There are 4 consumers in the market for sweaters. Consumer 1 is willing to spend \pounds 40 on a sweater, Consumer 2 is willing to spend \pounds 35, Consumer 3 is willing to spend \pounds 25, and Consumer 4 is willing to spend \pounds 20. Each consumer only wants to buy one sweater. If the market price for sweaters is \pounds 28, what is the total consumer surplus in this market?
Consumer 1: Surplus = \pounds 40 − \pounds 28 = \pounds12 ; Consumer 2: Surplus = \pounds 35 − \pounds 28 = \pounds 7. Consumers 3 and 4 will not get any surplus because they will not buy. Total consumer surplus = \pounds 12 + \pounds 7 + \pounds 0 + \pounds 0 = \pounds 19.
