Suppose that Yakov and Ana are the only consumers of shoes in a particular market. The following table shows their annual demand schedules:
Price |
Yakov's Quantity Demanded |
Ana's Quantity Demanded |
---|---|---|
(Dollars per pair) |
(Pairs) |
(Pairs) |
10 | 32 | 56 |
20 | 20 | 40 |
30 | 12 | 24 |
40 | 4 | 12 |
50 | 0 | 4 |
On the following graph, plot Yakov's demand for shoes using the green points (triangle symbol). Next, plot Ana's demand for shoes using the purple points (diamond symbol). Finally, plot the market demand for shoes using the blue points (circle symbol).

Now, suppose that Ana's twin brother, who likes shoes just as much a Ana, moves to the area, adding another consumer in the market. As a result, there will be a the market demand curve because there will be a change in quantity demanded .
Correct Answer:
Rightward movement in the market demand curve
Since at each price level, the market demand increases, then there will be rightward shift in the market demand curve.
