The simplification of the tax code could be beneficial, but it is more than offset by its highly regressive nature.

A reduced corporate tax reduction is likely to grow GDP. Whether the overall tax plan is distributionally fair is another matter.

Though there is merit in cutting the corp tax and other capital taxes, with no other changes in policy, the fed gov will collapse.

The incentive effects are unclear to me. Some of the simplifications make sense but many of the changes look like hand-outs to the rich.

Since growth is likely to be little affected, debt to GDP will rise substantially, absent offsetting policies -- which are rarely enacted

By design, the plan increases debt by $1.5 trillion, net of increased-revenue effects. That seems to imply that debt to GDP will rise.

It seems unlikely that the optimistic growth figures are correct and so the budget deficit will rise unless government cuts are made.

The prospect of 5% GDP growth is absurdly unrealistic, and in its absence everyone agrees the proposed tax reform will contribute to debt.

José Scheinkman |

Provided one agrees that an increase in debt of 5 to 10 percentage points of GDP is substantial.
