We analyze the effects of a mixed compensation (MC) scheme for specialists on
the quality of their healthcare services. We exploit a reform implemented in
Quebec (Canada) in 1999. The government introduced a payment mechanism
combining a per diem with a reduced fee per clinical service. Using a large
patient/physician panel dataset, we estimate a multi-state multi-spell hazard
model analogous to a difference-in-differences approach. We compute quality
indicators from our model. Our results suggest that the reform reduced the
quality of MC specialist services measured by the risk of re-hospitalization
and mortality after discharge. These effects vary across specialties
