The present paper examines whether supplier inducement exists for prim
ary physicians' services in Norway. Our model assumes optimization beh
aviour of the physician. The research design is adapted to the institu
tional setting of Norwegian primary physician services, where there is
a fixed fee schedule. According to our model, the physician has three
choices: to ration services, to supply an optimal amount of services
or to induce demand for services. The analyses revealed no indication
of inducement with respect to physician-initiated visits. However, sup
plier inducement effects were found for provision of laboratory tests.
