Penn Wharton: Warren's Wealth Tax Would Raise $1.5 Trillion Less Revenue, Reduce GDP And Wages

Penn Wharton Budget Model, Senator Elizabeth Warren's Wealth Tax: Projected Budgetary and Economic Effects:

Penn Wharton Budget Model (PWBM) projects that Senator Warren’s proposed wealth tax, if implemented in 2021, would raise between $2.3 trillion (including macroeconomic effects) and $2.7 trillion (not including macroeconomic effects) in additional revenue in the 10-year window 2021 - 2030 while reducing GDP in 2050 by about 1 to 2 percent, depending on how the money is spent.

• Senator Elizabeth Warren has proposed a wealth tax equal to 2 percent of net worth above $50 million and 6 percent of net worth above $1 billion, which her campaign estimates would raise $3.75 trillion over 10 years.
• PWBM estimates that the proposal would raise about $2.7 trillion over fiscal years 2021-2030, not including macroeconomic effects. Including macroeconomic effects, PWBM estimates that the proposal would raise about $2.3 trillion over the same period.
• PWBM projects that the proposal would reduce GDP by 0.9 percent in 2050 under the standard budget scoring convention that additional revenues reduce the deficit. If the revenues were instead spent on public investments, PWBM projects GDP in 2050 would fall between 1.1 and 2.1 percent, depending on the productivity of the investment. Average hourly wages in the economy in 2050, including wages earned by households not directly subject to the wealth tax, would fall between 0.8 and 2.3 percent due to the reduction in private capital formation.
