Zusammenfassung:
We investigate the impact on mortality of the world’s first compulsory health insurance, established by Otto von Bismarck, Chancellor of the German Empire, in 1884. Employing a multi-layered empirical setup, we draw on international comparisons and difference-in-differences strategies using Prussian administrative panel data to exploit differences in eligibility for insurance across occupations. All approaches yield a consistent pattern suggesting that Bismarck’s Health Insurance generated a significant mortality reduction. The results are largely driven by a decline of deaths from infectious diseases. We present prima facie evidence that diffusion of new hygiene knowledge through physicians was an important channel.
