Though Obama aides declined to discuss a total cost, it probably would far exceed the $175 billion he proposed during the campaign, but would not immediately seek to raise taxes on the rich. Some economists and lawmakers have argued for a two-year plan as large as $700 billion, equal to the Wall Street bailout Congress approved last month.
With the wounded economy worsening, the Obama team's new assertiveness was a recognition he needed to soothe financial markets with signs of leadership. It also foreshadowed a more hands-on role by Obama to influence congressional action during the final weeks of the transition.
Obama planned to introduce his economic team on Monday, including Timothy Geithner as treasury secretary and Lawrence Summers as head of the National Economic Council. Obama also has settled on New Mexico Gov. bill Richardson as his commerce secretary.
"We don't have time to waste here, " Obama senior adviser David Axelrod said. "We want to hit the ground running on January 20th." Echoing that, theeshed out.
Obama could delay any tax increase to 2011, when current Bush administration tax cuts expire.
House Republican leader John Boehner of Ohio urged Obama to make that explicit. "Why wouldn't we have the president-elect say, `I am not going to raise taxes on any American in my first two years in office?"' In a sign of where the congressional debate might lead, Boehner called for lowering capital gains and corporate income taxes.
Some economists have endorsed spending up to $600 billion to revive the economy. Sen. Charles Schumer, D-N.Y., and former labor Secretary Robert Reich, a member of Obama's economic advisory board, both suggested $500 billion to $700 billion.
"I don't know what the number is going to be, but it's going to be a big number," Goolsbee said. "It has to be. The point is to, kind of, get people back on track and startle the thing into submission."
While Obama in the weekend Democratic radio address said his plan "will mean 2.5 million more jobs by January of 2011," aides said the figure was a net sum of jobs created and jobs saved that would otherwise disappear without government help.
The adviser who spoke on condition of anonymity said the plan would likely slow down job losses in 2009, but that new jobs probably would not be evident until 2010.
Obama's plan is both an economic and a political blueprint. By not including tax increases, he silences one potential Republican objection to his plan. If successful, the scope of his plan would set the stage for his other legislative goals, including expanded health care, permanent changes in tax rates and a comprehensive overhaul of energy policy.
"This package is designed to be a down payment to get his entire agenda started," the aide said.
