The U.S. economy will grow faster in 2012 - if it isn't knocked off track by upheavals in Europe, according to an Associated Press survey of leading economists.
Unemployment will barely fall from the current 8.6 percent rate, though, by the time President Obama runs for re-election in November, the economists say.
The three-dozen private, corporate and academic economists expect the economy to grow 2.4 percent next year. In 2011, it likely grew less than 2 percent.
The year is ending on an upswing. The economy has generated at least 100,000 new jobs for five months in a row - the longest such streak since 2006.
The number of people applying for unemployment benefits has dropped to the lowest level since April 2008. The trend suggests that layoffs have all but stopped and hiring could pick up.
And the economy avoided a setback when President Obama signed legislation Friday extending a Social Security tax cut that was to expire at year's end. But Congress could agree on only a two-month extension.
The economists surveyed Dec. 14-20 expect the country to create 177,000 jobs a month through Election Day 2012. That would be up from an average 132,000 jobs a month so far in 2011.
Dean Maki, chief U.S. economist at Barclays Capital, said that the U.S. economy remains vulnerable to an outside shock. A big threat is the risk that Europe's debt crisis will trigger a worldwide credit freeze, like the one that hit Wall Street in late 2008.
A shock to the U.S. economy, he said, might not be as dangerous if it were growing at a healthier 4 percent to 5 percent annual pace. But when growth is stuck at 2 percent or 3 percent, a major global crisis could stall job creation and raise unemployment.
Beyond Europe, Congressional gridlock ahead of the 2012 elections and unforeseen global events, like this year's Arab Spring protests, could slow the U.S. economy. Three economists said that rising nuclear tensions with Iran are a concern.
Even without an outside jolt, the economists expect barely enough job creation in 2012 to stay ahead of population growth and the return of discouraged workers into the labor force.
A majority (56 percent) of the economists said that the economy will get a lift from Federal Reserve policies. The Fed has said that it plans to keep short-term interest rates near zero through at least mid-2013 if the economy remains weak. The central bank also has begun a campaign to try to push down mortgage rates and other long-term interest rates through next June.
Those surveyed also think that the economy is strong enough to withstand higher oil prices. At near $100 a barrel, oil prices are up 10 percent from a year ago.
The economists expect the European economy to shrink 0.5 percent in 2011 - and fall into a recession. Europe is slowing as heavily indebted countries slash spending and banks exposed to government debt curtain lending.
Among the gravest fears is that a major country like Italy will default on its debt, wiping out some banks with large holdings of European government bonds. A worldwide credit crunch like the one that followed the 2008 failure of Lehman Bros could follow.
If Europe can stabilize its economies, the U.S. stock markets would rally sharply, economists said, and prospects for U.S. economic growth would brighten.
