"When Trump came up with this infrastructure spending (plan), you notice that both Janet Yellen and Stanley Fischer came out and welcomed that as the real pillar supporting the U.S. economy," Richard Koo said as he joined CNBC from Lake Como, Italy, at the Ambrosetti Forum.
Fischer, vice chairman of the Federal Reserve proclaimed shortly after Trump's surprise election victory in November that boosting spending on infrastructure could shoulder some of the burden away from the U.S. central bank to support the economy.
Meanwhile, Fed Chair Janet Yellen said in February she would be watching carefully to see how Trump's campaign pledges impacted American workers.
The U.S. president is seeking approval from Congress for a $1 trillion infrastructure bill in an attempt to reinvigorate the U.S. economy.
However, Trump's surprise failure to bring about swift health-care reforms left many observers in doubt as to whether he can deliver on his other campaign pledges, such as his plans to upgrade America's roads, airports and rail lines.
"In that sense what Trump is trying to do, by government borrowing and spending the money is a positive thing for the U.S. economy … But whether he will get that or not in the Republican-controlled Congress is, of course, a big if," Koo concluded.
