WASHINGTON: The US GDP is on track to grow by more than 6 percent this year, owing in part to its fiscal policy, according to a report. The revelation was made in the Peterson Institute for International Economics (PIIE)'s semi-annual Global Economic Prospects released on Thursday, Xinhua news agency reported. "Of the large advanced economies, the US will expand the fastest in 2021, owing in part to its aggressive fiscal policy response," said PIIE Senior Fellow Karen Dynan, who is also former chief economist at the Treasury Department.
