Competition and physician behaviour: Does the competitive environment affect the propensity to issue sickness certificates?

Kurt R. Brekke (Department of Economics, Norwegian School of Economics) ; Tor Helge Holmäs (Uni Research Rokkan Centre) ; Karin Monstad (Uni Rokkan Centre) ; and Odd Rune Straume (NIPE/University of Minho) ask Competition and physician behaviour: Does the competitive environment affect the propensity to issue sickness certificates?

ABSTRACT: Competition among physicians is widespread, but compelling empirical evidence on the impact on service provision is limited, mainly due to lack of exogenous variation in the degree of competition. In this paper we exploit that many GPs, in addition to own practice, work in local emergency centres, where the matching of patients to GPs is random. This allows us to observe the same GP in two dfferent competitive environments; with competition (own practice) and without competition (emergency centre). Using rich administrative patientlevel data from Norway for 2006-14, which allow us to estimate high-dimensional fixed-effect models to control for time-invariant patient and GP heterogeneity, we and that GPs with a fee-for-service (fixed salary) contract are 11 (8) percentage points more likely to certify sick leave at own practice than at the emergency centre. Thus, competition has a positive impact on GP´s sick listing that is reinforced by financial incentives.
