Oregon’s economy is showing more signs of growth. Tim Duy, a professor of Economics at the University of Oregon, says his latest economic index for the state shows improvement, but he has concerns. Duy says there was more hiring of temporary workers in November and manufacturing is starting to grow. He says the economy would really need to heat up for inflation to be a worry. He expects growth will be slow in 2011 and it should start making significant gains in 2012.
