Although physicians are often expected to be gatekeepers to health insurance benefits such as paid sick leave, research indicates a substantial reluctance to reject patient requests for sickness certificates. We show that private information on the patient's part creates a conflict between the...

We develop a dynamic model of hospital competition where (i) waiting times increase if demand exceeds supply; (ii) patients choose a hospital based in part on waiting times; and (iii) hospitals incur waiting time penalties. We show that, whereas policies based on penalties will lead to lower...

Primary care physicians have two roles: the healer and the gatekeeper. We show that, due to information asymmetries, they cannot be expected to fulfill the latter role. Better gatekeepers will be poorer healers; hence all patients, both truly sick and shirkers, will strictly prefer physicians...

We analyze prescription behavior of physicians in the public and private sector. We study two major diseases for which an effective, widely accepted low-cost treatment and alternative, more expensive treatments are available. We find that private sector physicians are more likely to prescribe...

We investigate the effect of reputational motivation on output in a scenario of overprovision of medical treatment. We assume that physicians differ in their degree of altruism, enjoy being perceived as good but dislike being perceived as greedy. We show that better reputational motivation...

We consider an economy where most of the health care is publicly provided,and where there is waiting time for several types of treatments. Privatehealth care without waiting time is an option for the patients in the publichealth queue. We show that although patients with low waiting costs...

Suppliers who are better informed than purchasers, such as physicians treating insured patients, often have discretion over what to provide. This paper shows how, when the purchaser observes what is supplied but can observe neither recipient type nor the actual cost incurred, optimal provision...

This paper compares health care systems. It looks beyond normal academic, political, or journalistic rhetoric, by exactly sticking to facts, i.e. empirical data (in particular data provided by the WHO) and comprehensive case study analyses. The paper finds that a number of myths and common...
