Question

Assume that there are four consumers (A, B, C, and D), each with their individual maximum willingness to pay for a product. Assume that there are four sellers (W, X, Y, and Z), each with a minimum price at which they are willing to sell. These reservation prices are given in Table 2 below. Assume that each seller has one unit to sell and each buyer only wants to buy one unit.

Consumers                               Willingness to Pay

A                                                          $120

B                                                          $110

C                                                         $95

D                                                         $80

Sellers                                      Willingness to Sell

W                                                         $70

X                                                          $85

Y                                                          $95

Z                                                          $115

Table 2: Reservation Prices of Four Buyers and Four Sellers

2(a). If the price in the market was $95, which consumers would buy? How much surplus would each consumer get?

2(b). If the price in the market was $95, which sellers would be willing to sell? How much surplus would each seller get?

2(c). If the price in the market was $100, would the total surplus be greater than when the price was $95?

2(d). If you could match buyers and sellers in order to maximize the number of units ex-changed, then buyers and sellers should be matched? What would be the total surplus resulting from these matches?

Explanation / Answer

2(a). If the price in the market was $95, consumer C, B and A would buy it. How much surplus would each consumer get. C will get $0, B will get $15, and A will get $25.

2(b). If the price in the market was $95, sellers W, X and Y are willing to sell. Surplus -- W will get $25, X will get $10 and Y will get $0.

2(c) Yes

2(d) $40 would be the total surplus.
