"Business activity in Michigan accelerated impressively this summer, reflecting stronger national trends and a pick-up in auto sales and production," according to Dana Johnson, chief economist at Comerica Bank. "Compared to earlier in the year, the Michigan economy is in much better condition now to absorb the blow from rising energy prices and cutbacks in the Michigan based auto industry."

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.
