"Private insurance for prescription drugs is characterized by two regimes: flat copayments and variable co-insurance. We develop a simple model to show that patient compliance is lower under coinsurance due to uncertainty in cost-sharing. Empirically, we derive comparable models for compliance...

A health insurer's Medical Loss Ratio (MLR) is the share of premiums spent on medical claims. As part of the goal of reducing the cost of health care coverage, the Affordable Care Act introduced minimum MLR provisions for all health insurance sold in fully-insured commercial markets as of 2011,...

In this paper, we address the issue of spurious correlation in the production of health in a systematic way. Spurious correlation entails the risk of linking health status to medical (and nonmedical) inputs when no links exist. This note first presents the bounds testing procedure as a method to...

Consumers' health plan choices are highly persistent even though optimal plans change over time. This paper separates two sources of inertia, inattention to plan choice and switching costs. We develop a panel data model with separate attention and choice stages, linked by heterogeneity in...
