Whatever that stat actually means...From AP:
Worker productivity rose by a better-than-expected amount in the first three months of the year while labor cost pressures eased. ...The Labor Department reported Wednesday that productivity, the amount of output per hour of work, increased at an annual rate of 2.2 percent in the first quarter. That was slightly higher than the 1.5 percent increase which had been expected. ...In a sign that inflation could be easing, labor cost pressures slowed a bit. Unit labor costs rose at an annual rate of 2.2 percent, down from a 2.8 percent rise in the final three months of last year. ...While rising wages and benefits are good for employees, those increases can lead to higher inflation if businesses are forced forced to boost the cost of their products to cover the higher payroll costs....However, if productivity is increasing it allows businesses to finance higher wages out of the increased output. ...The Federal Reserve, which is always on guard about the threat of inflation, closely monitors developments in productivity since wage pressures are often the key way that inflation gets out of control.
