摘要:Germany is one of the few OECD countries with a two-tier system of statutory and
primary private health insurance. Both types of insurance provide
fee-for-service insurance, but chargeable fees for identical services are more
than twice as large for privately insured patients than for statutorily insured
patients. This price variation creates incentives to induce demand primarily
among the privately insured. Using German SOEP 2002 data, I analyze the effects
of insurance status and district (Kreis-) level physician density on the
individual number of doctor visits. The paper has four main findings. First, I
find no evidence that physician density is endogenous. Second, conditional on
health, privately insured patients are less likely to contact a physician but
more frequently visit a doctor following a first contact. Third, physician
density has a significant positive effect on the decision to contact a physician
and on the frequency of doctor visits of patients insured in the statutory
health care system, whereas, fourth, physician density has no effect on
privately insured patients' decisions to contact a physician but an even
stronger positive effect on the frequency of doctor visits than the statutorily
insured. These findings give indirect evidence for the hypothesis that
physicians induce demand among privately insured patients but not among
statutorily insured.
