"The regional economy appeared to be at a stand still at year end," according to Dana Johnson, chief economist at Comerica Bank. "A mild upswing this summer was halted by cuts in the auto sector, elevated energy prices, and rising short-term interest rates. The Super Bowl should be a great event for Detroit, but it won't prevent the local economy from continuing to lag in 2006."
