Importance of marginal cost in price discrimination 价格歧视中边际成本的重要性
In markets where the marginal cost of an extra passenger is very low, the firm has an incentive to use price discrimination to sell all the tickets. This is why sometimes prices for airlines can be very low just before their date. Once the company is due to fly the MC of an extra passenger will be very low. Therefore this justifies selling the remaining tickets at a low price. 在多一个乘客的边际成本很低的市场，公司有动力使用价格歧视来销售所有的机票。这就是为什么有时航空公司的价格在其日期前会非常低。一旦公司的航班到期，额外乘客的MC将非常低。因此，这就证明了以低价出售剩余机票的合理性。
