Price of gasoline up.
Oil refineries at reduced capacity
Oil executives explain that they are reducing capacity because there is an over-supply of gasoline.
Congress seeks ways to provide easier oil & gas exploration because oil executives have said that there is a shortage of supply.

when there is too much supply, price goes up.
when there is too much demand, price goes up.
when there is overstock of gasoline, the price goes up.

If you can spot the pattern, you are an economist. If you can plot the pattern you are an econometrician. If you can create the Plot, then you are an Oil Executive.
