"With national growth slowing and American auto companies slashing production and payrolls, Michigan is still caught in a one state recession," said Dana Johnson, Chief Economist at Comerica Bank. "The state should start doing better by the second half of next year, reflecting a reacceleration of national growth and a slower pace of restructuring in the auto sector."

The Michigan Business Activity Index (MBAI) represents ten different measures of Michigan economic activity compiled monthly by the Economics Department of Comerica Bank. The MBAI is seasonally adjusted, corrected for inflation, and expressed as an index, with 1996 as base year equal to 100. The MBAI series has been calculated monthly since 1957 and depicts state economic activity over seven full swings of the U.S. business cycle.
