Price skimming

is a pricing strategy in which a marketer sets a relatively high price for a product or service at first, then lowers the price over time. It is a temporal version of price discrimination/yield management. It allows the firm to recover its sunk costs quickly before competition steps in and lowers the market price.

Price skimming is sometimes referred to as riding down the demand curve. The objective of a price skimming strategy is to capture the consumer surplus. If this is done successfully, then theoretically no customer will pay less for the product than the maximum they are willing to pay. In practice, it is almost impossible for a firm to capture all of this surplus.
