Economic impact estimates are all over the map when it comes to how much of an affect President-elect Donald Trump’s 10-year $1 trillion infrastructure proposal will have on the economy. To that end, two reports came out this week that come to completely different conclusions.

The first, by Georgetown University, says that Trump's plan could create as many as 11 million jobs. However, it cautions, the additional spending in combination with proposed tax cuts and other economic policy shifts could “overheat the economy” by increasing inflation and setting the stage for further interest rate hikes.

The Tax Foundation had a much more modest take. This is partly because the report assessed the varying degrees of economic impact the proposal would have depending on what other policy measures are implemented. The foundation looked at the impact of a theoretical $500 billion investment by the federal government through five funding mechanisms: borrowing, cutting government spending, raising excise taxes, raising the top tax rate on individual income and raising the corporate income tax.
