This paper analyzes optimal linear taxes on labor income and savings in a standard two-period life-cycle model with endogenous leisure demands in both periods and non-insurable income risks. Households are subject to skill shocks in both periods of the life-cycle. We allow for completely general...

We show in a two-period world with endogenous savings and two assets, one of them exhibiting a stochastic return, that an interest-adjusted income tax is optimal. This tax leaves a riskless component of interest income tax free and taxes the excess return with a special tax rate. There is no...

Should the realized risk premium be taxed or not? In a simple two asset portfolio model we analyze the optimal taxation rule when the economy faces aggregate risk. We show in an appropriate designed tax system, that the risk premium of the risky asset should be fully taxed if the households are...
