How Do You Keep the Public Shopping? Just Make People Sad shares some fascinating studies in behavioral economics:

Some behavioral economists are now turning to the role of emotions, too, investigating how heart strings affect purse strings. Last year, researchers found that anger makes people assess situations more optimistically, downplaying risks and overestimating potential benefits (which may explain why one chronically grouchy investor I know loads up on junk bonds and is low on cash). Fear does the opposite, making us exaggerate risks and minimize benefits. In fearful times, more people gravitate toward bank CDs.

To see how two negative emotions, disgust and sadness, affect economic decision making, Prof. Lerner and her colleagues recruited 199 volunteers, age 16 to 49. Some watched a scene from the 1979 tearjerker “The Champ,” in which a boy’s father dies. Others watched the infamous filthy-toilet clip from the 1996 Gen-X hit “Trainspotting.” A third group watched an emotionally neutral clip of coral reef fish. All wrote down how they felt afterward.

Half the volunteers, drawn equally from the three film audiences, then got a set of highlighter pens (a hot commodity at CMU) and the chance to sell it back at any price from 50 cents to $14. The other half were just shown the set and asked if they would rather receive it or get cash. This was akin to a purchase, because volunteers who opted for the pens had to forgo money for them.

Disgust, the researchers suspect, makes people want to get rid of things; they seem to feel everything is tainted. Sadness, in contrast, often reflects loss and helplessness, and so makes people want to change their circumstances. These effects carried over into the experimental marketplace.

Disgust cut people’s selling prices, as the “yuck” factor made them eager to get rid of the pens. Volunteers who felt disgust were willing to unload the pens for only $2.74, on average, compared with the $4.58 demanded by the emotionally neutral fish-watchers. Disgust also reduced buying prices. Reluctant to take on anything new, the volunteers would do so only at a rock-bottom price. Yet they had no idea their feelings were affecting their economic decisions.

Sadness, too, cut people’s selling price, to $3.06, compared with what emotionally neutral volunteers demanded for their pens. Feeling blue made people so desperate for change, even one as inconsequential as getting rid of a few pens, that they held a fire sale. Sadness also raised, to $4.57, the price people would pay for the very pens they were willing to sell for just $3.06. Overpaying seemed a small price for change.

This was a 180-degree reversal of one of the core tenets of behavioral economics. Called the endowment effect, it is the tendency for people to demand a higher price for something they own than they are willing to pay to buy the same item. Psychologically, we place greater value on what we already have. Yet if you’ve ever overpaid for something, you know there are exceptions.

The CMU results may explain why. “Sadness reverses the endowment effect, making people willing to pay a higher price for something than they were willing to sell it for,” says Prof. Lerner. That fits with the common observation that compulsive shoppers tend toward depression and that having a really bad day can trigger a shopping spree.
