A drought in Alberta and Saskatchewan has made grain, and therefore cattle feed, quite expensive. Many ranchers cannot afford to feed their cattle, and have sold much of their herd for slaughter. As it happens, the slaughter of beef cattle has coincided with a decrease in consumer incomes. Assuming that steak is a normal good while hamburgers are an inferior good, use a supply-and-demand diagram for both the steak and hamburger markets to illustrate the effect of these two aforementioned events on the equilibrium price and quantity of hamburgers and then steak?
