Will the equilibrium price of orange juice increase or decrease in each of the following situations? LO7a.
A medical study reporting that orange juice reduces cancer is released at the same time that a freak storm destroys half of the orange crop in Florida.
The prices of all beverages except orange juice fall in half while unexpectedly perfect weather in Florida results in an orange crop that is 20 percent larger than normal.
3. Suppose that annual demand in the U.S. market for ice cream cones can be expressed as QD = 800 + .2I - 100P,
where QD is the number of cones demanded in millions of cones, I equals average monthly income in dollars, and P is price in dollars per cone.
Supply can be expressed as QS = 200 + 150P (with the same units for quantity and price).
A. Graph the demand and supply curves for ice cream cones, assuming that average monthly income is $2,000, and solve for the equilibrium price and quantity.
B. Now assume that average monthly income drops to $750 and supply is unchanged.
Draw the new demand curve on the same graph as used in (a) above and solve for the new equilibrium price and quantity.
How would you describe the shift in demand intuitively
For the first time in two years, Big G (the cereal division of General Mills) raisedcereal prices by 4 percent. If, as a result of this price increase, the volume of all cerealsold by Big G dropped by 5 percent, what can you infer about the own price elasticityof demand for Big G cereal? Can you predict whether revenues on sales of its LuckyCharms brand increased or decreased? Explain. (LO1, LO3)
