The document discusses adaptive pricing as a strategy for companies to increase sales without reducing prices. Adaptive pricing involves setting different prices for different customer segments based on their needs and willingness to pay.

The document provides examples of how companies in various industries like telecom, consumer goods, travel have implemented adaptive pricing strategies to weather economic downturns better than companies relying only on price discounts.
