Question

Consider the market for pens. Suppose that new research has been published stating that the process of writing, erasing, and rewriting improves memorization, leading parents to avoid giving their children pens in favor of pencils. Further, the price of plastic, 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.

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.
