Less social health insurance, more private supplementary insurance? Empirical evidence from Germany
Based on individual level data from Germany, we analyze the effect of changes in the compulsory benefit package of the social health insurance on the demand for supplementary private insurance, employing a difference-in-differences approach. The focus is on the exclusion of dental prostheses from the benefit package in 1997 and its re-inclusion in 1999. Individuals born prior to 1979 serve as control group because only the young were affected by the reform. No significant effect on the demand for supplementary health insurance is found. Thus, the notion of clients making informed choices about their health insurances’ coverage is not supported.
