4. Consumer surplus for an individual and a market The following graph shows Jacques's weekly demand for apple pie, represented by the blue line. Point A represents a point along his weekly demand curve. The market price of apple pie is $3.00 per slice, as shown by the horizontal black line. Jacques's Weekly Demand 7.50 6.75 6.00 5.25 Demand 4.50 Y-Intercept: 3 3.75 Price 3.00 225 1.50 0.75 10 12 14 16 18 20 QUANTITY (Slices of apple pie) From the previous graph, you can tell that Jacques is willing to pay s for his 8th slice of apple pie each week. Because he has to pay only $3.00 per slice, the consumer surplus he gains from the 8th slice of apple pie is s PRICE (Dollars per slice) Suppose the price of apple pie were to fall to $2.25 per slice. At this lower price, Jacques would receive a consumer surplus of $ from the 8th slice of apple pie he buys. The following graph shows the weekly market demand for apple pie in a small economy. Use the purple point (diamond symbol) to shade the area representing consumer surplus when the price (P) of apple pie is $3.00 per slice. Then, use the green point (triangle symbol) to shade the area representing additional consumer surplus when the price falls to $2.25 per slice. Small Economy's Weekly Demand 7.50 6.75 Initial Consumer Surplus (P = $3.00) 6.00 5.25 Demand 4.50 Additional Consumer Surplus (P = $2.25) 3.75 P= $3.00 3.00 2.25 P = $2.25 1.50 0.75 20 40 60 100 120 140 160 180 200 QUANTITY (Thousands of slices of apple pie) PRICE (Dollars per slice)
