Harmattan and Ice Cream. Suppose an unusually long harmattan (dry wind) decreases cocoa yields, increasing the cost of producing chocolate ice cream by 10 percent. Use a supply–demand graph to show the implications for the equilibrium price of chocolate ice cream. (Related to Application 5 on page 113.)
