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...

We analyze exclusive contracts between health care providers and insurers in a model where some consumers choose to stay uninsured. In case of a monopoly insurer, exclusion of a provider changes the distribution of consumers who choose not to insure. Although the foreclosed care provider remains...

We study optimal risk adjustment in imperfectly competitive health insurance markets when high-risk consumers are less likely to switch insurer than low-risk consumers. First, we find that insurers still have an incentive to select even if risk adjustment perfectly corrects for cost differences...

This paper provides an analysis of the health insurance and health care consumption. A structural microeconomic model of joint demand for health insurance and health care is developed and estimated using full maximum likelihood method using Swiss insurance claims data for over 60,000 adult...

Following the financial crisis of 2008/9, there has been renewed interest in what Greenwald and Stiglitz dubbed ‘pecuniary externalities’. Two that affect borrowers and lenders balance sheets in pro-cyclical fashion are described, along with measures that might help curb their destabilising...

Deposit insurance schemes are becoming increasingly popular around the world and yet there is little understanding of how they should be designed and what their consequences are. In this Paper we provide a new rationale for the provision of deposit insurance. We analyse a model in which agents...

We characterize how public insurance schemes are constrained by hidden financial transactions. When non-exclusive private insurance entails increasing unit transaction costs, public transfers are only partly offset by hidden private transactions, and can influence consumption allocation. We show...

We study contracting between a consumer and an expert. The expert can invest in diagnosis to obtain a noisy signal about whether a low-cost service is sufficient or whether a high-cost treatment is required to solve the consumer’s problem. This involves moral hazard because diagnosis effort...

The Paper evaluates the German health care reform of 1997, using the individual number of doctor visits as outcome measure. A new econometric model, the Probit-Poisson-log-normal model with correlated errors, describes the data better than existing count data models. Moreover, it has an...

Performance indicators are increasingly used to regulate quality in health care and other areas of the public sector. We develop a model of contracting between a purchaser (principal) and a provider (agent) under the following scenarios: a) higher ability increases quality directly and...
