Document Summary
Consumer surplus: the buyer"s willingness to pay for a good minus the amount the buyer actually pays for it. The market demand curve depicts various quantities that buyers would be willing and able to purchase at different prices. The cs can be illustrated as the area under the demand curve above the selling price line. Producer surplus: the amount a seller is paid for a good minus the seller"s cost. It measures the benefit to sellers participating in a market. Cost is a measure of the seller"s willingness-to-sell, which is the lowest price a supplier will take to produce a good and offer it for sale. When a producer receives more than they are willing to take to produce a good, they enjoy a benefit. Cs = value to buyer amount buyer pays. Ps = amount sellers receive cost to sellers. Since amount buyer pays = amount sellers receive. Total surplus = consumer surplus + producer surplus.
