摘要：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 safe component of interest income tax free
and taxes the excess return with a special tax rate. There is no trade-off
between risk allocation and efficiency in intertemporal consumption. Both
goals are reached. As the resulting tax system divides income into three
parts, the tax can also be called a Triple Income Tax. This distinction and a
special tax rate on the excess return is necessary in order to have an optimal
risk shifting effect.
