We investigate the presence of moral hazard and advantageous or adverse selection in a market for supplementary health insurance. For this we specify and estimate dynamic models for health insurance decisions and health care utilization. Estimates of the health care utilization models indicate...

This paper examines the impact of coinsurance exemption for prescription medicines applied to elderly individuals in Spain after retirement. To evaluate this coinsurance change we use a rich administrative dataset that links pharmaceutical consumption and hospital discharge records for the full...

This research uses the input-oriented Data Envelopment Analysis (DEA) approach to examine the efficiency of the U.S. health insurers. It shows that more insurers are less efficient than the previous sample year; however, the results suggest that the federal health care reform have no significant...

States have been enacting tort reforms to reduce the liability of physicians conducting malpractice. However, tort reform may create a moral hazard because physicians may take less care due to reduced liability. This paper investigates whether physician moral hazard presents after tort reform. I...

Existing studies estimate health insurance-induced increases in medical care expenditure by examining medical care decisions that are aggregated to the annual level. Using employer-employee matched data from the Medical Expenditure Panel Survey, I quantify the moral hazard effect of insurance on...

Microeconomic theory predicts that if patients are fully insured and providers are paid fee-for-service, utilization of medical services exceeds the efficient level (‘moral hazard effect’). In Switzerland, both demand-side and supply-side cost sharing have been introduced to mitigate this...

In this note, we generalize the results obtained by Barday and Lesur (2005) by considering a bivariated non separable utility function. We characterize optimal health insurance contracts. Moreover, we show that under moral hazard a sufficiently high risk aversion implies that the optimal...
