The US Labor Department said that labor productivity climbed by 1.5 per cent in the Q2 compared to the previously reported 0.9 per cent increase.

With the upward revision, the productivity growth in the second quarter reflects an even more substantial acceleration from the 0.1 percent uptick seen in the first quarter.

The bigger than previously estimated increase in productivity, a measure of output per hour, came as output spiked by more than initially estimated.
