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