Large multinational tech firms such as Facebook, Apple, Microsoft, Google, and Amazon can benefit much from the G.O.P. tax reform. A recent stock research report assumes the effective U.S. corporate income tax rate declines from 35% to 21%-22% in January 2018 with no subsequent changes in international taxes and all other aspects of the U.S. tax legislation. Specifically, Google will receive tax benefits of more than $2 billion in 2018, Facebook expects to attain tax cost reductions of $1.5 billion, and Amazon will enjoy about $1 billion in tax credits. Also, these tech firms plan to expand their capital expenditures with preferential tax provisions in the Trump administration's current tax reform. Overall, these tech firms can expect to achieve hefty tax benefits in the range of $4.5 billion to $5 billion in the 5-year period from 2018 to 2022.

Harvard macrofinance professor Greg Mankiw entertains a key policy question: how much would the average real wage rise for each $1 decrease in the typical firm tax outlay ceteris paribus? The answer is likely to be $1.5 to $2 in real wage terms for each $1 tax cut, or equivalently $4,000 to $ 9,000 per capita per year. Several eminent economists such as Brad DeLong, Larry Summers, and John Cochrane suggest that if we take into account positive externalities and positive returns to the scale of capital usage, the resultant real wage increase can turn out to be higher. An open controversy clouds the fundamental view of whether these massive tax cuts may exacerbate fiscal inequality in America.
