text: 'We explore how competition between physicians affects medical service provision.
Previous research has shown that, without competition, physicians deviate from
patient‐optimal treatment under payment systems like capitation and fee‐for‐service.
Although competition might reduce these distortions, physicians usually interact
with each other repeatedly over time and only a fraction of patients switches
providers at all. Both patterns might prevent competition to work in the desired
direction. To analyze the behavioral effects of competition, we develop a theoretical
benchmark that is then tested in a controlled laboratory experiment. Experimental
conditions vary physician payment and patient characteristics. Real patients benefit
from provision decisions made in the experiment. Our results reveal that, in line
with the theoretical prediction, introducing competition can reduce overprovision
and underprovision, respectively. The observed effects depend on patient characteristics
and the payment system, though. Tacit collusion is observed and particularly pronounced
with fee‐for‐service payment, but it appears to be less frequent than in related
experimental research on price competition. '
