| Summary / Zusammenfassung | This research project deals with methods for evaluating the effects of a specific health care reform in Germany - where co-payments for prescription drugs were increased by up to 200 percent - on health care utilization. The data are from the German Socio-Economic Panel for the years 1995-1999 and the individual number of doctor visits is the outcome measure. The main purpose of the project is to extend the analysis beyond the usual estimation on average effects, and focus on the full distribution instead. This approach is motivated by the question whether the reform possibly had different effects in different parts of the distribution. Conceivably, for instance, the demand elasticity for doctor visits could be larger among rare users than among more frequent users (including the chronically sick). To identify such effects, more general methods than the ones used so far (Negative Binomial regressions, Poisson regressions) are required. These include a new probit-Poisson-log-normal model and the use of quantile regressions for counts. | ||
