переведите пожалуйста.WASHIGTON - Overall productivity feel in the second quarter, but continued to rise in manufacturing, revised government statistics showed.
The Labor Department said productivity, or output per hour of work, declined at a revised 2.5% annual rate in the nonfarm business sector in the second quarter. Previously, the department estimated that productivity dropped at 1.2% pace during the period. Productivity rose at 2.9% rate in the first quarter.

"I'm still encouraged by the overall trend,'' said Steven Roach, senior economist at Morgan Stanley and Co. He warned that quarterly productivity reports are volatile and sometimes unreliable. A decline in service-sector productivity accounted for the decline, but isn't separately calculated in the report.

A similar downward blip occurred in the first quarter of 1993, but was followed by a strong rebound in the second half of the year, he noted. Second -quarter productivity remains 2.3% above the 1993 second quarter. ''It's still an encouraging increase at this stage in the business-cycle expansion,'' he added.

The revised report also showed stronger signs of inflation than the previous estimate. Unit labor costs for nonfarm business rose at a 3.4% seasonally adjusted annual rate over the previous quarter; that originally had been reported as a 2% rate of increase. Year on year, however, unit labor costs are up just 0.7%. But factory wages don't appear to be under pressure: Unit labor costs in manufacturing fell at a 5.8% rate in the revised report, compared with a previously reported 5.2% rate of decline.

Productivity also continues to increase in manufacturing. The revised report showed a 4.5% rate of increase in manufacturing productivity, compared with a 3.8% rate of increase.

For the quarter, output grew at a 2.9% rate and a number of hours worked increased at a 5.8% pace. During the first quarter, output increased at a 5.5% rate, and hours worked rose at a 2.6% clip.
