Business communication students may learn about Robert Cialdini’s Six Principles of Persuasion, including scarcity. For example, a online retailer indicates “Only two left!” or “Only one left at this price!”

In a Wall Street Journal article, a researcher questions whether the “quantity scarcity” strategy works under all conditions. Dr. Christopher Tang explains new research:

“…scarcity messages work best with time-sensitive and perishable products such as hotel rooms or plane tickets, as well as unique items like collectibles or limited editions.

“They are less effective with durable goods such as home-improvement products or kitchenware, in part because they can give shoppers the impression that the product is being pushed because it is undesirable, lower quality, obsolete or discontinued. And in the case of items typically bought in larger quantities, such as partyware, lightbulbs and batteries, we found that scarcity messages can actually hurt sales by making shoppers believe they won’t be able to buy as much of a product as they want.”

To use the scarcity principle effectively, Dr. Tang suggests that retailers highlight quality, promote urgency, and offer product bundles

Discussion:

• When have you seen the quantity scarcity at work? Did it persuade you to purchase something?

• Think of a specific product that you might buy. How would you recommend that retailers use this strategy effectively to move remaining products?
