health-care costs affects the covariate effect, where the scale of interest for the covariate effect may be different from the scale of estimation. As an illustrative example, we use claims data to estimate the incremental...
