“Ms. Romer argued last year that this “multiplier” for government meant every dollar spent created about $1.50 worth of demand.
Some economists say that’s too high. Valerie Ramey of the University of California at San Diego, initially thinking as a Keynesian, developed doubts after sifting through historical examples. During the military build-ups of World War II, the Korean War and the Reagan era, a dollar spent added roughly a dollar of growth, she says. Although Ms. Ramey supported stimulus in 2009 because the economy was so weak, she doesn’t advocate more now. “We just don’t have enough evidence to prove that it’s good.”
Robert Barro, a Harvard economist, found even smaller multipliers: A government dollar spent creates about 80 cents worth of growth, or possibly less, he says. Government spending, he says, crowds out private sector spending that would otherwise be taking place.”
