But some are growing more concerned that the economy’s weakness will persist. The Fed said Wednesday that its survey of economic activity found growth slowed in eight of its 12 regions in June and early July. The report, known as the Beige Book, was the weakest this year.

Many economists are becoming more pessimistic about the second half of this year. Goldman Sachs recently cut its estimate for growth in the July-September period to 2.5 percent, down from 3.25 percent. JPMorgan, meanwhile, reduced its estimate to 2.5 percent from 3 percent.

Growth of about 2.5 percent is barely enough to reduce the unemployment rate. The economy would need to grow 5 percent for a whole year to bring down the rate by one percentage point.
