An Analysis of Senator Warren’s ‘Real Corporate Profits Tax’

Sen. Elizabeth Warren introduced a 7 percent surtax on corporate profits called the “Real Corporate Profits Tax.” We estimate that this tax would reduce the incentive to invest in the United States, and result in a 1.9 percent smaller economy, a 3.3 percent smaller capital stock, and 1.5 percent lower wages.
