OMAHA, N.E.(WNAX)- While the latest survey of businesses in the nine state Mid America region indicated continued growth, there are also warning signs.

Creighton University economics professor Ernie Goss says inflation is a key indicator.

Goss says those factors could slow business activity.

Goss says long term interest rates may actually back down.

Goss coordinates the monthly survey of businesses from Minnesota and the Dakotas to Arkansas.
