DETROIT, Jan. 13 /PRNewswire-FirstCall/ -- The Advance Economic Barometer (AEB), Comerica's predictive index for the State of Michigan economy, registered 2.8 points in December, down 0.4 points from November, and below the year-earlier level of 4.9, said David Littmann, chief economist for Detroit-based Comerica Bank.

The AEB reading suggests Michigan's Gross State Product is rising but at a decelerating pace, Littmann said.

Comerica's Michigan Business Activity Index (MBAI), a proxy for changes in statewide disposable personal income, depicts current movements in Michigan's real economy. In November the MBAI gained 1 point and now stands at 113, versus 111 in November 2003.

Comerica Bank, Michigan's oldest and largest bank, is the lead subsidiary of Comerica Incorporated (NYSE:CMA) , a multi-state financial services provider headquartered in Detroit.
