The three worlds of welfare capitalism revisited

We introduce a new way to model the Bismarckian social insuance system, stressing its corporatist dimension. Comparing the Beveridgean, Bismarckian and Liberal systems according to the majority voting rule, we show that for a given distribution of risks inside society, the Liberal system wins if the inequality of income is low, and the Beveridgean system wins if the inequality of income is high. Using a utilitarian criterion, the Beveridgean system always dominates and the Bismarckian system is preferred to the Liberal one.
