An increase in housing starts helped to push the University of Oregon Economic Index forward.  Tim Duy, Director of the Oregon Economic Forum, two up months in a row is a good sign.  Duy says it's not a huge increase, but it's growth. Duy says all signs appear to show that Oregon's economy will continue to grow in 2011 maybe a little better than expected.  But he cautions that the construction industry still has some significant challenges.
