Taxation of Corporate Capital Income: Tax Revenues Versus Tax Distortions
发现，在考虑不确定性后，对企业收入征税基本不影响投资和储蓄激励，甚至可能提高效率，因为政府同时吸收了预期收益和风险，两者效应相互抵消。
This paper shows that when uncertainty is taken into account explicitly, taxation of corporate income can leave corporate investment incentives, and individual savings incentives, basically unaffected, in spite of the sizable tax revenues collected. In some plausible situations, such taxes can increase efficiency. The explanation for these surprising results is that the government, by taxing capital income, absorbs a certain fraction of both the expected return and the uncertainty in the return. While investors as a result receive a lower expected return, they also bear less risk when they invest, and these two effects are largely offsetting.
