Titre traduit: How to regulate french public hospitals?
The purpose of this paper is to study hospital costs in the event of introduction of a Prospective Payment System in France. We use a nested three dimensional database (stays-hospitals-years) in order to identify hospital unobservable heterogeneity and a transitory moral hazard component of cost variability. Econometric estimate are performed on a sample of 7,314 stays for acute myocardial infarction observed in 36 French public hospitals over the period 1994 to 1997. Transitory moral hazard is far from negligible: its estimated standard error is about 50% of the standard error we estimate for cost variability due to permanent unobservable heterogeneity between hospitals. Simulations show that a cost reduction of about 16% can be expected from implementation of a payment system, which allows for permanent unobserved heterogeneity and eliminates only transitory moral hazard.
