Did tax cuts generate enough growth to offset their revenue loss?
Core argument: GDP grew 2.9% in 2018 against the CBO's pre-TCJA projection of 3.3% real growth, which Gravelle and Marples read as a smaller-than-anticipated first-year effect from the Tax Cuts and Jobs Act.
In 2018, GDP grew at 2.9%, aligning with the CBO's pre-TCJA [Tax Cuts and Jobs Act] projection, indicating a minimal first-year economic impact from the tax cuts. Despite significant investment growth, asset growth patterns did not align with expected supply-side incentives. The CBO projected a 3.3% real GDP growth for 2018, but actual growth was 2.9%, suggesting a smaller-than-anticipated effect of the tax revision. The revenue loss from the tax cut was estimated at 1.2% of GDP, requiring a 6.7% GDP increase to offset it, yet observed feedback was only 0.3% of GDP, covering less than 5% of the needed growth to balance the revenue loss.
