This paper proposes a new motivation for information sharing in a decentralized channel consisting of a single manufacturer and two competing retailers. The manufacturer provides a common product to the retailers at the same wholesale price. Both retailers add their own values to the product and distribute it to consumers. Factors such as retail prices, values added to the product, and local ad...

We show that serial cost sharing for heterogeneous goods [4], and a large number of other cost sharing mechanisms, have the same strong strategic properties as serial cost sharing for homogenous goods [10], including uniqueness of the Nash equilibrium for all utility profiles and cost functions, dominance solvability, solvability in overwhelmed actions, and robustness to coalitional deviations....

OBJECTIVES To evaluate the effect of consumer cost sharing on use of physician-administered and patient self-administered specialty drugs for rheumatoid arthritis. DESIGN Multivariate statistical analysis of probability and use of physician-administered specialty drugs, patient self-injected specialty drugs, non-biologic disease-modifying anti-rheumatic drugs, and symptom relief drugs. Analys...

PURPOSE To evaluate the effect of patient cost-sharing on oral diabetes medication adherence and glycemic control. DESIGN Retrospective observational study. METHODOLOGY Medical and pharmacy claims from a managed care plan and electronic medical records (EMR) from a large physician organization in Oregon were used to identify a cohort with diabetes. Medication adherence and mean patient cost...

We study risk sharing between generations for a variety of realistic collective funded pension schemes, where pension benefits and contributions may depend on the funding ratio and the asset returns. The collective pension schemes organizing intergenerational risk sharing are optimized with respect to the generosity of pension benefits, the asset allocation and the risk allocation rules. We per...

We explore how private drug plans set cost-sharing in the context of Medicare Part D. While publicly-provided drug coverage typically involves uniform cost-sharing across drugs, we document substantial heterogeneity in the cost-sharing for different drugs within privately-provided plans. We also document that private plans systematically set higher consumer cost sharing for drugs or classes ass...

We investigate the ride-sharing assignment problem from an algorithmic resource allocation point of view. Given a number of requests with source and destination locations, and a number of available car locations, the task is to assign cars to requests with two requests sharing one car. We formulate this as a combinatorial optimization problem, and show that it is NP-hard. We then design an appr...
