Spatial competition and quality: Evidence from the English family doctor market

Abstract

We examine whether family doctor firms in England respond to local competition by increasing their quality. We measure quality in terms of clinical performance and patient-reported satisfaction to capture its multi-dimensional nature. We use a panel covering 8 years for over 8000 English general practices. We measure competition as the number of rival doctors within a small distance and control for a large number of potential confounders. We find that increases in local competition are associated with increases in patient satisfaction and to a lesser extent in clinical quality. However, the magnitude of the effect is small.
