The U.S. Labor Department released its final non-farm productivity figures on Tuesday. Final productivity in the U.S. non-farm businesses declined at a 0.6% annual rate in the first quarter, up from the preliminary reading a 1.0% drop, after a 1.7% decrease in the fourth quarter.

The upward revision was driven by higher nonfarm business output, which rose 0.9% in the first quarter, up from the preliminary reading of a 0.4% gain.

Hours worked increased by 1.5% in the first quarter, in line with the preliminary reading.

Final unit labour costs climbed 4.5% in the first quarter, up from the preliminary reading of a 4.1% increase, after a 2.7 gain in the fourth quarter.
