<br/><br/> We compare the optimal insurance contribution rate and welfare levels for two opposite social insurance systems: a beveridgean one and a bismarckian one. The social contribution rates are decided by majority voting rule in both cases. In a model where agents earn heterogeneous incomes, we determine which system is preferred by which class of agents.Classification JEL: D7, H5
