Taxing Risky Investment
Michael P. Devereux (Oxford University Centre for Business Taxation)
This paper re-examines the impact of consumption and capital income taxes on (a) the incentive to undertake risky investment and (b) the revenue generated from such taxes. It challenges a well-known claim in the literature that a capital income tax with full loss offset can leave incentives to invest "basically unaffected" because the tax liability is offset by a reduction in the post-tax risk of the investment. Instead, it argues that such a tax would have a significantly negative impact on the incentive to invest.
