4) Corn has many uses: it is eaten fresh or used as a processed component of many foods; it is fed to animals; it is a widely used sweetener (corn syrup); and it is converted into ethanol and used as fuel. Between July 2012 and July 2019, corn prices declined by more than 50%, dropping from $8.10 per bushel to $4.00 per bushel. Suppose you have been invited to speak as an economics expert on a local podcast. The host of the podcast asks you about the effect of relatively low corn prices on the following two markets: (1) grocery store prices of cornfed beef; and (2) grocery store prices of grass-fed beef. Explain and use supply-demand graphs to show the effects in each market. Include any assumptions you may make, and create a separate graph for each market.
