It was nice while it lasted - gas prices down below $2 a gallon. These days, prices are headed back up, though only slightly above $2.

Dr. Matthew Ross, Western Michigan University assistant professor of finance and commercial law and a former oil industry engineer, tells The Richard Piet Show there are definite winners and losers when oil is cheap.
