Tax cuts are going to grow the economy by much more than expected.

That’s the verdict of the Wall Street Journal‘s prestigious “Heard on the Street” column. Importantly, Heard on the Street is run by the news side of the WSJ, not its tax-cut loving editorial page. So there’s no particular pro-tax cut or pro-Republican bias at work here.

Justin Lahart of Heard writes:

There were several surprises for investors when Republicans unveiled their final tax bill Friday, but the most significant is that they add up to a bigger boost to economic growth next year. The bigger stimulus could fundamentally change how the market behaves in 2018. Sales and profits will be stronger than most investors expect. But with the unemployment rate low, wage pressures will mount faster, and inflation should pick up more. If the tax plan passes, as seems likely, it could lead the Federal Reserve to raise rates faster, putting the bond market at risk.
