The top risk to U.S. growth would come if U.S. President-elect Donald Trump keeps his protectionist promises, according to a Reuters poll that shows economists have not joined in the market exuberance since the shock November vote.
For most of his campaign and after the election, Trump vowed to make sweeping changes to U.S. trade and immigration policy, threatened to impose steep tariffs on Chinese imports and proposed hefty tax cuts.
While financial markets have retreated in the past week and hopes of a sudden spurt in inflation have faded, U.S. 10-year Treasury yields are still up more than 25 percent since Election Day, and stocks have hit record highs.

Still,more than two-thirds of the 70 respondents to the question in the Reuters survey taken over the past week said Trump's protectionist policies were the biggest threat to the world's largest economy this year.
"There is no question that near the top of the list of downside risks is the potential for more follow-through on the anti-free trade rhetoric," said Jim O'Sullivan of High Frequency Economics.
"I am kind of assuming that the (incoming) administration will be practical on this," said O'Sullivan, the top forecaster of U.S. economic data in Reuters polls for 2016, the second year in a row he achieved that distinction.
The strong dollar, which hit a 14-year high early this month and is up close to 6 percent since Trump was elected, poses an additional near-term risk.
Worries around the globe over Trump's confrontational style and a strengthening dollar are likely to be key themes among political and business leaders at the World Economic Forum in Davos, Switzerland, this week.
Sweeping tax cuts for businesses and individuals, and the prospect of some infrastructure spending, have also not brightened prospects for U.S. economic growth, which Trump has said he aimed to boost to 3.5 percent.
More than 80 percent of respondents said "no" when asked if now was the right time for such aggressive tax cuts, with the economy close to full employment. The unemployment rate was 4.7 percent in December.
The latest poll estimated growth slowed to 2.2 percent in the fourth quarter from 3.5 percent in the third quarter.
Through 2017, economists predicted the economy would expand at an annual rate of 2.1 percent to 2.5 percent each quarter, just 0.1 percentage point higher than the previous estimate. The full-year median was 2.3 percent.
The most optimistic growth forecast for any point in 2017 was 4.1 percent, far short of the post-financial crisis peak of 5.6 percent hit in the fourth quarter of 2009.
"Obviously people have been assuming the growth-sapping parts (protectionist measures) are not followed through, but they may have run ahead of themselves in predicting how much stimulus will be enacted and how much growth will be boosted," said O'Sullivan, who was also the most optimistic on growth among the top forecasters.
A little fewer than one-third of the respondents, including three of the top 10 U.S. economy forecasters in Reuters polls last year, upgraded their 2017 growth outlooks in the latest poll.
Many of them, like O'Sullivan, said it was mainly on the assumption Trump would not follow through on his restrictive trade agenda and instead focus on boosting growth through fiscal measures.
While those projected growth rates may be considered healthy for the economy at such a late stage of the recovery cycle, they could do little to boost inflation much beyond the Federal Reserve's 2 percent target.
Inflation pressure is more likely to come from a round of retaliatory tariffs if Trump's protectionist agenda becomes a global reality.
Even though pay growth is forecast to average 3.0 percent this year, up from 2.8 percent in December's poll, the Fed's preferred gauge of inflation, the Core PCE Price Index, will probably average 1.8 percent in 2017 and 2.0 percent in 2018, unchanged from the last poll.
Fed policymakers recently warned that with the economy close to full employment, an expansive fiscal policy could lead to faster rate hikes than currently priced in, pushing the U.S. dollar higher.
"If the unemployment rate falls some more, it is going to add to upward pressure on wages and inflation and reinforce the case for Fed tightening," O'Sullivan said.
The wider poll of over 100 economists, including 17 large banks that transact directly with the Fed, showed rates would remain unchanged at 0.50 percent to 0.75 percent until the second quarter, when a 25-basis-point hike is likely.
A follow-up increase is expected in the fourth quarter, taking the Fed funds rate to a range of 1.00 percent to 1.25 percent. Fourteen economists, however, forecast a hike by March.
