Individual moral hazard engendered by health insurance and monopolistic production are both typical phenomena of drug markets. We develop a simple model containing these two elements and evaluate the market equilibrium on the basis of consumer and social welfare. The consumer welfare criterion...

In dieser Arbeit sollen die Konsequenzen einer unhinterfragten Konsolidierungspolitik untersucht werden. Dazu wird ein einfaches Modell ,optimaler öffentlicher Verschuldung' konstruiert, das sowohl als Ausgangspunkt für die Erklärung der Konsolidierungsbehühungen dient, als auch mögliche...

The paper reviews models of the physician-patient relationship to derive testable hypotheses about the relation between health, demand for medical services and patient's compliance. The models imply that in addition to existing information asymmetries the actions that physician and patient...

The relationship between physician and patient has been discussed intensively in the literature. Nevertheless, they neglect the fact that the production of health not only depends on the medical services supplied by the physician but is also influenced by the patient's compliance. We present a...

This paper examines the competition of nonprofit sickness funds in the market for supplementary health insurance. We investigate product quality strategies when quality is costly and the sickness funds are competing for customers. As long as the sickness funds choose the qualities for...

This paper analyses simultaneous regulation of cost and quality when firms have private, correlated information about productivity and the regulator receives a signal about quality. It is shown that managerial effort and expenditures on quality are positively correlated in the optimal contract....

In many markets insurers are barred from price discrimination based on con- sumer characteristics like age, gender, and medical history. In this paper, I build on a recent literature to show why such policies are inefficient if consumers differ in their willingness-to-pay for insurance...

We consider a therapeutic market with potentially three pharmaceutical firms. Two of the firms offer horizontally differentiated brand-name drugs. One of the brand-name drugs is a new treatment under patent protection that will be introduced if the profits are sufficient to cover the entry...

This paper studies the impact of hospital competition on waiting times. We use a Salop-type model, with hospitals that differ in (geographical) location and, potentially, waiting time, and two types of patients; high-benefit patients who choose between neighbouring hospitals (competitive...
