The interaction between patient shortage and patients waiting time

We study the interaction between patient shortage and patients' waiting time to get an appointment. From a theoretical model we predict that physicians experiencing a shortage of patients offer their patients a shorter waiting time than their unconstrained colleagues. This happens because a shorter waiting time is expected to lower the threshold for seeking care, and hence, to increase the number of patient-initiated contacts. But it also happens because a shorter waiting time can be a mean to attract new patients. The hypotheses are supported by some preliminary results from a sample of Norwegian general practitioners participating in a capitation trial.
