White House forecasts "big, beautiful bill" would drive stunning economic growth

• They put that number at 2.9% to 3.5% in the long run.
• They see the legislation boosting investment by 10% to 15% in the next four years, and boosting wages by $6,000 to $11,000 per worker.

What they're saying: "All of this is a result of low tax rates incentivizing additional labor supply, incentivizing additional investments by firms, and incentivizing additional manufacturing capacity at home," CEA chair Stephen Miran told reporters Monday.

Reality check: Numbers of those magnitudes are a distinctly non-mainstream conclusion, even among analyses that do find some growth boost from the legislation.

• The Tax Foundation, a center-right think tank, finds that the version of the legislation that passed the House Ways and Means Committee last week would add 0.6% to long-run GDP.
• The Penn-Wharton Budget Model puts the gain at 0.5% over the next 10 years and 1.7% in 30 years.

Between the lines: A big difference between the White House economists' findings and those of other analysts is that the CEA analysis sees big supply-side gains from some of President Trump's campaign-trail tax promises not built into more mainstream models.

• "I want to emphasize that the segments of the labor force being targeted by some of those tax provisions, particularly no tax on overtime and no tax on tips, these are workers that are highly elastic and therefore highly responsive to changes in incentives," Miran said, which means the policies could help boost the economy's supply side.
