资本回报的有效税收根据美国税法中的资本类型而有所不同。本文揭示了一个新的原因，最优的差别资本税。我们建立了一个包含两类资本--设备和结构--以及设备--技能互补的模型。在一个合理的假设下，我们表明，它是最优的税收设备在一个更高的税率比结构。在一个校准模型中，在向新的稳定状态过渡的过程中，最优税收差额从27个百分点上升到40个百分点。最优差别资本税的福利收益可以高达终身消费的0.4%。
The effective taxes on capital returns differ depending on capital type in the U.S. tax code. This paper uncovers a novel reason for the optimality of differential capital taxation. We set up a model with two types of capital – equipments and structures – and equipment-skill complementarity. Under a plausible assumption, we show that it is optimal to tax equipments at a higher rate than structures. In a calibrated model, the optimal tax differential rises from 27 to 40 percentage points over the transition to the new steady state. The welfare gains of optimal differential capital taxation can be as high as 0.4% of lifetime consumption.
