The shutdown has likely slowed growth in an already weak economy. Economists expect economic growth at an annual rate of between 1.5 percent and 2 percent from July through September. That would be down from a 2.5 percent annual rate in the April-June quarter.And economists expect little pickup in the October-December quarter. The shutdown likely cut a quarter- to a half-percentage point from growth in the final three months of the year.
