The latest evidence comes as the government reports that employers paid the biggest wage increases in a year, rising .4% last month, twice economists’ expectations. Employers also created more jobs as payrolls grew by 207,000 last month, the biggest increase in three months. Still, theU.S.unemployment rate held steady at 5% as more workers entered the labor force in search of jobs. The civilian labor force increased by 450,000 in July, the Labor Department said. Of those, 438,000 found jobs.
