[1] If the demand for corn increases due to its use as an alternative energy source, what will happen to the supply of corn's substitute such as soybean? Assume that, besides being substitutes for one another, corn and soybeans require the same raw material, such as the same farm land. Think about whether farmers will use their soybean farms to produce more or less corn. Explain, in economic terms [e.g. supply determinants], why this is so. [2] What will happen to the price of corn oil? [3] How does the price elasticity of demand for corn oil influence the quantity-demanded of corn oil and the Total Revenue earned by sellers of corn oil? Explain, using economic terms, why this is so.
