Consider the market for pens. Suppose that the number of students who are allergic to the rubber used in pencil erasers increases, leading more students to switch from pencils to pens in school. Further, the price of ink, a major input in the pen production process, has dropped sharply. On the following graph, labeled Scenario 1, indicate the effect these two events have on the demand for and supply of pens Note: Select and drag one or both of the curves to the desired position. Curves will snap into position, so if you try to move a curve and it snaps back to its original position, just drag it a little farther Benario 1 Equilibrium Object Price Quantity Ⓒ True Supply QUANTITY (Mons of pens) Boenario 2 O False Demand Next, complete the following graph, labeled Scenario 2, by shifting the supply and demand curves in the same way that you did on the Scenario 1 graph Supply Scenario 1 bemand QUANTITY (Mons of pens) 10 Demand . 10 Supply Demand Compare both the Scenario 1 and Scenario 2 graphs. Notice that after completing both graphs, you can now see a difference between them that wasn't apparent before the shifts because each graph indicates different magnitudes for the supply and demand shifts in the market for pens. - Use the results of your answers on both the Scenario 1 and Scenario 2 graphs to complete the following table. Begin by indicating the overall change in the equilibrium price and quantity after the shift in demand or supply for each shift-magnitude scenario. Then, in the final column, indicate the resulting change in the equilibrium price and quantity when supply and demand shift in the direction you previously indicated on both graphs. If you cannot determine the answer without knowing the magnitude of the shifts, choose Cannot determine. (?) Supply Change in Equilibrium Objects Scenario 2 True or False: When both the demand and supply curves shift, the curve that shifts by the smaller magnitude determines the effect on the undetermined equilibrium object. When Shift Magnitudes Are Unknown
