"With the Michigan economy less dependent on the auto sector than it was in the past, the weakness in the national economy is not having a devastating impact on the state economy," said Dana Johnson, Chief economist at Comerica Bank. "To be sure, activity in Michigan is slowing in early 2008, but in a manner that roughly parallels the slowdown in the national economy."
