The paper evaluates the German health care reform of 1997, using the individual number of doctor visits as outcome measure and data from the German Socio- Economic Panel for the years 1995-1999. A number of modified count data models allow to estimate the effect of the reform in different parts...

The paper evaluates the German health care reform of 1997, using the individual number of doctor visits as outcome measure. A new econometric model, the Probit-Poisson-log-normal model with correlated errors, describes the data better than existing count data models. Moreover, it has an...

This study exploits a natural experiment in Belgium to estimate the effect of co-payment increases on the demand for physician services. It shows how a differences-in-differences estimator of the price effects can be decomposed into effects induced by the common average proportional price...
