Abstract

[eng] The Induced Demand Hypothesis: an Economic Assessment by Lise Rochaix and Stéphane Jacobzone . In health economics the induced demand hypothesis is bringing about a transformation in the way health-care demand is perceived. It posits that health-care demand does not simply reflect choice in terms of patient utility but can also be determined by a doctor's implicit motivation. This extremely polemical hypothesis has formed the basis for numerous empirical studies. In this paper we demonstrate that the controversy arises partly from the exact formulation of the hypothesis. A detailed analysis of available work on the extent of induced demand leads to a qualified judgement. On the empirical level, the academic debate seems to be partly closed, although it has not been definitively resolved given the limitations of the tools. Nevertheless, this economic assessment underlines the weight of the incentives to which doctors are exposed in the practice of their profession. This is not without an effect on discussion of payment systems for providers and may shed light on certain economic policy choices. [fre] L'hypothèse de demande induite : un bilan économique par Lise Rochaix et Stéphane Jacobzone . En économie de la santé, l'hypothèse de demande induite conduit à transformer la perception de la demande de soins. Celle-ci ne refléterait pas seulement les choix en termes d'utilité du patient, mais pourrait aussi être déterminée par les motivations implicites du médecin. Cette hypothèse très discutée a fait l'objet de multiples études empiriques. Nous montrons ici que les controverses dépendent pour partie de la formulation exacte de l'hypothèse. Une analyse fouillée des travaux disponibles quant à l'ampleur de la demande induite conduit à une appréciation nuancée. Au niveau empirique, le débat académique semble en partie clos et n'est pas définitivement tranché, compte tenu des limites des outils. Néanmoins, un tel bilan souligne l'importance des incitations auxquelles sont exposés les médecins dans leur pratique. Ceci n'est pas sans incidence quant à la réflexion en termes de mécanismes de rémunération des offreurs et peut éclairer certains choix de politique économique.
