Cost of corn does not dictate prices. However, the price of corn is a sort of barometer of prices in general.
Lets say I wanted to grow pigs. I could secure a futures contract for 100 finished hogs. Then, I would buy a futures contract for the corn and soy I need. Then I would figure my expenses and labor. From that I know how much I can pay for feeder pigs. If the price of finished hogs is high and the price of corn low, the price of feeder pigs is likely to be high. If hog futures are low and corn is high, feeder pigs will go cheap.
Before futures contracts, the commodity prices fluctuated wildly. Now businesses and farmers are somewhat protected from boom/bust pricing, through the purchase/sale of futures contracts.
