Consider the market for pens. Suppose that the number of students with an allergy to pencil erasers increases, causing more students to switch from
pencils to pens in school. Moreover, the price of plastic, an important input in pen production, has dropped considerably.
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.

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.
Equilibrium Object
Price
Quantity
True
Scenario 1
O False
Change in Equilibrium Objects
Scenario 2
True or False: When both the demand and supply curves shift, the curve that shifts by the larger magnitude determines the effect on the
undetermined equilibrium object.
