WASHINGTON  As part of his emerging program to jolt the economic recovery from its stall, President Obama will call this week for allowing businesses to deduct from their taxes through 2011 the full value of new equipment purchase, from computers to utility generators, to increase demand for goods and create jobs.

The upfront deduction would allow businesses of all sizes to keep more money now and would give large corporations, many of which are sitting on cash because of uncertainty about the economy, an incentive to spend and invest.

It would cost an estimated $200 billion in revenues, though the ultimate net loss would be $30 billion over 10 years, administration officials say, since businesses would eventually deduct the depreciated value of the equipment in any case.

The proposal for 100 percent expensing through 2011 will be part of a package that Mr. Obama will outline on Wednesday in Cleveland in a speech on the economy.
