Obama pushes stimulus but warns on recession

WASHINGTON (Reuters) - President-elect Barack Obama warned on Thursday that the U.S. economy could stay mired in recession for years without bold action and he urged lawmakers to work day and night to pass a massive stimulus plan.

Obama, who takes office on January 20, promised to set a new course for the economy and to quickly toughen the financial regulatory system.

But he gave few new details about the package of tax cuts and public-works spending likely to cost $800 billion (£526 billion) or more.

"I don't believe it's too late to change course, but it will be if we don't take dramatic action as soon as possible," Obama said in speech on the economy at George Mason University in Fairfax, Virginia.

"If nothing is done, this recession could linger for years. The unemployment rate could reach double digits."

Wall Street showed disappointment that Obama did not offer more specifics. The Dow Jones industrial average was down more than 1 percent in mid-afternoon trading, as the lack of new details added to other factors weighing on the market.

On the day Congress formally confirmed him as the winner of the November 4 election to take over from Republican President George W. Bush, Obama is about to inherit an economy that has been in recession for more than a year.

Obama is seeking approval by mid-February of the proposed stimulus package that he is crafting in close consultation with the Democratic-led Congress.
