I have long been making the point that the simple behavioral experiments performed by the new breed of economists are daily producing more useful insights for marketers than the millions we spend on fatuous and self-serving research.
Here is a new and brilliant test mentioned in the blog of Libertarian Economist Tyler Cowen at George Mason University. Interestingly it does much to support Drayton Bird, Russell Davies and the Sales Promotion industry. Among others.
Drayton bird once told us that, after years working on a tourist account, his only useful finding was that heading the coupon with "free brochure" invariably increased response; he taught us that "free" and "new" were the two most compelling words in any advertisement. Russell Davies last week wrote on the immense power of Free and Pretty Good in the world of content. Sales Promotion has long argued that giving free stuff away with a product does not have the same devaluing effect as discounting.
Now there comes an intersting experiement performed by Dan Ariely, author of Predictably Irrational: The Hidden Forces which shape our Decisions.
Details of the experiment appear here. Non-US readers should know that a Kiss is a Hershey's Kiss (not a physical one), a low-priced chocolate drop.
Those who believe the change in behaviour between cheap and free are attributable to transactional costs (the hassle of getting a coin from your pocket) are wrong - in that the experiment only offered the choice to people who were already queuing to pay for other items.
The fact that we perceive free things in an altogether different way to cheap things is highly significant. It justifies the wholly-advertising-funded model for content. It explains Drayton's findings. And it suggests that freebie-on is not the same as money off.
Incidentally, I happily predict that the two books Sway: The Irresistible Pull of Irrational Behavior, by Ori and Rom Brafman and Nudge: Improving Decisions About Health, Wealth and Happiness (this being a defence of the idea of voluntary paternailsm) by Richard Thaler and Cass Sunstein may be the Freakonomics of 2008. Preorder them now.
