How behavioral economics is being used in marketing

McKinsey Quarterly:

1. Make a product’s cost less painful

[...]Retailers know that allowing consumers to delay payment can dramatically increase their willingness to buy. One reason delayed payments work is perfectly logical: the time value of money makes future payments less costly than immediate ones. But there is a second, less rational basis for this phenomenon. Payments, like all losses, are viscerally unpleasant. But emotions experienced in the present—now—are especially important. Even small delays in payment can soften the immediate sting of parting with your money and remove an important barrier to purchase.

Another way to minimize the pain of payment is to understand the ways “mental accounting” affects decision making. Consumers use different mental accounts for money they obtain from different sources rather than treating every dollar they own equally, as economists believe they do, or should.

[...]Technology creates new frontiers for harnessing mental accounting to benefit both consumers and marketers. (Think Farmland or Sims, taking money from there into the real world or vice versa)

[...]2. Harness the power of a default option

The evidence is overwhelming that presenting one option as a default increases the chance it will be chosen. Defaults—what you get if you don’t actively make a choice—work partly by instilling a perception of ownership before any purchase takes place, because the pleasure we derive from gains is less intense than the pain from equivalent losses. When we’re “given” something by default, it becomes more valued than it would have been otherwise—and we are more loath to part with it.

Savvy marketers can harness these principles. An Italian telecom company, for example, increased the acceptance rate of an offer made to customers when they called to cancel their service. Originally, a script informed them that they would receive 100 free calls if they kept their plan. The script was reworded to say, “We have already credited your account with 100 calls—how could you use those?” Many customers did not want to give up free talk time they felt they already owned.

Defaults work best when decision makers are too indifferent, confused, or conflicted to consider their options.

[...]3. Don’t overwhelm consumers with choice

When a default option isn’t possible, marketers must be wary of generating “choice overload,” which makes consumers less likely to purchase. In a classic field experiment, some grocery store shoppers were offered the chance to taste a selection of 24 jams, while others were offered only 6. The greater variety drew more shoppers to sample the jams, but few made a purchase. By contrast, although fewer consumers stopped to taste the 6 jams on offer, sales from this group were more than five times higher.

[...]4. Position your preferred option carefully

[...]Consider the experience of the jewelry store owner whose consignment of turquoise jewelry wasn’t selling. Displaying it more prominently didn’t achieve anything, nor did increased efforts by her sales staff. Exasperated, she gave her sales manager instructions to mark the lot down “x½” and departed on a buying trip. On her return, she found that the manager misread the note and had mistakenly doubled the price of the items—and sold the lot. In this case, shoppers almost certainly didn’t base their purchases on an absolute maximum price. Instead, they made inferences from the price about the jewelry’s quality, which generated a context-specific willingness to pay.

[...]Our research suggests, for instance, that ice cream shoppers in grocery stores look at the brand first, flavor second, and price last. Organizing supermarket aisles according to way consumers prefer to buy specific products makes customers both happier and less likely to base their purchase decisions on price—allowing retailers to sell higher-priced, higher-margin products. (This explains why aisles are rarely organized by price.) For thermostats, by contrast, people generally start with price, then function, and finally brand. The merchandise layout should therefore be quite different.
