Abstract
This paper studies the role of social insurance as a redistributive mechanism in presence of an optimal (linear or general) income tax. It considers a second-best setting with two unobservable individual characteristics: ability, measured by the wage rate and risk, measured by the probability of incurring a loss. It shows that both tax progressivity and the optimal level of social insurance crucially depend on the correlation between ability and risk.
