Robert Samuelson told readers that: "the CBO estimated that nearly 30 percent of the economic effects would occur after 2010." Actually, this refers to fiscal year 2010, which ends on September 30, 2010. If we assume that spending in the fourth quarter of 2010 continues at the same rate as during the fiscal year, then only about 15 percent of the impact of the stimulus would be felt after 2010.
